For settling problems about launch equations of separation in different launch environments, the separation trajectory equations were established based on mass conversation, energy conversation, motion functions, state functions and many complex resistance constructed trajectory equations, and compiled simulation software about grand-water and air launch which can realized multi-parameter input, multitarget...
A Virtual Training System of radioactive aerosol 's concentration measurement is constructed based on Virtual Reality. Firstly, 3-d geometric models about radioactive aerosol's outer environment, detector, intelligent scaler and air sampling pump etc. are constructed, the general radioactive law based on face radioactive source is presented. These models are driving in general program platform using...
FFD algorithm is a main method on geometry sculpture, but this approach is only used in globe region and in geometry deformation. We present a new FFD method based on physics which is created on mass-springs model with local deformation character, so this geometry method can be with physics attribute, which extend application fields of FFD method greatly.
