It has not given India's mobile operators enough space on the radio spectrum to carry calls crisply and reliably.

遗憾的是政府对此准备不足，没有为移动运营商提供充足的无线频谱来确保清晰流畅的通话。

First a hierarchically structured genotype is applied to represent cycloid parameters, and selection and mutation operators with evolutionary art are used to generate diverse patterns. Those with higher user rating are stored into the pattern database. Then fractal theory is introduced to configure these patterns on the basis of two distinct methods-Pythagoras tree design and Curlicue Fractal design.

采用层次结构化基因型表示摆线参数，使用进化艺术思想进行选择、变异操作，生成造型各异的花形图案，将用户评分较高的图案存入图案数据库；引入分形理论将图案库中的元件进行组装，提出基于Pythagoras树和花体分形原理的2套组装方案。

In Germany, the heartland of discounting, cut-price operators have some 30% of the market, according to Planet Retail, a consultancy, and shopping at Aldi and Lidl is the norm for rich and poor alike.

德国是折扣超市的中心。根据咨询公司Planet Retail的数据，那里的减价商店占取了30%的市场，去Aldi和Lidl购物成了富人和穷人共同的准则。

This thesis has mainly discussed D'Alembert Solution in one dimension wave equation by using arithmetic operators algorithm.

主要讨论了运用算子的方法推导出弦振动方程中的D'Alembert公式。

Objective To explore the metabolism of micronutri ents related to dark adaptation of radar operators through nutritional intervent ion.

目的通过营养干预，探讨雷达操纵员机体与暗适应有关的微量营养素代谢情况。

In the early stage of the genetic algorithms, the three genetic mechanisms are used both in integer part and decimal part, so that the genetic algorithms have stronger global search ability, keep the population diversity efficiently and avoid falling into local extremum. In the later stage of the genetic algorithms, the three genetic operators are used in decimal part, so the genetic algorithms have stronger local search ability and fast convergence ability.

在遗传算法开始阶段，该编码算子进行整数部分和小数部分的遗传操作，使得遗传算法在早期具有很强的全局搜索能力，避免陷人局部极值；在后期进行小数部分的遗传操作，使得遗传在后期具有很强的局部搜索能力，能够很快地搜索到全局极值。

The codingoperator expresses the genes with N-decimal system floating numbers, and then the genes are divided into integer part and decimal part. The two parts are encoded into chromosomes respectively. The corresponding selection, crossover and mutation operators are designed with the theory of symbol encoding and the properties of N-decimal system floating numbers.

该编码算子首先将每个基因值用N进制的浮点数表示，然后将其分为整数部分和小数部分，分别重新编码组成染色体；相应的选择、交叉、变异算子采用符号编码的思想，充分利用N进制浮点数的特点进行设计。

In Chapter 2, using space decomposition and block operator matrices, we study the infimum and supremun of operators in a complex Hilbert space with respect to the *-order.

我们给出了存在A和B关于Gudder序的上确界A∨_G B的充要条件并且我们也具体地给出了A∨_G B。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
