偏态分布

However, we found, for nonstationary panels with deterministic trends, the S_N test statistics would be biased and its asymptotic distribution would not be standard normal.

但我们的研究表明，在非平稳综列数据含有确定性趋势时，SN检验是有偏的，不再服从标准正态的渐近分布，而需要进行修正。

One of such distribution functions can be used to describe satisfactorily the three-dimensional quasi-stationary grain size distribution obtained from experimental measurement results for pure iron by serial sectioning, and those obtained from computer simulations by vertex method, surface evolver method, phase-field method, Monte Carlo method with Potts model.

采用纯Fe实验数据以及顶点法、基元演化法、相场模型和Monte Carlo法进行了验证，结果表明，函数族中峰值左偏的函数适合三维准稳态晶粒尺寸分布的定量表述。

An improved method is used to describe non-linear characteristics of oil film.

本文提出了改进的模型，用模型中各参数随偏心率的非线性分布来反映油膜力的非线性特性，使该模型能够进一步用于转子系统进入涡动状态后的瞬态运动描述，并给出了利用差分解获得模型中各参数近似估计的方法。

Then we systematically study state transition probability of two-unit series system and paralleled system and stable availability of system, and drew the following conclusions:Firstly, we present the partial differential equation which satisfies state transition probability of the two-unit series system, and proves that state transition probability satisfy the equation, and are their minimal nonnegative solutions.

然后对两个不同型部件、一个修理设备组成的串联系统和并联系统的状态转移概率，以及系统的稳态可用度进行系统研究，得到了如下一些结果。第一，对两个不同型部件、一个修理设备组成的串联系统，其寿命和修理时间的分布函数的各种情况，给出了状态转移概率所满足的偏微分方程组，证明了状态转移概率满足的方程，并且是这些方程的最小非负解。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
