Celerity is the soul of warfare兵贵神速。It developed very quickly for precision celerity and big capacity.因具有准确、快速、大信息量等特点而发展迅速.Shallow Seismic Refraction Survey is one kind of celerity, effective and economic means in engin...
角θ称为Z的幅角.The angle θ is called the argument of Z.利用集合来定义辐角函数,研究幅角函数的存在性、连续性、可微性等性质.Argument functions are defined by set and its existence , Continuity and differentiability are discussed.最后给出了基于视差梯度约束和边缘幅角约束的快速边缘匹配算法.At...
This suggests destocking by refiners, not a fall in underlying oil demand.这说明,炼油商们在压缩库存, 而并非基础石油需求下降.Refiners chugging along at a low utilization rate of about 80 %.炼油厂仍维持着80%左右的低开工率.Importing refined oil will lead to th...
