Polyethylene-nanocomposites with CaCO3-weight fractions from 0 to 15 wt.% were prepared by in-situ polymeriza- tion with Me2Si(Ind)2ZrCl2/MAO metallocene cataly
Numerical exercises are presented on the thermally induced motion of internally heated beams under various heat transfer and structural boundary conditions. The
3D and 2D closed form plate models are here applied to static analysis of simply supported square isotropic plates. 2D theories are hierarchically classified on
（一）发病情况河南省新乡市某肉牛场从吉林引进6～8月龄的杂交肉牛30头，2个月后，有1头牛发生不食、粪便带血。按出血性肠炎进行治疗，效果不好，之后又发病4头。经临床检查和实验室检查，
A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluorescence (LIF) in an optically participating spray
针对红外图像中的脉冲噪声问题以及传统滤波算法的不足,提出了一种自适应直觉模糊滤波算法.该算法利用直觉模糊集理论在处理不确定性问题中的优势,将图像中各个像素点改由一对隶属度函数和非隶属度函数自适应地标定,然后采用修改后的直觉模糊熵定义自适应地确定各像素点的权值以完成滤波.给出了该算法的具体步骤,仿真结果表明:当脉冲噪声密度较大时,采用该算法可有效地滤除噪声;即使当噪声密度很大时,在数学形态学方法的辅
