The quadrupolar ring's temperature field is studied numerically by finite difference method, its null drift is analyzed at given temperature circumitance.

通过有限差分法，对光纤环的Shupe效应作了研究，对四极子光纤环在非稳态传热的过程中的温度场进行数值求解，分析了光纤环在试验提供的温度环境下的温度零漂。

And therefore it avoided the phenomena that makes waster ratio to be higher caused by overhigh or lower temperature.

文中讨论台达温度控控器在塑料加工生产过程中的具体应用，以保证在复杂生产环境中精确地控制原料生产温度，避免温度过高或者过低造成废品率高的现象。

The optimum temperature s and pH were(40℃,2.4)for stomach,(55℃,7.6) for pyloric caeca(45℃,8.0) for gut. The optimum temperature for protease activity was higher than that in the fish body. The highest activity of protease occurred in strong acidic condition in stomach,but in neutral or weak alkaline condition in pyloric caeca and gut.

蛋白酶的活力随温度和pH变化呈现一定的规律性，不同消化器官蛋白酶的最适温度、pH依次为胃(40℃，2.4)、幽门盲囊(55℃，7.6)、肠(45℃，8.0)，蛋白酶的最适温度高于体温，胃蛋白酶在强酸环境下活力最大，幽门盲囊与肠在中性和偏碱条件下活力最大

From the viewpoint of energy efficiency of cooling towers and underground thermal balance, recommends the operating mode by setting the average water temperature of buried exchangers or by setting the difference between the water temperature of buried exchangers and the wet-bulb temperature of environment.

从冷却塔运行节能及地下冷热平衡的角度考虑，建议采用设定地埋管换热器流体平均温度或设定地理管换热器流体温度与环境湿球温度的差值的控制策略。

By the measurements of inlet temperature, outlet temperature, ambient temperature and solar irradiance on aperture plane per unit area the characteristic parameters of the transfer function can be obtained.

在改进后的模型中，将集热器看作是一个系统，集热器的出口温度是系统的输出，其余变量：集热器进口温度、环境空气温度和落在集热器采光面上的太阳辐照度看作是系统的输入。

The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.

结果表明，在生长季节内，林内温度低于林外温度，林下人参生长发育较差，产量较低；林分郁闭度为0.7~0.8时，人参的净光合速率、株高、单根重、叶绿素含量等指标较高；而郁闭度过高或过低都会影响人参生长发育；随着人参年龄的增加，净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求，为林下人参生长发育提供最适宜的生态环境。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
