能算的

When data are balanceable, two methods should have no difference, but the standard error computed by two-level model is bigger than that by generalized estimating equation. When data were unbalanceable, generalized estimating equation shows somewhat advantage. Type 2 diabetes mellitus might exist genetic heterogeneity and there is no gene that is related with the occurrence of bipolar disorders.

当数据平衡时，两者结果一致，但多水平模型计算出的标准误大于广义估计方程算出的标准误；当数据不平衡时，两者结果不一致，广义估计方程更能检测出有统计学意义的基因位点。

The results of example indicate that the peak driving torque is minimized by modifying the stiffness and the unstrained positions of the flexure hinges.

根据算例分析结果可知，通过改变柔性铰链的刚度以及各柔性铰链未变形时的初始位置能减小机构的最大驱动力矩。

Secondly, the program of above method to deal with the data of free attenuating vibratin caused by smooth flow was used.

本文提出的方法能够用同样的辨识原理、同一个数据处理程序统一地对紊流和均匀流下的桥梁气动导数进行辨识；最后，利用数值仿真算例验证上述理论。

All people were frightened to scurry away at all directions when the governmental conscription order issued. Only Mr. Shu lingered freely on the street, without fear of the conscription. He also was the last man to be conscribed for the governmental service.

当政府徵兵召集令下达时，大家都吓的四处逃窜，唯独疏先生尚能大摇大摆地在街上游荡，完全不惧徵兵这码事；同样的，当政府要徵民劳役时，也始终算不到他的头上。

Took me endless trips to several retailers and a whopping three returns until I was somewhat satisfied — although I admit that I still sometimes regret not getting the cushier pillowtop, rather than the firmer mattress I ended up with.

我会往几家零售店来回跑上无数趟，还退了三次货，直到最后才算有点满意，虽然我承认，有时我还是遗憾没能买那套更舒适的软枕面床垫，而是买了最后的这个比较硬的弹簧床垫。

Nothing great or small escapes the ordaining hand of him who numbers the hairs of our head.

无论大事或小事都不能逃过上帝守望的眼睛，祂甚至连我们的头上的头发都数算过了。

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.

与现有方法相比，这种方法不需要获得系统元件模型和参数，而是直接球化广域测量系统(wide area measurement systems，WAMS)提供的发电机电角速度信号，再利用最大负熵准则进行独立分量分析得到特征矩阵，将高维数的多机受扰轨迹数据变换到低维空间，通过模式识别得到分群结果。8机36节点系统和西北750 kV电网规划系统算例表明，该方法能有效消除噪音和坏数据的影响，准确识别出同调机群。

Whether the normally affable Mr Clinton managed to stay poker-faced through the three hours and 15 minutes he and Mr Kim spent in each other's company (long enough, even with translation, for a chin-wag), his aides are not saying.

在其各自团队的陪同下，克林顿和金正日进行了长达3小时15分钟的会谈（即使算上翻译时间，对于一次&闲谈&来说，时间也够长了）。而平日里和蔼可亲的克林顿是否能成功板着一张扑克脸，我们则不得而知。

Get the students to understand the essence of addition and subtraction of decimals.

使学生理解小数加、减法的意义，掌握小数加减法的计算方法，并能较熟练地进行小数加、减法的笔算和口算。

The interaction between the extent and the period of ice force is expressed.

算例结果与几个有影响力的经验公式和理论公式的比较显示，新公式能更好地模拟结构的实际冰力。

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。
