查询词典 magnitude

The electric parameters of the sample such as dielectric constant, spontaneous polarization magnitude and orientation play an important role in the image contrast.

样品的电学性能参数如介电常数、自发极化强度和取向等的改变对电声像衬度的来源起着决定性作用，对电声成像理论提出了新的解释。

The output of electron acoustic signal in the ferroelectrics is calculated on the basis of their piezoelectric properties. The results show that the magnitude of electron acoustic signal not only related with beam currents, beam power and modulation frequency, but also with sample properties especially electric parameters such as dielectric constant and spontaneous polarization.

本文首次以典型的铁电BaTiO〓材料为试样，从其具有的压电性出发，推导了这类材料的电声信号理论表达式，结果表明电声信号的大小不仅与实验参数如入射电流、入射电子能量以及调制频率等有关。

To improve the segmentation effection and efficiency, we fulfill the following work:There is an obvious difference between General Fuzzy Operator and other edge detection which based on edge magnitude.

本文在提高图像分割质量和效率方面做了以下几个方面的工作：基于广义模糊算子法的图像边缘检测与其它基于边缘强度依靠导数的边缘检测法明显不同，具有计算量小，检测到的边缘精度高等特点，但是GFO算法中的关键参数需经验、人为确定，影响了该方法的检测效果，限制了其在实际中的推广应用。

The derivation course and the discrete scheme of the first model-Perona-Malik model have been expatiated on emphasis. One item of the P-M model is omitted in the P-M's discrete scheme, and the gradient magnitude is replaced by the absolute value of difference quotient.

Perona-Malik给出的离散格式是一种显式离散格式，这一格式的连续形式省略了原模型中的一项，且用差商的绝对值代替了梯度模。

This formula first scales the magnitude to become the average arc length, and then it scales again to account for the other directional derivative.

这个公式首先将量级缩入成平均弧长，然后又在另一方向的导函数上进行缩放。
