And the accuracy of using point-slope method and slope-proportion method to predict triaxial dynamic modulus was evaluated.
对SMA-13,Sup-20和Sup-253种沥青混合料进行了不同温度、围压和加载频率下的动态模量试验,并对利用点-斜率法和斜率-比例法(由中间点和由边缘点)预测三轴动态模量的效果进行了研究。
An improved method which measures frequency through the slope of zero based on the cross-zero detecting is presented.
因此提出了一种改进的过零检测算法:零点斜率测频法。
Then,it completes the detection of transistor s pins by checking area and find out the position of the transistor by checking slope of center.
先通过对目标图像的预处理和阈值分割完成图像的前期处理,然后通过面积法实现了集成块管脚的定位和检测,再用中心点斜率法完成了对集成块姿态的检测。
