Numerical results show that the sliding structure using semi - active control not only has good vibration isolation effect , but also has less maximum slippage and less residual base displacement 对实例计算结果的分析表明,半主动控制下的滑移隔震结构不但具有较好的隔震效果,而且能有效地减小基底的最大滑移量及残馀位移。
Preparation of steel substrates before application of paints and related products - visual assessment of surface cleanliness - preparation grades of previously coated steel substrates after localized removal of previous coatings 涂油漆和有关产品前钢基底预处理.表面清洁度的目视评定.局部去除原有涂层后钢基底的处理等级
The transmittance formula included most of the film and substrate parameters , which affected the transmission spectra , was given in a simplified form , and it was rigorously derived from electromagnetic theory 用极其简单的形式给出了经电磁理论严格推导出来的透射率公式,该公式包含了影响透射光谱的大部分薄膜和基底的参数。
We made good use of the industrial computed tomography ( ict ) , scanning electronic micrograph ( sem ) and imaging analysis assemble to investigate the inner and surface fine structures of the cathode in quality and quantity 3 )采用ct微焦点系统等检测手段对阴极基底的内部和表面微观结构进行了定量和定性的分析,有望成为控制阴极基底的质量重要手段。
Therefore the method and the equation developed in this paper to compute maximum scour depth is applicable and provides a reliable and convenient way to access maximum scour depth in engineering 该公式与现有公式比较,概念清晰、型式简单,采用该公式计算大尺度直立圆柱建筑物基底的最大冲刷深度可给出令人满意的结果,可供实际工程中估算最大冲刷深度。
