At first,the negative data is divided into several parts accumulatively according to the geometric distribution of the training data.

该方法首先根据样本的几何分布，用迭代的方式把负样本分成若干部分与正样本线性可分的样本；然后用L-SVM对这些正负样本进行分类，得到若干个线性分类器；最后，将这些线性分类器顺次组合，构成级联分类器。

That the strategy needing to pay attention to whose product mix especially first is adjusted, makes structure complicated , the high accuracy top grade mould gets quicker development in the mould industry development on the days to come.

模具行业在今后的发展中，首先要更加注意其产品结构的战略性调整，使结构复杂、精密度高的高档模具得到更快的发展。

Carry on structure analysis to the spare parts first, understand its structure characteristics to choose suitable semi-finished product and the semi-finished product manufacturing of the reasonable a craft thus;Then the technique request of spare parts carries on analysis, understanding it each process superficial accuracy grade and the surface rough degree, make it process the fixed position in the process and clip a tight way in assurance inside the scope of economic accuracy, draw up the machine of spare parts to process craft process thus and further, choose each work preface to process equipments and craft material, the assurance slices to pare dosage and craft size, computing the man-hour of each work preface settle sum.

首先对零件进行结构分析，了解其结构特点从而选择合适的毛坯以及合理的毛坯制造工艺；再零件的技术要求进行分析，了解其各加工表面的精度等级以及表面粗糙度，使其在经济精度的范围内确定加工过程中的定位和夹紧方式，从而进一步拟订零件的机械加工工艺过程，选择各工序加工设备以及工艺装备，确定切削用量以及工艺尺寸，计算各工序的工时定额。

In the first part of the study, we focus on the accuracy of color measurement for standard testcharts.

本研究首先针对测试导表的色彩测量准确度进行研究。

First, it discusses the impact of the number of dimensions on rating results and the four meta-dimensions in AC. Second, it introduces the indexes of rating accuracy in AC and expounds different types of rater training programs and their impact on rating accuracy. Third, although AC has proved good criterion-related validity, the research on its construct validity has not yet reached an agreement.

首先，文章讨论了评分维度的数目对於评分结果的影响，以及评价中心中的4个元维度；其次，介绍了评价中心中衡量评分效果的指标，并讨论了评分者培训的分类及其对评分效果的影响；第三，虽然评价中心具有良好的效标关联效度，但对於其结构效度的研究至今尚无统一结论。

Its salt is transparent qualitative acerbity natrium discovers in eye vitreous body above all.

其盐透明质酸钠(sod ium hyaluronate，SH)首先在眼玻璃体中发现。

In chapter five, the acetic acid gas sensors were studied, which can be applied in heroin drug detection.
