Chapter 152 (2/2)
It was when running by the early stall, watching Shen Yiyun, who ate the bun alone, was a bit scary.
Unfortunately, such a heaven like day, even if there are thousands of reluctant, has been close to the end.
Finally, on November 20, at 1 p.m., all the members of the training gathered again to the big laboratory.
40 individuals, according to the random number of the selected, each stood in front of their own experimental platform.
Although most people have been mixed up, few people speak at this time.
Between speechless, the atmosphere was a little dignified.
The final experimental test is about to begin.
This exam, everything goes according to the regular process.
The experimental scores, together with the theoretical results of the preliminary game, ranked the top 13, officially became a member of Jijing provincial team, and went to the final of eastern Shandong on December 1.
At least the open process is like this. If there is so-called ”ordinary score” or ”subjective score” of huzengwu, there is no way to get it.
In a dignified, Li Zheng, Wu Shu and ouxingjiao were far from a look, all of which were some of the unspeakable anxiety.
Others only said that they were three to provoke huzengwang, and then I knew that I was afraid.
Only they know why they are anxious.
After a few minutes of silence, a series of scattered footsteps came from the corridor.
Then, the examiner Hu Zengwu, led more than ten teachers and assistants, and entered the classroom.
It was the first time Li Zheng saw him after the previous contradiction.
Hu Zengwu did not see Li Zheng, and when he stepped on stage, he lowered his head and repeated the requirements of the experimental examination according to his manuscript.
”The time for the exam, three hours.”
”Points are deducted for an extension of time, up to 4 hours.”
”It is forbidden to leave the stadium if there is no special situation in the middle of the way.”
”Please wear gloves and protective glasses when using concentrated alkali solution.”
”It is forbidden to talk to other candidates all the time. Please consult the examiner for any questions.”
”The final score of the experiment consists of result score, operation score and other scores.”
”Finally, please read the instructions carefully.”
Hu zengwang, please, and look at the whole scene.
”This experiment will also determine whether you can enter the provincial team.”
”If you have any questions, say it now.”
After seven or eight seconds, when nobody spoke, huzengwu made a gesture to the left and right.
The examination officially began.
Li Zheng got the test paper and raw materials, only a rough scan, and he was shocked.
[lead oxide by Lede powder waste residue method]
is this not the true problem in 1998?
I am ashamed. Li Zheng and Shi Yang spent the past few days together to pass through the real problems of the national decision experiment in 20 years. It will be 98 years, and I don't know it in the first year
But this is the last thing that happened in 98 years.
As for this problem, although it is terrible, it can not be separated from its ancestor.
Or leaching, filtration, transformation, drying that set of processes, dissolve to filter, all play spit.If you remember correctly, I made 83% of the yield at that time, and Shiyang was 92%.
The later titration and purity tests were routine and yawned.
Now to do this problem, it is really difficult to make mistakes
Plus these two days with Wu Shu and Ou xingzhuo all kinds of violent wind, now this feeling is hot, Li Zheng is a little embarrassed.
But even if he was so confident, he did not dare to be careless. Before he started, he went through the whole process in his mind as before, trying to find dangerous steps.
Well, No.
There's nothing to think about. Let's go.
While waiting, Li Zheng glanced around the examination room from time to time, not curious about other people's progress, but simply worried about something.
He also saw clearly that this examination was much more serious than the first one. There was an examiner behind every four students, who examined and recorded every step of the examinee in real time.
Hu Zengwu, as the examiner, did not make special treatment this time. He inspected the whole examination room and gave some information to the examiner from time to time.
Now it seems that he probably won't do anything in such a serious examination.
During the next examination period, some people broke the reagent bottle, some left the field ahead of time, some did it hard and some were in a daze.
Those who take the edge of the province into the training, eight Chengdu just died.
About half of the top 20 are relatively stable.
Of course, none of them is as stable as Li Zhengwen.
At 1 hour and 50 minutes, Li Zheng got up steadily and submitted all the products and reports to the examiner behind him.
This male examiner is very young. He is probably a graduate assistant. After receiving the report and several products, he quickly fills in the score sheet. During this period, he repeatedly nods: ”yes, fast and stable, and the operation score is not deducted. Let's go for the national decision.”
People around him scolded Li Zheng for this force, while grasping the experiment.
Li Zheng looked at the painful expressions of his classmates.
Gradually realized.
Unconsciously.
Step by step, they have become the kind of people who used to hate most.
That is, Lin Yujing.
At this time, he just understood Lin's distress.
The true meaning of ”and”.
No way, my friends
I don't want to do it so fast.
But strength doesn't allow it.
Just as Li Zheng was getting ready to go out, Shen Yiyun suddenly rushed in.
It's not a run, it's a rush.
She rushed to Hu Zengwu's side all the way, holding the platform to stop. The whole person was obviously out of shape. She whispered to Hu Zengwu, but it spread all over the classroom --
”Shi Yang! Shi Yang is coming with a hanging bottle
