形成珠

And there was a revival of Middle Eastern glassmaking (at Turkey, near Afghanistan, Hebron, and Egypt梐ll making somewhat similar products, and some being familially related) in modern times, encompassing the past few centuries.

在土耳其，阿富汗附近，希伦布和埃及，在制作一些类似的产品，而且有一些形成了家族式的制作）在现代，包括以前的制作琉璃的一些国家，所有的都成为了琉璃珠的代表，第三世界琉璃珠制作商人。

The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

花药及胚珠的发育与花器官的形态发生之间有明显的连续性，当花蕾直径为3.0 mm左右时花粉母细胞及完整的花粉囊壁形成，直径达到3.5 mm左右时胚珠中出现孢原细胞的分化，它直接起大孢子母细胞的功能。

Lthough a low frequency of abnormal growthof nucellus was observed,no embryo originating from nucellus cell and integumentwas found.

PⅣ珠心组织出现低频率的异常生长现象，但未观察到由珠心细胞发育形成的不定胚。

Fetus skin, heterogenous skin of lineal consanguinity and self-skin obturate primeval burn sunface

垫珠被压进垫圈里，使得非常光滑的垫珠在垫圈里形成压扁密封。

In the plant, bead appearance of ovule be been in becomes an envelope.

在植物，珠被在胚珠外形成一个封套。

It is essentially composed of perlite rock which is heated to form a light, fluffy material similar to pumice

它基本上是由珠光岩构成的。当珠光岩受热时，形成轻的，松散的类似浮石一样的物质。

Double fertilization The fusion of one pollen nucleus with the egg to form the zygote and of the other pollen nucleus with a polar nucleus to form the triploid endosperm nucleus.

双受精：指花粉粒中的一个精子与胚珠中的卵细胞结合形成受精卵，另一个精核与极核结合形成三倍体的胚乳核。

The appearance of DNA ladder from the ovules in which pollen chamber formation was undergoing, together with TUNEL assay and ultrastructural changes, demonstrated that the nucellar cell death, doomed to bring about pollen chamber, was a process of programmed cell death .

在贮粉室的形态发生过程中，相关珠心细胞的DNA电泳出现DNA ladder、其细胞核被TUNEL反应所标记以及它们的超微结构变化都说明，参与贮粉室形成的珠心细胞的死亡是一种细胞程序性死亡（programmed cell death，PCD）。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

Now for the uncertain bit. When you add the Mentos, the arabic gum and the gelatin start to dissolve. The CO2 is attracted to the rough surface, which is a perfect nucleation site.

至於无法确定的部分是，当你加入曼陀珠时，阿拉伯胶和动物胶会开始溶解，二氧化碳会被曼陀珠粗糙不平的表面吸引，这种粗糙的表面最适合进行成核作用，因此上面会形成？

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
