早熟性的

The least paedomorphic behavior pattern may be that of the basenji , bred in Africa to hunt alongside humans almost on a peer basis; this breed is often described as highly independent, neither needing nor appreciating a great deal of human attention or nurturing, often described as "catlike" in its behavior.

证明狗是从狼快速进化的一个例证是狗是性早熟或幼态持续的。跟大多物种一样，如小狼比起成年狼更偏向群居和比较少的具有支配力；因此，当进行优选时，不管是有意或无意的，最终的结果看来似乎是把这种幼体的特性带入了成年种群中，而非产生一个复杂的独立新行为。对包括人类自身的许多驯养动物皆是如此，人类很多特征与幼倭黑猩猩类似。这种幼态持续选择的结构自然是导致了幼体生理特征的保留。

Improved standard of living now, the age of menarche for girls was also quite a bit, after I was 80, I remember when the 2056-level class girls have periods, and since it is not precocious puberty, so parents should be actively to face with the children, not to what self-reproach.

现在的生活水平提高了，女孩子初潮的年龄也提前了不少，我是80后，记得上五六年级的时候班里就有女生来月经了，既然不是性早熟，做家长的应该积极地去同孩子去面对，不要再自责什么了。

The death rate grew by 37%. Chinese previously did not need security door. But by now, to some place, security window has been set at seventh floor. For there are too many gangster every where, no company in China would arrange with their workwomen to go home at night. No body knows what really are the food every one have everyday. Neoteny has take place on children. Then we can imagine the situation of our health in the future. There are about 20 million girls in China are pursuing sexual work. That creates 6% of GDP aggregate, which is as much as 1000 billion RMB. This kind of activity had never appeared in the history of human being except Japan. The height of Chinese people is 2.5cm lower than that of Japanese. We can no longer see them by looking down. The small Japan became big Japan. We create 0.1 billions GDP with the payment of 1 person's life, reported by reference news. The number of death in 2003 is 136 thousands. So the number of industrial injury will be 200 thousands. It is true that our GDP is bloody. Actually, this number is a small part of the true number. The numbers which can be accounted are in nationalized business or in a big accident. In personalized business or overseas-funded enterprise, the owner do not pay attention on the death of workers. So the data can not pass to the statistical department. However, the number of death there is much more than that of the first ones. If we add this in account, the number,annually can be compared with the massacre in Nanjing.

中国人从原来不知道防盗门窗为何物，到现在防盗窗已安装到了楼房的七层以上；由于流氓遍地防不胜防，全国企业早已不再安排女工上下夜班；有毒食品已经100%的覆盖了全部行业，每天人们咽进肚子里的食物究竟是什么，只有天知晓；性早熟现象已经蔓延到了学龄前儿童，未来的身体和寿命可想而知；约2000万少女被迫卖淫，创造的收入占GDP总量的6%，相当于一万多亿人民币，这种肉体积累是世界历史上除日本之外绝无仅有的现象；中国人的平均身高比日本人低了2.5公分，由以前低头看日本人到现在抬头看日本人，小日本真的成了"大日本"；《参考消息》报道，中国每亿元GDP工伤死亡1人，2003年死亡达13.6万人，以此推算，今年工伤死亡人数将达到20万，"是名副其实的带血GDP"，其实这个死亡数字不过是冰山一角，能够统计到的死亡数字，要么是国有企业，要么是死人较多的特大事故，私企和外企平常死个把人根本到不了统计部门，而私企和外企用工数量远远超过国有企业，如果考虑到这个因素，每年死亡人数至少相当于一场南京大屠杀。

With the amplification of farming scale and increase of yield, a series of problems to be resolved urgently appear in production, for example: Bad ovary development of female crab, inclining egg-holding rate, high mortality of embryo development, low survival rate of juvenile crab, the shortage of good quality juvenile, precociousness of crab etc.

随着河蟹养殖规模的扩大、集约化程度和产量的提高，在实际生产中出现了一系列亟待解决的问题，雌蟹亲体的性腺发育不良、抱卵率下降、胚胎发育死亡率高、幼体育成率低、质优量足的苗种供应不足、河蟹性早熟等问题，都严重制约了河蟹养殖业的健康、稳步发展。

Result,along with the development of society,The incidence of disease of child sexual precocity take advantage of obvious rising, City is more high than rural incillence of diecase.The theory of Chinese medicine think that it is concerning with function of liver and kidney and occur of Tiangui.

结果随着社会的发展，儿童性早熟的发病率呈明显上升的趋势，而且城市比农村发病率高，中医认为这与肝、肾二脏功能及天癸的期至有关。

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。

Exposures to either E or MXC did not change sex ratio at birth, but the litter size was smaller in the former group; On postnatal Day 21, male pups exposed to either E or MXC at early pregnant stage exhibited shorter AGD than the controls, with the change most pronounced after MXC treatments. AGD in female offspring was unaffected after MXC exposures, but E treatments produced longer AGD in the females than that recorded in the controls; early pregnant exposures to E or MXC also accelerated sexual maturation as significantly more females exhibited precocious vaginal opening at weaning; In males, MXC exposure during early pregnancy decreased serum LH and FSH, but not testosterone levels.

但是雌二醇处理组雌性小鼠的AGD比对照组记录更长；③孕早期暴露雌二醇或MXC也加速性成熟，表现为更多的雌性小鼠在断奶时出现明显早熟的阴道开放现象；④MXC处理组的雄性小鼠可降低血LH和FSH但是不改变睾丸酮水平。

Exist manifold types breeding materials in test field, manifest abundant germplasm resource, obviously existent prematurity type and late-maturity type . It is very difference of phenological phase, plant height, laminae area, chlorophyl content, stern diameter, seed production ,colour and shape of inflorescence and spike, yield of grass et al.

试验地引种驯化的猫尾草中存在着多种类型的育种材料，表现出丰富的种质资源，明显的存在着早熟、晚熟两种类型，这2种类型的材料在物候期、株高、叶面积、叶绿素的含量、茎杆直径、结籽性，花序及穗的颜色与形状，产草量等方面存在很大的差别。

Therefore, physio-chemical measurements in the laboratory were synthesized with the field observations to use stress-resistant index to sequence and cluster. Among the 20 Kentucky bluegrass varieties, 2 have strong stress resistance, 15 are medium, and 3 are low.

为此，将实验室测试的生理生化指标与田间观察结果加以综合，用杭逆性指数进行排序和分类。20个草地早熟禾品种中，抗逆性强的有2个，中等的15个，差的3个。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
