At present, the strong ground motion records are still in processing and can not be used in studies. However, earthquake intensity isoseismal, especially in near source region, as a macroscopic description of distribution of strong ground motion, shows the relativity with earthquake source process in some extent.

汶川地震后，虽然目前还没有得到完整的强震记录，但是作为震害宏观描述的地震烈度，在一定程度上反应了汶川地震近断层地震动与震源过程之间的相关性，如近断层地震动的方向性效应和上盘效应。

I tested them for the 3D shape and the histogram can be perfectly fitted by Laplace distribution. This is also true for most of the natural images.

但噪声由于不具备方向性的特点，所以只在某几个方向上才存在，这样消噪起来很有力。

Teaching reforms in colleges and universities lave close relationship with quality education, life-long physical education and modern education.

The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.

其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏，以有方向性的杂交和变异加速和调节搜索，同时杂交和变异作用在不同层面上使搜索在整体上均匀化，通过遗传系统里的并行竞争提高整个群体的生存适应力，从而达到整体优化的目的。

Laser, rising in early sixties of 20 century, has affected many fields because of its homochromy, high lum and straight direction.

激光是20世纪60年代初期兴起的一项新技术，由于其具有单色性好，高亮度和方向性好的特点，对各个技术领域产生了巨大的影响。

objective to study the intensity of magnetic field on a special meridian magnetic applicaˉtion.methods a special meridian magnetic application is found the variations of the intensity of magnetic field when it is in vitro,nipped by fingers and stuck on skin of meridian and non-meridian.results the variation of the inˉtensity of magnetic field and the difference of the two poles have a statistical significance when the special meridian magnetic applicationon straight line and interval10mm compares to on other conditions above.conclusion owing to a definite directivity of the magnetic field gradient is produced when the magnetic application on the meridians,it is hopeful to carry out the effects of the tonic and vent by acupuncture.

目的 研究循经传感磁疗贴的磁场强度变化。方法一种特制的磁疗贴，在体外、指捏、敷贴于皮肤表面的经络走行和非经络走行区时所测得的磁场强度变化。结果当该磁疗贴直线排列，间隔10mm时，与单独磁疗贴的初始相比，磁场强度发生明显变化，且具有两极差异；敷贴于皮肤经络走行区，与体外及非经络走行区相比，磁场强度变化显著，尤其在手阴经的走行区域，具有显著的统计学意义。结论该磁疗贴在经络走行线上形成的磁场梯度，具有明确的方向性，有望实现针刺产生的补与泄的作用。
