The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

In the computer simulation aspect, following work has been down:At first, the Wolfgang Schreiner's model is employed and extended to a new computer arteriole optimal growing model. Many new algorithms are described, such as signal tracing, resistance calculating, resistance balancing and flow balancing. With these algorithms and methods, the arteriole networks can be grown successfully on microcomputer.Secondly, a growing-network ordering method, which is called auto-centripetal ordering method of the growing networks, can be employed to order the growing networks to calculate the average parameters of the networks in level series.
