The calculating results are compared with the test data in available literatures and FEM results. The research results show that the plastic hinge model is precise and correct, which can satisfy with the actual engineering demands. The collapse pressure of perforated liner casing decreases with phrase angle, initial ovalization and diameter-thickness ratio increasing, and increases with the yield stress. The phrase angle and initial ovalization have greatly influence on the collapse pressure. The collapse pressure of perforated liner casing is slightly changed with the diameter and density of perforation when the diameter and density are smaller than 12mm and 120 shots per meter, respectively.

计算结果表明：筛管抗挤强度的塑性铰模型具有很高的计算精度和准确度，可以满足工程实际需要；筛管抗挤强度随着射孔相位角、径厚比和初始椭圆度的增加而降低，随着屈服强度的增加而增加，相位角和椭圆度对筛管抗挤强度影响比较显著；在射孔直径小于12 mm、射孔密度小于120 孔/ m 时，筛管抗挤强度随射孔直径和射孔密度增加变化不明显。

While trying to get a grasp of the septile aspect, I went back to John Addey (1920 1982), a key voice in bringing Pythagorean understanding of numbers into modern astrology. He wrote Harmonics in Astrology in 1976; it is now back in print after many years. He writes that the number seven (and the 7th harmonic)"is a difficult number to pin down" and "somewhat elusive to interpret."

为了试图给7分相位一个浅显的解释，我找到了历史上的一位占星家，名叫 John Addey ，将毕达哥拉斯对数字的理解带进了现代占星学，他1976年出版了一本《占星中的数字和谐》，书中有关数字7和7分相位，他写道&它是一个很难确定，很难下结论的数字&并且&不太容易解释和捉摸&。

Chapter 4 discusses the maximum likelihood sequence estimation for CPM on the multipath channels, advances the adaptive MLSE technique for CPM on unknown multipath channels, and establishes the mathematical model and the realization way of adaptive equalization on time－variant and time－unvariant multipath channels.

Therefore, local wave decomposition technology was introduced into the logging date extrapolation method constrained by time-phase model to gain the seismic instantaneous phase. The relationship of logging and seismic data was established through the wellside strata correlation. High resolution attributes inversion profiles were generated through the extrapolation of logging constrained by equiphase surface established based on seismic data.

In addition to setting the clock frequency, the master must also configure the clock polarity and phase with respect to the data. Freescale's SPI Block Guide [1] names these two options as CPOL and CPHA respectively, and most vendors have adopted that convention.

除了设置时钟频率，主设备同样需要设置数据传输相关的时钟极性以及相位。freescale'sSPI的手册命名这分别以cpol以及cpha来标志时钟的极性以及相位，大部分的芯片厂商采用了这种协定。
