形态形成

The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects. Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

This paper mainly studies on people Jui-Tu neglected to look further into these questions.:one, through the works of Zhang Rui Figure comprehensive carding, so can their have a comprehensive understanding; 2, the morphological changes from the works start, to explore its origins calligraphy; 3, through their works shall know Handscroll analysis to help determine without the banners section in the approximate age of the work; 4 of their book to learn the concept of analysis, in order to more clearly understand the formation process of calligraphy styles. 5. Allograph home and at the same time learn the concept of the book, we can know that the formation of personality style and its concept of an independent study of the book is closely related to, but also deepen their understanding of the law of Zhang Rui.'s calligraphy.

本文主要就人们研究张瑞图时所忽略的一些问题做进一步的探讨：1、通过对张瑞图作品的全面梳理，以求能对其有一个全面的认识；2、从其作品的形态变化入手，探寻其书法的渊源，并尝试对其书法上一个很长的空白期进行探索；3、通过对其手卷作品进行款识分析，以帮助对无年款的条幅作品进行断代；4、对其书法观念进行论述，以求更清晰地理解其书法风格的形成；5、与同时代书家书法观念的比较，可以知道个性风格的形成与其独立的书学观念密切相关，更能加深对张瑞图书法的理解。

On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

Mao Zedong Thought is a scientific concept bearing special meaning. In the early 1930s, MAO Zedong systematically proved the feasibilities of "enveloping the cities from countries and taking over power by armed forces". He also established three essentials in MAO Zedong thought: seeking truth from truth, mass line and independence, in his Fighting against bookishness, which became a milestone in the formation and development of MAO Zedong thought.

摘要］ 毛泽东思想是具有特定含义的科学概念，农村包围城市道路理论和毛泽东思想活的灵魂构成毛泽东思想的基本形态。1930年初，毛泽东比较系统地解决了关于农村包围城市、武装夺取政权革命新道路的一系列基本问题，同年5月，他发表《反对本本主义》一文，初步论述了毛泽东思想活的灵魂的三个基本点，即实事求是，群众路线，独立自主，从而成为毛泽东思想形成和发展的一个里程碑，标志着毛泽东思想的基本形成。

The clothes hung on the body with one-piece cloth like Chiton and Himation of ancient Greek and Toga of ancient Rome etc emphasized on the graceful frills formed when being hung,which also formed a special type of clothing shape and dressing way distinct from Chinese traditional clothes.

古希腊的"希顿"和"希玛纯"、古罗马的"托加"，这些用一块布披挂在身上的衣服，强调披挂时形成的优美的垂褶效果，这也形成了区别于中国传统服装形态和着装方式的一种独特类型。

Lava from the earth's crust deep place, because the earth's crust deep place's temperature is extremely high, the lava by the volcano rock magma's shape existence, along with the volcanic eruption, the rock magma also spouts the surface along with it, meets the water or the low temperature starts to congeal, because the congealment process air entry, turned solid the rock magma to form the massive air bubbles gradually in the interior, coagulated after completely, has formed the structure unique lava.

火山石来自地壳深处，由于地壳深处的温度极高，火山石以火山岩浆的形态存在，随着火山喷发，岩浆也随之喷出地表，遇到水或低温开始凝结，凝结的过程由于空气的进入，逐渐变成固体的岩浆在内部形成了大量的气泡，完全凝固后就形成了构造独特的火山石。

Hence, it limited the spherulite congeries structure and a symmetrical bi-continuous morphology dominated all the membrane body.

结果显示，CaCO_3粒径及添加量对膜结构有明显的影响，一定量CaCO_3粒子的加入影响了PVDF结晶动力学，因而影响PVDF聚集形成大球状结构，更有利于均匀分布的双连续形态的形成。

In the first stage, the initial of morphologization of cormel happened, corresponding with the period from 4 leaf to full-blown, the growth and development of stolon mainly occured, while the number of cormel was a few and its weight slowly increased.

籽球生长发育表现出阶段性，第一个阶段为籽球形态建成初期，对应于地上部4叶龄期至盛花期，以匍匐茎生长发育为主，形成籽球数量少，籽球重量增长缓慢；第二个阶段为籽球快速膨大期，对应地上部盛花期至半枯期，籽球大量形成，籽球重量迅速增加，该阶段末期籽球逐渐成熟，生长发育进程减缓。

The isothermally crystallized films of the low temperature fractions of the two PPEs possess the similar crystalline morphology, i. e., thinner and high content of cross-hatching lamellae. The main reason to create the different crystallization behavior between the two PPEs and their fractions was due to the different distribution of the copoymerized ethylene unit.

对于分级样品，PPE1和PPE2高温级份的结晶行为差别较大：PPE1的高温级份结晶时形成的片晶较厚并且交叉片晶的数量也较低，剪切时产生较多纤维晶；两个样品的低温级份结晶形态类似，即结晶时形成的交叉片晶的含量都较高，剪切产生纤维晶数量差不多。

Now the model research has been use to explore the affection of the gene on the plant growth, and the virtual plant had been probed into from three level, i.c., micro level, individual level and the macro level.

现在，已经发展到了微观水平，开始研究基因与植物形态关系，形成了以虚拟植物模型为中心，以植物个体形态为主导的宏观、中观和微观3个层次的研究格局。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
