查询词典 sampling fraction

Methods The human pancreatic cancer Panc-1 cells were exposed to a single fraction of high-doseγ-ray radiation either with CMNa or under hypoxic condition. The percentage of dead cells was detected with a multiwell plated reader, and fluorescence intensities of propidium iodide were measured before and after digitonin treatment.

It is a knowledge-based potential and consists of two characteristics: protein main chain polar fraction and dihedral angles.

利用蛋白质主链的极性分数及主链二面角为参量，构建了一种基于蛋白质结构数据库的势函数。

At 2years after OPBPV,right ventricular end-diastolic volume and end-systolic volume were still significantly bigger than control group (P ＜0.01) in all patients but right ventricular ejection fraction was normal,RVEDV dilatant rate correlated very well with DB/Dp ratio significantly.

RVEDV较未手术组的扩大率与球/瓣比间有非常显著相关(P＜0.01)，RVESD扩大率与球/瓣比间有相关趋势，但球/瓣比与术后即时、3月、＞2年的ΔP↓率间无显著相关(P＞0.05)。

However, to establish global convergence for these latter methods, one must enforce either sufficient decrease conditions (the Armijo-Goldstein-Wolfe conditions)or a fraction of Cauchy decrease condition - all of which rely on explicit numerical function values, as well as explicit approximations to the directional derivative at the current iterate.

但是，为了保证后面方法的全局收敛，必须有足够的减少条件（Armijo-Goldstein-Wolfe条件）或者部分柯西减少条件——它们全都依赖于外在的数值函数值，就和在当前迭代逼近方向导数一样。
