ansys 分析 圆环的受力:一个的圆环,受一对过直径的集中 应力, 作用下发生1mm的压缩量（如图所示）。已知材料的弹性模量E＝2.0GPa，泊松比为0.3。用平面应力单元PLANE82分析圆环内部的应力分布情况(ansys analysis by the Circle : A Circle and the one across the diameter of the concentrated stress, occurred under 1 mm compression volume (as shown). Known material elastic modulus E = 2.0GPa, Poisson's ratio of 0.3. Plane stress analysis modules PLANE82 Circle internal distribution of the stress)

EZW算法的matlab代码，希望对大家有用(EZW algorithm matlab code, everyone would like to be useful)

Huffman 编码是第一个实用的无损压缩编码技术，经过了多年的不断改进，已经形成了系统的理论和方法。目前主要有两种类型的Huffman编码方式，即静态Huffman编码和动态Huffman编码。Huffman编码有着广泛的应用，但是不再是压缩算法的全部，而是被当作最终的编码方法。(Huffman coding is the first practical lossless compression coding technology, after years of continuous improvement, has formed a system of theories and methods. There are currently two types of Huffman encoding, namely, static and dynamic Huffman coding Huffman coding. Huffman coding has been widely used, but the compression algorithm is no longer all, but rather be treated as the final coding.)
