The effects of mixed ratio and concentration on the spontaneous formation of vesicles in a cationic cetyltrimethylammonium bromide and anionic sodium dodecylbenzenesulfonate system were investigated.

讨论了十六烷基三甲基溴化铵/十二烷基苯磺酸钠复配比例、体系浓度对其囊泡自发形成的影响和不同制备方法与放置时间对囊泡尺寸的影响，同时用TEM考察了囊泡的结构与形态。

Under such a solidification condition that the growth rate is low and the temperature gradient ahead of the solidi fication front is steep, a large amount of α-Al nuclei can be produced by peritectic reaction, during which only metastable Al〓Zr particles or very fine equilibrium Al〓Zr particles rather than larger equilibrium Al〓Zr partiles are involved.

在低的生长速度和高的界面前沿温度梯度条件下，结晶前沿Al〓Zr粒子与液态铝发生包晶反应（只涉及亚稳Al〓Zr或尺寸极小的平衡Al〓Zr，而不涉及尺寸较大的平衡Al〓Zr）产生大量α晶胚，α晶胚呈球面生长，最终形成等轴非枝晶形态。

After been developing for three years,the basic structure and space morphology in center district has been finished.

经过近三年的建设，核心区的基本架构和空间形态已初步形成。

Spermiogenesis is a crucial process for germ cell formation, which ensures the efficient transmission of the paternal genome by the spermatozoa to the ooctyte at fertilization.

它包括染色质的压缩、顶体和鞭毛的形成以及去除多余的细胞质，是精子发生的一个重要环节，确保了成熟精子具有正确的形态和完整的功能。

These findings lead to an MSAP/septin-mediated model for flagellar differentiation during spermiogenesis.

免疫萤光定位分析显示septin7与MSAP共同位於精虫鞭毛的基底体上。septin蛋白家族可能参与细胞质分裂及细胞形态生成等事件，因此推测MSAP/septin复合体的功能可能涉及鲤鱼精细胞之极性建立及鞭毛形成。

Stalactites often composed of a variety of different forms, creating artistic conception is imagination and the vivid pictographic stones, while the high ornamental value.

钟乳石常会组成各种不同形态，从而形成令人浮想联翩的艺术意境和惟妙惟肖的象形石，而具有很高的观赏价值。

Starting from the situation of resistance against Japan, the author illustrate that many factors, which include the following: the tradition of learning and serving the country and stateism, the power thought, Nicai"s philosophy and the historical viewpoints of cultural pattern, have exerted parent influence on the formation of the Zhanguo Ce clique and that the Zhanguo ze clique"s political thought is the embodiment of the factors above.

笔者从抗日御侮的现实出发，揭示了经世致用的传统和国家主义，尚力思潮，尼采哲学以及文化形态史观对战国策派的形成产生了重要影响，在其政治思想中得到了体现。

Result showed that the epidermis dominant the morphogenesis changes. Mesenchymal is subdominant.β-catenin expression begin from horny placode epidermis stage and go up increasingly to peak value and maintain in hair follicle. The range of mesenchymal change is less.

结果表明，牦牛角的形态发生按照角基毛囊和角质外鞘发生与否分为5个阶段：角原基前期(Ed≤60)表皮增厚，无毛囊发生；角原基中期(Ed60~140)表皮持续增厚，有少量毛囊发生；角原基后期(Ed140~250)表皮变薄，大量毛囊发生；肉角期(≤0.5 a)真皮乳头发生；成角期(≥0.5 a)形成角质外鞘。

The probable cause and the controllingfactors in regard to the formation of sulphide inclusions in various morphologieshave been discussed.

对各种形态的硫化物夹杂可能的形成原因及其控制因素进行了讨论。
