查询词典 surface noise

Firstly, through applying Hilbert-Sobolev norm to measure fidelity term, a total variation filter is used to smooth the normal vectors of the level curves of a noise image. And then, a model is constructed to find a surface which fit smoothed normal vectors.

决定这类家具安全性的关键是面与腿的连接五金件质量是否过硬，判断五金件质量时，首先要看其做工，如表面是否粗糙、开关是否自如、有没有不正常的噪声。

The results show that:(1)the low-noise source-follower circuit can be effectively used to measure the output of PVDF thin film;(2)the piezoelectric coefficient D33 of the PVDF is very sensitive on temperatures;(3)the value of D33 intensively fluctuate in initial loading stage,this means that a pre-load is needed in practice application to keep a constant piezoelectric coefficient D33 of the PVDF;(4)when the compressive load is imposed on the surface of the PVDF along a incline direction,D33 value is obvious changed with changing incline angle,and(5)the frequency bandwidth of the PVDF thin film is very wide,it is more suitable to measure strike or impact loading at various loading conditions.

结果表明：(1)低噪声源跟随电路可有效测量PVDF 薄膜输出；(2)PVDF压电薄膜的压电系数D33对温度很敏感；(3)D33值在加载初始阶段波动很大，所以实际应用中应给PVDF提供一个预压载荷，以确保有一恒定的压电系数D33；(4)当压载荷沿倾斜方向作用在PVDF 表面时，由于有剪切力作用，D33 值会随着倾斜角的变化发生显著改变；(5)PVDF 薄膜具有很宽的频响，更适用于测定不同载荷条件下的侵彻或冲击等动态载荷。

The characteristic of this series leveler iS that it has adopted two national patent technologies:group driving plate levelling machine ZL200420001176.0 and axial decelerating motor leveler ZL200520007514.6.Each top roll is driven by a set of decelerating motor.and every two lower rolls are driven by a set of dynamic system,so that the line speed of each roll iS consistent with sheet metal speed of the contacting part,and it has solved the problems existing in traditional transmission system,such as friction between sheet metal and roll surface.and mechanical interference problem in the system And the working roll adopts spherical roller bearings which have little friction resistance.so this series leveler has such advantages as high levelIing quality,Iittle noise,low energy consumption and environmental protection.compared with traditional levelers.

该系列矫平机的特色之处在于：采用分组驱动板材矫正机(ZL200420001176.0)和一种轴装式减速电机矫平机(ZL200520007514.6)两种国家专利技术，每根上辊由一套减速电机驱动，每两根下辊由一套动力系统驱动，从而使各辊的线速度与所接触部位的板料速度相一致，消除了传统传动系统存在的板料与辊面之间的摩擦和传动系统内部的机械干涉问题，同时由于工作辊的轴承均采用轧机用调心辊子轴承，摩擦阻力小，因此，该系列矫平机与传统矫平机相比，矫平质量高、噪音小、能耗低、节能环保。
