Research showed that: during the transient liquid phase diffusion bonding process, there exists a critical value about the choice of the bonding pressure.

研究表明：瞬时液相扩散连接中，压力的施加降低了液相的最大宽度，同时降低了降熔元素的总量，可以减少完成等温凝固所需要的时间。

When the reaction products form as high melting point CA2, CA6 and MA spinel in a continuous solid phase it will clog the liquid channel and resist the further diffusion of fused slag in the brick.

并且当熔渣与耐火材料的反应产物为高熔点的CA2、CA6和MA尖晶石相且连续交错分布时，能堵塞液相扩散通道，抑制熔渣向耐火材料内部的进一步渗透。

Thus it is of great significance to both evaluating the mud ability to stop gas in diffusion phase and estimating the gas diffusion amount.

对于准确评价泥岩阻止扩散相天然气能力和估算天然气扩散都具有重要意义。
