The first stage is screen experiment. A 24-1 Fractional Factorial Design and resolution IV experiment is used to find out which main effect and interaction effect have obvious influence on the precision positioning of feeding table by these four factors. The Minitab program including Half Normal Plot, Pareto Chart, and ANOVA is applied to diagnose obvious effects. The second stage is optimization experiment. The fitness of regression model is obtained by using CCD of RSM with statistical hypothesis testing, regression analysis, lack-of-fit testing, and residual analysis. The optimum values can be found out by using response surface plot and contour plot.

在第一阶段为筛选实验采用24-1部分因子实验，解析度为IV，求出这4个因子主效应及交互作用哪些会对进给平台定位精度有显著的影响，在分析方面使用统计软体Minitab做初步分析，应用了半常态机率图、柏拉图与变异数分析来判断出显著因子与交互效应显著，第二阶段优化实验采用反应曲面法的中央合成设计，搭配统计检定、回归分析、缺适性检定(Lack-of-Fit)、残差分析来取决回归模式之合适性，最后根据反应曲面图及等高线图求出最佳值做验证实验。

The orthogonal design of fifteen factors and two levels is made. At the same time, fifteen components are tested and five key factors have been selected out .Finally the second orthogonal design of five factors and four levels is carried on and the new optimum component of artificial diet of rice stem borer is reached.

同时，本文从已报道的不同二化螟人工饲料中选择了15种饲料成分，采用15因子2水平的正交试验设计，对这15种成分进行了优化，并从中筛选出5个关键因子，然后对这5个关键因子进行了5因子4水平的第二次正交试验优化设计，得出了二化螟人工饲料新的优化配方。

Acanthosis nigricans has received attention as a type 2 diabetes sign, but Dr. Bennett noted that this dermatologic condition may simply indicate increased insulin resistance. He emphasized that children with type 1 diabetes do have symptoms, while those with type 2 usually do not. Hispanic children, African-American children, and those of Polynesian heritage also seem more vulnerable to developing type 2 diabetes than white children, although obesity and being female clearly increase the risk in all ethnic groups, he said. Currently, there is no direct evidence that physical inactivity, separate from its effect on body mass index, is a risk factor for type 2 diabetes in youngsters.

黑色棘皮病因为是第二型糖尿病的一项病徵而受到瞩目，但Bennett医师表示，这种皮肤疾病可能仅代表胰岛素抗性增加；他强调，这在第一型糖尿病的孩童身上会有此症状，第二型糖尿病则否；他指出，虽然肥胖者与女性在所有种族中有明显地第二型糖尿病增加风险，但西班牙、非裔美国籍以及波里尼西亚人孩童比白人孩童更容易发生；目前没有直接证据证明，来自於缺乏运动对身体质量指数的影响，是造成年轻人发生第二型糖尿病的危险因子。

These factors are likely contributors to the "second factor" that predisposes to the development and progression of AF.

这些因素很有可能构成一个&第二因子&并导致病人有患发房颤的倾向。

At the same time, comprehensive assessment and classification of varieties were done. The result showed that 8 characters were loaded on 5 main factors. The first were intergrated factor of fruit, including single fruit weight, pulp thickness, edible rate and contents of soluble solid state material, From the second to the fifth factors, it reflected the fruit texture, mature period, fruit pit weight and flavor, respectively. The accumulation variance of five main factors contributing to the 8 characters reached to 93.329%, which basically summarized all 8 characters main information.

在相关分析基础上进行因子分析，结果表明，8个性状分别载荷在5个主因子上，第一主因子为果实综合因子，包括单果重、果肉厚度、可食率和可溶性固形物含量；第二至五主因子分别为反映果实质地、成熟期、果核重、风味的因子，这5个主因子对8个性状的累计方差贡献率达到93.329%，基本概括了全体8个性状的主要信息。
