Through comparison and analysis, the major different factors of the casualties for these two extremely similar earthquakes occurred in Yunnan are found out. The early-warning foreshock (or short-impending prediction) is the most important factor in reducing the casualties. The area size in high intensity is the most vital factor to casualty.

Vectorgraph can be converted to a bitmap, but in turn bitmap converted to vectorgraph technical comparison difficult to achieve, a lot of graphic design software that support the use of pixel figure converted to vectorgraph, a general description of the software for free vector function realization, so that we can on the basis of vectorgraph to do the editing, but this kind of conversion sometimes is time-consuming, and sometimes does not achieve the expected results, it is generally used for relatively simple bitmap, or you would like some special effects.

矢量图可以转换成位图，不过反过来把位图转换为矢量图技术上比较难实现，很多图形设计软件都支持将像素图转换成矢量图性，一般可用矢量软件的描摹功能实现，这样我们就可以在矢量图形的基础上再做编辑，但这样的转换有时候会很耗时，有时候并不能达到预想的效果，一般用于比较简单的位图，或者想要表现一些特殊的效果。

The constant current coulometry as a primary method is recognized in international. Based on Faraday's law of electrolysis, it has been successfully used to determine purity of arsenic trioxide.

Based on the fundamental theory of impulsive differential systems, employing Green formula, Gauss divergence theorem, Jensen inequality and Gronwall-Bellman inequality with impulse, we discuss the oscillation of impulsive partial differential systems by adopting reduction to absurdity and the stability in via of comparison theorem, respectively. Especially, we take an in-depth study on the oscillation of neutral impulsive parabolic systems and the stability of a class of nonlinear impulsive partial differential equations and obtain some useful conclusions.

In this paper, three methods for color image retrieval have been presented: hypercomplex SVD image retrieval, combination of hypercomplex convolution filter and hypercomplex SVD image retrieval and hypercomplex matrix correlation image retrieval. We made comparison among these hypercomplex-methods, and compared them with the traditional image retrieval methods. Experiment results showed that the hypercomplex-methods we presented in this paper could well conquer the problems existed in traditional image retrieval methods, and their retrieval results are much better. Meanwhile, this paper presented a new color image quality assessment based on hypercomplex SVD. It is a novel color image quality assessment that can be used as a graphical or a scalar measure to predict the distortion introduced by a wide range of noise sources. It reliably measures the distortion not only within a distortion type at different distortion levels, but also across different distortion types.
