固定样本

We discuss asymptotically best linear unbiased estimators of the Logistic population based on selected order statistics and give the formula of computing the ABLUE, the variance and the covariance of the ABLUE in limit, and properties of the ABLUE, and so on. We give the optimum chosen of spacing which is the ABLUE with maximum asymptotic relative efficiency based on complete sample when selected order statistics number is less than 10, and obtain its maximum asymptotic relative efficiency.

讨论基于Logistic总体Ⅱ型截尾样本的若干个样本分位数的总体分布参数的近似最佳线性无偏估计；给出了该近似最佳线性无偏估计的计算公式，估计方差与协方差的极限表达式及估计量的大样本性质等；给出了全样本，样本分位点个数固定，但不超过10情形下，使上述近似最佳线性无偏估计有最大相对联合估计效率时，样本分位数选取法及最大相对联合估计效率；为大样本情形下，该近似最佳线性无偏估计的应用提供了理论依据。

Researchers who analyze this data set should be attentive to the issue of biased sample and think about the methods to correct the bias before drawing conclusions or making inferences.

综合样本流失与访问效应的检视，整体而言，TEDS固定样本的成功样本是偏差样本，在使用时必须加以注意或处理。

Dependent on the past research in seaice, in Bohai Sea, in 2003-2004 winter and 2004-2005 winter with level ice for the target we open the field experiments to study the essential spectrum characteristic of ice, removing by testing means various nonessential factor for sea water in the fixing big ice plate, building up 170 growth conditions to look like under the natural condition, the growth expect different sample series; in 2004-2005 winter and 2005-2006 winter continue two pass to break thorough Bohai Sea in the ship to collect 59 sea ice sample that have the non-essential ice factors in winter, open the influence research that the field hangs sand to contribute to the spectrum of the ice body; in 2005-2006 winter, fast ice to open the field spectrum curves to coast and analytical research.

总结前人的研究成果和开展一系列的室内实验，在渤海—北半球纬度最低的结冰海域，于2003/2004、2004/2005 连续两个冬季以单层平整冰为目标开展实验研究一年生海冰的冰体本质光谱特征，在固定冰盘上以实验手段摒除各种光谱干扰因素，在自然条件下建立170 个生长条件近似、生长期不同的样本系列；于 2004/2005、2005/2006 连续两个冬季通过破冰船深入渤海采集59 个具有非冰体本质因素的海冰样本，开展悬沙对冰体反射光谱的影响研究；于2005/2006 冬季，针对沿岸固定冰开展光谱测量和分析研究。

The fourth chapter arises the problem of aging of sample aiming at the applied fixed sample survey.

第四章，针对采用的固定样本调查方法，提出样本老化问题，并由此引出关于样本轮换问题的简单探讨，提出样本轮换主要遵循的原则。

After a long course of development, we feel that the development of IMI index has been relatively mature, with fixed sample group measurement, and online surveys, and other more mature way, so we think through the first half of the 08 media network Monitoring data can draw the following conclusions and found

在经历了一个漫长的发展历程之后，我们觉得IMI指数的发展已经相对较为成熟了，有了固定样本组测量，以及网上调查等比较成熟的方法，所以，我们认为通过对08年上半年网络媒介监测数据可以得出以下结论和发现

Therefore, the three TEDS surveys could be treated as a quasi-experiment. While the panel samples is treatment group, the independent samples is control group, and the interview is the treatment.

因此，这三次TEDS调查可视为一个大型的准实验设计：固定样本是实验组，独立样本是对照组，刺激变项则是受访经验。

TEDS conducted two waves of panel studies. These panel data can be used to describe the dynamics of Taiwanese voters and to develop related causal models.

台湾选举与民主化调查」执行了两次固定样本连续访谈，提供了非常珍贵的资料来进行台湾选民变迁的动态描述与因果模型的建立。

Both TEDS 2003 and 2004P were composed of panel samples and independent samples. Panel samples are those respondents who were interviewed in TEDS 2001 and independent samples are those respondents who were never interviewed before.

TEDS 2003与2004P调查的成功样本分为固定样本与独立样本两类，其中固定样本是再次访问TEDS 2001的成功样本，而独立样本则是该次访问另行独立抽出的受访者。

Methods: Twenty-four wooden sticks of the chestnut were divided into four groups randomly. Every stick was cut transversely in the median and a twelve-hole dynamic compression plate was attached by screws. Three sensor gauges were installed on each plate to evaluate strain.

用二十四根栗木(chestnut/castaneamolliss)条，样本随机分成四组，每组六条，每根栗木条模拟横断骨折，一块十二孔的动力加压钢板对称性固定，固定位置：A 组固定1-2-6；B 组固定1-3-6；C 组固定1-4-6；D组固定1-5-6。

Thirty wooden sticks of the chestnut were divided into five groups randomly. Every stick was cut transversely in the median and a twelve-hole dynamic compression plate was attached by screws. Three sensor gauges were installed on each plate to evaluate strain.

用三十根栗木(chestnut／castaneamolliss)条，样本随机分为五组，每组六条，每根栗木条模拟横断骨折，一块十二孔的动力加压钢板对称性固定，固定位置：A组固定1—6，B组固定1—2—6，C组固定1—2—3—6，D组固定1—2—3—4—6，E组固定1—2—3—4—5—6。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
