上核

If we say that America's "Nuclear Umbrella" and "Missile Defense System" help maintain national security in Japan, then it is possible for Japan to continue to abide by the "Three Anti-Nuclear Principles".

但是，从现实角度来看，这二个核抑制力实仍为不完全，在保障日本安全上，仍未有相当程度的可靠性。此外，日本在接受美国的核保护伞守护之下，同时存在著要求美国废除核武器的矛盾。

On basis of study on the regulation of nucleator and nano-CaCO3 on small batch bulk PP, we put great emphasis on the discussion of the relation between two kinds of modification procedures.

在研究纳米改性和传统的β成核剂改性规律的基础上，重点探讨了两类改性方法之间的联系和协同改性作用。在小本体PP／β成核剂二元体系的研究中，主要比较了两种不同的小本体045、075的结晶性能和力学性能。

The development and availability of nucleoside and nucleotide analogues has greatly altered the management of patients with chronic hepatitis B.

核苷和核苷类似物的发展和应用很大程度上改变了慢性HBV患者的治疗。

Three different numerical iterative algorithms are developed and the accuracy and stabilities of them are compared. Tension and compression instabilities are studied and effects of Conservative Smoothing Approach and artificial viscosity on stabilities are discussed. Based on Taylor series expansion, Modified SPH method is proposed. The discrete forms of the function and its first derivative estimations of the kernel function are deduced in both one and two dimensional space.

讨论了三种不同的数值迭代算法对计算精度和稳定性的影响；分析了不稳定性产生的根源，包括拉伸不稳定和压缩不稳定，探讨了保守光滑算法和人为粘性对稳定性的影响；在Taylor展开的基础上提出了一种修正的SPH方法，并推导一维和二维情形下函数的核估计和函数的一阶导数核估计的离散形式，结果表明，二维情形下MSPH方法可以很好的改善边界粒子的计算精度。

Orthotropy of elastics properties was found relying on crystalline textures to much extent. In laminates, both stiffness orthotropy and fracture toughness depend directly on matrix properties that arise from changes in crystalline texture.

结合前人理论研究的结果，在大量实验事实基础上，提出碳纤维表面的面向成核也是PEEK在实际短纤维复合材料中常见加工条件下的界面直接成核方式，讨论了该特性与热应力一起，对材料微晶结构形成的作用。

With temperature increasing, granular outshoot prefer to grow along with vertical direction of surface of BN core, as well as the wrapped leaf-like shape form from granular ones. And the productions always kept complete morphology of sphere, which was due to the uniform growth of fluffy film on the BN core. Wrapped leaf-like structure of BN piece in fluffy film favored increasement of measured surface area and elimination of oxygen element.

凝并在球核表面的中间产物受到初始BN球核在空间上的诱导作用，随着温度的升高，突出物倾向沿着垂直于球面的方向向外生长，形貌由普通的粒状转变为卷叶状；绒膜的厚度均匀一致，产品得以保持规整的球状形貌，绒膜中卷叶状的BN结构利于氧杂元素的脱除，同时增加了比表面积。

At each penton, a hole (φ=20〓) can be seen connecting the inside and the outside of the capsid, and there is a hole (φ=12〓) at each hexton and the center of 2-fold axis, so there are 132 holes in total at the surface of CSBV.

应用冷冻电镜技术和计算机三维结构重构的方法，我们测定了CSBV核衣壳的三维结构，分辩率为25 〓，病毒的核衣壳是按T=1（P=3）的对称结构排列二十面体，病毒表面比较光滑，有12个五邻体、60个六邻体的结构，每个五邻体的中央有孔洞，六邻体的中央也有孔洞，另外在2次轴的位置上也有孔洞，这样病毒共有132个孔洞，五邻体的孔洞的直径为20 〓，而六邻体和二次轴的孔洞的直径月为12 〓。

The characteristics of glass microelectrode recorded electrical activity of nociceptive neurons in the caudate nucleus elicited by microinjection of GABA and blockage by picrotoxin were studied in 53 Wistar rats.

在53只成年W istar大鼠上，用玻璃微电极引导神经元放电，观察了尾核内注射Y-氨基丁酸后，尾核痛反应神经元放电的变化和印防己毒素(picrotoxin， PIC)对GABA作用的阻断效应。

Viral infection of the host cell may be switched on by the specific and stable combination of one or several viral envelope protein with one or several glycoprotein receptors available on the cell membrane, which is followed by viral pinocytosis or viral fusion with cell membrance, viral deenvelope, viral particle movement from cytoplasm towards nucleus and the viral gene passage.

病毒感染细胞可能是通过一个或几个病毒包膜蛋白与一个或多个细胞膜上的糖蛋白受体特异稳定地结合而启动，通过病毒胞饮作用或者病毒与胞膜融合、病毒脱包膜、病毒粒子从胞浆到胞核的运动和病毒基因通过核膜的传代将会发生；但参与这些动力过程相关的病毒、细胞结构和生化因子仍不清楚。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
