最大变化

Results We know from the chest X-rays that the infant thymus is organ with the most change and it's usually looked like lobar-pneumonia,cardiomegaly and mediastinal tumor so that it brings much trouble to pediatrician and radiologist.

结果 婴幼儿胸腺是胸片中变化最多的器官，常酷似大叶性肺炎、心影增大、纵隔肿瘤等，给影像科医生和儿科医生带来不少的困扰。

During the two critical periods—gametogenesis and preimplantation development, there are genome-wide epigenetic reprogramming in gametes and embryos, which plays important roles in the erasion or creation of imprinting, gene silencing and tissue-specific gene expression.

其中关键时期是配子形成期和胚胎植入前期，最主要内容是全基因组DNA"CpG岛"甲基化和染色质组蛋白乙酰化的有规律变化，结果是配子遗传印记的消除与重建、植入前胚胎大范围基因的静默和组织特异性基因表达的确定。

Most importantly, in the present environment, movements in the money supply can be used to gauge the degree to which the excess bank reserves provided by the Fed are making their way into the broader economy.

最重要的是，在目前的情况下，货币供应量的变化可以用来估算，美联储注入的银行体系的超额准备金在多大程度上进入了整个国民经济。

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

Under the condition of changing in demand, this may lead to large minimum cost deviation between the designed optimal network and real optimal network, respectively.

往往造成构建出来的最优网络，在需求发生变化的条件下，与实际对应的最优解存在较大的最低成本优化偏差。

In this dissertation, the genetic algorithm is discussed in detail. In order to improve the convergence of GA, considering that it is important to choose the probability of crossover and mutation , new p〓 and p〓 were varied depending on the fitness values.

该方法在遗传模式得到保证的基础上，加快新个体的产生速度，所构造的交叉算子和变异算子随适应值自动变化，对远离最优值的个体采用较大遗传算子值，对接近最优值的个体采用较小遗传算子值，提高得至撮优解的概率。

Wine is one of the most popular and recognizable drinks in the world.

葡萄酒是最常见最流行的饮料之一，几个世纪以来葡萄酒并没有太大的变化。

The size of the gourd largely dictates the overall tone of each berimbau and there a three types, in order of decreasing size and rising pitch: Gunga – the lead berimbau holds a steady base line; Medio; and Viola – upon which the majority of improvised variations are played.

按体积由大到小的顺序（随着体积的减小，音调随之变高）排列，一共有三种不同的Cabaca：Gunga是其中最主要的一个，通常是大师亲自手持，用来演奏歌曲的基准音；然后是稍小的Medio；最小的Viola会被用来产生即兴的小节奏变化。

At best the NHS might expect no real growth in funding to 2014—a big change over funding trends to date (fig 3) and there will be considerable pressure to cut costs and improve productivity.

国家卫生事业局最多可能预期到2014年没有真正的资金增长--迄今资金趋势的一个很大的变化（图3），而且将会有相当大的压力去降低成本和提高生产力。

In this thesis, the comic art of David Ives, one of the most famous contemporary American playwrights, is looked into with reference to the development of comedy and universal comic devices, and a comparison and contrast between Ives" artistic creation and Chinese comedies is made in a hope that Ives" one-act plays may be of use for reference to Chinese comic drama. The thesis concludes that Ives can be of advice to Chinese playwrights in their understanding of the nature of comedy as an artistic genre and their selection and treatment of the subject matters in their comedies.

本文以喜剧作为一种话剧类型的发展变化为大环境，介绍了当代美国最负盛名的喜剧作家之一的David Ives及其最受欢迎的几部作品；依据喜剧令人感到滑稽，容易发笑的机制，分析了喜剧创作中常用的幽默设计，笑料制造的手法；在Ives的几个代表独幕剧剧作的基础上探讨了其喜剧艺术，并将此与中国大陆的喜剧创作进行比较对照，以期国内的喜剧作家们能从中受到某些启发，最终对中国喜剧创作的繁荣和进展起一定的借鉴作用。

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。
