Firstly, a probability computing model is constructed to present system call sequences and the SCSFA algorithm is designed to predict the attempt of intrusion and to determine what need to protect, which is based on the analysis of system call sequence in virtual computing systems; Secondly, the sensitive data protected are divided into a number of film data, and for the goals of random errors tolerance, each tablet data are redundant backup based on Byzantine fault tolerance; Then, the redundant data are distributed to different virtual machines.

The number of errors in decimal place of mathematics students are more than that of normal students.

六、在小数的乘法计算，数学学习障碍学生较普通学生在计算小数位数上发生错误。

The paper analyses two kinds of new formulas on the equivalent friction coefficient of V-belt drive in the present mechanical design and finds out that one is reasonable but has certain error and the other is wrong.

对现行机械设计中关于V带传动当量摩擦系数的2种计算公式进行分析。认为其中一种公式是合理的，但存在一定的误差；而另一种公式却是错误的。通过推导V带欧拉公式，给出了计算V带传动当量摩擦系数的准确公式，并在公式中引入了一个新的参数——摩擦力方向角。在考虑皮带拉力变化既有径向滑动又有周向滑动的前提下，改进后的计算公式比现有公式更加完善

The model of weighted LRIV for topology error identification and the method of calculating the weighting factor are formed. It can make the weighted innovation value of the topology error branch show up and improve identifying ability for topology error in little load flow value branches.

形成加权新息识别拓扑错误的模型和权值计算方法，这种加权算法使得发生拓扑错误的支路相应的加权连支推算新息元素值加大，可以改善新息图法对于小功率支路上发生的拓扑错误的识别能力。

The theoretical analysis and experimental results show that the result of the first one has bug error with optimal results, and the second one is superior to the former, and the third one is best, which can get the optimal result based on least upper bound of error probability.

证实了"基于最小错误概率上界特征提取"是目前可以用迭代算法完成的最好的特征提取，而"基于马氏距离特征提取"在错误概率上界上升很小的代价下，简化了计算量，也是一种可行的方法。

In order to get the stress analytic solution, the stress equations are deduced with conformal mapping method and residue theorem, the defaults of equations in the reference are corrected. This method overthrows the obstacle in the engineering stress calculation for the flat receptacle with conformal mapping.

为了建立有实际意义的扁挤压筒应力解析解，本文结合单连体复变函数保角映射法和留数定理推导出受内压力作用的扁挤压筒的应力求解公式，更正了国外文献中相应公式的错误，开发了受内压扁挤压筒的应力计算程序，实现了应力计算的程序化。

In 1987, Kane et al.〓investigated the dynamics of a cantilever beam in a non-inertial reference frame.

建模时如果不考虑这种因素的影响，将会导致错误的结论。1987年，Kane〓对非惯性系下的旋转弹性梁的动力学特性进行研究，指出在转速较大的情况下，按零次近似建模理论进行仿真计算会得到梁的挠度趋于发散失稳这样一个错误的结论。

Inaccurate measurements lead to bad orbital parameters and hence bad ephemerides - this is why three measurements on an FMO are necessary for the MPC to accept an object onto the CP.

错误的测量会导致错误的轨道参数计算结果——这就是为什么在上报给国际小行星中心的时候一定要测量三个点才有可能被接受并出现在确认页面上。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
