The tension stress distribution of the aerostat envelope under windless condition is obtained using the FE model, and critical regions with high stress are pointed out. The calculated value of tethering force fits well with the theoretical one. The results are instructive for the safety evaluation and design of aerostat structures.

应用此技术建立了无风载条件下浮空器囊体张应力分布的有限元分析模型，给出了囊体的张应力分布情况并指出危险应力区域，对系留力的计算值与理论值吻合较好，计算结果对浮空器结构安全评估及设计具有一定的理论指导意义。

The results showed that 6% was the best concentration of separation gel for PSI complex separation. Part of PSI and amount of thylakoid membrane fragments contained with PSI complex could be solubilized by low concentration of Digitonin.

结果表明：6%的分离胶对PSI具有较好的分离特性；低浓度的毛地黄皂苷能够增溶间质类囊体上的PSI蛋白复合物，并能够获得大量的含有PSI的类囊体膜碎片。

The chlorophyll protein complexes of the thylakoid membranes solubilized with high concentration of digitonin combined sonication are isolated by means of nondenatured DOC-PAGE, and their biochemical and photochemical properties examined.

采用含PEG保护剂的提取介质提取类囊体，高浓度毛地黄皂苷与超声波破碎类囊体膜，非变性DOC-PAGE分离色素蛋白复合物。

And with decrease in light intensity,the shape of palisade mesophyllchanged from column into invert pyramid.The higher proportion of granum thylakoid,more granum in one ganum thylakoid and lower ratio of chlorophyll a to chlorophyll bwere also the responses of leaves to shading.

在庇荫环境中，栅栏组织薄壁细胞由全光的柱状变成倒锥形、叶绿素a/b率显著降低、叶绿体中基粒类囊体所占的比例提高、每个基粒类囊体垛的片层数量增加等，也是幼树提高叶片对弱光利用能力的主要标志。

In resting cysts, the microtubules under the pellicle, cortical ciliatures, conjunctions between cilia basal bodies, supporting structure of basal bodies and other microtubule structures are absorbed in different extent; microtubule-like assemble bodies appear at the center of the remained cilia basal bodies; the granules of chromatin and nucleolus in macronucleus become smaller whereas nucleus pores of the micronucleus become bigger; the inner membrane of some nucleus pores are attached with chromatin.

结果表明：纤毛虫形成包囊过程中，皮层细胞质中产生具有自噬泡消化特征的细胞器，将部分纤毛结构等逐步消化；休眠包囊中，表膜下微管、皮层纤毛器和纤毛基体间连接、基体托架及其他微管结构不同程度地被吸收、在残剩纤毛基体的中央形成微管形结构聚合体，大核染色质和核仁颗粒变小，核孔增大，并发生染色质附着于核孔内膜的现象；细胞脱包囊期间，皮层细胞骨架、线粒体等经历了在残剩结构基础上的再分化。

Those may be the structure for pyrenoid photosynthesis. The starch sheath embedded the pyrenoid. The pyrenoid could be divided into three types according to their structure.

并观察到蛋白核与叶绿体基质有多处联系，蛋白核内的类囊体发生膨大，并在莱茵藻蛋白核中观察到有数个类囊体堆积，这些细微结构功能还不清楚，可能与蛋白核行使光合功能有关。

Benign SO showed itself to be solid,cystiform or cystiform-solid.They were typically filled with gelatinoid and light green-yellow fluid.

其中，7例良性，体呈囊性、实性、囊实性，囊内为黄褐色胶样物和淡黄绿色液体；组织学类型有单纯型、腺瘤型、囊性变型。

A special delaminated expression was observed in the pericystic layer of hepatic hydatid cyst Collagen Ⅰ,Ⅲ and Ⅳ expression in the side of pericystic layer directed to the cyst of parasite(50 0%,37 5% and 40 0%) were lower than those in the side of pericyst...

靠近虫体侧纤维囊壁中，Ⅰ、Ⅲ和Ⅳ型胶原的表达阳性率分别为500%、375%和400%。靠近肝实质侧纤维囊壁中，Ⅰ、Ⅲ和Ⅳ型胶原的表达阳性率分别为875%、825%和850%。Ⅰ、Ⅲ、Ⅳ型胶原在两层中表达的差异均有显著意义(P01，P01，P01)。肝包虫囊肿周围人体纤维囊壁分层，Ⅰ、Ⅲ和Ⅳ型胶原与肝实质侧纤维囊壁的形成有密切关系。

The former formed a kind of KR cyst, while the later formed a kind of NKR cyst. All the kinetosomes, ciliary shafts and microtubules were resorbed in the former, meanwhile, the cell lost most water and cell volume decreased distinctly. In the later, only part of kinetosomes and part of microtubules were resorbed. Cell lost water slightly and volume decreased slightly.

期间，细胞吸收了全部的毛基体、纤毛杆和微管结构，伴随着细胞剧烈的失水浓缩，细胞体积显著缩小；游仆虫在形成毛基体非吸收型包囊时，细胞仅经历了部分的脱分化过程，期间，细胞仅吸收了部分的毛基体及部分微管结构，并且细胞仅发生了轻微的脱水和浓缩，细胞以折叠的形式容纳在包囊壁内。
