In this thesis, we apply the equations of motion of steady Mach reflections and the oblique shock theory to derive polynomial expressions of the forms of f(r,Mo,P1) of downstream sonic and strong/weak separating conditions of reflected shocks of perfect-gas steady Mach reflections. We then obtain polynomial expressions of the forms of f(r,M0) for the limiting Mach angle condition of the above two expressions.

本论文首先应用稳态马赫反射流场运动方程式及斜震波关系式，推导出理想气体稳态马赫反射流场之反射震波下游之音速条件与反射震波之强弱分界条件之曲线解公式，并应用该曲线解公式来推导反射震波俱音速性质於Mach angle条件及反射震波俱强弱分界性质於Mach angle条件之公式。

In order to enlarge capacity building size and to enrich exploitation seismic interpretation methods, gamma log curve without container rock velocity information and resistivity logging curve were converted to realize the purpose of seismic inversion as pseudo sound wave curve, and to make the seismic inversion data volume have information of shale content and oiliness and help to predict the sandstone thickness and oiliness of reservoir bed.

为扩大油田产能建设规模、丰富开发地震解释方法，本文把不具备储层速度信息的伽玛曲线、电阻率曲线通过一定的转换，实现作为伪声波曲线进行地震反演的目的，使地震反演数据体加入泥质含量及含油性两种信息，有助于进行储层砂岩厚度预测及储层含油性预测。

Through the correlation analysis of log curve, AC is reconstructed with the chosen SP and GR.Then seismic inversion is carried out.The result can well distinguish the sand from the mudstone.It also reflects the sand horizontal distribution and the vertical thickness, which can effectively guide the production.

Their original lyrical themes dwelled mostly on Satanism and anti-Christian subject matter, but from second album "Blessed are the Sick" onward, the lyrics slowly moved toward the Ancient Sumerian Gods, though much of this is a nod to the Simon Necronomicon, which was influenced by Sumerian mythology as well as author H.P. Lovecraft[1], as well as a fascination with the Roman Empire, though anti-religious elements continue to permeate the lyrics.

他们原来的抒情主题谈到大多撒旦教和反基督教题材，但是从第二张专辑"有福的病态"以后，歌词慢慢走向古代苏美尔神，尽管还有很多的，这是一个点头的西蒙Necronomicon ，这是受苏美尔神话以及作者惠普洛夫克拉夫特，以及着迷罗马帝国，虽然反宗教分子继续渗透到歌词。

Just pay attention to that the gains for plus and minus signals are the same, and the area of the signal around zero. I checked the LM35, the accuracy is good, but does it need 2 diodes in series to measure the temperature lower than -20 degree C? You could consider TC1047A that I used before, it doesn't need any other component, and it can go directly to A/D.

我用4051是想将AD620的＋/-输出信号不通过绝对值电路，而是接一个反相电路，反相前后的信号通过4051和极性判断电路有选择的将信号的绝对值电压再送入AD，用这个方法也能处理温度传感器LM35的输出信号，我想这是个比较安全的方法了吧！
