Experiments show that the performance of the new approach to the edge classification is better than that of the traditional kind in the edge accuracy. stability and the edge smooth and continuousness, except for more edges and Less noise.

实验结果显示，基于颜色恒常的照度准不变边缘分类算法，在光照颜色变化的情况下，不仅能检测出更多的边缘，噪声点更少，而且检测的边缘更准确，稳定，线条更光滑连续。

A new discrete reaching law is presented to improve the reaching process of discrete exponential reaching law.The discrete-time variable structure control system designed by this reaching law can not only weaken the chattering and control the system state approach to zero diminishingly,but also keep the basic property of quasi-sliding mode which can cross the switching surface step by step.This method improves the reaching process and enhances the control quality of the control system.

为了改善离散指数趋近律的趋近过程，提出了一种新的趋近律，利用该趋近律设计的变结构控制器，不仅能够大幅度削弱抖振，使系统运动最终趋于原点不存在稳态振荡，而且能使系统的准滑动模态保持步步穿越切换面的基本属性，有效地改善了趋近过程，提高了控制品质。

There's no magic wand you can wave and suddenly reliably change the quality of air in a region,' says Anthony Hedley, chairman of the department of community medicine at the University of Hong Kong.

香港大学社区医学系主任贺达理说，不可能像变魔术似的，挥挥魔杖就能一下子改变一个地区的空气质量，但一些运动员的健康确实存在受损的风险。

Under some conditions, we prove that random nonuniformly exponential dichotomy actually imply random uniformly exponential dichotomy. And, using the normal Lyapunov exponents, we also obtain a sufficient condition under which a random compact and invariant subset is a random forward attractor. This is a generalization of the results of Ashwin\'s.

在一定条件下，我们证明了随机非一致指数二分性蕴含着随机一致指数二分性，同时，利用法向Lyapunov指数，我们还给出了一个紧致的随机不(来源：A5cBc765C论文网www.abclunwen.com)变集能成为随机吸引子的一个充分性条件，推广并改进了Ashwin的一些结果。

What is the secret mesmerism which friendship possesses, and under the operation of which a person ordinarily sluggish, or cold, or timid, becomes wise, active, and resolute, in another's behalf?

友谊究竟有什么催眠的力量，能使本来懒惰、胆小、不热心的人给别人办事的时候忽然变得头脑灵活、做事勤快、意志坚决的呢？

Asking for behavioral help means that the one who asks has already shifted the problem from the mind to the body, in adherence to the ego's strategy of mindlessness that ensures that the decision-making mind will have been rendered impotent.

要求行为上的帮助，意味着请求的这个人已经把注意力从思想转移到了行动，接近了小我那试图使你神智不清的陷阱，使得能做出决定的那个思想变得软弱无力。

We use the single Fuzzy Control to control algorithms , adopt the traditional one-chip computer temperature control system, temperature of bed is it control to go on to smeltery electric heat, in order to is it work systematic dependability and security to improve, achieve the with high efficiency , high-standard goal.
