In order to improve anti-corrosion and anti-oxidation properties of Q235 steel,the processes of chro maluminizing were studied based upon the results of chromizing and aluminizing of this steel.

为提高Q235钢的耐氧化性和耐蚀性，进行了渗铬和渗铝，在此基础上进行了铬铝共渗。

The cell cycle and apoptosis and the expression of P-pg, bcl-2, P53 in the MG63 and MG63/R cell lines were analyzed by flow cytometry. Results The resistance index of the MG63/R cells to cisplatin was 83.557±4.841. The cells also had resistance to doxorubicin, vincristin, methotrexate and cyclophosphamide. Disordered structure of the MG63/R cells was observed through microscopy. The cells appeared in triangle, polygon and polynucleation. The increase of granular endoplasmic reticulums and apophyses was observed through transmission electron microscopy. The proliferation ability of MG63/R increased significantly, with a low apoptosis index.

结果 经顺铂186d的诱导，建立了MG63/R，其对顺铂的耐药指数为83.557±4.841，对阿霉素、长春新碱、氨甲基蝶吟、环磷酰氨亦产生不同程度的交叉耐药；光镜观察可见MG63/R细胞排列不规则，形态呈三角形、多角形及多核现象；透射电镜显示MG63/R细胞表面突起增加，粗面内质网丰富；细胞周期分析显示细胞增殖能力明显增加而细胞凋亡明显降低；MG63/R细胞 P-pg、bcl-2阳性表达较MG63细胞明显增加，P53表达则明显降低。

Compared with asphalts,the tensile strength and the fracture elongation rate of the coating obtained increase 10～15 times respectively, and the coating has advatages such as light weight,seamless,easy to maintain and to apply.

这种防水涂料的拉伸强度比沥青的提高了 5～ 10倍，断裂伸长率比沥青的提高了 5～ 15倍，并且具有良好的耐酸碱、耐候和防水性能，涂层轻、无接缝、易修补和施工方便

Textile colorfastness to crocking is very important, and there are differences among test methods in different countries. The test results are influenced by different test methods. In order to avoid the "trade rubs" among different countries, it is necessary to know the correlation among test results of different test methods. In this paper, Chinese GB(GB/T 3920-51997), AATCC(AATCC TM 82004) and JIS(JIS L 0849-1996) test methods of colorfastness to crocking were introduced.

纺织品耐摩擦色牢度是重要的检测指标，各国的标准和测试方法有一些差异，而不同的测试方法对测试结果有一定的影响，为了解不同测试方法测试结果的相关性，以避免贸易摩擦，本文介绍了耐摩擦色牢度的我国国标(GB/T 3920 5 1997)、美国纺织化学家及染色家协会标准(AATCC TM8 2004)、日本标准工业协会标准(JIS L 0849 1996)等三个测试方法标准，通过对相同试样的三种测试方法的测试，探讨了评定值之间的相互关系。
