查询词典 mean error

The wide used method in weather, hydrography, etc., Kalman filter, is used to update the coefficients of the empirical model and expected to make better improvement. The test with the ionosound data of hourly values from 1986 to 1995 at Changchun illustrates that the root-mean-squre error of the forecasted values in one hour advance is 0.76 MHz in winter, 0.68 MHz in summer and 0.61 MHz in equinoxes, respectively.

尝试利用气象预报中常用的Kalman滤波方法对模型的系数进行实时修正，以提高预报精度，并对长春站1986-1995年近一个太阳周f0F2数据进行提前一小时预报试验。

The illiberality of parents,in allowance towards their children,is an harmful error;make them base;acquaints them sort with mean company;and makes them surfeit more when they come to plenty.

父母在子女幼时不可对他们吝啬，这是一种有害的错误，因为那会使他们感到自己卑贱，使他们学会投机取巧，甚至于下流人士同流合污。

The illiberality of parents, in allowance towards their children, is an harmful error; makes them base; acquaints them with shifts; makes them sort with mean company; and makes them surfeit more when they come to plenty

在子女小时不应对他们过于苛吝。否则会使他们变得卑贱，甚至投机取巧，以至堕入下流，即使后来有了财富时也不会正当利用。到中国译典经典版本中查找关于surfeit的最新解释和例句。。。。

The illiberality of parents, in allowance towards their children, is an harmful error; makes them base; acquaints them with shifts; makes them sort with mean company; and makes them surfeit more, when they come to plenty: and therefore, the proof is best, when men keep their authority towards their children, but not their purse.

父母给子女零花钱和补助费表现吝啬，是有害的错误。--这可以使子女变得卑贱、小气；使子女学会玩弄心计；使子女跟卑贱之流为伍；使子女掌管大量钱财时更加挥霍无度；所以，人们对子女，最好保持权威，而不是看住钱包。

The illiberality of parents, in allowance towards their children, is an harmful error; makes them base; acquaints them with shifts; makes them sort with mean company; and makes them surfeit more when they come to plenty.

The conventional adaptive beamforming techniques like MMSE and NLMS beamformers can not provide a satisfied performance in some situations such as antenna array overloading and a small angle difference between a desired signal and an interferer.

在天线阵列超载，以及强干扰与期望用户信号夹角过近的情况下，传统的线性阵列信号处理算法，如MMSE(minimum mean-square error)、NLMS等表现并不理想。

The main content includes that the accuracy of interpolation operators is creased since defect equations introduce less error: Gauss-Seidel solution can save effectively the computational time, in particular, the CPU-time for the setup phase; Jacobi-relaxation interpolation contributes to efficient and robust algebraic multigrid methods by a simple and purely algebraic mean.

最主要的内容是基于亏量方程引入的误差较小，从而进一步提高插值算子的精度；采用Gauss-Seidel解法有利于节省计算时间，特别是预备阶段的CPU时间；插值的松驰以一种简单的纯代数的方式获得高效且稳健的代数多重网格算法。

Measures of variability include range, interquartile range, standard deviation, and standard error of the mean.

变异程度的测量包括范围、四分位差、标准偏差和平均数标准误差。

What's more, we also study some key techniques and realization difficulties of image authentication in-depth, including referent block to help tamper localizing, sign bit adjustment for binary encoding, mean quantization improvement, diagonally extension to help tamper localizing, and discard isolated error point to tolerate incidental distortion. These techniques can be used for good reference to the development of image authentication technique.

此外，我们还对数字图像鉴别的一些关键技术和实现难点进行了深入研究，主要包括有：参考点辅助定位技术、二值编码中的符号处理技术、均值量化方法的改进技术、对角扩展和去除孤立点技术等，这些技术的研究都对数字图像鉴别技术的发展具有很好的借鉴意义。
