In this paper, three robust estimators: robust best invariant quadratic unbiased estimator, robust minimum norm quadratic unbiased estimator and robust Helmert estimator have been designed. Finally, this paper states that these three classical estimators are particular cases of the RBIQUE.

导出了稳健最优不变二次无偏估计、稳健最小范数二次无偏估计、稳健Helmert估计，并说明了最优不变二次无偏估计、最小范数二次无偏估计以及Helmert估计等均是稳健最优不变二次无偏估计的特例。

Another research topic is evaluated lightning induced voltages on nearby overhead-lines. Lightning is a transient, high-current discharge whose path length is measured in kilometers. During flash, neighbor electromagnetic field change violently, that would induce voltages on close-by metal.

另一研究课题为，非直击雷害造成邻近区域内架空线上的感应电压的探讨，雷击闪络可视为长距离的放电暂态现象，过程中会使得雷击周遭的电、磁场剧烈变动，将会在邻近的金属物件上感应出电压造成二次的伤害。

These methods utilize successive approximation of initial problem by linear or quadratic problem.

A new method of obtaining secondary electron yield and secondary Cs〓 ionization probability by detecting target current and primary ion current under Cs〓 bombardment is put forward The dependence of Cs〓 ionization probability on primary ion energy, primary beam current and substrate compositions, as well as the dependence of secondary ion intensity on erosion time during transient period has been studied The mechanisms of secondary ion emission are explained

二、提出了通过测量靶流和一次束流求取Cs〓轰击下二次电子产额和二次Cs〓离化率的方法，实验研究了一次离子能量、束流强度及不同基体对二次Cs〓离化率的影响和瞬态过程中二次离子强度的变化规律，并对发射机理做了解释。

JK Rowling's first Harry Potter book wasrejected twelve times before it was finally published.

罗琳的第一本哈里·波特的书在最终出版之前遭遇到十二次的拒绝。

We note that the known APN polynomial functions are allquadratic except the APN functions recently found by Edel and Pott. In F22n, theAPN permutation has not yet been found. We construct low di?

我们注意到除了Edel和Pott最近发现的APN函数外，其它已知的APN多项式函数都是二次的，而且在F22n中还没有发现APN置换函数。

By default, the calculation is linear and unweighted, but quadratic and weighted variants are also provided.

缺省情况下，计算是线性的和非加权的，不过也提供二次的和加权的的变体。

We told them the refinishing work would have to include redoing the sizin, simply because the sizing place on the ring stood out and was discolored, with pits and holes in that area.

我们告诉他们的修补工作，要包括二次的压力机，因为浆纱于环站出来，变色，与老窖洞，在这一领域。

Raw sludge, no matter from primary or secondary settling, will not drain well on sand beds and will usually have an obnoxious odour.

生的泥浆，无论是来源于初次或者二次的沉淀，都不会很好的渗漏在沙床上而且会散发难闻的气味。
