Result:1. There were significant reductions in the total visual field sensitivity, the mean deviation(MD) and the pattern standard deviation (PSD) in 2mm diameter group, when compared with 4mm group (except supratempard quadrant).2.
结 果一、2mm后囊膜孔组的视野指标MD(平均偏差)、PSD(样本标准差)及各象限的总光敏感度较4mm后囊膜孔组(除颞上外)和后囊膜透明组相比有显著性差异(P<0.05)。

Two kinds of resource management algorithms, the minimum mean deviation criterion and the minimax deviation criterion, are proposed, respectively.
分别提出了基于协方差偏差均值最小准则和最大协方差偏差最小准则两类资源管理算法。
There were significant correlations of decreased RNFLT and macular volume with measures of visual acuity, low contrast visual acuity and visual field mean deviation in the MS patients.
减少的视网膜神经纤维层和黄斑面积与视觉准确度有明显的相关性,低的视觉对比准确度和视野均差在多发性硬化患者中为低。
The modified model yields much better prediction compared to the prediction with the original model for asymmetric systems, the mean deviation of bubble pressure decreased by more than 25 percent.
对非对称体系的预测结果比原模型有很大的提高,压力预测平均偏差平均下降了约25%。
And then I could also do a Gaussian one here, with the mean of and the standard deviation of volatility divided by 2.
然后我在这里再写一个高斯分布的函数,它的浮动值的平均值和,标准偏差值都除了2。
It could be normal, everything, that would be a Gaussian, where if you recall there was a mean, and a standard deviation, and most values were going to be close to the mean.
可能是正态分布,也就是高斯分布,只要有平均值和标准偏差值,你就可以进行调用,大部分的值都是集中在平均值附近的。
What we want to do now is compute the mean and variance of the portfolio-- or the mean and standard deviation, since standard deviation is the square root of the variance-- for different combinations of the portfolios.
我们现在要做的是,计算这个投资组合的均值和方差-,或者均值和标准差,因为标准差的平方就等于方差-,这对任何投资组合都是一样的。
