Fang Huai's throat was choked and he sat down.

In the rest of the time, he listened to the lecture while his mind wandered.

The religious officer said that he was indeed not ready.

Before handing in this series of proposals, he thought that there might be a defense stage in front of the expert group, and he also thought about how to prepare theoretical knowledge.

But from the beginning of the program, everything was so smooth that he ignored the problem at that time.

At this point, the faculty member said that the leader had shown the plan to their teaching and research group.

I don't know which leader it is, whether it is the leader of Yu, or the leader of Chen, or something else.

He regretted a little, the leader gave the teaching and research group, the expert's conclusion, will not affect the leader's judgment.

The current plan, not to mention theoretical support, does not even have a catalog.

The instructor's conclusion is right, he really hasn't studied the theory very systematically, many times, it is what needs to be checked, combined with his own understanding of the future, as long as he thinks it is right, he will use it.

In the meantime, there are some changes in my thinking, with the improvement of my position, I even began to want to change the fate of the entire fire brigade, from a slight leftist, to a more radical hawkish ideology, a set of things that have been done in this way, chaos, is also certain, and there will even be some inconsistencies.

And the idea of a system is to put everything in order, and slowly organize it into a book from all aspects, this plan was originally to think of doing one step at a time, more than half a year, and training, how can there be effort to slowly regularize.

It's too much worse.

It's a matter of whether you pick peaches or not, but you really don't need to guide this matter.

Especially for such teaching and research personnel, let alone teaching and research groups, there are many people who can guide, and they have to play a battle with conservative experts before reporting their ideas, wasting a round of time.

Time is the most precious thing.

He had to prove himself better than the theorists.

On stage, it's still talking.

However, Fang Huai said well just now, the three elements of fire are the key to controlling the fire.

It's just that he is still a little general.

Temperature, and oxygen supply, we can control one of them, and we can suppress the fire, or even extinguish it completely.

How to control the temperature, we already talked about it in the last lesson.

Accurate water injection is the key to cooling down and controlling the fire, and it is also the premise of carrying out internal attack in the burning fire.

Comrade Fang Huai, you weren't there in the last class, do you know how to conduct fire investigation in several parts? ”

Fang Huai was thinking about something when he heard the instructor call him to turn on the microphone again, and his pupils shrank slightly.

Fuck, a bit excessive, right?

I asked myself one after another, if I don't let you get some light, this thing can't get over?

Fang Huai stood up helplessly, and a probability master sitting in front of him laughed so hard that his back twitched.

Sure enough, there is only one one who suffers, and luck will take care of most people.

The preliminary investigation of the fire, the theory alone, he gave a whole class two days ago, and there were many and miscellaneous, how could it be that Fang Huai didn't know? Few of you who have listened to the lecture can fully explain it!

Fang Huai gritted his teeth, his heart was calm, and he paid attention to his problem.

After a moment, he replied: "If I want to divide it, it should be two parts: distant reconnaissance and arrival reconnaissance."

Distant reconnaissance is to judge the fire and wind direction, which will affect the next step of the spread of the fire, this step, only need to be felt with the eyes.

Detection is to determine the specific location of combustibles and fires, and this step uses all our senses, fire can be heard, and heat can also be felt through the body.

Therefore, in this step, it is necessary to first observe the building in a circle as much as possible.

If there are trapped people, the first thing you should judge is the signs of life, such as the figure by the window, the handprints left on the window, the messy blinds, etc.

If there are no trapped people, it is necessary to first observe the fire floor and smoke concentration, find the entry point, whether there is a chance to shoot water from a long distance to cool down, etc., and set up the water separator position and internal attack tactics, relying on the judgment of the fire layer and the fire......"

Fang Huai kept adding and spoke in detail.

To be honest, his experience in the fire field is not small in his previous life alone, and extinguishing fires is an old profession, and he has a kind of self-confidence.

Therefore, in his life, he focused on emergency rescue and multi-disaster disasters, and did not have much time to read about fires.

At this moment, I can only pour out what I know, just like doing liberal arts questions, Lao Tzu can always touch the right two by answering more, right?

The surrounding students also nodded their heads one after another.

Well, that's right, when I hear it, I often go in and out of the fire.

However, when Fang Huai had answered for nearly a minute, the religious officer raised his hand and stopped him.

"It's still a problem, there is a lack of professional theory."

Fang Huai suddenly quieted down, and the surrounding students were also a little confused.

These things, which have been passed down from generation to generation of firefighters, are they not professional?

Seeing everyone's expressions, the religious staff pushed the glasses on the beam, smiled, and his voice changed from a flat tone just now to a loud one.

"Lack of theory, this is your common problem, our grassroots backbone, often through experience to judge the problem, but without systematic guidance, your thinking is not systematic, it will lead to mistakes and omissions, ignoring some key factors.

For example, fire reconnaissance, what did we talk about in the last lesson? ”

The religious member reflexively wrote on the blackboard:

visible, with invisible signs.

"These are the two categories of fire investigation."

After the religious clerk finished writing, he threw the chalk on the table and said with a smile:

"This is connected to this lesson, and when the first battle force arrives, the type of building is determined, starting from the planning stage and becoming specific when a fire breaks out.

After judging the structure of the building, Fang Huai was right, and observed around the field.

First, there is the smoke. ”

The religious clerk picked up the chalk again and began to write on the blackboard.

"In the observation around the field, the smoke form partly explains what the main combustion material is, and as for which combustion material corresponds to which smoke form, there is a book on it, so we will not go into details.

In addition, the direction of the flue gas is also important.

When you find that a building has smoke exhaust on one side and a vent on the other side, but there is no smoke, then it means that this is an air intake.

So in the observation around the field, we can dispose of it, that is, the idea is to close these vents, modern buildings are usually limited in ventilation, reducing the internal oxygen intake, which can effectively inhibit combustion.

If an obvious flame emerges from the field when circling the field, the gun can be quickly fired to suppress the flame exit to achieve the purpose of rapid fire control and cooling.

This is the efficiency to be reflected in the circumambulation.

So what if there is no smoke or fire?

Then you have to use a thermal imaging instrument to judge, the extremely high thermal radiation of the fire source is enough to make any intact thermal imager show its form, but so far, I have not seen this instrument play its correct role, your subconscious judgment of this thing, is the instrument used to search and rescue trapped people. ”

There was a lesson in the tone, but everyone was silent.

It's a fact.

It's not that it's not useless, the drill is still commonly used, and when the fire is brought out at the door, it is easy to be laughed at by the people.

Ordinary people will not think you are professional.

What's the matter, you can't see the fire? If you don't hurry up and save it, what are you doing here?

"I know what you are thinking, I think it is not practical, and it has delayed time, but your identity is about to become a commander, please change your thinking, you must understand the theory."

The religious clerk said, looking at Fang Huai:

"Especially you, Number One, what you write out is influencing decision-making at the top."

As soon as these words came out, Fang Huai became the focus of the audience's eyes again.

I wiped a mother-in-law, can he influence the decision-making of the upper level?

In their eyes, Fang Huai became unfathomable.

And what is even more unfathomable is the religious member on the stage, because he can teach Fang Huai so much that he can't answer the phone.

Fang Huai's heart felt like eating.

Big brother, have you seen my stuff? Why do I keep talking about emergency rescue, big emergency, when did you mention fire?

I'm pretty sure about our army's firefighting capabilities, okay?

You're holding on to the fire.

Seeing that Fang Huai was speechless, the religious staff had a little smile on their faces, as if they had seen the benefits of a decision that the leader valued under the guidance of their cadres.

In fact, he hadn't seen Fang Huai's plan, but when Fang Huai reported in the big competition, a leader who was familiar with several instructors was present and talked to them about some content and thoughts on this plan.

The leader's evaluation was: Big decisions are just a bit messy.

Also, the director may be tempted.

This can't be touched?

Since they learned of this situation, many people in the teaching and research group are secretly concerned about the enrollment of Fang Huai, a student, today the religious staff is just a front station, and soon, there will be Zhao Qiansun Li teacher, whoever wins Fang Huai, and who is the leader of the guidance group.

Fang Huai didn't know this, but he knew one thing.

Don't come to the sidelines.

It's a very clear thing, don't get pickled, only the leaders who provide practical support are eligible to leave their names on the program.

"Know what it is, know why it is."

The religious staff stood on the stage, naturally did not have time to observe Fang Huai's expression carefully, which proved Fang Huai's lack of theory, and began to continue the class.

"In the process of investigation, we should pay attention to listening, the high-pressure state of the fire field, there will be the phenomenon of gas pulse flow, tremor, often accompanied by whistle, shooting water to the high-pressure position, often achieve good results......

In this class, everyone listened very carefully.

Because the information revealed by the religious staff grabbed everyone's attention.

The religious staff also spoke very freely.

The victim was only Fang Huai.

Fang Huai really wanted to listen to the lecture with a calm mind, because in the explanation of the religious staff, there were indeed a lot of dry goods for him.

But this instructor always likes to use "we have talked about XX lessons" to refer to something, and he does not repeat what he has said, because of the lack of the previous class, Fang Huai's spirit is concentrated, and the content is also a little interrupted.

This kind of lecture is a loss forever, like a traffic light in the city, once you don't catch up with this green light, the next light is likely to be red.

The thick theory book of hundreds of pages, Fang Huai probably flipped through it, and there were too many cases copied, both at home and abroad, and it took a lot of time to read through, and it was a big job to find the key points from it and memorize it.

If you don't memorize it, I'm afraid that the person on the stage will continue to play tricks, saying that his theory is not solid, this is still a figure who can contact the leader, and when the time comes, I won't rub it, and I won't be embarrassed today, and tomorrow I will be able to make the leader smile lightly and feel that my foundation is not solid.

These little things can sometimes be quite fatal.

Forget it, let's hang it.

Fang Huai let out a breath of helplessness in his nose and began to search for relevant knowledge in the system.

Fire Dynamics, 25 points.

Fire Causes and Prevention, 20 o'clock.

"The Use and Origin of New Fire Extinguishing Equipment", 10 points.

55 points, too expensive.

There are a lot of exchanges about urban fires in the system, and these are only three pure theories selected from a dozen categories of knowledge.

Merit: 68.3.

Fang Huai suddenly realized that after the exchange, there were more than a dozen military merits left, which was definitely not enough, and that first-class merit was afraid that it would be demolished.

Exchange.

The words of the religious staff continued.

"It is particularly important to observe above the neutral surface of the fire, as the temperature difference will lead to an increase in the smoke velocity, and if the flue gas velocity reaches a turbulent state, then the fire is already in a violent state.

Because the smoke spreads outward from the ignition point, the location of the ignition point can also be quickly determined through the direction of the air flow.

Why do you use thermal imaging cameras more? By observing the morphology of the smoke with a thermal imager, it is also possible to trace the flow of the smoke and confirm the location of the fire.

Okay, don't move the blackboard, give you ten minutes, take a break, go to the toilet when it's time to go to the toilet, take a look at the following content, and we'll talk about gating technology in a moment. ”

The religious clerk walked straight out of the classroom, and there was a sound of relief below.

What atmospheric pressure, air pressure difference, Pi curve, Po curve, make their heads big, speak quickly, and if they can't understand a few words, the content behind them begins to buzz in their heads.

Obviously they are veterans of firefighting, and they are the easiest to understand fire fighting tactics class, but the religious staff keep mentioning the content of fire theory classes today.

"Rub, isn't it quite simple for religious staff to give lectures in ordinary times, how does Lao Tzu feel that he is listening to the book of heaven today?"

"I just felt that my deceased high school math teacher Huang is alive again..."

Fang Huai also came back to his senses from the explosive information that suddenly came out of his mind, touched his head and smiled.

To be honest, he only knew a little bit about what he talked about today, but now that some more advanced theoretical knowledge has entered his mind, he suddenly feels that the previous fire scene breakthrough arrangement is indeed too reckless.

But...

Fang Huai opened the book and began to compare some knowledge.

In front, a few people from Class 9 took advantage of this opportunity to come over and looked at Fang Huai with a look of surprise.

"Fang Huai, what are you that alarmed the upper leaders?"

"Yes, how many leaders at the top? Schools? ”

Sun Ning, nicknamed the big guy, smiled: "Man, your vision is too narrow, the religious officer's eyes are above the top, and he talks about his experience of studying in Hong Kong and BJ at every turn, and the upper-level leader he said, how can it be a school!" It must be in the bureau! ”

At this point, there are at least twenty pairs of ears around it.

Fang Huai shook his head, flipped through the book with a smile, and turned to the page of "Fire Ground Internal Attack and Gating Control Technology", and then looked at it intently.

Xu Jiang saw that he didn't answer, and said a little speechlessly:

"You see, he's just pretending to be mysterious! It's suitable for calling a stuffy donkey! ”

Jin Guotao looked serious at this time, patted Fang Huai, and said:

"That religious officer... You don't have any holiday with him, do you? How do I feel like he's targeting you a bit? ”

Fang Huai glanced at ten lines, and when he heard this, he almost finished reading what he wanted to read, so he closed the book, looked up and smiled:

"I don't know, what can I do, people want to test me, it's my honor."
