Infection assay in vitro showed that overexpression of p78 / 83 had n ' t any evident effect on the virus growth and viral assemble . it is notable that the fusion protein can be assembled to virions . via actin dissemination in vac - orf9 - gfp infected cells , p78 / 83 - egfp might colocalize with actin 对vac - orf9 - gfp感染sf21细胞作电镜时相切片分析，结果表明，表达p78 83 - egfp融合蛋白的重组病毒，对病毒粒子的形态发生没有明显可见的影响。
For the cloudy region , the pixel values were substituted by the image data of same period and close time after being calculated . the calculation was based on the correlation of clear sky image with cloudy . at last , clear - sky day - time - averaged lst image of guangxi were made 再对该原图进行云剔除，并选择与原图时相最接近的实况样本，用统计回归方法进行相幅间的数值补偿，由此剔除原图中的云区，最终制作生成广西全境白天千米空间尺度的lst平均图。
Four experiments on the application of sar data to extract forest resource information were carried out : ( l ) use sar data only ; ( 2 ) pca transformation was carried out to tm data , then , the top three pcs were combined with sar magnitude image and sar texture image ; ( 3 ) all tm bands ( tm6 excluded ) and sar data were combined together , and then pc transform were adopted ; ( 4 ) sar data ( 2000 ) were merged with tm 3对sar图像，采用四种方法进行林业信息提取研究：一是单独利用sar图像进行提取，二是取tm图像主成分变换后的前三个分量、两个时相sar图像的灰度图像及纹理图像组合进行提取；三是将tm的6个波段与两个时相的sar图像主成分变换进行提取。
In the paper , ten satellite photographs from 1979 to 2001 are studied to contrast and analyze the distribution area of the coastal salt marshes in different period using the software of mapinfo 5 . 0 . it discusses the influence factors and basic laws of the coastal salt marshes along the unerosinal coast in jiangsu . at the same time , it also discusses the recover and rebuilding processes of the coastal salt marshes after the tidal flat was reclaimed 本文采取1979年2001年间共10个时相的盐城幅卫星影象，结合软件mapinfo5 . 0 ，采用卫片配准? ?数字化? ?叠合分析的方法，对历年来各个时相卫片上反映出来的海岸盐沼的面积大小及分布范围进行对比研究，初步探讨了江苏非侵蚀海岸盐沼消长的影响因素与基本规律，并探讨围垦以后盐沼的恢复与重建。
It is necessary to control the mechanical stimuli precisely in the studies of cardiac mechano - electrical feedback ( mef ) . in the present study a ventricular pressure - clamping system has been developed , which can be applied to isolated - perfused rabbit hearts . controlled by a computer , this system not only can make the left ventricle follow a command defining the same pressure wave as that during a beating cycle under physiological condition , but also deliver mechanical stimuli with a proper waveform to the ventricle at a particular time phase . this system integrates multiple functions , including perfusing , pacing , recording of electrocardiogram and monophasic action potentials , and clamping and measuring of ventricular pressures in isolated - perfused hearts . thus , it is a distinct system for investigating the phenomena and mechanisms of cardiac mef at organ level 在心脏机械电反馈的研究中准确控制机械刺激是非常重要的.本研究室构建了一套适用于离体家兔心脏的心室压力钳系统.该系统通过计算机控制压力钳,不仅能模拟正常生理条件下左心室的压力波形,还能在心室活动周期的特定时相、以适当波形对心室施加机械刺激.该系统集心脏灌流与起搏、表面心电图记录、单相动作电位记录、心室压力钳制与测定等多种功能于一体,特别适用于器官水平上观察机械电反馈现象并探讨其机制
