Why did the reactor stay hot for so long?
The nuclear fuel in the nuclear reactor would produce a large amount of heat during the fission chain reaction. For example, when these nuclear fuel undergo a fission reaction under the effect of neutrons, one nucleus splits into two and releases two or three additional neutrons. This process usually produces gamma-photons and releases a huge amount of energy. Moreover, after the nuclear fuel rods could not be used in the nuclear reactor for three to six years, they would continue to release radiation for 10,000 years. In this process, energy would also be released, so the reactor could be heated for a long time. In addition, in some reactors, once the fission chain reaction begins, if there is no effective control measure, it will continue to generate heat. However, actual nuclear reactors were equipped with a control system to control the speed of the chain reaction and adjust the power of the reactor to avoid uncontrollable energy release.

How long does it take for the reactor to cool down?
The cooling time of the reaction kettle was affected by many factors and could not be summarized. For example, when testing the cooling effect of the A30-controlled 6L glass reactor, under the test environment of room temperature +20 ° C, humidity 45%, and voltage 230V/50 Hertz, the reactor took 55 minutes to cool from +20 ° C to 0 ° C, and 120 minutes to cool from +20 ° C to-10 ° C. It usually takes two hours to cool down naturally after heating the thermal synthesis reactor. However, if the temperature is around 200 ° C, although water cooling is feasible, it may affect the life of the instrument and the opening of the inner container. It is not recommended. Different reactor types, cooling equipment, control conditions, starting temperature, target temperature, and whether or not to take heat preservation measures would affect the cooling time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is the reactor 201 or 304?
201 stainless steel contains high Manganese, low Ni, poor corrosion resistance, easy to rust;304 stainless steel contains more Chromite, easy to rust, strong corrosion resistance. When choosing the reactor to use 201 or 304 stainless steel, it is necessary to consider the corrosion resistance requirements of the working environment of the reactor. If the working environment is not corrosive and sensitive to cost, 201 stainless steel can be considered; if the working environment has certain corrosive requirements, 304 stainless steel is more suitable. At the same time, we must also consider the standards and specifications of different industries. For example, in industries such as medicine and food that have high requirements for hygiene and corrosion resistance, 304 stainless steel may be a better choice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
It's meaningless to stay in the ICU for long
It was difficult to determine how long one had to stay in the ICU. It depended on many factors. From the perspective of the patient's condition, if the patient's condition was serious, such as multiple organ failure and did not respond to various treatments, it would be difficult to change the prognosis even if the patient stayed in the ICU for a long time. In this case, it might not be meaningful to continue staying in the ICU, but it was difficult to determine the exact length of time. If the patient's condition continued to deteriorate after a period of treatment, and his bodily functions continued to decline without any signs of improvement, it might be difficult to achieve the goal of recovery even if he continued to stay in the ICU. From the perspective of medical resources, when a patient took up a large amount of scarce ICU resources, and other patients who had hope of treatment urgently needed these resources, if the patient basically had no possibility of recovery, from the perspective of rational allocation of social medical resources, the meaning of continuing to stay in the ICU would be greatly reduced. However, there was no clear time limit for this. From the perspective of the patient's quality of life, for example, the possibility of the patient being in a vegetative state and regaining consciousness was very low. Maintaining life in the ICU for a long time would not help improve the patient's quality of life. However, it was also impossible to determine a clear meaningless length of stay in the ICU. In short, it was meaningless to determine how long the patient would stay in the ICU. It was necessary to consider the patient's condition, medical resources, the patient's quality of life, and other factors. The doctor team would make a comprehensive assessment based on the patient's specific conditions. " The Island of Life " is also a wonderful novel. Everyone is welcome to read it!
How long will you stay in the apartment?
There were many options for the length of stay in the apartment. In the short term, short-term lease was generally one month to six months, suitable for temporary residents. For example, there were apartments that could be rented for about 200 yuan a day, which was suitable for short-term living needs. In the long term, long lease contracts were generally for a year or more, suitable for people who lived stably. In some areas, the rental period of an apartment was usually one year, such as in some areas of Shanghai. In the UK, undergraduate students usually rented for 40 - 44 weeks, while graduate students usually rented for 50 - 52 weeks (and the rental period was fixed and could not be changed). In addition, some apartments offered more flexible rental options, such as three months, six months, and so on. In some cases, such as long-term apartments, tenants could rent for three to five years. The choice of the lease term depends on the needs of the tenant and the landlord's policies. Regardless of the length, the lease contract is an important document to protect the rights and interests of both parties. It should be read carefully and abide by the contract.
What are the drugs that stay for a long time?
According to the reference data, the terminal elimination half-life of Azithroobin was about 68 hours, and the "residence" time in the body was relatively long. Budesonate had a very high accumulation rate in the human lungs and a long residence time in the airways. However, at present, only the information about these two drugs clearly mentioned that they had a longer residence time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
