At the end of February, whether it was learning and cultivating, or the preparation of the laboratory was smooth, and the guidance of the study group was also very good.

For them, this is already a huge step forward.

On this day, there is another guidance class, Liu Hai said in the class: "The theoretical knowledge of the first stage has been finished, and you have also done a lot of paper exercises according to the past year's real questions, this stage is mainly to train you to learn to build a physical model to find the direction of the optimal solution, I think this is the most important, let's enter the second stage, experimental design and experiment." ”

The Quanzhou Taixue Academic Competition is a competition limited to two days, because the time is too short, the competition will not go to the laboratory to do real experiments, the experimental stage is usually a simulation experiment, that is, the participating teams do their own experimental design, and then estimate the experimental data by themselves, and then write a paper or a solution to the problem according to this.

When participating in the competition, the contestant team should write down the entire idea and process on paper, and the judges will also score according to the whole.

"Experimental design and experiment, is the part of the answer sheet you have to submit during the competition, which accounts for a large part of the content, this part reflects your experimental literacy, in fact, it has little to do with whether you really solve the problem, when you complete it, you should pay special attention to the previous ideas to do experimental design......

In Liu Hai's view, he divided the guidance course into three stages, the first stage is mainly to teach students how to use the four bits of applied science to solve problems, which is the most important and the most difficult to teach. The latter part of the experiment and the thesis plan part are simple, the four students are all fourth and fifth grade students, and they have already entered the laboratory, written experimental reports and summaries, among which Zhao Lixin and Wang Ming have published papers.

Therefore, the next two stages of the course are mainly to teach students to do experimental design is to stick to the topic, to design every detail of the experimental steps to be rigorous, to write the paper concisely, not to talk too much nonsense, and to be clear and clear in each step.

"Okay, that's all for today's lesson, after you go back, use the real questions we practiced earlier, choose three, and cooperate in writing the experimental design, I will look at it in the next class. ”

Returning to the teacher's dormitory from the office, Liu Hai found that there was a letter from Qilin Mansion in the mailbox at the door.

The person who wrote the letter was Liu Yu, who was studying in Xingling Taixue, the capital city of Qilin Mansion.

Liu Hai took the letter into the door, opened the envelope, and sat in the living room to read.

Liu Yu now asked Liu Hai, the leader of the group, how well, and then introduced some of his studies in school, and then focused on one thing.

As the person in charge of Liu Hai's stay in Qilin Mansion to supervise his assets in Qilin Mansion, Liu Yu has been paying attention to the movements of the two factories in which Liu Hai has a stake, and this time he wrote to Liu Hai, mainly to report to Liu Hai about a related matter about the spiritual fire initiator manufacturing factory in Xinbao Township. Some time ago, she heard that a business group from other states had visited the Linghuo Initiator Manufacturing Factory in Xinbao Township, and it did not attract Liu Yu's special attention at that time, but recently, when she regularly went back to Xinbao Township to check the finances, she heard some rumors, saying that the foreign business group she visited last time seemed to be interested in acquiring the manufacturing plant using Lingshi foreign exchange coupons, and it seemed that the negotiations had been carried out several times.

Liu Yu knew that the team leader had 45% of the shares in the Linghuo Initiator Manufacturing Factory, which involved the interests of the team leader, and even asked Sun Liang, the director of the manufacturing plant, but Sun Liang denied it on the spot, saying that there was a business group from other states that wanted to buy the manufacturing plant, but they refused.

Liu Yu felt that something seemed to be wrong, and immediately wrote to Liu Hai to report the incident.

The more Liu Hai looked at it, the more frowning he became, and when he saw the rumor that it was a foreign business group using the "Spirit Stone Foreign Exchange Coupon" to buy it, he knew that Sun Liang definitely didn't tell Liu Yu the truth.

Spirit stone is one of the most important resources in the world.

All Xiazhou lacks spirit stones, and Yangzhou is the same, don't look at the ordinary people can go to the spirit stone store at will to purchase non-attribute standard spirit stones, and the price is not deceitful, ten gold coins a piece, in fact, this is the government in order to maintain social harmony and stability, has to do it.

Spirit stones involve all aspects of life, especially human cultivation, even if there is a shortage of spirit stones, the Yangzhou government has to do its best to ensure that people can use spirit stones.

In fact, Yangzhou, like other lower states, is extremely lacking in spirit stones, and there is even a consensus in the society, that is, the lack of spirit stones is one of the most important reasons that directly cause lower states like Yangzhou to catch up with Zhongzhou, Shangzhou, and Shenzhou.

In order to reasonably distribute spirit stone resources, each state government has issued its own spirit stone exchange coupons according to its own spirit stone reserves, and spirit stone exchange coupons are required for bulk spirit stone purchases.

Ordinary people seem to be able to buy spirit stones at will, that is because ordinary people can buy a few or dozens of pieces at most at a time, and they will definitely not be able to buy more than they can't buy, which belongs to the welfare of the people who are strictly regulated. As long as it is a slightly larger amount of spirit stone procurement, you need to use the state's spirit stone exchange coupons, go to the special government resource management department to redeem it, if you privately use gold coins to buy spirit stones from the people, more than 100 pieces is an illegal act, more than 500 pieces will be sentenced, more than 1,000 pieces will be sentenced to heavy sentences.

Xiazhou and Zhongzhou usually prohibit the export of spirit stones, and Shenzhou and Shangzhou also have strict limits on the export of spirit stones, and only with the spirit stone exchange voucher in this state can you get the spirit stone export quota equal to the face value of the spirit stone exchange coupon.

In order to purchase spirit stones in other states, the Yangzhou government tried its best to vigorously develop exports to earn those spirit stone exchange coupons in Shangzhou and Shenzhou, but unfortunately, Xiazhou is particularly difficult to export compared to Shangzhou and Shenzhou, and many times, others only use gold coins to settle with you, and would rather pay more fees than take spirit stone exchange coupons to settle.

The spirit stone exchange coupons mentioned here refer to all non-attribute spirit stones, and attribute spirit stones are resources that are not allowed to be exported, even in Shenzhou.

The spirit stone foreign exchange volume mentioned in Liu Yu's letter refers to the spirit stone exchange coupons issued by Shenzhou and Shangzhou.

This thing is a rare thing in Yangzhou, in Baiyu Mansion, if you want to buy good things imported from Zhongzhou, Shangzhou and Shenzhou, it is generally difficult to buy gold coins, and most import stores only do not accept gold coins at all, just accept spirit stone foreign exchange rolls.

Of course, the export stores opened by Yangzhou locals to tourists from other states only accept Lingshi foreign exchange rolls.

Most of the time, Lingshi foreign exchange rolls are the hard currency for state-to-state transactions.

"Sun Liang, they really refuse the temptation of the Lingshi foreign exchange volume? Although the Linghuo Initiator Manufacturing Equipment Factory can bring great benefits, but with the desire of the local people in Yangzhou for the Lingshi foreign exchange volume, I am afraid that it may not be ......."

Bangs frowned, thoughtful.
