Three-dimension scene simulation technology of virtual environment maybe widely applied in many fields such as virtual battlefield, tourist industry and city planning. The technique has been applied to the research of “Virtual Battlefield” which provides a new research topic in the today’s world. And simulation training system of cruise missile is very important in the whole R&D (Research and Development) process because of the complexity and uncertainty of the real battlefield environment. In this paper, in allusion to the problem of simulation training system of cruise missile GUI, some key technologies about how to realize the system are introduced, including 3D modeling, object picking up, multi-channel comparison, object hierarchical display and so on. Accordingly, the six freedom motion simulation system is presented, which was established by Visual C++. Secondly, establishing cruise missile entity model in Multigen Creator and putting it into the vision simulation system that is build up by Vega Prime. At lastly, combining two simulation systems into an integrity one. The integrity simulation system performed well in test.

Water Supply Pipeline

The underground water supply pipeline information system used currently is short of describing the pipe in three dimensions. Aiming at this point, the 3D underground pipe information system was achieved with the help of three-dimension graphics tool (VTK) in this paper. With the system, users can browse the 3D underground pipes and search interrelated datum, which raises the efficiency and standard of city digitizing management.

Inelastic Mean Free Path

In analytical electron microscopy, it is often important to know the local thickness of a sample. The conventional method used for measuring specimen thickness by EELS is:where t is the specimen thickness, λi is the total inelastic mean free path, IT is the total intensity in an EEL spectrum, and I0 is the zero loss peak intensity. This is rigorouslycorrect only if the electrons are collected over all scattering angles and all energy losses. However, in most experiments only a fraction of the scattered electrons are collected due to a limited collection semi-angle. To overcome this problem we present a method based on three-dimension Poisson statistics, which takes into account both the inelastic and elastic mixed angular correction.The three-dimension Poisson formula is given by:where I is the unscattered electron intensity; t is the sample thickness; λi and λe are the inelastic and elastic scattering mean free paths; Si (θ) and Se(θ) are normalized single inelastic and elastic angular scattering distributions respectively ; F(E) is the single scattering normalized energy loss distribution; D(E,θ) is the plural scattering distribution,
