抽样

There are certain rules for sampling, right?

抽样有一定的规则，是吗？

For second algorithm SatTest2, searching and sampling are in the whole space of assignments. Hence it can find the satisfiable solution. Even no satisfiable solutions can be found, it is still to test the satisfiability of SAT problem with high probability. This is an important improvement of the conventional randomized algorithms.

第二个算法SatTest2则是在整个赋值空间中进行搜索和抽样，因此可以搜索到可满足解，即使搜索不到可满足解时，也能以高概率做出正确的判断，这是对传统随机算法的重要改进。

Quantification Research is adopted through a self-arranging "studies frustration questionnaire of schoolchild in primary school".

本研究采量化研究法，透过自编之「国小学童学业挫折因应量表」，以桃园县国小九十七学年度第一学期在籍之四、六年级学童为抽样对象。

Finaly, the reliability of static ice force for different reccurrence periods is calculated by taking Schwarz formula as formula of calculating static ice force and results are simulated by Monte Carlo important sampling method.

最后，以Schwarz公式为静冰力计算公式，结合得到的冰厚和冰强度的概率分布，采用映射变换法进行不同重现期静冰力的可靠度分析计算，并用蒙特卡罗重点抽样法进行模拟。

If these human inputs are assisted by special quality-control instruments machines and scientific sampling proceduresso much the better.

如果这些人力的投资再加上质量控制设备和科学抽样的辅助就更好了。

EMBU and the self-ordained family environment questionnaire were used. 420 students were tested and inquired.

By using holographic theory,hologram sampling theorem and separation condition of frequency spectrum,the maximum spatial frequency of off-axis Fresnel was analyzed,and recording conditions were studied.

根据全息理论，通过分析全息图光栅结构的极值频率，利用抽样定理以及频谱分离条件，分析了离轴菲涅耳全息的记录条件，得到了不同于以往文献的最小记录距离及参考光源设置表达式，并做了计算机模拟验证。

Therefore, the sequential analysis which may stop early will be concerned by us.

因此，可减少抽样成本的逐样分析成为我们关心的对象。

In terms of time series analysis, sequential data forecast method based on resampling and data cleaning algorithm based on regression diagnosis are designed. The algorithm improves the acuracy of prediction.

在时间序列分析方面，设计了基于样本数据重抽样的时序数据预报方法以及基于回归诊断的数据清理算法，有效提高了时序数据的预报精度。
