Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.

结果：随着药物浓度的增加和作用时间的延长，蒿甲醚对胃癌SGC-7901细胞的抑制作用呈时间和浓度依赖关系：在倒置显微镜、荧光显微镜、扫描电镜和透射电镜下可观察到典型的凋亡细胞的形态改变，表现为：核固缩或染色质边聚或凝聚成大块状，可见凋亡小体，线粒体肿胀增殖，严重的空泡化，随作用时间的延长，细胞增殖速度减慢，细胞体积缩小变形；流式细胞术显示胃癌SGC-7901细胞出现明显的凋亡峰，随着作用时间的延长，其凋亡率逐渐升高，细胞周期阻滞在G_0/G_1期，S及G_2/M期细胞数大量减少；流式细胞术TUNEL检测结果显示细胞凋亡和坏死同时存在。

The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected.

研究表明，小世界网络模型模拟的集群网络具有集群形成期网络整体密集性和连通性剧烈变化的特征，而个体选择价值函数模型可以解释集群网络的成长期、成熟期的密集性和连通性趋于稳定的特征，将2种演化规则相结合，则可以反映集群网络从形成期到成熟期的各生命周期特征。

The Auger depth-profiling analysis of the samples shows a periodic structure with little interdiffusion at the interfaces.

The results showed that with the increasing of repetition frequencies, power density, and pulse width of laser beam and with the decreasing of scanning speed, the kerf quality could be improved. Besides, a formula of estimating the kerf surface roughness was also presented, which can explain the experiment results well.

在加工电子行业中表面组装用的模板时，一般采用化学刻蚀法，其缺点是加工精度低、工序多、周期长，特别是受刻蚀因子的限制，模板的最小缝隙宽度不能低于模板厚度的 1 2 ，因而难以满足日益发展的微电子技术对电子线路制作精度的要求。
