Lines are induced on the surface of a photosensitive glass by focused femtosecond laser transverse writing with scanning velocity in a wide range of 40-1800 μm/s. The formed lines are analyzed using scanning electron microscope and optical microscope.

利用聚焦飞秒激光的横向直写方式，采用宽的扫描速度范围(40-1800 μm/s)，在光敏玻璃表面上诱导了直线结构，并扫描电子显微镜和光学显微镜分析了形成的直线，发现随着扫描速度不同，形成的直线具有三种不同的形貌。

To investigate the effect of p38MAPK signal conducting pathway on livercancinoma cell's malignant phenotype induced by VEGF,we take theexperiment with cell growth test,scanning microscope and laser scanningconfocal microscope so that observe effect of p38MAPK signal conductingpathway on liver cancinoma cell growth,pseudopodium formation andframework of cytoskeleton induced by VEGF.results indicate that the cellbecame ellipse and there were more and thick pseudopodium in the cell'ssurface after being treated by VEGF,and destroyed framework ofcytoskeleton,which can be blocked by pretreated with a special inhibitor ofp38MAPK SB203580 so that VEGF promote metastasis by enhancing livercell migration and movement via p38MAPK signal conducting pathway,butVEGF promote cell growth without p38MAPK signal conducting pathway.

为进一步探讨VEGF通过p38信号传导通路诱导肝癌细胞转移时，对肝癌细胞恶性表型的影响，采用细胞增殖实验、扫描电子显微镜、激光扫描共聚焦显微镜观察VEGF对肝癌细胞增殖作用、细胞伪足形成、细胞骨架微丝结构的影响以及p38MAPK信号通路调控作用。结果显示，VEGF能够不通过p38信号通路促进肝癌细胞增殖；VEGF诱导肝癌细胞丝状伪足增多、增长，使细胞骨架微丝结构破坏、甚至消失。阻断p38MAPK信号通路，可以抑制VEGF诱导的肝癌细胞伪足形成，细胞骨架丝状结构呈束状，排列较规整。上述结果表明，VEGF可以通过p38信号传导通路诱导肝癌细胞伪足增多、增长，促使细胞骨架微丝结构破坏，使肝癌细胞迁移、运动能力增加，促进肿瘤转移。VEGF并不通过p38信号通路诱导肝癌细胞增殖作用。

Methods8 species of its fruit were observed under light microscope and scanning electron microscope, and most of them were examined for the first time.resultsthe shapes of fruit are usually different from each other;there are obvious differences in color;the types of ornamentation of fruit coat are mainly similar to ruga and washboard.

The microstructure and properties of high manganese steel under the conditions of different rolling load were analyzed and studied through the OM,TEM and HD-187.5 sclerometer.

利用光学显微镜、透射电子显微镜和HD-187.5型硬度计对高锰钢在不同轧制应力条件下的组织和性能进行了分析和研究。

Leaf epidermis of 35 species of Ormosia in China was examined under light microscope andscanning electron microscope. The epidermal cells of both upper and lower leaf surfaces are polygonal or irregular in shape, anticlinal walls are straight, arched, sinuolate or sinuate, and stomata are elliptic or ovate.

用光学显微镜和扫描电子显微镜观察了红豆属35种的叶表皮形态，这些植物的叶上下表皮细胞为不规则形或多边形，垂周壁有平直、弓形、浅波状或深波状，表皮细胞形状和垂周壁在种间有一些差异。

During the 1940's, electron microscopes routinely achieved resolution better than that possible with a visible light microscope

在40年代，电子显微镜毫无例外地比可见光显微镜获得了更好的分辨能力。

The pollen of approximately 400 species was observed by optical microscopy. In the meantime, the pollen of Punicaceae and Aceraceae was studied by scaning electron microscopy.

在对研究区近400种植物的花粉进行光学显微镜观察研究的同时，还用电子显微镜对收集比较集中的石榴科及槭树科的花粉进行了系统的研究。

Methods: Optics and electron microscope were used to observe the microstructure and ultrastructure of human apocrine sweat glands in axillae from 20 osmidrosis patients, and then discuss the relations between different gender, age, seasons arid odor intensity.

用光学显微镜、透射电子显微镜观察20例腋臭患者腋窝顶泌汗腺显微、超微结构，并分析性别、年龄、季节等发病因素与气味强度之间的关系。

The conidia formation was inhibited on the PDA agar plate with the culture filtrates though the spores germinated and formed their hypha in certain degree. Growth suppression, increasing branches of their offset and swelling in the middle and/or the top of the hyphae were observed with microscope and scanning election microscope. The longer time the treatment, the more severe the hyphae aberration was, some of them were altered as beadlike, some offsets formed cluster-like structure.
