空泡形成

When form solid film, cavitate bladder blow up in ultrasonic power, bring thousands K high temperature in the thumbnail time and the thumbnail spare, go with strong bow wave and mirshoot flow, it can intensify the process of mass transfer, so reaction rate with ultrasonic wave have higher than without ultrasonic wave.

固态膜形成后，在超声波作用下空化泡崩溃，在极短时间内和极小空间中产生几千K的高温，伴生强烈的冲击波和微射流，强化传质过程，因此在超声波作用下磷矿的分解率比无超声作用时的分解率高。

During the wall thickening, the number of Golgi bodies increased apparently and cytoplasm was filled with Golgi vesicles. Polylamellate structure of the secondary wall appeard, Along with the further development of tracheary elements, the nucleous disappeared and organelles were decreased, while cortical microtubules were arranged neatly against the inner side of plasmalemma.

初生壁与质膜之间有间隔较规律的次生壁突起；中期，线粒体和高尔基体的数量明显增加，细胞质中几乎充满高尔基体及其囊泡，次生壁中微纤丝已成有序排列；晚期，细胞核消失，导管中央形成空腔，细胞器迅速减少，仅观察到少量高尔基体和线粒体，有大量周质微管沿细胞长轴分布，且在次生壁的周围有大量小泡附着，次生壁的分层结构清晰可见。

After the cells dealt with GS-Rh2 of 13.0 mg/L, the typical apoptosis cells were discovered: showing disorganized, highly contracted and vacuolated, condensed cytoplasm, vanished karyotheca, ruptured cell nucleus and apoptotic body.

凋亡细胞吉姆萨染色检测：经13.0 mg/L人参皂甙单体Rh2处理后，HL60细胞出现核染色质浓缩、呈周边凝聚，核膜裂解形成凋亡小体、胞质出现空泡但胞膜完整的典型细胞凋亡形态学改变。

After 72 h, MCF-7 cells which were treated by PE had become bigger and flatter meanwhile the appearance of vacuolization and particles which are the specific patterns of the cell senescence were also observed.

结果发现藻红蛋白作用 72 h 后，细胞呈现变大变扁平，细胞内形成空泡、颗粒增多等明显衰老形态。

Simultaneously the disappearance of microvilli, vacuolization of cytoplasm, dispersion of nucleus and appearance of apoptotic body were observed under transmission electron microscopy. All these morphological changes are hallmarks of apoptosis.

凋亡细胞经荧光染色后表现为细胞核固缩、碎裂；透射电镜下观察发现细胞微绒毛丧失，胞内出现空泡，胞核解体及形成凋亡小体等典型的凋亡特征。

It is one of the efficient approaches that the air-film is accreted on blade surface of operative marine propeller for improving cavitation characteristics.

在船用螺旋桨桨叶表面充气以形成气膜是改善其空泡特性的有效方法之一。

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization. The surface of the thrombosis existed red blood cell and librae.(2)Elatic fibrila staining: the internal elastic menbrane almost completely disappeared, the intact internal elastic menbran could be seen in the new small vessels.

动脉瘤管壁厚薄明显不均，全层或局部区域显著变薄向外膨出，内皮细胞空泡变性或坏死脱落，部分内皮细胞剥离并突入管腔成游离状，可见血栓形成及部分血栓机化；内弹力板变薄、消失或突然中断；在内膜及中膜部位主要为纤维母细胞、纤维细胞和大片胶原；部分动脉瘤壁呈均质状玻璃样变，平滑肌细胞明显减少；中膜和外膜可见大量的炎性细胞浸润；瘤壁组织有纤维母细胞、纤维细胞、大片胶原成分及较多泡沫细胞，胞浆内充满脂类物质及胆固醇结晶；部分动脉瘤腔内充满血栓，有的血拴已经纤维化，血栓基部机化，血栓表面有红细胞和纤维素。

While the transmission of laserpulse in plasma forms pulse compression, soliton and paired solions, and densitycavitation of electron and ion and so on.

而激光脉冲在等离子体中的传播过程中同样出现了脉冲压缩、产生孤子以及孤子对、形成电子和离子的密度空泡等现象。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
