A method for identifying the damage, using the influence line curvature of deflection differential values at a point before and after the damage is proposed, that is, when the moving load is in the area without the damage, the influence line curvature is zero, however when the moving load is in the area with the damage, the influence line curvature evidently increases and has the relationship with the positions of the damage points and the rigidity of the beam before and after the damage.

提出利用损伤前、后某一点的挠度差值影响线曲率来识别损伤的方法，即当移动荷载位于无损区域时，挠度差值影响线曲率为0，当移动荷载位于有损区域时，挠度差值影响线曲率明显增大，且与损伤点的位置、损伤前后的刚度有关。

According to the projection space, line and plane can be divided into upward-traveling and downward-traveling. The concepts of near axial-terminal and far axial-terminal to the straight line projection is introduced. The rule of the visibility of line and plane intersection is deduced.

将直线和平面按其在投影空间的位置，分为上行和下行两类，对直线的投影引入近轴端和远轴端的概念，有助于对线面相交空间位置的理解，而且使直线与平面相交可见性的规律更加清晰和直观。

方法应用放免法检测人高转移大细胞肺癌原代细胞株L9981，转基因细胞株L9981-nm23-H1和空载体转染细胞株L9981-pLXSN的PKA的活性，应用MTT法检测L9981，L9981-nm23-H1和L9981-pLXSN细胞株的体外增殖，改良的Boyden小实法检测L9981，L9981-pLXSN，L9981-nm23-H1这3个细胞株细胞体外侵袭力。

A more reasonable approach is to use a line printer, which, as the name implies, prints line by line instead of character by character.

比较合理的方案是采用行式打印机输出。

But all of the color line, such as the line spacing DataGird color, will not be seen, it is because out of the backgroundColor is the same color and line of the above.

但是所有的行的颜色，比如DataGird的行的间隔颜色，将不会被看到，这是因为列的backgroundColor是一致的并且在行的颜色的上面。

The results show that this process is mainly triggered by the upper and lower shear line and the humidity mutation line on the ground is the indication of the squall line formation and development.

结果表明：中低空切变线是此次强对流天气的触发系统，地面湿度突变线对飑线的生成及发展具有指示意义。

According to short term monitoring data, it appears that the new cell echo before the radar echo is advantage for the development and maintenance of the squall line. And the initialization of new cell is associated with boundary-layer convergence line. As a result, mesonet data is useful fur to research on squall line.

从短时监测的资料分析，飑线发展过程中，雷达主回波前方的新生的回波单体对飑线发展和持续十分有利，而它的新生与边界层的辐合线相联系，因此，充分利用中尺度地面观测资料有助于飑线的发展研究。

The results indicate that the squall line systems are stronger with the increasing of water vapor in the lowest kilometer of atmosphere. The decreasing of water vapor in the height of 3 to 5 kilometer lead to a weaker development of squall line system. The decreasing of water vapor above 5 kilometer level has less impact on the development of the squall line system.

根据 Lin and Arakawa( 1997a，b )的研究指出，积云内部空气逸入源主要来自云顶发展高度以下的区域，且可能来自各种不同的环境高度，因此环境水气的垂直分布情形对积云结构的发展有重要影响。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
