By mechanical test of the steel strip and simulation of strip deformation in tension leveling using finite element method,characteristic features of the strip were obtained,such as;high yield stress,high yield ratio and low plastic elongation as the basic reason of difficulty in tension leveling and shape control.

通过对全硬钢的力学性能的测定和拉矫变形行为的有限元仿真，发现屈服应力大、屈强比高以及断裂时塑性延伸小等特性是造成镀锌后全硬带钢拉矫困难和板形难以控制的根本原因。

Their first priority is to stop using the "clamshell" packaging - you know, that hard plastic that is impossible to open and always way to big for the item.

我不确定。他们的首要任务是停止使用"硬式塑膜"包装——要知道，那些硬塑料实在）是很难打开的，而且它们对于所包装的东西而言，往往太大了。

The problem of misusing of coating categories that exists in current super-hard abrasive coating/deposition and their correlative product is analyzed.This article is divided into two parts. The methods, performances and applications of electroplating and chemical plating Ni, Cu and plating metal which partly uses physical means, and some coati...

本文由于篇幅问题分为两部分，在中主要介绍了超硬磨料表面电镀和化学镀镀覆Ni、Cu及部分利用物理方法镀覆Ti等金属的方法、性能及用途；在中介绍了超硬磨料表面镀覆Ti等强碳化物形成元素及刚玉等方法、性能及用途。

By the method, we can obtain the convergence factor of each subband according to every subband statistical character driven by a standard Gaussian white noise. The hard threshold of every directional subband of each scale is determined by modifying the 3σ(or 4σ) rule in terms of corresponding effect factor.

该方法根据标准高斯白噪声作用在每个子带上的统计特性，得到每个子带的收敛因子；使用该收敛因子对标准的3σ(或4σ)准则进行修正来确定不同尺度不同方向子带的硬阈值；并在轮廓波域进行子带硬阈值处理之后，使用自适应维纳滤波进行后处理。
