The present experimental investigation attempts to understand the suppressing effect of metal mesh construction on deflagration waves of premixed ethyne air mixture in unconfined space.

Practice of Applying the Principle of Urban Open Space Ecological Planning——Research on the Urban Green Space System Planning of Jiangmen City;

An analysis of its landscape construction was made in terms of the road system, multilayer open space, and water landscape to provide a reference for design practice in tropical region.

With the penetration of the conception of "human-based" into human settlements, the functions of open space become more import, and the "open space first" the best planning procedure aiming better human settlements.

In view of the most fatal typical place in large emporium,the mathematical model and computer sim- ulating software-CSMOKE for smoke flowing process in the smoke-stop zone of open style space were built by using numerical simulation and computer simulation with two-layer zone model.
