提出了二次彩虹法测量高折射率玻璃微珠折射率的新方法，理论上分别用几何光学和衍射光学的方法分析了一次彩虹法和二次彩虹法测量玻璃微珠折射率的原理，给出了相应的数值结果，比较了两种测量方法各自的特点。

The third aspect: we consider comparison of Minimum Norm Quadratic Unbiased Estimator and ordinary least squares estimator of in the multivariate normal linear model Y ~ N{XB, V, where the design matrix A' need not have full rank and the dispersion matrix V can be singular.

使用的损失函数有二次损失函数、嫡损失函数和对称损失函数。论文基于以下三个准则：二次损失风险准则、嫡损失风险准则和对称损失风险准则，将MINQUE和LSE进行比较。

Field data of pedestrian flow was collected in Chinese comprehensive passenger transport terminal—Xizhimen underground station using video recording, and then selected and analyzed by statistic analysis software SPSS. Parameters relation models for pedestrian flow on different terminal facilities were established based on data statistics. The results show that the pedestrian flow-density relation model is quadratic equation in corridor; the flow-space relation model is quadratic equation when space is below a certain value and is logarithmic equation when space is above the value; the speed-density relation model is linear equation. The models on stairs show the similar characteristics, but the eigenvalue is different.

对国内综合交通客运枢纽——北京西直门地铁站行人流数据进行视频采集，采用统计分析软件SPSS对行人流参数数据进行筛选及拟合分析，建立了不同设施的行人流参数关系曲线及函数模型，研究结果表明，水平通道处行人流量与密度呈二次函数关系、流量与空间在某一临界点两侧分别呈二次函数及对数函数关系、速度与密度呈线性关系，楼梯处与之相似但特征点数值存在差异。

In addition, larger temperature difference of heat transfer can enlarge the maldistribution of the temperature.

通过比较二次封头和普通封头换热器截面温度分布情况发现：二次封头结构明显地改善了换热器出口截面温度分布，尤其在大Re下，温度分布不均匀性的改善效果更加显著，同时换热效能可增加7%左右。

In this paper,the effect of the angle of the nozzle sub-hole has been studied.
