值群

Because of the infection of the animalcule's secretions, and the alkalescent shampoo or soap, or any other reasons, the acidic barrier is often destroyed. Once the PH value increase to the alkalescence level, the natural bacterium group will be resisted by the nosogenetic bacterium, and then leads to the inflammation.

由於微生物分泌物的影响，使用碱性香波、香皂洗头、洗脸的影响，或其他原因，其酸性屏障会遭到破坏，PH值升高到碱性范围时，正常菌群即会被致病菌压制从而发生感染。

The variability of threshold values for PTC is interesting because its threshold distribution is bimodal.

因为它的阈值分布是双峰的。换句话说，它的敏感性分布于两个相差很大的群组中。

A new particle swarm optimization, PSO with bounded mutation operator, was developed. In contrast to the original PSO, in this algorithm, PSO with bounded mutation operator would make the particles redistributed cquably close to boundary when place of particle exceeds feasible region during iteration.

提出了一种新的粒子群优化算法——带边界变异的PSO，其原理是：在迭代的过程中，当粒子的位置超出可行域时，带边界变异的PSO让粒子的位置重新均匀分布在边界附近；当粒子的速度超出可行域时，则使其均匀分布到整个可行区间，而不是像原始PS0那样在这2种情况下都只是简单地取边界值。

The conclusions show that with γP0 increasing the nonlinear dispersion curves shift to the negative region of δ,the upper branch of the curve will form a ring when γP0 exceeds a critical value,while the anomalous dispersion region of group velocity dispersion induced by fiber Bragg grating vanishes,group velocity dispersion becomes only one normal dispersion region.

结果表明：随着βg2的增加，非线性色散曲线的上、下两支向δ的负值区移动，当超过某一临界值时，曲线上支开始形成环，这时光纤光栅引起的群速度色散中的反常色散区消失，全部变成正常色散。

For a finite group G, an old theorem of Burnside asserts: each non-linear irreducible character of G must vanish on some element.

设G为有限群，古老的Burnside定理指出：G的每个非线性不可约特征标至少在一个共轭类上取零值。

We mainly consider completely monotone functions from semigroup to operator algebras.

我们主要讨论了作用在半群上取值于算子代数的完全单调函数。

Simulation results show that the proposed algorithm has a faster convergence rate and much less computational complexity, and the output bit error rate and signal-to interference-plus noise ratio performance are superier to the PASTd blind multiuser detection algorithm and close in on the singular value decomposition group blind multiuser detection algorithm.

仿真结果表明，所提算法收敛速度快，输出信干噪比和误码率性能优于PASTd盲多用户检测，逼近奇异值分解(singular value decomposition， SVD)群盲多用户检测，并保持了较低的计算复杂度。

In wetter habitats, forbs were more abundant and accounted for the majority of aboveground biomass, whereas grasses became more important in dryer habitats. Shrubs and sub-shrubs increased with decreasing soil water availability and their relative biomass rapidly increased in degraded steppe and sand dune; perennial grasses had significantly higherδ〓C values than other PFGs; the δ〓C values of perennial grasses and forbs increased with decreasing soil water availability, while those of shrubs/sub-shrubs showed an inverse trend.

在较湿润生境，多年生杂类草更加丰富并构成了群落地上生物量的绝大部分；而在较干旱生境下，多年生禾草在群落中起更重要的作用；随着土壤含水量下降，灌木和半灌木逐渐增多，且在退化草地和沙地中其相对生物量迅速增加；多年生禾草δ〓C值显著高于其它功能群；随着土壤水分可利用性降低，多年生禾草和杂类草的δ〓C值表现出增加的趋势，而灌木/半灌木则表现出相反的趋势。

Based on the evaluation of civil aircraft spare parts supplier s,this paper established an evaluational hierarchy containing criteria level and operation level to evaluate the suppliers in terms of quality,credit standing,competitiveness,response and service.

针对民机备件供应商的评估，从质量、资信、竞争力、响应以及服务等方面出发，构建了包含准则层与操作层的评估层次结构，其中操作层中定性属性信息以群决策、语意形式给出；准则层指标在权重信息与模糊语意量化词匹配的基础上，采用OWA算子的优化算法计算对应操作层的权重值；最后综合操作层的属性信息与权重信息，确定供应商的评估值，进而通过实例分析说明了本方法的实用性。

Then we work out the distinguished involutions of left cells in the two-sided cells of the arBne Weyl groups of type E with a-value 4, and we prove that these left cells are all left-connected , which verify a conjecture of Lu.

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
