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％。

Sixty-nine years ago today, a ghost word was outed from its hiding place on page 771 of Webster's New International Dictionary, where it had spent five comfortable years. Dord started life on a slip of paper prepared by the lexicon's chemistry editor, who noted that "D or d" was an abbreviation for density. A serendipitous misinterpretation saw the entry being read as a single word, dord, and it was accordingly registered and printed up as a noun with the meaning "density." No proofreader caught the error, but five years later an editor noticed the word had no etymology and began the investigation that led to the word's being banished.

六十九年前的今天，一个谜一样的词被世人发现，这个词在韦伯斯特新国际字典的771页整整藏了5年Dord一词因为一张小纸片而开始了它的生涯，这张小纸片是由lexicon的化学主编准备的，他标注出了"D or d"是密度的缩写这条记录很偶然的被认为是一个完整的单词，dord之后它被作为一个名词收入词典并印刷出来，意思是"密度"所有的校对人员都没有发现这个错误，但是五年后，一名编辑注意到这个词没有词源，然后他开始溯源并最终将这个词从词典中去除
