"The government welcomes foreign investment in Australia and I will continue to ensure that investments are consistent with Australia's national interest," Wayne Swan, treasurer, said yesterday."In approving Sinosteel's application, I have determined that a shareholding of up to 49.9 per cent in Murchison will maintain diversity of ownership within the midwest region."

"政府欢迎外国在澳大利亚进行投资，而我将继续确保这些投资符合澳大利亚的国家利益，"澳大利亚财长韦恩·斯旺昨日表示："在审批中钢集团申请的过程中我已判定，允许其控制Murchison不多于49.9%的股权，将保持中西部地区企业所有权的多元化。"

By the secondary development of AutoCAD, the author performs post-processing of the result which returns from the server in AutoCAD. In AutoCAD, Stress and displancement are display in color nephogram like finite element analysis softwares used to do. This dissertation also introduces a method to build a value-color comparing bar.

通过对AutoCAD的二次开发，笔者将服务器返还回来的计算、优化结果在客户端的AutoCAD中进行后处理，实现了将构件的应力、位移等以业界通用的彩色云图的方式来显示，并介绍了在AutoCAD中创建数值—颜色对比条的方法。

The results show that the atmosphere has a big influence on the thermal stability of C_(60).C_(60) begins to decompose at 423.5℃in the air,the deomposed peak temperature is 668.5℃,but very stable in the helium atmosphere,only sublimate,the crystal shape of C_(60) has a certain influence to its thermal stability.The synthesized nine kinds of nitro-fullerene derivatives all have good thermal stability and their decomposed peak temperatures all exceed 350℃.The thermal explosion temperature for 5 seconds delay of product 4 is 253℃.The category,number and position of nitryl group in nitro-fullerene derivatives all have influence on their thermal stability.

利用差热分析仪和DSC-TG综合热分析仪对C_(60)及其硝基衍生物的热稳定性进行了研究，结果表明，环境气氛对C_(60)热稳定性影响很大，C_(60)在空气中423.5℃开始分解，放热峰值温度为668.5℃，在氦气中很稳定，仅表现为升华，C_(60)的晶型对其热稳定性也有一定的影响；合成得到的九种硝基富勒烯衍生物都具有较好的热稳定性，分解峰值温度均高于350℃；产物4的5秒爆发点测试结果为253℃。

Lesson 25 Non-auditory effects of noise May people in industry and the Services, who have practical experience of noise, regard any investigation of this question as a waste of time; they are not prepared even to admit the possibility that noise affects people.
