METHODS Left ventricular ejective fraction, regurgitant velocity and regurgitant direction were examined by color Doppler echocardiography in 151 patients with medium mitral regurgitation. The results of LVEF, regurgitant velocity and regurgitanting gradient were compared between patients with and without murmur grope.

随机选择151例经超声心动图检查，显示有中度及中度以上二尖瓣返流的患者，根据彩色多普勒血流显像分别测定LVEF、返流速度等超声参数，比较其在杂音组及无杂音组间统计学差异，分析其对听诊的可能影响。

All indexes of systolic function (systolic peak velocity Vs、systolic peak displacement Ds、 and ejective fraction of left ventricle EF)were examined against baseline, at the end of 60 min ischemia and after 180 min reperfusion.

实验犬分别于缺血前基础状态、缺血60分钟、再灌注180分钟时进行心脏收缩功能指标参数，即收缩峰值速度、收缩峰值位移、左室射血分数测量。

Eldon S. Hendriksen and Michael van Breda, the authors from Southern Methodist University of a leading text on accounting theory, have said that annual depreciation, one kind of allocation, is simply a fraction of the total cost and is not necessarily related to occurrences within the year, so it has no real-world connotations.

艾尔敦第亨德里克森和Michael Van Breda公司，作者从南方卫理公会大学的领导的案文对会计理论，有说，每年折旧，一种分配，只不过是一小部分的总费用是没有必然关系发生的内部今年，所以它没有现实世界的内涵。

Results show that the best value of w is 7~10% and 5~7%, i is 0.08~0.2 A/cm^2 and 0.03~0.05 A/cm^2 respectively, during the electrolysis fluorination of pyridine and tributylamine; the addition of N-butyl mercaptan into the organic mixture can stabilize electrolysis process with its mass fraction 15~20% at best; impulse current polarization work status of low load is helpful to the electrolysis process and reduces corrosion rate of anode; electrolysis temperature is suitable at 0~20℃; electrobath can use electrolyte inner circulation structure, exterior circulation structure or blending structure.

结果表明：吡啶和N-三丁胺电解氟化的最佳值w分别为7%~10%和5%~7%，i分别为0.08~0.2A/平方公分和0.03~0.05A/平方公分；有机混合物中添加N-丁基硫醇可稳定电解过程，其质量分数最佳为15%~20%；采用低负荷的脉冲电流极化工况有利电解过程，降低阳极的腐蚀速度；电解温度0~20℃为宜；电解槽可采用电解液内循环、外循环结构，或其混合结构。
