By the method, the phase shift of signal was realized with programma. Together with variable gain larger and ilter processing, it made a positive feedback loop to compensate the variation energy loss of micro cantilever.

利用FPGA的可编程数字信号处理功能实现信号的移相，并与可变增益放大、滤波处理模块一起构成正反馈环路。

The main method used to detect the periodic variation signal caused by the back-up rool's eccentricity is MFFT (Modified Fast Fourier Transform).

主要控制思想是预先模型识别加在线参数自学习，主要数字信号处理手段是MFFT。

Test result makes clear, different intensity grade abandons the stuff of second birth wide market that gets after concrete mix up, of the compressive strength of concrete of second birth of different origin of compressive strength; that will reduce second birth concrete significantly all be worth concrete of singler source second birth to reduce, and variance and coefficient of variation increase; to use normal school model to be opposite of compressive strength of concrete of different origin second birth distributing undertook examining, use Monte-Carlo imitate method farther test and verify should distributing the rule.

试验结果表明，不同强度等级废混凝土混和后得到的再生粗集料，将显著降低再生混凝土的抗压强度；不同来源再生混凝土抗压强度的均值较单一来源再生混凝土减小，而方差和变异系数增大；采用正态分布模型对不同来源再生混凝土抗压强度的分布进行了检验，利用Monte-Carlo模拟方法进一步验证了该分布规律。

Finally, based on the geological structure underlain by gravel sand, it calculates the stability factors of Xixipu landslide with the remained slip force method under several water conditions. The results show that the variation of water level in Three Gorge Reservoir has significant influence on the stability of Xixipu landslide. Therefore, great attention should be taken to Xixipu landslide in the prevention design.

根据下伏卵石砂土层的地质结构，对西溪铺滑坡的稳定性进行了评价，评价结果表明库水位的变化对西溪铺滑坡的稳定性有巨大的影响，在滑坡的防治设计中必须引起高度的重视。

Seven polyimides were synthesized and their films were uniaxially stretched to observe the variation in their in-plane birefringence. The creep method of DMA was used instead in stretching the PI films. The preload force and isothermal temperature were the two controlled factors that were chosen on the basis of the lowest stretchable force and lowest temperature for each PI structure. The elongation ratio of a PI film was then decided by the stretching time.

在此是以DMA 的另一种试片拉伸方式-Creep模式，来取代之前的Stress Relaxation模式对PI薄膜试片进行拉伸实验，Creep模式是以最低的拉伸力量及最低的拉伸温度的前提下，选择Pre-load Force与Isothermal Temperature这二项为拉伸控制因素，在此状态下的PI薄膜拉伸比是取决於其拉伸的时间，此种拉伸模式将可得到较高的拉伸比，而高的拉伸比是获取较高薄膜双折射率的必要条件。
