Methods of exploring the real number roots of a real coefficient polynomial function are procedurally given. 摘要较程序化地给出了实系数多项式函数实数根的求法。
The vertical and the horizontal coefficient of consolidation can be adequately modeled by either a lognormal distribution or a gamma distribution. 固结系数的概率分布一般为对数正态分布或伽玛分布。
