On Monday, March 26, the weather was heavily polluted.

Li Hao leaned in front of the window and looked out, and saw that it was the same as the weather forecast, the outside was shrouded in haze, and the visibility was less than 20 meters.

He happily took a few deep breaths, but inhaled a haze, sneezed, and coughed twice.

Zhou Yunsheng looked at the thick smog outside, and she said with emotion: "If only people in the city took the bus to travel, or drove electric cars. I estimate that the number of smog days can be reduced by half, and its concentration will not be as intense. ”

"It's not that people don't like to drive electric vehicles, but there is still a certain gap between the indicators of electric vehicles and fuel vehicles.

Spend about the same amount of money who does not buy a satisfying vehicle. This is also the bottleneck of current technological development, and when our company's iron-graphene battery is put into the market, it is estimated that it can change the problem of insufficient battery capacity of electric vehicles. Li Hao said with emotion.

"Today we are conducting the first smog removal test, and you and I will go with you to see the effect." Li Hao said to Zhou Yunsheng.

Zhou Yunsheng said with a smile: "Of course I have to look at the results, the pricing of this instrument, its cooperation with other companies, and advertising are all things that I am responsible for."

I didn't know what this instrument could do, and I didn't see it in action. How to know it well and give better play to its value. ”

After Zhou Yunsheng finished speaking, she walked into the bedroom and took out two pairs of anti-smog masks from the drawer.

She gently put on a haze mask for Li Hao, and at the same time introduced: "This is a medical-grade anti-haze mask, and it is a little difficult to breathe with it." But it can protect our lungs from smog damage.

Although the lungs have the ability to expel invading the lungs, they use the method of cellular phagocytosis. This exclusion process can be very uncomfortable.

Now smog has become, after smoking, the second leading cause of lung cancer. It is necessary to pay more attention to protection in ordinary times. ”

After Zhou Yunsheng put on a mask for Li Hao, she also put on a mask herself.

Li Hao saw the tenderness in Zhou Yunsheng's eyes, he just felt uncomfortable wearing an anti-haze mask, but his heart was very warm.

It's that after wearing this anti-smog mask, it is a little difficult to speak, and you can still feel difficult to breathe. Deep breathing is required to get enough air.

He felt more and more about the greatness of the high-frequency pulsed electron beam generator he had studied.

They soon came to the company, and Zhou Yunsheng explained the recent events to the company's executives.

Li Hao took the helium balloon flight permission sent by An Bingning. He prepares to release a helium balloon in the park. At the same time, take the big red envelope that was prepared yesterday.

Seeing that everything was ready, Li Hao took the instrument and Zhou Yunsheng downstairs. He saw An Bingning and Qi Baojie, who had already come downstairs and were sorting out the helium balloons.

Xue Xue pointed to the helium balloon and said happily to Li Hao: "Brother Li, I have finished modifying the pod of the helium balloon. According to our calculations, the helium balloon will stay below 5,000 meters in the air, and the instrument will not be turbulent. Not exceeding this height, my design protects the instrument for maximum stability. ”

Li Hao was very satisfied with their work, and he handed the prepared red envelope to everyone in the meteorological project team.

An Bingning and Xue Xue's red envelopes are more valuable, and they have put in more effort than others. The finish is also better.

Inside the red envelope is some money and small gifts he made.

After everyone thanked them and took the red envelope, Xue Xue opened it and looked at it, she said in surprise: "Brother Li, this money is too much." I can't ask for it. ”

All this money has caught up with her tuition and living expenses for two years, and she only wants to earn a small amount of money by participating in this program. I didn't expect Li Hao to be so generous.

Li Hao said with a smile: "Let's take it, you have also put in a lot of effort for the success of the project." Don't be polite to me. ”

Everyone happily accepted the red envelope given by Li Hao. The money I have worked hard to earn is very safe to spend.

"Everyone got on the bus, we were going to go to the park not far from here, I don't know why the district environmental protection bureau was so enthusiastic, and also helped us contact the park and the public security department to provide us with a venue." Li Hao thought of yesterday's events and said a little strangely.

Zhou Yunsheng pursed his lips and said disdainfully: "You still don't understand this question, there is an automatic air quality detection device near this park." It is linked to the Ministry of Environmental Protection's monitoring system.

As soon as you have this instrument useful, the air quality around this instrument immediately improves. They will be complimented by their superiors. It's just that it doesn't work, what should have happened has happened, and they don't have anything to lose. ”

"So that's the case, I said there is no stakehold, how can they be so enthusiastic." Li Hao suddenly realized.

They packed up their utensils and drove towards the park. Get ready for a hot air balloon release.

Soon they came to the park, with the cooperation of the park management. Find a stone pier that holds the helium balloon to life.

They began to sort out their instruments and prepare to release the helium balloons that had been prepared.

Li Hao took out a signal transmitter, which is used for communication between the mobile phone and the instrument. The helium balloon rises too far and needs to be redirected with a professional instrument.

Seeing that everything was ready, he instructed them, "You can release the helium balloon, we are going to conduct the first experiment." ”

Wei Wu was in charge of releasing the helium balloon, and An Bingning was holding a digital video camera, ready to shoot the scene of the test. Qi Baojie held a multi-functional detector to detect various changes in the surrounding data in real time.

Not far from them, Jia Hong and Hu Yu were walking.

Hu Yu frowned, and said in a dissatisfied tone: "Lao Jia, why are you so machismo, you actually deprive me of the right to broadcast live." ”

"Broadcast live broadcast, and if it is broadcast live, it will become a prairie above my head." Jia Hong said resentfully.

Hu Yu immediately pushed Jia Hong, pouted and said, "What are you talking about?" You're jealous, isn't it just that a local tyrant gave me a gift. ”

Jia Hong said in a firm tone: "We broadcast live in a dignified manner and make money seriously. I don't know what they want to do with the gifts, but they just want to get together offline. What does that mean exactly? Obvious. ”

"I promised the fans to broadcast live today, how bad it is to release their pigeons." Hu Yu suddenly saw Li Hao and them working.

"Hey, that's not our upstairs company. What are they doing? The last time they were live, it was really good. I'll broadcast them live, you won't be jealous. Hu Yu asked her boyfriend.

"This is nothing? It's not an open ball. Jia Hong thought about it and agreed.

Hu Yu took out his mobile phone and started the live broadcast.

"Everyone is welcome to watch the live broadcast of Xiaoyu and take a walk in the park today. Suddenly I ran into a tech company upstairs with us. I don't know what they're doing in the park? I'll give you a live broadcast to reveal the secret. ”

Li Hao saw that the helium balloon had risen into the air, and it slowly flew to the designated place. After that, secure the rope.

Li Hao checked the situation of the instrument through the mobile phone software and found that he was in good working condition.

He directly turned on the dehaze mode for the instrument. Images from the camera on the pod can be seen emitting blue light around the instrument.

As the blue light intensifies, it begins to dissipate in all directions. It's just that it's at most five meters away from the device, and then it doesn't spread anymore.

Li Hao knew that this effect was a phenomenon caused by the interaction of electric charges after the water molecules in the air were hit by an electron beam.

They waited 20 minutes before realizing that the haze around the helium balloon had settled. There were gray-black raindrops that began to fall. It is conspicuous to fall on their clothes.

What does this phenomenon seem to initiate? The raindrops were falling faster and faster, and soon the gray-black raindrops continued to fall like a light rain.

At a speed visible to the naked eye, the sky became clear.

People living in Haidian District found that after a black rain. The sky has become clear, and the haze has completely dissipated.

Citizens who did not know what was going on questioned the Central Meteorological Observatory online.

"Why is there a black rain in Haidian District, your meteorological observatory doesn't do anything with funds, is there another major environmental problem, is this acid rain or something? Does it have an impact on us? You didn't even give advance notice. ”

"I prepared a number of anti-smog measures, but there was no smog at all when I went out in the morning. Even the haze can't be reported accurately, and the weather is really bad. ”

Due to a large amount of criticism and the monitoring of atmospheric anomalies at the same time, the Central Meteorological Observatory acted quickly and quickly understood the situation, and he urgently issued an announcement.

(Grievances) This pot weather is not back, this is a technology company using high technology to do haze removal experiments. The black raindrops are a combination of the falling haze and the water. Being dropped by the black rain will not have an impact on your health as long as you wash it off.

At the same time, the Central Meteorological Observatory released a meteorological cloud map.

I only saw that the weather cloud map in Yanjing in the morning was still gray.

The satellite image of the present moment, the rest of the place is also gray. It's just that in Haidian District and its surroundings, a huge hole has appeared.
