can not approach

We can not arbitrarily approach to increase productivity to increase profits , because there is some capacity plans .

因为产能是有一定计划的，所以不能随意地以增加产能的方法来增加利润。

Simulation shows that compared with Turbo system , this system can not only approach Shannon bound nearer , but also improve the utilizing rate of frequency , so can widely utilize in modern mobile communication system .

计算仿真表明：其性能不仅比Turbo码系统更接近Shannon限，而且提高了频带利用率，可以广泛地应用于现代移动通信系统中。

An idea of varying rotation coordinates to improve the property of chaos system is presented to solve the problem of some low-dimension chaotic systems and super-chaotic systems , which can not come approach to the state of synchronization and abbreviates synchronization time .

针对无法通过传送单一（路）信号实现同步的低维混沌系统及超混沌系统同步，以及一些混沌同步系统同步时间较长的问题，采用旋转坐标变换法对混沌系统进行改进。

But Laplacian distribution model can not be well to approach the tailing of DCT coefficients distribution which is based on the rate-distortion model and corresponding rate control algorithm have some defects .

而Laplacian分布模型在DCT系数分布曲线的拖尾处不能很好地去逼近。因而在其分布上建立的率失真模型以及相应的码率控制算法存在一定的缺陷。
