In fact, the coagulating mechanism was surface chelating and surface sedimentation. It was said that adsorption was before hydrolysis, then the hydrolysis and sedimentation reaction of the polynuclear hydroxy complexes took place on the adsorption surface, at the same time they counteracted the electric charge of the colloids and suspended substances then adsorbed and bridged the flocculates.

其混凝机理实际上是表面络合及表面沉淀过程，即絮凝剂投入水体后，其最佳混凝形态及其聚集体在一定时间内具有稳定性而保持其原有形态，并很快吸附在颗粒物表面，吸附过程先于水解过程，因带电荷及分子量较高而同时发挥电中和及吸附架桥作用。

The numerical results of stationary and transient Green'sfunction for high-velocity surface-head wave on some selected crystals are comparedThrough the above analyse,it is indicate that the first arrival wave mode is thelongitudinal-wave head-wave,and its propagate velocity is equal to the groupvelocity of the longitudinal bulk wave alone the surface.Furthermore,this modedoes not have the Δv/v effect,i.e.,its velocity is the same no matter the surface isfree or metalized.

通过对表面激发的瞬态和稳态Green理论分析和数值计算，表明在压电晶体表面上实际上看到的最高速的最先到达的波动模式是纵波头波，它具有沿表面纵波的群速度，而且对压电晶体，它不具有Δv/v效应，即在自由表面和金属化表面其传播速度是一样的，而压电晶体表面波及伪表面波均存在Δv/v效应。

Microanalyses have shown that during brazing Ti in AgCuTi alloy transferred preferentially to the surface of the cBN grit, and bonding behavior on cBN surface by AgCuTi alloy filler metal is realized through TiN and TiB2 which are produced by interaction between Ti atoms of AgCuTi alloy and N or B atoms of cBN surface. Thus, the chemical metallurgic bonding has been formed in the interface between AgCuTi alloy and c-BN grit.

微观分析表明：钎焊过程中AgCuTi合金钎料中的Ti向cBN磨粒表面富集，并与cBN磨粒表面N和B元素发生反应，形成TiN和TiB2，实现了AgCuTi活性钎料与立方氮化硼磨粒的化学冶金结合。
