医学专家称，温水游泳池温度在30摄氏度左右，适合精子生存，在这种化学环境下精子通常最多只能存活1到2个小时，如果还能适时让游泳的女性怀上身孕，这种概率简直比中彩票大奖还要低。

Indices, including average line loading, average line flow limit per MW served, line investment ratio are proposed to quantify the stress level of the system, while the probability distribution function of fractional load shed and total failure components, cascading failure frequency, and risk are used for the risk analysis of cascading blakcouts.

论文提出了网络利用率、单位平均投资和线路投资比等指标，对系统的临界水平进行量化；并采用连锁故障灾难度的概率分布函数、连锁停电事故频度和风险等指标分析电力系统的连锁故障风险。

What scientists call "the fraternal birth order effect", the fact that each successive boy born to the same mother has a greater chance of being gay, may be due to an increasing immunological response by a mother's body to each male foetus in her womb.

科学家称之为"兄弟出生顺序效应"的一种现象，是指同母所生的每个男孩比其上一个亲生哥哥是同性恋的概率要大，这可能源于母体对自身子宫里每个男性胎儿的免疫反应强烈程度逐渐上升。

It is important that the effect of the diagonal loading upon the GIP performance be analyzed particularly in theory, namely the rational diagonal loading can improve the detection probability and the output signal-to-noise ratio.

从理论上详细分析了对角加载对GIP性能的影响，即合理的对角加载可以提高检测概率和输出信噪比。

"The big trend with him in particular is that the first 15 games last season he refereed where we saw line movement of at least 1 1/2 points were a perfect 15-of-15 for the big-money people betting," said Matty O'Shea, general manager of content at pregame.com and a handicapper.

"唐纳西为什么会有这么大的嫌疑呢？因为在他上赛季执法的前15场比赛中，当我们看到盘口浮动至少1.5分的情况下，这15场比赛都是被人下了大注的。而这种事件随机发生的概率是1/33000"PREGAME。

The main content of preparation before scoring is selection of characteristics, which mainly uses Logistic regression, contingency table analysis and artificial neural network. Personal credit scoring and evaluation mainly uses general discriminant analysis, refined decision tree model, improved genetic algorithm, probability neural network and behavioral scoring model. The effect test of personal credit scoring includes fitting effect test and fitness test. The former involves right prediction rate, Kappa consistency test, ROC curve, and the latter includes likelihood ratio test, Hosmer-Lemeshow test, etc.

评分前的准备工作主要是特征变量的筛选，其中使用的主要方法为Logisitic回归、列联表分析和人工神经网络；本文使用的个人信用评分与评估方法为广义判别分析、精练决策树模型、改进遗传算法、概率神经网络和行为评分模型；个人信用评估的效果检验包括拟合效果检验和拟合优度检验两个方面，前者涉及的方法有预测的正确率、Kappa一致性检验、ROC曲线，后者主要包括似然比检验、Hosmer-Lemeshow检验等。
