Tapetum cells degenerated and only ER small vesieles were the visible organelle at the 2—celled pollen stage.

绒毡层在小孢子液泡化中期开始退化，开始退化的绒毡层表现为内质网腔膨大，核周腔增大，核孔数增加。

Metastasis: A process in which that the tumor cells invade into vessels or coeloms and are transferred through blood, lymphatic and coelomic paths to other parts of body where they implant and grow into a secondary tumor.

定义：肿瘤细胞浸润到淋巴管腔、血管腔或体腔随体液运行或经体腔种植被带到它处，停留继续生长形成与原发瘤类型相同的肿瘤。原发瘤，继发瘤

Zn-diffused high power 650 nm AlGaInP/GaInP material with compressively strained multi-quantum-well active layer was fabricated. The zinc diffusion was used on the material facet in a sealed quartz tube. Photoluminescence spectra shows 175 meV blue-shift in the Zn diffusion area, which is transparent for 650 nm laser emission.

利用石英闭管法对金属有机化学气相沉积外延生长的应变量子阱650 nm AlGaInP/GaInP材料进行选择区域扩Zn，使扩Zn区域的光致发光谱的峰值蓝移达175 meV，形成对650 nm波长激光器的高透腔面，有益于减少激光器腔面光吸收，增加了激光器退化的光学灾变损伤阈值。

The self-pumped phase-conjugation with external ring cavity for SBN:Cu is demonstrated.Theexperimental results show that its phase conjugate reflectivity canreach 50%.With the self-pumped conjugator,an light wave withaberration caused by a distorter is corrected.

另外还研究了SBN：Cu晶体环形腔自泵浦位相共轭镜的基本特性，得到高达50％的位相共轭反射率，并利用SBN：Cu晶体环形腔自泵浦位相共轭镜消除了信号光波的位相畸变。

The cavity in core zone gradually turned bigger with longer culture time, whose volume was more than half of the whole inner structure at cell contabescence phase.

随着培养时间的延长核心区内的空腔逐渐增大，生长衰亡期的细胞聚集体空腔占据二分之一体积还多。

Some aggregates had discernible lumens, either empty or containing erythrocytes, lined by plump, cuboidal, or flat endothelial cells.

有的结节中可见血管腔隙，中空或含有红细胞；腔面衬覆胖圆形、立方形或扁平内皮细胞。

BCPA can provide increased pulmonary blood flow in patients with cyanotic congenital heart disease and reduced pulmonary blood flow.

BCPA是上腔静脉或腔静脉的体静脉回流血分流到两肺的一种手术，这种手术连接可以增加肺血减少的紫绀型先心病的肺动脉血流。

White cystiform tissue was evident on the back of mice subcutaneously in each group.

各组小鼠背部皮下均可见一白色的囊腔组织，各时间点A 组囊腔直径大于B、C 组，C 组小于B 组。

Iteration is needed in complex misaligned system.The range for tilt misalignment that can be figured out is 0～10~4 urad and the decentration range is from 0 to 1mm.

这种辅助装调方法能够有效的指导谐振腔的精装调过程，为今后实际的激光器谐振腔系统的自动精密调节提供了一种方法。

The main pathological findings include a desquamative interstitial pneumonia-like reaction with intra-alveolar macrophages and numerous large multinucleated histiocytes that ingested inflammatory cells were admixed with macrophages.

GIP主要病理表现有脱屑性间质性肺炎样反应，即在肺泡腔内有巨噬细胞和大量的多核巨细胞聚集，位于肺泡腔内的多核巨细胞内可见被吞噬的炎性细胞，是GIP的特点。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
