格子玻尔兹曼 圆柱绕流 Python编写(lattice boltzmann flow around a cylinder, using Python. very fast because of numpy library)

改程序是计算出金属表面等离子体直波导的有效折射率随波长和传输长度随波的两色散曲线，另外给定Drude-Lorentzia模型参数给定后，还可以求解介电常数以及画出相应实部和虚部的曲线(This programer is used to calculate Ag relative dielectric constant accroding to the Drude-Lorentzia and sovle the transcendental equation for even illumination. At the same time,it can draw the diagram of relationship between the dispersion curve and the Transmission with the length. )

Finding special triples of the form (n, n + 1, n + 2) Write a program that finds all triples of consecutive positive three-digit integers each of which is the sum of two squares, that is, all triples of the form (n, n + 1, n + 2) such that: • n, n+1 and n+2 are integers at least equal to 100 and at most equal to 999 • eachofn,n+1andn+2isoftheforma2+b2.(Finding special triples of the form (n, n+ 1, n+ 2) Write a program that finds all triples of consecutive positive three-digit integers each of which is the sum of two squares, that is, all triples of the form (n, n+ 1, n+ 2) such that: • n, n+1 and n+2 are integers at least equal to 100 and at most equal to 999 • eachofn,n+1andn+2isoftheforma2+b2.)
