After Cold War, the status of Foreign Aid declined in the U.S national stratagem and its fund has been decreased to a level of less than a third of that in peak. After 9.11 Events, the global stratagem of the U.S changed in a large degree and transferred its core to Antiterrorism and anti-diffusion of weapons of mass destruction. At that time, the U.S drew its attention back to the Foreign Aid, such as Political Aid, Military Aid and Economic Aid, and took it as a powerful tool in global antiterrorist stratagem.

冷战结束后，对外援助在美国国家战略中的地位有所下降，美国对外援助的拨款一度降到不到其高峰期的三分之一的水平。9.11恐怖袭击后，美国全球战略发生重大转变，反恐和防止大规范杀伤性武器的扩散以保障其国家安全成为美国的核心战略，美国在全球展开了声势浩大的反恐战争，这时候，小布什政府开始重新重视对外援助，把对外援助当作其全球防恐战略的一个有力工具，政治、军事援助和基于政治、军事目的的经济援助在小布什么政府里又开始大行其道。

The basic concept in these sections is replacing backward Euler's method by modified backward Eulers's method to approximate the characteristic differential equation and discretizing the convection-diffusion equation at the middle point of the approximate characteristic curve, which will make the convective term get up to second order accuracy.

这三节的基本离散方法是用改进的Euler公式代替向后Euler公式来近似特征微分方程，并且将近似特征线的中点作为离散节点，使得对流项的离散精度提高到二阶，对于扩散项，将其转移到待求时间层进行离散。

Diffusion approximation theory is often used as basis of the experiments and methods in determining the optical properties of biological tissues.

漫射近似理论经常被用来作为测量生物组织光学特性参数实验和方法的理论基础，但是漫射近似理论只是一种对辐射传输理论的近似结果，在一定条件下有其特定的适用范围。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
