The incidences of 4 water-borne infectious diseases except bacteroidal diarrhea showed downtrends year after year in 10 past years.By relativity analyzing,there were negative correlations between overall incidences of 4 water-borne infectious diseases and the qualification rate of drinking water coliform group,between the incidence of hepatitis A and drinking water coliform, between the incidence of typhoid or paratyphoid and drinking water total plate countand between the incidence of typhoid or paratyphoid and drinking water coliform.

改水10年间四类主要介水传染病除菌痢以外均呈逐年下降趋势，经相关性分析，四类主要介水传染病的总发病率与饮用水大肠菌群、甲肝发病率与饮用水大肠菌群、伤寒副伤寒发病率分别与同期饮用水细菌总数和大肠菌群指标合格率变化之间呈负相关。

There were significant differences of the incidences of 4 water-borne infectious diseases(cholera,hepatitis A,bacteroidal diarrhea and typhoid or paratyphoid)between former 5 years and later 5 years.The incidences of 4 water-borne infectious diseases except bacteroidal diarrhea showed downtrends year after year in 10 past years.By relativity analyzing,there were negative correlations between overall incidences of 4 water-borne infectious diseases and the qualification rate of drinking water coliform group,between the incidence of hepatitis A and drinking water coliform, between the incidence of typhoid or paratyphoid and drinking water total plate countand between the incidence of typhoid or paratyphoid and drinking water coliform.

改水前后各五年霍乱、甲肝、菌痢、伤寒副伤寒等四类主要介水传染病总发病率的差异有显著性，四类主要介水传染病的总发病率与饮用水大肠菌群合格率之间、甲肝发病率与饮用水大肠菌群合格率之间、伤寒副伤寒发病率分别与同期饮用水细菌总数和大肠菌群指标合格率之(来源：A1eBC3737论文网www.abclunwen.com)间呈负相关。

Objective To determine whether antibiotic resistance probability of Coliform bacteria in sanitary sewage is in existence. Methods Coliform bacteria has been separated from Sanitary sewage samples of Nanning Langdong sanitary sewage plant,and its antibiotic resistance has been detected to seven kinds of antibiotics,including Benzylpenicillin, rythromycin, Ampicillin, Gentamicin, Cefazolin, Amikacin, Cefotaxime.

目的 检测生活污水中肠菌群对当常用抗生素是否有耐药性方法采集南宁市琅东污水处理厂初沉池中的水样，用管发酵法分离其中大肠菌群，采用药敏试纸扩散法，检测了分离出来的大肠菌群对七常用的抗生素包括青霉素、红霉素、庆大霉素、阿米卡星、先锋霉素Ⅴ、先锋噻肟和氨苄西林的耐药性。

The results showed that it would gain higher sustainable genetic respons and lower inbreeding rate when implementing BLUP selection in larger population. When the sire-dam ratio was too low, it would not only decrease the genetic response, but also increase the inbreeding rate. To gain higher genetic progress and acceptable inbreeding rate, it should keep enough large population size and feasible sire-dam ratio in practice.

结果表明，扩大育种群规模不仅可以获得更大的持续进展，同时还可有效缓解近交系数的过快上升；育种群中公畜比例过低时，不仅会降低遗传进展，群体近交系数的上升速度也会加快，实际中应保证育种群具有一定的规模和适宜的公母比例。

In order to preserve the varieties of the swarm and avoid to be in premature convergence,a Particle Swarm Optimization algorithm based on the differential evolution mutation is proposed.The new algorithm uses the particle aggregation quality to judge that if the particles in the swarm are congregative so much,then apply the differential evolution to mutate the self prevenient best position of each particle,in order to realize the aim of preserving the varieties of the swarm.

为了保持粒子种群的多样性而避免发生&早熟&的问题，提出一种基于差异演化变异的粒子群优化算法，该方法通过粒子聚集性判断如果粒子群中的粒子过于聚集，则使用差异演化算法对PSO算法中各个粒子的自身历史最佳位置进行变异，以实现保持粒子群种群多样性的目的。

This paper proposes the identity-based proxy signature scheme using the conjugacy search problem in the braid groups which are believed to be hard problem,and its security is also analyzed.

介绍了辫群的基本概念、两个重要性质和辫群中的困难问题，在此基础上，利用辫群上的共轭查找问题构造了一个基于身份的代理签名，并对它的安全性进行了分析。

Naturally, we can ask, in general, for the McKay quiver of G which is a finite subgroup of a generalized linear group, what its construction is and what relation there is with the conjugacy class of the group G.

我们自然会问：一般地，一般线性群的有限子群G的McKay箭图的构造如何以及它与群G的共轭类关系怎样？

In contrast with the detected space group of the crystal, the newly discovered ditrigonal scalenohedral negative crystal inclusions showed the m symmetry of the crystal with space group symmetry R 3c.

晶体中发现复三方偏三角面体的负晶包裹体，其宏观对称属3m，它与空间群R3c相对应，但与测出晶体结构的空间群有矛盾。X射线结构测定已否定了其空间群为R3m的看法。

Result:Results show that AchT immunoreactive neurons locate in dorsolateral and dorsomedial to genu of the facial.Few neurons scatter in the parvocellular nucleus.

结果：大鼠胆碱乙酰转移酶阳性传出性前庭神经元分布在面神经膝内侧E群、背外侧E群及脑桥尾侧网状核，以内侧E群为主。

"Palmar-plantar erythrodysesthesia typically presents with dysesthesia and tingling in the hands and feet, which usually appear 2 to 12 days after administration of chemotherapy," note the authors led by Domenica Lorusso, MD, from the department of oncology at Catholic University of the Sacred Heart, in Campobasso, Italy.

手掌脚掌红肿感觉异常，也称手足症候群或手至足症候群，是不舒服且相对常见的皮肤毒性反应，通常是对某些化学治疗药物；目对症候群仍所知不，为了厘清这个问题，专家于7月号癌症学志发表了一篇综论性文章，讨论如何处理这个不幸的不良反应
