Some results on flat dimension of modules and SF-rings 模的平坦维数(FD)和SF-环的几个结果
By the physical simulation on the upset of quadrangular section billet between flat platens, the influence of billet's dimension on the stress state within the forming body has been investigated qualitatively. 通过对矩形截面毛坯在平板间镦粗的物理模拟,定性地研究了毛坯长度尺寸对变形体内部应力状态的影响。
The end image of tubular propellant charge was obtained by a flat scanner, and a high precision digital test to the dimension of small tubular propellant charge can be realized through a series of image technical transformation to photo obtained with computer. 利用平板扫描仪获取装药药管端面图像,经计算机对图像进行一系列技术处理,实现了对小型推进剂管状装药药形尺寸的高精度数字化检测。
The pores, most of which are flat in shape, are typical narrow void, high fractal dimension and high pore-throat ratio. 孔隙结构特征表现为喉道小,分形维数高,孔喉径比大,弯曲度大且大多呈扁平形状。
The absorptivity of flat metal plate is determined by coat absorptivity and that of the surface porous metal plate is by not only the coat absorptivity but also the porous ratio and the dimension of the hole. 光滑金属板的作为吸热板芯时,其吸收率取决于涂层的吸收率,而用表面多孔板作为吸热板芯时,其吸收率则取决于板孔隙率和孔尺寸与涂层的吸收率。
