The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.

在已有分析法得到t时刻平均根数的基础上给出一种轨道预报方法，由t时刻的平均根数给出该时刻卫星的位置和速度，在此基础上将地球非球形引力摄动的周期项直接用卫星直角坐标的位置和速度分量表示，这样可以避免在计算轨道根数变化的周期项时出现的奇点问题，从而对根数的选择无特殊要求，可适用于各种轨道，简化预报程序和相应的软件，提高预报效率。

Studies on mineralogy, isotope and trace elemental geochemistry of the pegmatite will make it possible to reveal the principals of petrogenesis and evolution of pegmatite, and the geochemical behaviors of rare-earth elements and other trace elements in magmatic-hydrothermal transition stage.

由于LCT型伟晶岩具有明显的分带性、矿物颗粒大小不均匀性等特点，因此利用全岩样品研究伟晶岩往往因取样没有代表性而被大多数岩石学家和地球化学家所否定。

Yin-Yang is a very important theory in the history of Chinese philosophy. The elements of yin-yang theory emerged very early and were implied in astronomy observation and phallicism in ancient China.We will see that the two elements of "yin"and "yang" obviously derive from man and women.

By applying object-oriented analysis method, the device elements in power system are used as research objects in phase coordinates for network modeling and fault analysis. The symmetrical feature of power system elements is studied and optimized calculation methods for various application environments are developed.

本文以电力系统设备元件和网络节点为主要研究对象，利用面向对象的分析方法，在相坐标系下对网络建模和故障处理作了深入的研究；分析了电力系统元件的对称性，为各种不同应用环境研究了实用化的优化计算方法。

There may be a lack of trace elements, especially zinc, the main manifestation is pica, eating some things can not eat, such as mud, cinder and so on, there may be hyperactivity, inattention, and can go to the hospital so Determination of trace elements.

另外可能是缺少微量元素，尤其是锌，主要的表现就是异食癖，吃一些不可以食用的东西，如泥土，煤渣等等，还有可能多动，注意力不集中等，可以去医院做个微量元素测定。

The finite element models of two types of machine guns are set up, mainly based on the 3-dimensional beam elements, partly based on boundary elements. Modal experiment plan of the machine guns is designed and their modal analysis experiments are done. The inherent properties of structural vibration and dynamic response properties for type-02 14.5 mm anti-aircraft machine gun and type-89 12.7mm machine guns are completely realized through the method combining theory and experiment, and many valuable conclusions are obtained.

建立了以三维梁单元为主，边界元为辅的高射机枪和重机枪有限元模型，设计了模态试验方案并进行了两支枪的试验模态分析，采用理论与实验相结合的分析方法，全面揭示了 02 式 14.5mm 单管高射机枪和 89 式 12.7mm 重机枪的结构振动固有特性和动力响应特性，获得了许多有价值的结论。

Slight platforming elements and an energy collection system similar to that of Onimusha have been incorporated as well, and players are even able to use certain elements of their fallen enemies as a weapon (re: Medusa's head, for instance, can be used to turn enemies to stone after you've defeated her).

游戏运行中还包含了类似于"鬼武者"的吸魂模式。当然还有一些敌人的某些部位可以用来作为武器，例如美杜莎的头颅：用它可以将面对你的敌人石化，从而进行致命一击。（转载自IGN.COM/翻译：valentine

The two elements of a lower pair have theoretical surface contact with one another, while the two elements of a higher pair have theoretical point or line contact.

The results show that the samples are of calc-alkaline series, the primitive mantle normalized trace element patterns are characterized by relative enrichment in large ion lithophile elements and depletion in high field strength elements (Nb, Ta, Ti, P etc.). REE patterns are of slightly right inclined type with unobvious Eu anomaly.
