The process of fabric combustion is that the material absorbs heat and decomposes to form combustible materials (usually gases), and then ignites and burns. The heat released during combustion promotes thermal decomposition and ignition. As shown in FIG. 2, the following three conditions must be met for fabric combustion:The fundamental way to put an end to waste is to make the quantity of production consistent with the quantity of sales. If the production is arranged from the front process to the back process according to the traditional processing sequence, the higher the production efficiency of the process, if its rhythm is not suitable for the back process, the more waste of manufacturing surplus will be generated. Therefore, JIT production reverses the traditional way of transferring parts from front to back, and puts forward the order requirements from the back process to the front process according to the order method. The front process only provides the necessary products in the necessary quantity when necessary. Users can supply as much as they need, thus realizing "zero inventory" and not occupying working capital. Commodities that users do not need will not be produced, which can avoid overstock, obsolescence and deterioration of commodities, and can also avoid the costs of loading and unloading, handling and inventory.谁知你演了这么一出戏，竟然能翻身。如果不看的话，你绝对会后悔的。杨长帆颇为失望，客套几句后告知狼兵驻扎地点，求到一些补给后就此别过。《佛本是道》是神话，不是童话。他举着双手，边说边退了一步。
