A Token is generally a random string of letters and numbers ( but not limited to ) that is unique, hard to guess, and paired with a Secret to protect the Token from being abused. 令牌一般是字母和数字(不限于)组成的随机字符串,它是唯一的,难于猜测的,通过密钥来保护它不被篡改。
For the numerical study the random choice method is used in a much improved and extended form that include the more accurate initial guess of p to start the iteration process, the solution of Riemann problem and the much improved iteration method. 文中采用了一种改进了的随机选取法,包括初值的选取,Riemann问题的解及迭代方法的改进。
