the region of convergence的意思|示意

The distance ratio iteration method is a new fractal rendering method which can construct complex inner structure in the convergence region of complex mapping.

距离比值迭代方法是一种新的分形绘制方法，可以在复映射收敛区域绘制出复杂的自相似结构。

The shape of regurgitant jets in 30 patients with eccentric mitral regurgitation showing now convergence region (FCR) was observed.

观察30例显示血流会聚区（FCR）的偏心性二尖瓣返流患者的返流束形态，发现均为附壁细长束。

Aiming at the shortcomings of trust region method, we proposed an algorithm using negative curvature direction as its searching direction. The convergence of the algorithm was given.

针对模型信赖域方法中搜索方向存在的不足，提出了按负曲率方向进行搜索的模型信赖域算法，并证明了算法的收敛性。

Flow convergence region, which was located in the left ventricular sides of mitral valve, was displayed in 63%(33/52)of physiological MR and 100%(87/87) of pathological MR.

结果发现：33／52（63％）例生理性二尖瓣返流和87／87（100％）例病理性二尖瓣返流可于二尖瓣左室面显示血流会聚区；

Because they have same convergence region, sum of series and combinational twin identifies was obtained using the method of substitution.

它们有相同的收敛区间，应用代入法求出它们的级数和，从而获得孪生组合恒等式。

It was concluded that M-mode and two-dimensional color Doppler flow convergence region could be used to quantificate the area of mitral stenosis accurately.

结果表明，M型彩色多普勒血流会聚法与二维彩色多普勒血流会聚法在检测二尖瓣狭窄瓣口面积方面基本可靠，但两者的准确性无显著差异。
