变均匀

This paper discusses the pulse-width modulation switch sequence of arbitrary-number-level inverters, and proposes a switch sequence with loss balance of power electronic devices.

讨论任意电平逆变器脉宽调制(pulse-width modulation，PWM)序列，提出一种电力电子器件损耗均匀分配的序列方式。

By the same token, any light reaching the surface of the object will have a reflection, if the plane is a rugged, light scattering in all directions will be lost; if the plane is smooth, then we can certainly see the direction of the reflected light .

而鞋油中有一些小颗粒，擦鞋的时候这些小颗粒正好可以填入皮鞋表面的凹坑中。如果再用布擦一擦，让鞋油涂得更均匀些，就会使皮鞋的表面变得光滑、平整，反射光线的能力也加强了。

ABSTRACT The diffused phase transition and frequency dispersion of Pb-based complex perovskite relaxor ferroelectrics of PZN, PMN etc. were studied by the measurements of spectum of dielectric permittivity with temperature at different frequencies as well as by the means of differential thermal analysis and ferroelectric hysteresis technique. It was found that there are various polarization relaxors which cause DPT characteristics.

本文利用介温谱的测量，差热分析和电滞回线对以PZN，PMN为代表的铅系复合钙钛矿型弛豫铁电体的相变弥散和频率色散性等弛豫特性进行了分析研究，对产生弛豫的根本原因提出了新的看法，认为这类材料的DPT特性并不是一种由成份及结构不均匀的统计分布所造成的&准&弛豫现象，而是由材料本身弛豫机制所致。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
