Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .

如果保持偏转板的电压大小不变，改变加速极的电压，可以看到加速极的电压减小，则电子束偏转的角度反而增大，这是因为加速极电压低，则电子的水平方向速度变小，电子在偏转板中受电场力作用的时间加长，所以偏转的角度增大。

Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.

光镜下H-E染色切片中腺上皮区仅可以区分出四种类型的细胞：弱嗜碱性纤维样细胞、强嗜碱性纤维样细胞、嗜酸性颗粒分泌细胞和纤毛细胞等；腺上皮下的基底膜区有少量结缔组织存在；扫描电镜下可以观察到鳃下腺表面的纤毛及腺细胞的分泌物等情况；透射电镜下观察到腺上皮中有支持细胞、感觉细胞和7种类型的腺细胞；近基底膜区观察到富含粗面内质网的细胞；基底膜间为薄层疏松结缔组织，内含肌细胞及神经末梢等结构。

When electron accelerates, its charge quantity won't change, as a result, its electromagnetic mass is constant, and the electromagnetic mass won't satisfy Lorentz transformation,thus, there is obvious inconsonance if we treat electromagnetic mass as a part of the gravity mass ---- as long as we insist the idea that the charge quantity of any electron is a constant.

当电子加速运动的时候，其电量是不会改变，所以其电磁质量不会发生改变，电磁质量不满足Lorentz transformation，因此把电磁质量作为引力质量的一部分存在着不协调性——只要维持电子电荷值不变的观念，这个问题不管怎么也解释不通。

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。
