When investors are in the treasury secondary market, they have to undertake two kinds of risks: the first one is yield risk, that is, return of investment is lower than inflation rate. This risk can be depicted as the deviation between the ROI and the inflation rate. Secondly, fluctuation risk in the treasury secondary market, that is, the uncertain fluctuation risk may be bullish or bearish in the treasury market.This risk can be depicted as the square deviation of the treasury price in the secondary market.

在国债现货二级市场上的投资者，要承担的风险主要有两种：第一种风险是收益率风险，也就是投资收益率可能低于通货膨胀率的风险，这种风险可以用与通货膨胀率相比较的差值的大小来描述；第二种风险是二级市场价格波动性风险，也就是市场价格上、下波动的不确定性风险，这种风险可以用二级市场价格的标准差来描述。

In this paper,using numerical solution method of vector diffraction theory,we discuss the dependence of reflectivity upon structural parameters of subwavelength grating,particularly upon substrate thickness.It can be used as the basis for design and fabrication of binary optical element with proper antireflection property.

文摘：利用矢量衍射理论的数值求解方法，研究了亚波长光栅结构参数对反射率的影响，特别是基底厚度对反射率的影响，这些为设计和制作具有优良的抗反射性能的二元光学元件提供了设计依据。

By use of bipartition, the entropy of each wavelet block approximates to the target bit rate of one. 5. An efficient algorithm is presented for constructing quantization tables of wavelet blocks with optimal bit allocations for a given image. The algorithm uses wavelet coefficient distribution statistics in a novel way, and pays attention to the traits of HVS.

该算法首先根据每个小波块所含能量的多少和到每个小波块实际编码所用的比特数，给其分配不同的码率；然后根据二分法，通过调整各小波块的量化因子使得各小波块的熵逼近它的目标比特率。
