无目的

The TCR firing angle can be fully changed within one cycle of the fundamental frequency, thus providing smooth and fast control of reactive power supply to the system.

即不管负载的无功功率如何变化，总要使二者之和为常数，这个常数等于电容器组发出的容性无功功率的数值，使取自电网的无功功率为常数或为0，即：=常数（或0），最终使得电网的功率因数保持在设定值，电压几乎不波动，从而达到无功补偿的目的，以抑制负载波动所造成的系统电压波动和闪变。

objective: value the no tention hernia ring padding neoplasty in treating inguinal hermia.method: retrospectively analysize the clinical data of the no tention hernia ring padding neoplasty.result:the average time of the neoplasty is 40 minutes,the patients can make out-of-bed activity ,whom were treated after 6 hours.all of the patients were free of infection.2 patients felt foreign body sensation in inguinal groove and 1 person felt benumbed.conclusion: no tention hernia ring padding neoplasty is a valuable type of neoplasty,which operates simply,and the patients can get little injury ,rapid recovery and low relapse rate.

目的：探讨无张力疝环填充式修补术在腹股沟疝手术中的应用价值。方法：对30例腹股沟疝患者行无张力疝环填充式修补术后的临床资料进行回顾性分析。结果：手术时间平均40 min，切口疼痛2 d～7 d，术后6 h下床活动，无感染病例，腹股沟异物感2例，麻木1例。结论：疝环填充式无张力修补术是一项更符合生理解剖结构的治疗技术，操作简单，损伤小，恢复快，复发率低。

In this study, we discussed the phylogenetic relationships in the Anura groups with the sequences of the 12 proteins encoded in the H-strand and 22 tRNAs of mtDNA from 21 species from GenBank. They all indicated that Anura were divided into the Archaeobatrachia and the Neobatrachia,these results supported the monophyletic origin of Anura.

结合饰纹姬蛙和金线蛙的mtDNA以及GenBank上公布的共21种无尾目的线粒体基因组，本文基于编码重链12个蛋白质的基因和编码22个tRNA的基因分别构建了MP系统树，分析了21种无尾目动物的亲缘关系，结果都显示将无尾目分为两大群，支持无尾目的单系起源。

On comparing with the common type 4, there are 18 genes presenting change in the rest 21 types, most of them are tRNA genes, and gene replacement, gene increase and gene absence are frequently happened; on the contrary, protein genes are more steady, gene change is mostly of gene replacement. The genome size of Gymnophiona are all smaller than 18000 bps and most of them range from 15000 to 16000 bps, those of Urodela and Anura are bigger than 16000 bps, most of Urodela range from 16000 to 17000 bps, most of Anura range from 17000 to 18000 bps.

与类型4比较，其余21种线粒体基因组类型涉及基因变动的基因共有18个，其中变动比较多的是tRNA基因，移位、增多和缺失的发生频率都较大，而蛋白编码基因比较稳定，主要是移位。78种两栖动物中，蚓螈目的线粒体基因组均小于18000bps，多数在15000~16000bps；有尾目和无尾目均大于16000bps，其中有尾目多数在16000~17000bps，无尾目的多数在17000~18000bps。

Research purposes:Through doing overall researches,it is proposed to adopt flat-slab beamless pile structure for low embankment of soft weak subgrade,which can be suitable for ballast and ballsatless tracks and control the structure s settlement with easy construction and low construction cost.

研究目的：通过全面研究，提出软弱地基低矮路堤采用无梁板桩柱结构，保证结构可适应有碴及无碴轨道，达到结构沉降可控，施工方便，造价经济的目的。

Both a prequel and a reboot, Star Trek introduces us to James T. Kirk (Chris Pine of The Princess Diaries 2 ), a sharp but aimless young man who's prodded by a Starfleet captain, Christopher Pike, to enlist and make a difference.

既是前传和重新启动，向我们介绍星际旅行詹姆斯寇克（克里斯派的公主日记2），尖锐的，漫无目的的年轻人谁的，刺激了一个星际舰队队长，克里斯托弗派克争取并有差别。

Life is like the sky and fly a kite, the children, do not because the lines of "yoke" and you do not complain about free, not to get rid of it and with the secular purpose of the wind around to random drift of to.

而人生就像一只天上飞的风筝，孩子，千万不要因为线的&羁绊&而抱怨你没了自由，更不要挣脱了它而随世俗的风到处去漫无目的的去飘荡。

And that from then on it is necessary to have an intelligent plan if progress is to be made.no haphazard hit-or-miss methods will do.

从那以后，要想继续扩大词汇量就要有一个精心设计的计划。随意安排的、谩无目的的计划是不起作用的。

No haphazard hit-or-miss methods will do.

随意的，漫无目的方法是不起作用的。

Most all creative endeavors are somewhat unpredictable. They often seem ambiguous, hit-or-miss, trial and error.

绝大多数创新性的努力都难免有不可预见性，它们经常被认为是模棱两可、漫无目的难以成功、反复尝试的行为。

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。
