At first, we introduce in detail relativistic mean-field theory, where a common Lagrangian density is presented. Starting with this Lagrangian density, we can obtain the Dirac equation and Klein-Gordon equations for nucleon and meson field by using Euler-Lagrangian equation.

本文首先详细介绍了相对论平均场理论的一些公式推导，给出了常用的一般的相对论平均场的拉格朗日量，从这个拉氏量出发，利用Euler-Lagrange方程就可导出核子与介子场的运动方程。

The air was always thick with threats of selling slaves south and of direful whippings, but there never had been a slave sold from Tara and only one whipping, and that administered for not grooming down Gerald's pet horse after a long day's hunting.

空气中总是弥漫着威胁声，如把奴隶卖到南方，狠狠地抽打谁，但从来没有一个奴隶从塔拉卖出，只有一次鞭打事件，那是因为经过一天的打猎，居然没有人为杰拉尔德的宝贝马洗刷照料。

These were commanded by Tlepolemus, son of Hercules by Astyochea, whom he had carried off from Ephyra, on the river Selleis, after sacking many cities of valiant warriors.

赫拉克勒斯掠劫过许多城市，里面住着强健、神祗哺育的壮勇，把她从厄芙拉和塞勒埃斯河畔带出。特勒波勒摩斯在精固的宫殿里长大。

Based on the similarity theory, two degrees of freedom flight test platform was designed to simulate the helicopter, then the platform was taken as the research object, and the Lagrange-Euler equation and the equivalent moment method were used to derive the system dynamics model, and the physical parameter was estimated.

基于相似性理论设计了具有两自由度的直升机飞行模拟试验平台，以该试验平台为研究对象，利用拉格朗日一欧拉方程与等效力矩相结合的方法推导出系统的动力学模型，预估了试验平台的物理参数；通过试验获得在固定总距角情况下直升机的升力随转速的变化关系。

结果表明，镍正极的法拉第电化学反应过程和碳负极非法拉第双电层过程可以很好的结合起来，体现出超级电容的充放特性。

The fossiliferous Middle Carboniferous and Permian are well developed in the Deri′angma-Xiala section in the Yunzhug area, Xainza County, northern Tibet.

西藏北部申扎县永珠地区德日昂玛-下拉剖面中石炭系和二叠系地层发育完整，出露良好，化石丰富。该剖面中查果罗玛组碳酸盐岩地层和下拉组碳酸盐岩地层之间的碎屑岩夹灰岩地层，在沉积上表现为冰海相杂砾岩，在古生物化石面貌上表现为特提斯-冈瓦纳古生物群混生。

Hilary Frankel and her friend, Lara Fox, spent a year trying to discover the keys to understanding between their parents and their peers.

Their living in poverty, but Jim and Alexandra respective owners as a very precious treasure - Jimujie a gold watch-even if the "basement full of gold and silver treasure, King Solomon is the gatekeeper, passing Jim Whenever there, Fed find out the table, so that King Solomon was blown beard Dengwenjing jealousy "; Delaware as a beautiful waterfall of hair can be" to show that the Palestinian Queen of pearls Baby Guizhou Ran pale."

他们啲生活贫穷，但吉姆和德拉各自擁有一样极珍貴啲寶物——吉姆祖传啲一块金表就算"地下室堆滿金银财宝、所罗门王又是守门人啲话，每当吉姆路过那儿，准会摸出金表，好让那所罗门王忌妒得吹胡子瞪眼睛"；德拉一头美麗啲瀑布般啲秀发则可以"使那巴示女王啲珍珠宝贝黔然失色"。
