The analysis of the continuous property of raw silk size Setting the decaying rateλand the quasi-cycle value T in the model of the silk size autocorrelation coefficient, building the time series of a single cocoon reeling silk size with autoregressive model, then by combining k such time series according to different phrase, obtained time series of the raw silk size, and finally count up the silk size deviation of the time series.

利用一理想化的正弦波模型生成一粒缫生丝纤度时间序列，通过调查该模型中波动幅度及波动周期的变化对自相关系数序列衰减率的影响，初步建立起一粒缫生丝纤度自相关系数列衰减率λ与纤度时间序列特征数之间的关系式。从而使我们可以生成具有要求连续性特征的生丝纤度时间序列，为进一步研究生丝纤度连续性特征提供了新的途径。

The results show that in the climatological sense, activity of synoptic-scale disturbance is much stronger in June and August, which is corresponding with the variation of jet stream.

这和急流的强度变化是相对应的，即，强的天气尺度波动活动量对应着强的急流，弱的天气尺度波动活动量对应着弱的急流。

The instantaneous angular speed based on the flexible body model underdiffierent faults simulated is calculated, which shows the rule of the instantaneousangular speed fluctuation ratio due to the underpower of a single cylinder. Therefore,the maximum power fluctuation ratio of the instantaneous angular speed is proposed to diagnose the fault of single cylinders underpower.

Independent toxicologists contacted by New Scientist said Séralini's analysis overplays the importance of minor variations that most experienced toxicologists would consider to be random background noise.

新科学家》（New Scienctist，此文发表刊物）联系的独立毒理学家也说，Séralini的分析过分夸大了统计数据里的微小波动，对大多数有经验的毒理学家而言，这类波动只能算背景噪声。

Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes.

你的脑波动也会稍稍减慢，但在最初的几分钟会以相当快的速度呈希腊字母第一个的形状波动。

The experimental results showed that the frictional factor periodically fluctuated with the time variable, and its amplitude was obviously affected by the change of Reynolds number and pipe diameters. The amplitude and average value of frictional factor both decreased with the increase of Re number, but the bigger the tube diameter was, the larger the amplitude of frictional factor was.

经实验研究发现，试验段内的摩擦阻力系数随时间变化有明显的周期性，雷诺数增加导致摩擦阻力系数的波动幅值降低、平均值减小，管径越粗使得摩擦阻力系数边的波动幅度越大。

PIC result shows that the alteration of spatial potential in the discharge space directly affected the distribution of the charged particles, it is just the fluctuation of potential distribution caused the density distribution of the charged particles, thus an alternating-electric field formed in the plasma space.

采用二维PIC-MCC方法对氮气对称结构射频放电进行了模拟研究，粒子模拟结果表明：放电空间内空间电势的变化直接影响了带电粒子的分布，正是电势分布的波动使得带电粒子的密度分布也出现了波动。等离子体空间内形成了交变电场。

Simulation result shows that X-ray spot size is almost certainly convergent when the number of beamlets increases gradually,and the convergent size is about 1.03 mm.

计算结果表明：子束流层数一定时，焦斑直径波动在0.03mm范围内；随子束流划分层数的不同，计算所得焦斑直径的最大不确定度为±0.05mm，而焦距几乎不变化，其波动在0.08cm范围内；随子束流划分层数的增加，焦斑直径计算结果是收敛的，最终收敛值约为1.03mm。

The way that concentrated slurry under requirement returns directly to the storage tank of feed slurry helps to keep the stability of feed concentration, which is the solution to the fluctuation of discharge concentration.

采取浓度未达标的浓缩完成液直接返回浓缩前储罐的方法，可以保持进料浓度稳定，系统控制的稳定性大大提高，解决了降膜蒸发系统由于进料浓度波动带来的启动波动大、控制困难等问题。

This article analyzes systematically the work process of fuel injection system in detail. It analyzes the fault fundamentals and its influence of three coupling parts in the high pressure oil road and the injection process, three coupling parts include plunger coupling parts, delivery valve coupling parts and needle valve coupling parts.
