不偏

In theory, the proposed Blue-estimator is akin to the best invariant quadratic unbiased estimator.

理论上，本文所介绍的估计式(Blue-estimator)雷同於最佳不变二次无偏估计式。

So, we discuss the asymptotically best linear unbiased estimator for the logistic population based on the selected order statistics, give the pr.

为缓解这一困难，本文讨论利用样本分位数的Logistic总体的近似最佳线性无偏估计，给出估计量的大样本性质，以及样本分位数不超过10情形下，估计量有渐近最大相对估计效率时样本分位数的选取方案等。

Robust best invariant unbiased estimator, quadratical form, variance/covariance components

稳健最优不变二次无偏估计，二次型，方差和协方差分量

1 The reasons there are two main expressions for "population" and "sample"" is that one is "biased estimator and the other is not.

"母体"与"样本"之所以有两种表达公式，是因为一个是有偏估计，另一个则不是。

Instead of using the homomorphic filter which is used to get rid of multiple noise and is a biased estimator, this algorithm translates speckle into locally stationary additive white noise.

该算法不同于有偏的去除乘性噪声的同态滤波算法，而是将噪声转化为局部平稳的加性白噪声。

This paper proposes an algorithm named Small Sample Incremental Biased Learning Algorithm to solve three difficulties of relevance feedback in sketch retrieval, including small sample issue, asymmetry of training data and real-time requirement.

为了解决草图检索相关反馈中小样本训练、数据不对称及实时性要求这3个难点问题，提出了一种小样本增量有偏学习算法。

The sensitive amplifier has a circuit with simple structure, small occupied area, high read speed, low dynamic power, wide range of operation voltage and almost-zero static power and does not need a biasing circuit; the read circuit formed by the sensitive amplifier has the characteristics of anti-degradation of the properties of elements and stable performance.

该灵敏放大器电路结构简单，不需要偏置电路，占用面积小，读取速度快，动态功耗低，静态功耗几乎为0；工作电压范围大；由上述的灵敏放大器构成的读电路具有抗器件特性退化，性能稳定的特点。

New remove from office of bell of head of department of network of Dongguan city library introduces, collect books the net suffers " cold reception " reason besides collect books there are any conduct propagandas during the net is debugged beyond, the bibliophile age of Dongguan city slants big, unaccustomed arrange on the net collecting books also is a main reason.

东莞市图书馆网络部主任钟新革介绍，藏书网遭到"冷遇"的原因除了藏书网调试期间没有任何宣传以外，东莞市的藏书家年龄偏大，不习惯在网上整理藏书也是一个重要原因。

It is pointed outthat the intrinsic birefringence of the fiber is not low enough to be neglected.

本文研究了单模光纤中线偏振皮秒光的光致多脉冲现象，我们结合观察到的现象，指出光纤的残留本征双折射在实验中不能被忽略。

But my heart can not forgive that I get nothing but blankness from the world.

但不能平的，为什么偏要白白走这一遭啊？

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
