Some investigations suggested that cyclins and CDK played an important role in the regulation of endomitosis of megakaryocyte. However, the mechanism of cyclins and CDK in the regulation of endomitosis of fetal megakaryocytes during ontogenesis and the relationship between cyclins/CDK and retardation of endomitosis of fetal mgakaryocyte is totally unknown.

一些研究发现周期蛋白和CDK在巨核细胞核内有丝分裂的调控上起重要作用，然而，周期蛋白和 CDK在胎儿巨核细胞核内有丝分裂调控上所起的作用，及其与胎儿巨核细胞核内复制延迟的关系目前全然不知。

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。

Sinceβkernel is non-symmetric, there will be problem in the precision of graduation if using kernel graduation method, because, generally, kernel function is supposed to be symmetric in kernel graduation method, thus will cause boundary deviation in actual application.

但β核为非对称核，如果使用核修匀方法，在修匀精度上仍会存在问题，因为一般核修匀方法中均假设核函数具有对称性，在实际应用中将导致出现边界偏差现象。

To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.

Thischapter proposes three concepts,i.e.,kernelled quasidifferential,star-kerneland star-differential,and establishes their operational properties.A sufficiencytheorem and a sufficiency and necessity theorem for a quasi-kernel being a ker-nelled quasidifferential are proven.Both the existence of star-kernel for a qua-sidifferentiable function and the existence of star-differential for a directionallydifferentiable function are established.The relationships between sub-and su-per derivatives and Penot differentials are discussed as well.

Zen keeps leaping to the higher place while dodging the falling pieces of dark cloud and eventually reaches the top of the highest cliff nearby. He, afterwards, sets the arrow and draws the bow then aims the arrow at the devil core. The devil core of the devil king is not small but as standing at a distant place from the core, it looks only the size of a kid-playing ball. Moreover, the floating numerous dark clouds makes the aiming more difficult. It's unlucky that Zen's left eye is his "aiming eye" so even though he keeps blinking, there is no clear sight of the devil core before his eyes but a bloody-red, blurred image.

童战一面闪避暗云碎片，同时往高处跃，来到了附近最高的一处山崖上，弯弓搭箭，对向魔核；天魔的魔核不小，可是童战站的位置离魔核颇远，所以在童战看来，魔核不会比一颗小女孩玩的球更大，而且中间还隔著无数游移的暗云，更使瞄准困难，偏偏他受伤的左眼，是他的&瞄准眼&，他拼命眨著眼，但是总看不清魔核，只看见一片血红模糊的影像

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
