On the other hand, the magnitude and difficulty of the trust to which the voice of my country called me, being sufficient to awaken in the wisest and most experienced of her citizens a distrustful scrutiny into his qualifications, could not but overwhelm with despondence one who (inheriting inferior endowments from nature and unpracticed in the duties of civil administration) ought to be peculiarly conscious of his own deficiencies.

我唯一敢祈望的是，如果我在执行这项任务时因陶醉于往事，或因由衷感激公民们对我的高度信赖，因而受到过多影响，以致在处理从未经历过的大事时，忽视了自己的无能和消极，我的错误将会由于使我误人歧途的各种动机而减轻，而大家在评判错误的后果时；也会适当包涵产生这些动机的偏见。

In space their shape, magnitude, and relation to one another are determined or determinable.

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

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。
