Research also shows that in different test condition, sensitivity, accuracy, and stability of bending creep test at 0 C are better than that of bending test at -10C. Thus, bending creep test at 0C can preferably evaluate the crack resistance of asphalt mixture at low temperature.

结果表明，老化过程大大降低了沥青混合料的低温抗裂性能，0℃弯曲蠕变试验比-10℃弯曲试验对不同的试验条件的区分度更大，试验误差更小，稳定性更好，可较好地评价沥青混合料的低温抗裂性能。

Online learning must be the main stream and online test will substitute the traditional paper-and-pencil test in the future. In order to respond to the coming of online learning era, how to make good use of the Internet is an important issue. Teachers can design online test questions to effectively understand students' learning performance and control their learning condition. Then teachers can provide remedial programs. Therefore, developing a flawless online test system to satisfy users' request is a critical issue both in practical and academicals.

网路学习必然是未来发展趋势，线上测验也逐渐取代传统考卷测验方式成为主流，为因应网路教学时代来临，如何善用网际网路让教师得以藉由线上测验之试题设计，而能更有效进行测验与验收学生之学习成效，且充份掌握学生之学习情况，后续即能针对能力较弱之处进行补救教学，因此，建构完善的线上测验系统以符合使用者需求，对实务界及学术界来说，都是一项很值得进行研究之议题。

The new launch schedule will enable us to complete the expansion of our internet-based testing operations worldwide.until the revised general test is launched, ets will continue to deliver the gre general test using the current network of secure, proctored test centers. pearlman notes that the graduate community has relied on the general test for 57 years and that ets is committed to continuing to deliver valid and reliable scores with both the current and revised general test.

首先，从去年关于新版gre内容方面的变革以及明年gre考试将采用网考形式的情况来看，gre改革的科学性进一步提高，同时此次新gre改革推迟并采用网考形式还得到了美国各大教育机构的认可；第二，gre考试的推迟为中国考生争取了更多的时间；第三，采用网考的形式也意味着新gre考试将有可能增加考点范围或是增加考试次数。

Until the revised General Test is launched, ETS will continue to deliver the GRE General Test using the current network of secure, proctored test centers. Pearlman notes that the graduate community has relied on the General Test for 57 years and that ETS is committed to continuing to deliver valid and reliable scores with both the current and revised General Test.

新东方学校 GRE考试项目专家分析，GRE考试改革是ETS系列产品周期性改革的一个组成部分，早前ETS曾经宣布将于今年10月份进行新GRE的改革，而此次将GRE改革推迟到2007年秋天并以网考形式推出，对于广大考生来说是一个利好消息。

To get a property comparison of GXHJ－ 1 sintered welding agent with SJ101 sintered welding agent, related tests were carried out, including deposited metal test, lab butt－ joint plate test, single－ welding stick operation test, double－ welding stick operation test as well as operation test with H08C welding stick, focusing differences of the two in terms of technological properties and weld seam impact toughness.

为了比较 GXHJ－ 1和 SJ101两种烧结焊剂的性能，分别从熔敷金属性能试验、实验室对接板试验、单丝焊生产、双丝焊生产等方面及在匹配 H08C焊丝的条件下进行了工艺性能和焊缝冲击韧性对比。
