The results indicate that:① Soot records is one of direct and effective means;② Overdriven detonation appears only once and several blasts appear in DDT (Deflagration to detonation transition);③ The dimension of acetylene is less than that of hydrogen under the same initial condition.

试验结果表明：①烟迹法是研究DDT更为直接和有效的手段之一；②在本试验条件下，观察到DDT过程中过爆只会出现一次，但从过爆衰减至正常C-J爆震波的过程中存在多次多点爆炸的迹象；③初始条件相同的情况下，乙炔的胞格尺寸小于氢气的胞格尺寸。

But being different from the others, drainage of the peripancreatic infection after the occurrence of SPI is very difficult, which needs many times of operation. Especially, the infection can be a vicious cycle, in which the systemic septicemia can be caused by localized infection or vice versa.

实际上，许多疾病的发生、发展和预后均与肠源性感染密切相关，但是SPI的特殊性在于发生感染后难以进行有效的手术引流、常常需要多次手术和多次置管引流，而且全身性败血症和局部感染交替出现，成为恶性循环。

Factory quality management group has also several times in the Ministry of·, Subbureau published results, and has won numerous awards. July 2006 production of I-foot gauge, gauge ruler test, and support from the ruler, support from the ruler test, and pressure gauge railway through the Ministry of Railways Administration permission in August 2006 more than 5 Products through measurement of the Shenyang Railway Bureau apparatus access qualification.

工厂质量管理小组也多次在部、路局、分局发表成果，并多次获奖。2006年7月我厂生产的轨距尺、轨距尺检定器、支距尺、支距尺检定器、铁路压力表通过铁道部行政许可，2006年8月以上五项产品通过沈阳铁路局计量器具准入资质。

At present, a good part of application program base on account and passwords for authentication. Each entering a system needs to import a pair of account and password. Now there are more and more inner enterprise application systems, if employees want to visit resources in these application systems, they have to be logged and certificated repeatedly, and it will greatly reduce the efficiency; In addition, each application system requires users to use strong countersign, and it will be a heavy burden on users to change and memory their countersigns, so it will cause certain information security risks to enterprises and employees.

当前，大部分应用程序基于账号和密码进行认证，每进入一个系统输入一次账号和密码，企业内部应用系统越来越多，员工要访问这些应用系统中的资源，必须经过多次登录与认证，大大降低了工作效率；另外，各应用系统要求用户使用强度较大的口令，更改和记忆口令成了用户的极大负担，为使用方便，很多用户将密码书写在电脑旁，这对企业和用户形成一定的信息安全风险。

The primary end point was a reduction of 50 percent or more from base line in the number of draining fistulas observed at two or more consecutive study visits.

以观察2次或更多次连续研究性随访的瘘管引流数，比基线减少50％或更多为主要目标。

Vice presidential candidate Sarah Palin, who's been impersonated several times on the comedy show, showed up to show off her sense of humor.

副总统候选人Sarah Palin，多次在喜剧中模仿表演，以此来表现自己的幽默感。听了N多次才听正确，真不容易。

Firstly, after getting predicted multiples, we use adaptive subtraction algorithm to eliminate multiples and get some inverse wavelets corresponding to every trace in one shot gather, then construct inverse wavelets domain by those inverse wavelets. Secondly, use median filtering method to get inverse wavelet estimation in inverse domain. Thirdly, correct the misshaped inverse wavelets in inverse domain by the inverse wavelet estimation.

其步骤为：首先用SRMA方法预测出表面多次波，并对每一单炮进行单道自适应相减，得到逆子波，形成逆子波域；其次，在逆子波域采用中值滤波，提取接近真实逆子波的逆子波估计；第三，在逆子波域用逆子波估计对畸变的逆子波进行校正；最后采用校正后的逆子波来衰减多次波。

Of course,the most important and most ominous devel.opment in these chapters,foreshadowed countless times in theearlier sections of the novel,is the reappearance of the convict,nOW a rugged old man,and the revelation that he,not MissHavisham,iS Pip's secret benefactor.

当然，这些章节中最重要、最具不详预示的情节发展，也是小说前几部分多次所预示的情节发展，那就是，现在那个已是饱经磨难的老人的逃犯再次出现，并道破匹普的秘密恩人是他，而不是郝薇香小姐。这在小说前几部分也曾多次预示。

At the same time, Mr. Li Xueqin, a historian, found it a perfect combination between Chinese history and aesthetics and insisted that the Complete Cyclopedia outshined Shu Dao Quanji of Japan in academic precisions since there were quite a lot of mistakes in Shu Dao Quanji.

历史学家李学勤先生则评价&全集&在&史&与&美&方面结合得好是一个特点，他认为日本的《书道全集》错误甚多，而《中国书法全集》在学术的精严方面远胜（刘正成曾经多次谈到，他编辑《全集》吸收了日本中田勇次郎先生的很多经验和教益）。

Then base on concept of energy dissipation, hysteretic behaviors of RC material, and experiential factors obtained from shaking table tests with repeated excitation, a deterioration rule for RC column after multiple earthquakes is established. According to the failure mode and damage condition in previous earthquake, the rule makes lateral force-deflection curve of RC column deteriorated by reducing stiffness and strength.

本文再根据能量消耗概念与RC材料之恢复力环特性，及由多次加载振动试验结果所得之经验参数，尝试建立RC柱构件之多次震害后折损规则，依构件破坏模式不同，对每次震后侧力-变形曲线加以刚度与强度逐次折减。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
