The results show that A-type granites in eastern China are of diverse crustal origins. They were either derived from anatexis of old lower crust or resulted from partial melting of recycling juvenile altered oceanic crust, and the latter has net contribution to the continental growth.

结果表明，中国东部A型花岗岩物质来源具有多样性，既可起源于古老下地壳深熔作用，也可由再循环年青蚀变洋壳通过部分熔融产生，后者是大陆生长的重要方式之一。

METHODS: Adipose was obtained from regions surrounding epididymis, retroperitoneal space and nape after anesthesis by pentobarbital, and adipose-derived mesenchymal stem cells could be harvested through type Ⅰ collagenase digestion. ADSCs were incubated in vitro and purified by differential adhesion.

戊巴比妥耳缘静脉麻醉，依次无菌取出附睾附近脂肪垫、腹膜后脂肪、颈背部脂肪，I型胶原酶酶解法分离出脂肪源间充质干细胞（adipose-derived mesenchymal stem cells，ADSCs），进行体外传代后差速贴壁培养纯化。

The negative arguments derived from Jewish Angelology and Satanology by the author of 'Supernatural Religion' are based on inaccurate and uncritical information, and do not require detailed discussion.

负面的论点来自犹太天使和Satanology作者的'超自然的宗教，是基於不准确的和无条件的信息，并且不需要详细讨论。

But may we not here once more and confidently appeal to impartial students whether, in view of this sketch of Jewish Angelology and Satanology, the contention can be sustained that the teaching of Christ on this subject has been derived from Jewish sources?

但是，我们没有可能在这里再次呼吁，并满怀信心地对学生是否公正，鉴於此画的犹太天使和Satanology ，论点才能持续的教学基督就这个问题一直来自犹太人来源吗？

基于面向对象技术，对鱼雷跟踪和垂直命中目标空间弹道进行了仿真和分析。

Theoretically the approximate conditions of the surface wave diffraction were analyzed,and the corresponding analytic expression of angle width of diffraction patterns was derived,which explained the asymmetry distribution well.

理论上对表面波衍射的近似条件进行了分析，得出了各级衍射条纹角宽度的解析表达式，解释了衍射条纹的非对称分布。

In comparison with existing models,the derived models possess higher accuracy,are applicable to high and low elevation angles and targets located in lower atmosphere and ionosphere,have no restriction of range,do not involve the problem of apparent elevation angle rate and are convenient in practice.

与现有模型比较，所得模型精度较高，适用于高低仰角，目标可在低层大气与电离层内，没有距离限制，不涉及视在仰角变化率问题，便于实际应用。

Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.
