粗糙法

A two-dimentional isothermal transient full film and part film EHL model has been established, which is used to analyze lubricational behavior of cam-tappet pair of valve train. Using mulit-gird method, the oil film status during intake duration could be investigated with the consideration of dynamic effect. The influences of surface roughness are also taking into account in the part film model.

Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.

结果：倒置显微镜和透射电镜观察显示，经SAHA处理的细胞增殖速度显著减慢，细胞体积增大，细胞核较小，形状较为规则，核仁数量减少、体积变小，核内常染色质增多而异染色质减少，核质比例减小，细胞质内线粒体数量增多、线粒体嵴发达，高尔基体较为典型，粗糙型内质网增多，呈现出与正常上皮细胞相似的形态变化；MTT比色法测定结果显示不同浓度(2.5、5.0、7.5、10.0uM)SAHA对SMMC-7721细胞的增殖均有抑制作用，并有明显的剂量依赖和时间依赖关系；免疫细胞化学检测显示SAHA能显著降低PCNA和AFP在SMMC-7721细胞中的表达；流式细胞仪检测结果显示，SMMC-7721细胞经SAHA处理后，G0/G1期细胞明显增加，S期细胞则明显减少，细胞被阻滞于G0/G1期；RT-PCR检测结果表明，SAHA作用12h后SMMC-7721细胞中p21WAF1 mRNA的表达即有增加，24h后更为明显。

Rubbing: to rub two pearl,you can hear the sound of "sa sa" whenthe two real pearl scratching. Because true pearl it's made of thousands of pearl layers,so it's surface is coarse, not very smooth. But artificial pearl surface are pinked by dope. So it surface feel very smooth.

摩擦法--把两料珠子互相磨擦，人造珍珠因表层是涂料，故十分光滑；而南珠因其表层是一点一点的由珠贝分泌的珍珠质成百上千层地裹成的，实际上在显微镜下，珍珠表层是粗糙不平故有一种&涩&的感觉，有一种&沙沙&声。
