查询词典 representative sample

The main work of this thesis is simulation study on the basis of large sample properties for two estimates by Monte Carlo method with some models. We consider the problem of the choice of window width, consistent rate and some doubtful points about consistent rate with fixed sample size.

本文的主要工作是依据大样本性质，对特定模型的这两种估计用Monte Carlo方法进行了模拟试验，讨论了长度有限的样本情况下窗宽的选择问题，比较了两种估计的拟合程度，相合速度并提出了对相合速度的一些疑难点。

The calculation results are in good correspondence with the experimental results which were measured by fundamental wavelength scanning at fixed position of sample or at different rotation angle of the sample.

利用光学超晶格LN晶体，我们验证了准位相匹配过程中倍频转换效率与畴结构周期数的平方关系，获得了在500层畴结构下满足该平方关系的实验结果。

Map strip sampling has no length and width; it also doesn't require the fixed shape of sample. The method provided a convenient way to determine the region for survey and calculated the area of the strip sample, thus resolving problems with calculating the survey area in past work.

地图样带法没有长度和宽度概念，也没有规定样带的既定形状，提供了一种确定调查范围和计算样带面积的便捷方法，解决了过去调查中样带面积计算的难题。

Although the process for calculating the optimal fixed sample size is quite simple, it doesn't stop unless the last sample collected. So it has the property of the fixed overall cost.

最佳固定抽样个数法虽然计算简易，但无提早停止抽样的特性，即有固定成本性质。

Suggesting: once the sample has been used for the flash test, new sample should be taken for next flash test.

D Flexible LC notepaper:After a flexible PDCLC sample is irradiated with a suitable UV light for a suitable period at isotropic state, the CLC texture in whole sample is changed to scattered focal conic.

应用在软性基板的PDCLC元件在受到适当紫外光照射后可得一散射态之可挠式面板，若施加适当压力，可如触控笔般在元件上写入讯息或图像，该图像为反射结构。

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

当PDCLC照射紫外光的时间超过某一特定时间，则表面配向被聚合物薄膜破坏而达成散射态之穿透度最低状态，若持续照光聚合时，因仍然处於focal conic态，故穿透度不再改变，但单体聚合造成相变温度上升，直到单体全部聚合为止。

In fuzzy division of input space of the model, the division references consider not only the space distance of input sample data, but also the rule output error, thus defining"generalized sample distance", which makes model structure better.

在模型输入空间的模糊划分中，不单只考虑输入样本数据的"空间距离"，同时将规则输出误差作为输入空间划分的另一依据，由此定义"广义样本距离"，使模型结构更加合理。
