Characteristic data have been worked out, including the maximum Lyapunov index λ, fractional dimension D, lacunarity Λ and eight energies of various frequency bands. After being normalized, they can function as the characteristic vectors. Then, they are transmitted into an artificial neural network to perform pattern recognition.Starting from the mechanism of ultrasonic generating, initial ultrasonic pulses are calibrated. A stylish discharge source is directly coupled with the ultrasonic sensors, and work out actual discharge magnitude.

The working load of engin e in plowing can be taken for stable and normal random load whose power spectrum peak value is below 2 Hz. The working load of engine in rototilling contains bo th periodic element whose fundamental frequency is rotating speed of the blade s haft and normal random load of which the parts of energy centers in fundamental frequency and others are distributed over wider frequency band.

证实了犁耕作业发动机的载荷可以认为是平稳的正态分布的随机载荷，其功率谱曲线的谱峰在低于2 Hz处；旋耕作业发动机的载荷是兼有随机成分和周期成分的动态载荷，其中周期谐波的基频为刀轴转速，随机成分一部分能量集中于基频以内，部分分布于较宽频率范围。

As a Chinese old saying narrates:"clumsy birds have to start flying early", in my view, the more gifted a designer is, the more early he or she shall start to rise in order not to fall short of his or her born talents. Many ingenious designers make no achievements in the end because of his or her excessive self-contentedness, which is a negative example of another Chinese idiom: Fortune always appreciate a hardworking person.

平稳的心态是做任何事情的关键，中国的一句老话"笨鸟先飞"，我觉得越是资质优秀的设计师越应该先飞，不要辜负父母给你的优秀基因，有很多资质聪慧的设计师满足于自身的优势而最终一事无成，还是中国的一句老话"天道酬勤"。

During scrying - one gazes steadily into the scrying surface (feel free to blink or allow your point of focus to wander a bit; this is not a method of self-inflicted torture).

在占卜的过程中-人必平稳的凝视水晶球的表面（稍微放轻松，让你的注意力稍稍发散；这并不是一个折磨本性的方法）。

JIT in automobile industry require a rapid response of automobile accessory enterprise. In order to cover the peak demand and eliminate uncertain factor in production and gain a higher customer satisfaction rate researching of safety stock becomes very important in this industry.

This paper introduced the market development trend of vanadium products(include ferro-vanadium and vanadium oxide).

介绍了钒产品的市场发展趋势，重点从2005年的45万元/t的钒铁历史高价开始分析，到近两年的市场平淡、平稳的原因，并且对从中反射出来的规律进行了总结。

This routine is a series of moves which must be done smoothly to create illusions of knotting the ring on the rope without letting go of the ends of the rope, removing the ring by apparently visibly penetrating through the knot, then finally removing the knot itself from the rope.

这个流程中的所有动作需要快速且平稳的完成，从而产生圆环被粗棉绳牢系的视觉幻象。接着环将从绳结中逃脱，最后绳结也会从棉绳上脱逃。周围吹拂着微风，轻抚着我的头发与手指，穿越夜晚边缘的暗影，直到所有星星沉寂。。。
