但利用非标准有限元方法，对奇异微分方程进行研究的文章迄今很少见到。时空有限元法将时间和空间两个变量统一起来，在时间和空间两个方向上同时发挥有限元的优势，实现时间和空间两个方向的高精度。

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

经过二簇检验、分枝长度检验和相对速率检验，删除2条速率不恒定的序列后，用剩余的13条序列，以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。

Methods From June 2005 to March 2008, treated 20 cases of the nontuberculous mycobacteria hand infection patients after the start of functional rehabilitation treatment time were divided into Group A, B, each of 10 cases, both surgical debridement and anti-Mycobacterium therapy, rewirable after the first day until the wound for wound healing time, follow-up to 6 months after the operation, observe the wound healing time and the recurrence; according to the joint activity score standard score comparison group A, B group of before and after six months of the functional differences.

对2005年6月～2008年3月收治的20例手部非结核分枝杆菌感染患者按术后开始进行功能康复治疗的时间随机分为A组（术后1周）、B组（术后3周），每组10例，均行手术清除病灶和抗分枝杆菌治疗，以术后第一日起至伤口拆线为伤口愈合时间，随访到术后6个月，观察伤口愈合时间、复发情况；根据关节活动度评分标准评分比较A组、B组术前与术后6个月功能的差异。

The difference between the national "Code for design of metro"(GB50157-2003) and the NFPA130 "Standard for Fixed Guide-way Transit and Passenger Rail Systems" on calculation method for person evacuation time in the metro station fire is compared.

针对地铁车站火灾人员疏散时间计算方法的问题，比较研究国内现行《地铁设计规范》(GB50157-2003)和美国专门针对有轨交通系统的NFPA130标准的异同，其结果说明：国内设计规范关于人员疏散时间的计算方法存在不足；对区间隧道内列车着火的情况进行分析讨论，指出对列车在区间隧道内着火，且还能继续运行的情况，着火列车的运行速度对火势的发展以及人员疏散时间的影响是不可忽视的。

Objective To observe the effect of taking puer tea in different time on digestive system, investigating the mechanism of puer tea in stimulating the digest system and reducing blood fat, studying the best time to take the tea. Methods 100 mice were divided into 6 groups, including standard group, taking protein and tannic acid at the same time, blank group, taking protein and water simultaneously, two experimental groupsand, and two pre-experiment groups and , one of which took tea and protein at the same time, while the other take tea 10minuts later.

目的 观察不同时间饮用普洱茶对消化功能的影响，探求普洱茶促进消化道蠕动、调脂减肥的机制及最佳饮用时间方法本实验将100只小白鼠分设标准组、无茶组、同时加茶组、10min后加茶组及预实验组，实验结束时解剖观察，检测小鼠在餐时及餐后不同时间用普洱茶灌胃后的小肠推进度。

The board is not designed to handle the changeovers between standard and daylight time so during summer months the time may be an hour different from the real local time.

董事会是不是设计来处理该转换之间的标准和夏令时间，所以在夏季的几个月的时间可能是一个小时不同，从真正的本地时间。

In this paper, test research have been performed on the two important mechanical properties indicator compressive modulus of elasticity and shear modulus. Numerical simulation has been performed on the base of results of test under the situation uniform and uneven thickness of elastomer layer, which analyze internal stress distribution of the elastomeric bearing, as follows:(1) The traditional test methods of compressive modulus of elasticity test are rather cumbersome and take up experimentalists lots of time. This paper has improved the traditional test methods of compressive modulus of elasticity test, which has collected the holding-load time together to concentrate on holding load. The tests have been performed on different types of bearings, which results show that the results of the improved test method conform to the error range regulated by the standard and can effectively save time for the experimentalists, also eliminate the accumulative error.

本文主要对板式橡胶支座的抗压弹性模量、抗剪弹性模量两个重要力学性能指标进行试验研究，并在试验结果的基础上对均匀胶层厚度和不均匀胶层厚度两种情况进行数值模拟，分析橡胶支座内部应力分布规律，具体内容如下：(1)传统抗压弹性模量试验方法比较繁琐，占用试验人员大量时间，本文对传统抗压弹性模量试验方法进行了改进，将持荷时间集中起来进行集中持荷，通过对不同类型支座进行试验，试验结果表明该改进试验方法所得结果符合标准规定误差范围，为试验人员节省了大量时间，并且还消除了传统方法中的累计误差。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
