In chapter 2, we study how the circumburst environment influences the temporal evolution of the afterglow.

在第二章，我们以1998年5月19日发现的一个γ暴---GRB980519为例，研究了γ暴暴周环境对余辉随时间演化关系的影响。

You're just going to have to step it up a little: replace that liquid-measuring cup with a more accurate dry-weight scale; get a vacuum sealer like that FoodSaver gadget and a Crock-Pot that stays at a precise temperature so you can sous vide meat (which involves cooking it in a bag for a long time in a low-temperature water bath); learn how to use simple chemicals like agar-agar and xanthan gum (just better versions of gelatin and cornstarch, really); review a little high school chemistry.

你只需要循序渐进的学习：用更精确的干重测量代替液体量杯；准备一个真空密封器如FoodSaver，还有Crock-Pot，它可以让你保持准确的温度，这样你就可以随时调整肉的情况（包括放在袋子里用低温水煮食的肉）；学习怎么使用一些简单的化学品，如洋粉、黄原胶（实际上是明胶和太白粉的升级版）；复习一下高中化学。

I'm your agent and I'm always at your service.

我是您的代理，愿意随时为您服务。

If you are concerned about your dog's aggression issue's and are ready to take action right now.

如果您关心您的狗的侵略问题的，并随时准备采取行动的权利。

It provides inquiry service for peasants and basic agriculture technician and helps them to make a right decision, just like a well-know agriculturist guide the peasants on the spot.

为农民和基层农技人员提供各种农业问题咨询服务与决策方案，起到高层次农业专家随时都能亲临现场指导农业生产的作用。

In the middle of it lays a narrow tunnel, built as an air-raid shelter by Lin Biao. By that time, Chinese people were worried about the breaking out of the third world war. The oil paintings created in the revolution time was hung on the wall.

院子中间有窄下的通道走下去，那是林彪修建的防空洞——那是一个中国人担心第三次世界大战随时爆发的年代。

But, in the natural and artificial signal, a lot of signal phases don\'tvary linearly with time, for example, we usually use chirp signal in the radar technology,frequency step signal, linear modulation component of the ground echo in the SARtechnology, linear modulation component of the moving target echo, linear modulationcomponent while the airborn radar detecting the moving target, etc.

在自然界和人工信号中，许多信号的相位变化并不是随时间一次方变化，如雷达技术中常用的线性调频信号，频率步进信号，另外，SAR 技术中，地面回波所含有的线性调频分量，ISAR技术中，运动目标的回波所含有的线性调频分量，机载雷达探测运动目标时的线性调频分量，等等；傅里叶变换对此类信号分析所得的结果是信号在不同频率点上的能量分布，即信号在基函数上的投影。

Using an airgun as a repeatable seismic source and recording the data at a fixed point, the variation of shear wave splitting parameters can indicate the variation of local stress-strain fields, and hence provides a method for earthquake stress-forecasting.

气枪是高度可重复性人工震源，利用气枪定点激发和定点接收有可能精确获取S波分裂参数随时间的变化规律，为地震预测探索实践提供可靠的物理途径。

The shape of the cutter could be changed according to the practical situation because of the mobility of the contact points of the metal balls. And when cutting underwater, good effects were achieved because of the Mohaupt effect and airtightness of the hollow metal balls.

利用多个空心金属球之间接触的可移动性，能随时根据实际情况改变其外形；利用空心金属球的聚能效应和密封性，可以达到很好的水下爆破切割效果。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
