It change the normal method for "beginning control" and "goal control". With the development of living level, upholster is dispensability for indoor, the using of decorative material produce plenty of poisonous、baleful chemical substance. These substance make the air indoor into bad, and threaten the healthy in the door if these cumulate .What"s more it will reduce work efficiency. The past method of IAQA is subjective assessment or giving priority subjective assessment. But people will adapt to indoor environment due to settle in the door long-term, which it lead to incorrectness. So, we can"t only use subjective assessment for IAQ. In this article, the author bring forward the best and the reasonable assessing method ,which it is combining the subjective assessment to objective assessment.
随着生活水平的提高,室内装潢成为家居装饰不可缺少的部分,装饰材料的应用,会产生大量的有毒、有害化学物质,使得室内的空气质量变差,且长期累积会威胁室内人员的身体健康,导致工作效率低下,过去对室内空气品质的研究仅用主观评价方法或以主观评价为主对室内人员的主观感受做调查,但是由于室内人员对室内的环境具有适应性,从而造成评价的不准确,且过去对化学微污染物的影响没有定性的研究,因此,用该方法进行评价显然是不准确的,所以,本文提出用主观评价和客观评价想结合的评价方法对室内空气品质进行综合评价。

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%。
