In order to improve the diagnostic precision of cardiac disease and understand the effect on the body surface ecg of myocardial cell and ionic activity , the experimental method can be used , but it needs long time , high cost and big fatalness , so ca n ' t make people content 为了提高心电图诊断水平,深入了解心肌细胞及其离子活动对体表心电的影响,可以采用人体或动物实验的方法,但是,这些方法存在周期长、代价高、危险性大等问题,很难令人满意。
Does allogroomiog serve a hygienic function in the sichuan snub - nosed monkey to test the hygienic functional hypothesis of allogrooming in the sichuan snub - nosed monkey , we analyzed the distribution of such behavior over the body surface of individuals in the west ridge troop in the yuhuangmiao region of qinling mountains , shaanxi province , china . based on 113 days of observations of the troop , 293 allogrooming bouts were obtained by focal - animal sampling . we divided the body surface of the monkeys into 17 areas 第二章川金丝猴的理毛行为是否符合卫生功能应用目标动物取样法，在113天的跟踪观察(有效观察时间351小时)的基础上，收集了293个相互理毛回合( bout )的数据，对秦岭川金丝猴( rhinopithecusroxellana )玉皇庙西梁群个体间的相互理毛进行了分析，检验相互理毛是否符合卫生功能假说( hygienicfunctionhypotheses ) 。
In this method , the interpolation polynomial is related to several cells nearby , so the body surface is smooth , the potential function and its derivative is uninterrupted on the whole surface . moreover , because the interpolation based on b - spline is very accurate , it can enhance the efficiency of calculation and make a good numerical result by coarse gridding 在这种基于b样条的面元法中，由于插值多项式涉及附近的几个单元，而不像一般的面元法只限制在一个单元内，因此物体表面是光滑的，速度势函数及其导数由于采用样条函数表达，在整个物体表面也是连续的。
