寄生生物的抗药性是一个重大威胁，而采用青蒿素单一疗法则是疟疾扩散的主要动因。

It has also been shown that electrolytes will increase the conductivity and the efficiency of antistatic agents in preventing and/or dissipating electrostatic charges.

已经发现，电解质可以增加材料的导电性能，提高抗静电剂的效果，这就可以防止静电荷的生成或有利于静电荷的扩散。

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。
