The results of its 1D test demonstrate that the MARED code is suitable for simulating implosions on different devices and with a wide range of load parameters. Combination of the wire-array Z-pinch experiment simulation and analysis shows that under the same load conditions, the X-ray radiation power produced by the tungsten wire-array implosion is much greater than the power generated by the aluminum wire array. With the same load current, the greater load mass gains the lower X-ray power.

And shape by using X-ray to penetrate the log . The absorb of X-ray between log internal defect and log internal xylem is different .so the X-ray photograph is different .If we can get the several side X-ray photograph of log .and input the photograph into computer to digital image process . Then we can get the data and the location of log internal defect .

由于原木木质部分与内部缺陷部分对X射线的吸收能力不同，在X射线底片上形成的影像也不一样，如果对检测原木从不同的方向进行照射，再把得到的射线底片输入至计算机内部进行处理，就可以得到原木内部的大致空间结构参数，对原木的加工有重要的辅助作用。
