When the foreman saw that Yang Fei was so full of words, he didn't dare to take the bait, and said: "If you can say it, it shows that you have the ability, but whether it works or not, you have to pass the test of practice, and most importantly, it has to be affirmed by our boss." If our boss says okay, then don't say invite you to drink milk tea, even if it is to invite you to dinner, I am willing. ”

Yang Fei smiled, thinking to himself that she was a cautious girl, such a girl, if she doesn't see a rabbit or an eagle, it will be difficult for ordinary men to hook up.

"You only see the workload, but you don't think about the productivity. Work efficiency is an important indicator to evaluate work ability. The so-called work efficiency refers to the ratio of work output to input. If the output is greater than the input, it is a positive efficiency, and if the output is less than the input, it is a negative efficiency. Yang Fei talked eloquently.

The foreman laughed and said, "Don't talk too profoundly, we only have a junior high school education, so we don't understand." ”

Yang Fei smiled helplessly: "Okay, let's talk about the workload." Workload, which is equal to the efficiency multiplied by the number of hours worked. Your working hours are fixed, so whether you can achieve the maximum output depends on the work efficiency. Still don't understand? So I'd better be practical. ”

He pointed to a few people working inside: "You see they are busy, like a spinning top, the workload is very large, but the efficiency is very low. You just said that if everyone divides the work, they are afraid that the workload will not be equal, and this problem is actually very easy to solve. ”

"All the spices can be prepared in three equal portions, divided into the left, right and front three workbenches, and then the staff is divided into three groups, each team is responsible for a workbench, and the orders you receive, no matter what you buy, just distribute them one by one according to the working group. For example, the workbench is divided into three groups of ABC, and the first order you receive is assigned to group A, the second order is assigned to group B, the third order is assigned to group C, and the fourth order is assigned to group A. Cycle in turn. Because they have all the seasonings, they can make them out quickly, no matter what they want to mix. Do you understand that?"

The foreman suddenly realized: "I understand this time." Hey, this method is good, at least you don't have to run around, it saves a lot of time, and the efficiency can really be improved a lot. The students of Qingdao University are really smart. ”

Yang Fei smiled: "If your boss adopts it, remember to invite me to dinner!"

The foreman giggled and said, "I'll talk about it then!" You can bring more classmates over to buy milk tea! Otherwise, I want to invite you to dinner, and I can't find you." ”

Yang Fei and the others left with milk tea.

Jiang Xiaojia plugged in the straw, took a sip, and said twice: "It's delicious, this is strawberry flavored, there are really strawberries!"

Yang Fei smiled: "Of course, otherwise it can be sold so hot?"

Jiang Xiaojia said: "Do you have to drink it in Southern Province?"

Yang Fei said: "I'll have to drink soon." ”

Jiang Xiaojia said: "I want to drink it every day, but I don't have any money." ”

Yang Fei said: "The milk tea you want to drink in this life, my brother will help you pack it!"

Jiang Xiaojia smiled sweetly: "Really, thank you, Brother Yang Fei." ”

It's okay in the afternoon, Yang Fei took her to a few famous scenic spots in Beijing, the current capital, not like the first in later generations, the traffic is relatively smooth, driving a car, swimming around the city, it doesn't take much time.

In this era, construction and urban construction are being carried out in various places. But the designers' vision is not yet to see that in a decade, private cars will develop so rapidly that the entire city will be turned into a parking lot.

How difficult is it to have a forward-looking vision and dare to achieve an advanced layout?

Therefore, the Chinese people are grateful to the old man who drew a circle by the South China Sea.

It is precisely because of his wisdom and greatness, his foresight and insight, that the country has become rich and strong step by step.

In the evening, Yang Fei had dinner with Jiang Xiaojia and sent her on the plane, the little girl was reluctant, and hugged Yang Fei before leaving. Yang Fei patted her on the back of the head and said don't be afraid, your parents will come to pick you up at the airport.

Sending Jiang Xiaojia away, Yang Fei returned to school.

Su Tong went back to Southern Province to deal with work, and he didn't bother to go back to his room to live alone, so he lived in the dormitory.

The dormitory conditions of Qingda are good, although they are not as comfortable as their own homes, but they are popular, and there are young students everywhere.

Yang Fei came to the laboratory of the Department of Chemistry, where several research groups are related to the research project of Jiebai, and the people in the research group are all juniors and seniors, and they have a solid grasp of professional knowledge, and can carry out research work under the leadership of their supervisors.

These tutors, in their respective professional fields, are all Dana-level existences, and the domestic academic research in chemistry is controlled by these people, and they also rely on them to win glory for the country in the world.

Yang Fei walked into the laboratory and saw Zhu Lin arguing with another boy, and the two were discussing the shampoo formula list.

People of all ages have different memories of washing their hair.

The "post-70s" use soap, and some people even use laundry detergent!

The "post-80s" generation has big-name shampoos such as Rejoice and Head & Shoulders, and they can choose freely for different hair types and needs.

The "post-90s" generation has a variety of products to choose from, such as magic weapons such as leave-in spray.

When everyone washes their hair, they will have a question, that is: is the quality of shampoo with more foam better?

Now, it is this question that Zhu Lin and her classmates are arguing about.

Zhu Lin thinks that shampoos should add surfactants that are easy to foam, and even specially add foaming agents to keep them foamy.

Boys think that the effect of shampoo is to wash clean hair, just like washing clothes with laundry detergent, and now the preparation process of surfactants can already produce low-foaming, or even non-foaming surfactants, which can also clean oil well, but only little or no foam is produced. Since they are the same in terms of efficacy, why do you have to use high-foaming active ingredients?

Two people have their own opinions, and they can put forward a lot of truths, and no one can convince anyone.

The others also participated in the discussion, divided into two factions, and almost had a debate.

At this time, Zhu Lin saw Yang Fei coming in, so he greeted with a smile: "Yang Fei, you came just in time, you give us a comment, who do you say is right and who is wrong?"

Yang Fei touched his nose and said with a smile: "The most difficult thing in the world is to distinguish between right and wrong. But what people are most obsessed with is also the distinction between right and wrong. I feel that there is no one right or wrong in this matter. But for this project, we have to use a high-bubble recipe table!"

The boy glanced at Yang Fei and said, "This classmate, you are not from our research group, why did you come in? Why do you say that you must use a high-foam formula? This is not what you say!"

Zhu Lin pursed his lips and smiled: "This matter is really up to him!

The boy didn't know Yang Fei, and said coldly: "How is it possible? He is not even a member of the research group!" 8)
