[en] Based on the characteristic of far-region NEMP, this paper discusses methods and theories of far-region nuclear explosion detection by NEMP from two aspects, identifying far-region NEMP and the relation between far-region NEMP and parameters of nuclear explosion. (authors)

[en] The paper describes the overall program of training simulator. The results show that it can solve the practical problems and meet the demands by tests. (authors)

[en] It is simulated on dynamic pressure of shock wave of the low air nuclear explosion by large-scale commercial software of FEM-MSC.DYTRAN in this paper, and makes use of static loading to turn the difficult problem-hydro-solid coupling to the approximate static state. And we get the distortion of a special structure by dynamic pressure, which is compared with the result only by overpressure. This method can be a kind of references on the simulation of dynamic pressure of shock wave. (authors)

[en] The problem is that a Goniometry Detector is unable to be used to train, which lacks of simulation training environment and real training conditions. Its basic working principle is analyzed, and the overall program which is suitable to the training simulator is raised. We also describe the design of light source. We developed a set of experimental device and did some experiments on the basis of it. The experimental results show that technical approach of the program is feasible and the basic performance can meet training needs. The set of experimental device can solve practical training problems and play an important military benefit by improvements. (authors)
