An approach to extension assessment of disaster vulnerability for small towns and its application;

Thinking on causes and tactics to the vulnerability of public environment;

Kill probability contour analysis method for assessing aircraft single hit vulnerability;

The design of derailleur strew thread plate, the structure and fixing mode of damageable parts of die are introduced, the replacement and repair of damageable parts can be accomplished without disassembly die on pressure machine, thus, the utilizing efficiency of die and equipment get improved, and the production costs get lowered.

The experimental results indicate that the low vulnerability of rocket motor with steel case is low;the fragmentation of the propellant depend on the mechanical performance;and the combustion inten- sity is effected by the thickness along impactiv.

The main properties and low vulnerability tests of 40NTO/60TNT and 25RDX/25NTO/50TNT formulations are researched.

This paper develops the method of delimiting vulnerable scope and assessing coastal vulnerability through the observation and sampling in the field and applying the means of remote sensing and GIS, which can be suitable for great river delta and coastal plains with great area, relative complex micro geomorphology and the protection of seawall.
