This data not noly suggest that polymerization-depolymerization is important to stomatal movement and stability, but also interpret conflicting results whether actin polymerization or depolymerization in stmatal guard cell.

这不仅提出了肌动蛋白解聚—聚合在气孔开关运动和稳定性中的重要作用，而且可以解释保卫细胞中肌动蛋白是处于解聚状态还是聚合状态的不同报道。

The result showed that the changes of stoma density ranged from 91~173 unitmm^(-2). Guard cell length ranged from 25.8~32.4 μm. Guard cell width ranged from 18.4~24.2μm. Guard cell width in sports variety was longer than in original variety.

结果表明：叶片气孔密度的变化范围在91~173个／平方公厘，保卫细胞长度变化在25.8~32.4μm之间；保卫细胞宽度变化在18.4~24.2μm之间，芽变品种的保卫细胞的宽度有变长的趋势。

So we carried out the study on the actin dynamics in the process of stomatal movement by using pharmacological experiments and confocal laser scanning microscopy in the guard cell of Vicia faba.

本文以蚕豆下表皮为材料，利用药理学及激光共聚焦扫描显微技术，对气孔运动过程中肌动蛋白的动态变化进行了研究。

When stomatal closure, K +,Cl - contents decreased obviously in vacuole and cytoplasm, but increased in cell wall of guard cells.

伴随着气孔关闭，保卫细胞液泡和细胞质中的K^ 、Cl^-含量都明显下降，而细胞壁中的K^ 、Cl^-含量增加。

This is a view of the air holes from outside.

这是从外面看到的气孔。

The generation materials of the reservoirs in Luo151 igneous oil pools consist of Intergranular micropore hornfels, condensate blowhole-solution void diabase condensate edge, the edge and center of the condensate seam diabase, of which are divided into horizontal, vertical and reticulated cracks according fracture occurrence.

研究区火成岩油藏储集层成因类型可分为晶间微孔隙角岩、冷凝气孔-溶蚀孔辉绿岩冷凝边、冷凝缝辉绿岩体边缘及中心带，其中冷凝缝辉绿岩带根据裂缝产状可以进一步分为水平、垂直和网状裂缝等类型。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。
