A suspected new virus in ailanthus mosaic and/or ringspots samples was foundserologically close related to WMV.

对表现花叶和环斑症状的臭椿样本进行病毒检测，发现与WMV抗血清呈阳性反应的样本高达95%。

Real AdaBoost algorithm demands division of the sample space. The traditional finite division can not reflect the distribution of positive and negative samples.

连续AdaBoost算法要求对样本空间进行划分，传统的等距划分无法体现正负样本各自的分布规律。

The representative points of positive case support vectors and negative case support vectors in sample set are defined, the measure and eigenfunction between sample x and y allusiveness from initial space to eigen space under a kernel function k are researched, and a correlative theorem with demonstration is given.

定义了样本集中的正例支持向量和反例支持向量的代表点，研究了原始空间样本x，y在核函数k映射下在特征空间中的x，y映象之间的度量和特征函数并给出了相关的定理及证明。

Procedure— Using a dry syringe, quickly inject the Test Preparation, accurately measured and estimated to contain 0.5 to 5 mg of water, or as recommended by the instrument manufacturer into the anolyte, mix, and perform the coulometric titration to the electrometric endpoint. Read the water content of the Test Preparation directly from the instrument's display, and calculate the percentage that is present in the substance.

规程---使用一个干燥的注射器，快速注入测试样本，准确测量并估计大约含有0.5~5mg水，或者按照仪器制造商的推荐至阳极液中，混匀，采用库仑滴定法滴定至电量终点，直接从仪器显示处读取测试样本的水的含量，计算样品中存在的水的百分含量。

In the case of frit A, the results have shown that it remains amorphous until 800 8C and only after that it starts to form anorthite and diopside.

样本A的无组织状态直到温度达到800.8摄氏度才被破坏。之后该样本中开始出现钙长石和透辉石。

The Facility houses over 25,000 meters of deep-sea geological core samples recovered primarily from the Southern Ocean and the Antarctic continent.

网站的数据库包括190864种样本，用户可采用全文样本检索、全文中心检索和绘图的中心检索等三种方式查询数据库。

Traditional statistics is mainly conducts the research to the sample number approach in the infinity time evolution theory, but counts the theory of learning is conducts the research to under the small sample condition theory of learning.

传统统计学主要是对样本数目趋近于无穷大时的渐进理论进行研究，而统计学习理论则是对小样本条件下的学习理论进行研究的。

Some small sam-ple and large sample superiority of this estimate such as the unbiasedness,convergence,asymptotic normality and the property of simulation,are obtained.

我们得到分块拟回归的小样本和大样本性质，如无偏性、均方收敛性、强收敛性和渐近正态性，并讨论了曲线拟合的性质。

This dissertation is concerned with some problems regarding the asymptotic property of nearest-neighbor density estimator for α—mixing and nagetive quadrant dependent samples. The results extend the corresponding theorems in i.i.d.

本文主要考虑了最近邻密度估计在α—混合序列和两两NQD混合序列情形下的大样本性质，推广了独立同分布和其它相依情形下最近邻密度估计的大样本性质，如相合性、渐近正态性等。

Describes general methods of point and interval parameter estimation and the small and large sample properties of estimators: method of moments, maximum likelihood, unbiased estimation, Rao-Blackwell and Lehmann-Scheffe theorems, information inequality, asymptotic relative efficiency of estimators.

点估计和区间估计的一般方法，估计量的小样本和大样本性质：矩法，极大似然估计，无偏估计，Rao-Blackwell 和 Lehmann-Scheffe 理论，信息不等式，渐进相对有效估计量。
