According to the Logistic Equation and the impact of stochastic factors, a stochastic nonlinear dynamical model had been presenred. The max Lyapunov exponent was calculated by Oseledec multiplicative ergodic theory, the local stability conditions had been obtained; the global stability conditions had also been obtained by judging the modality of the singular boundary; the stochastic Hopf bifurcation was analyzed using the invariant measure of stable probability density, and the condition of stochastic Hopf bifurcation had been discussed. The key parameter impacting the urban domestic water consumption had been found by numerical emulation.

根据Logistic阻滞增长模型原理，考虑到诸多随机因素的影响，本文建立了一个城市生活用水量的随机非线性模型，运用Oseledec乘性遍历定理计算了模型的最大Lyapunov指数，得到了局部稳定性的条件；通过对扩散边界性态的分析，得到了全局稳定性的条件；通过分析系统平稳状态概率密度的不变测度，得到了模型随机Hopf分岔的条件，结合实际进行了数值仿真，得到了影响用水量的关键参数。

The error threshold becomes a narrow band which broadens and shifts toward large values of error rate with increasing fluctuation.

误差阈变宽，并且在涨落增加时向大的突变率方向移动。

The results revealed that marrow cells were younger, the diameters were larger. During erythrogenisis, the degree of decreased diameters became large. This phenominia was more apparent at the mature peried of mediate erythroblast or late erythroblast.

结果提示：灰尾兔骨髓内愈幼稚的细胞直径愈大，在成熟过程中直径变小的幅度逐渐加快，此现象在中幼红细胞发育成晚幼红细胞时最为明显。

Less obviously, the smaller the radius, the stronger the gravity and the greater the escape velocity, too.

容易忽略的是，行星的半径越小，它的引力和逃逸速度也变得越大。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

Recently Wang and Xiao discussed the excitation state energy of polaron in polyatomic crystals for the first time.

近年来国内外对多原子极性晶体中磁极化子性质的研究十分活跃，Zorkani等采用变分法计算了束缚磁极化子的基态能量，Kandemir等采用束缚朗道态讨论了二维大磁极化子的基态和第一激发态能量，国内一些学者采用微扰法和新颖算符法讨论了多原子极性晶体中表面和体磁极化子的性质。

Obviously your looks won't change drastically on the road, but depending on where you go, the same face that gets ignored in your local bar can be considered exotica.

很显然，在路途中，你看起来改变不会很大，但是随着你走到哪里，那些在你平时住的地方看起来的脸孔会变得非常性感。

The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

No longer can we expect the future to be just an extrapolation of the past plus faster and larger.

我们不再期望未来就是在过去的基础上变得更快、更大。

The shell of the liquid crystal auto-changing shade welding is made of high-performance plastic which is high strength and without leaking light. In addition to, by adding fire retardant and other special components , it has meet to the demand of inflaming retarding and could bear the high and low temperature .For resistance to impact, besides of choosing lightweight and high strength material, we also consider more in the aspect of the mechanics and human engineering in the design of the structure .In order to insure the comfort for wearing , we make the inside and outside protection piece and the shell of the face guard to a camber shape ,it also enhances the ability of resistance to impact.

液晶自动变光焊接面罩的壳体采用高性能的塑料注塑制作而成，高强度，不漏光，并通过在面罩材料里添加一定配方的阻燃剂和其他特殊成分，达到了阻燃和耐高低温等要求；为了抗冲击，除了材料选择轻质高强度材料外，在结构设计上更多的从力学和人体工程学方面考虑，保证了佩戴的舒适，而将内外保片与面罩壳体结合设计成能够最大承受外界力量的弧型，增加了面罩抗冲击能力。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
