If, to use their own domestic production of import substitutes the same welding machine dedicated welding machine, robots with the use of complementary and preserve their function unchanged, it would not only greatly reduce the use of industrial robots cost, can also enhance robot peripherals in China.

如果，能使用国内自己生产的同等电焊机替代进口的专用电焊机，与机器人配套使用而保持其功能不变，将不仅大大降低使用工业机器人的成本，也可提高机器人外设的国产化。

Complete chiral induction from enantiopure-DPEN to achiral bisphosphine ligand 3a was observed in solution, with the complex adopting a single, stable and non-fluxional (even at 70 ℃) configuration.

光学纯-DPEN在溶液中对非手性双膦配体3a产生完全的手性诱导，形成构型单一的稳定RuII络合物，即使在70°C下构型仍保持不变。

One of Hutchinson's basic results is: If {S〓,…, S〓} is a family of contract operators on a complete metric space, then there is a unique nonempty compact set K, such that K=〓.

Hutchinson的一个基本结论是：对于完备距离空间上的任一族有限压缩映射{S〓，…，S〓}，存在唯一的不变非空的紧集合K，〓。

The increment of the horizontal component of the force together with no change in direction makes the roll system steady.

保证辊系稳定的有效办法是让工作辊轴承座与支承辊轴承座之间受一个方向始终不变的水平力。

The two clauses can be reversed in a conditional sentence with no change in meaning .

在条件句中两个分句可以颠倒而句意不变。

With the reform step of the commercial bank has expedited, new institutional and constant renew from time to time, conditionality system is step by step to perfect, the management of the fixed assets is request more and more.

随着商业银行改革步伐的加快，新制度的不变更新，相应制约机制的不断完善，对固定资产的管理提出了新的要求。

Experimental results prove that extracted features using phase congruency is invariant to image illuminance and noise.

实验证明，相位叠合提取特征对图像的照度以及可能出现的噪声是不变的。

First, we extract the illuminance invariant feature using the phase-only reconstruction and the phase congruency analysis.

该方法首先利用单纯相位谱重构和相位一致性分析实现光照不变特征提取，然后利用PCA方法实现人脸图像的降维表示，降低识别所需的计算量。

It was the first time political power, as represented by coinage, was connected to a set of unchanging universal ideas rather than a person.

这是人类历史上第一次，硬币体现的政治权力与一整套恒久不变的普遍观念相联系，而非与任何个人
