The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.

结果表明，无风稳态热晕效应存在时，随发射功率的增大，一定传输距离截面上的峰值功率密度先增人后减小；截面上的峰值光强随基模高斯光束的腰斑半径的增大而增大；随着传输距离的增大，截面上峰值光强在逐渐减小，能量在逐渐向周围扩展；在一定条件下，截面上的光强分布会呈现中心光强小于周围光强的&草帽型&分布。

Numbers near the branches were bootstrap probability values coming from 1000 replications. Some bootstrap probability values were 92%(Coturnix chinensis/ Coturnix japonica), 100%(Tetraogallus altaicus/ Tetraogallus himalayensis), and 100%(Tetraogallus altaicus/ Tetraogallus himalayensis/ Tetraogallus tibetanus. The overall average distance was 0.112, and average genetic distance among Tetralgallus was 0.042. The genera Alectoris, Coturnix, Tetrao-gallus and Pucrasia formed a monophyletic group.

Based on thecluster analysis and PCA,the 23 germplasm materials investigated may be divided intotwo groups,most of genetic variation was within group.There was a certain relationshipbetween genetic distance and geographic distance among Arrhenatherum elatius L. in theresearch.

基于ISSR标记的UPGMA聚类分析与主成分分析表明，23份高燕麦草种质材料能按照采集地点的不同分为两大组，组间遗传距离的差异是导致供试材料整体遗传差异较大的主要因素，而组内材料间亲缘关系较近，地理距离与高燕麦草的遗传距离有一定关系。

Atmospherical plasma jet carries to the surface modification of tungsten oxide nanorod. The results showed that the modified use of plasma gas (O2), in the same distance to increase deal with test-chip of the surface then there is the formation of small particles with the trend, and in the higher distance to some deal with test-chip of the trend of the formation of small particles lower. N2 was more significant than that of Ar plasma for surface modification, and the test piece is somewhat part of the surface nano-rods box integration with the formation of small particle side of the box there is scheduling a clear rod-like.

本研究应用常压低温电浆设备对氧化钨奈米棒进行表面处理，其改质结果显示使用电浆气（O2）下，在一样的高度距离下随了处理次数的增多，试片表面随之融合一起有形成小颗粒的趋势，且在一样的次数下随了距离高度越高其形成小颗粒的趋势越低；在使用电浆气体为N2与Ar下，电浆气体N2比Ar有较大幅度的电浆表面处理，且试片表面有些许部分奈米棒融合一起形成小方块颗粒其方块颗粒侧边有明显的棒状排立。

Through introducing the C155 Occupational Safetly and Health Convention and meanwhile by analyzing the current situation of law designed for protecting peasant workers rights. Therefore the distance between national laws and convention is revealed by the comparition. To these existed distance, we may bring into our country the experience of developed countries who advanced at the protecting the labor' rights under the convention, meanwhile good and advisable suggestions and advices shall be offered.

本文通过介绍《职业安全和卫生及工作环境公约》，以及分析当下我国农民工群体在职业安全、职业卫生、工作环境方面的现状、法律成因等，通过对比找出目前我国对农民工在这些方面的立法与公约有多大的差距；同时，结合其他发达国家在该公约框架下如何保护工人权益的经验对我国重新构建农民工劳动权益保障机制提出一些建议和意见。

In this paper, a new conflict coefficient is presented. First, the deficiency of the classical conflictive coefficient is analyzed. Then, the distance function between evidences is introduced. A new model to represent conflict is constructed with the distance function and the classical conflictive coefficient. Finally, numerical examples verify the efficiency of the proposed method.

针对这一问题，首先分析了证据理论中经典冲突系数的不足，引入证据距离函数表示证据之间的差异性，结合经典冲突系数一起提出了一种新的证据冲突表示方法，克服了经典证据理论冲突系数的不足，能更有效地度量证据的冲突程度，最后通过算例验证了该方法的有效性。

This method is that we first threshold image from the image, then we apply fuzzy distance transform to get fuzzy distance image, and finally, we use the watershed algorithm to apart conglutinant or overlapped grain.

该方法首先对颗粒图像进行二值化，然后对图像作模糊距离变换得到模糊距离图，再利用分水岭算法将粘连或者部分重叠颗粒分离。

The evaluation method and algorithm of shape error (roundness, plane straightness, space straightness, cylindricity) were discussed. A new kind of algorithm, namely mesh searching method, which can be used to evaluate the roundness error, plane straightness error, space straightness error and cylindricity error, were put forward. With this algorithm, the shape error can be obtained by transferring the distance formula repeatedly and simple judgment without linearzing the distance formula (from point to point or point to line) and choosing optimal direction and step length.

对形状误差(圆度、平面直线度、空间直线度、圆柱度)的评定方法及算法进行了讨论，提出了一种评价圆度误差、平面直线度误差、空间直线度误差及圆柱度误差的新算法——网格搜索法，该算法不需要对距离公式线性化，也不需要选定优化方向和优化步长，只需重复调用距离公式和简单的判断即可得到符合定义的形状误差。

Results: Of the slight keratoconus group: the above indexes significantly decreased(P＜0.05). Of the moderate group: the above indexes, except for the apex decentration distance significantly decreased at 12 months and more evidently at 18 months.
