当成分起伏的“方向性”和“程度”满足形核的热力学条件时，相变驱动力增加，可以促使钢液形核。
When unstable thermal conditions are satisfied with the constituent fluctuations of "correct direction" and "degree", phase transformation driving force is raised and nucleation is promoted.
该算法以低通滤波算法估计背景中的低频成分，及图像局部方差估计背景起伏，来计算出局部自适应的目标检测判决门限。
The algorithm adopts low pass filter to estimate the background and calculates the standard deviation to estimate the fluctuation of background to get the local adaptive detection threshold.
笔者以形核热力学为基础，讨论了外来成分起伏对钢液形核的影响，并通过实验进行了验证。
Based on thermodynamics, effects of constituent fluctuations on nucleation is studied and testified in this paper.
研究结果表明，在钢液中造成一定方向和程度的成分起伏，可以促进钢液生核，从而增加铸坯中等轴晶数量。
The experiment results show that special constituent fluctuation in certain direction and with enough strength in liquid metal can promote nucleation in liquid metal and increase...
