The first part discusses about the effects of the five factors:temperature,relative air moisture,rate of frass sifting,density of larvae,fodder water percentage to growth speed and survival rate of older mealworm (Tenebrio molitor L.) larvae through rotational composite design of quadratic regression. Two models were established to describe the effects of the five factors. The models showed that percentage of fodder water is the major factor that has effect on the growing speed of T. molitor larvae,and fodder water is the major factor on death rate. The models also show that temperature on growth speed,temperature and fodder have important effects on death rate,and the significant test showed they have significant difference on 1% or 5% level. From the two models,by frequency analysis,we can get the optimizing rearing condition,in which the mealworm larvae overweight 10% per day,temperature is 25-26 ,frass sifting rate is once 2-4 days,density of larvae is 0.61-0.79 g/cm2,fodder water is 33.27%-39.71%. And the rearing condition,in which total death rate of T.

第一部分：采用五因素二次正交旋转组合设计，以黄粉虫幼虫饲养过程中饲养温度(X_1)相对湿度(X_2)、虫粪筛除频率(X_3)、饲养密度(X_4)以及饲料含水量(X_5)五因素为参试因素，考查它们对黄粉虫高龄幼虫的生长及存活的影响，建立了以黄粉虫幼虫增重率及死亡率为目标函数的回归模型，并进行了简化： Y_增=127.5079+18.6559x_5+2.7894x_3x_4-2.3854x_3x_5-3.0594x_1~2+1.8241x_3~2-3.8559x_5~2 Y_死=1.7459+0.4108x_1+0.0975x_2+0.9025x_4+0.3442x_5+0.0834x_1~2+0.3060x_4~2-0.2623x_5~2 分析结果表明：影响黄粉虫幼虫生长后期增重及死亡的主要因素分别为饲料含水量和饲养密度；饲料含水量和温度对黄粉虫增重有着重要的影响，饲养密度、温度、饲料含水量对黄粉虫的死亡有着重要的影响，其影响均达1％或5％显著水平；黄粉虫幼虫后期日增重率大于10％的饲养条件为：温度26～27℃、筛粪频率2～4天／次、饲养密度0.61～0.79g／cm~2、饲料含水量33.27～39.71％。

To study the ecophysiological effects of low temperature stress on podocarpus fleuryi Hickel seedlings, two-year-old seedlings were selected as experimental material. We conducted comparative study. On the one hand, seedlings were separately placed in the plots located at the top, half-way-up and the foot of Jinyun Mountain (different altitudes at Jinyun Mountain led to the difference in air temperature) and subjected to winter low temperature stress. On the other hand, in laboratory, seedlings were exposed to simulated low temperature stress which were artificially controlled .

In traditional design for a wire-tube type condenser, the air's temperature around it is considered to be the ambient temperature. In fact, the air's temperature is affected by the distance between the refrigerator's back and the wall and is heated by the compressor and condenser, so its temperature is not equal to the ambient temperature. In this case, the traditional design method is not accurate.

传统的设计冷凝器的方法，是把丝管式冷凝器周围空气的温度当作环境温度，而实际上，由于受压缩机散热、冷凝器加热、冰箱后壁和墙壁之间的间距的影响，冷凝器周围空气的温度并不等于环境温度，因而传统的设计方法并不精确，为了保证设计的精确性，有必要对冷凝器周围空气的温度进行研究。
