利用显微镜、ＳＥＭ、ＸＲＤ和化学分析等手段研究磁场作用下形成的磷酸钙盐的形态和结构以及相应溶液的变化．结果表明磁场作用下形成磷酸钙盐结构上有多相生成，形态上易得到比较小的颗粒．溶液的电导率、表面张力经磁场作用后有所下降，反应４８小时后的溶液中磷的含量经磁场作用比未经磁场作用的高２～３倍．磁场对弱酸的影响较大，实验结果为磁场的作用影响了磷酸氢根离子中质子的迁移，改变了溶液中的磷酸根离子的电离平衡以及各种磷酸根离子与钙离子的化学平衡，抑制了磷酸钙盐的正常生长，使之不能形成致密的较大的晶体颗粒．
The morphology and structure of the calcium phosphate salt formed by the magnetic field and the corresponding solution changes were studied by means of microscope, SEM, XRD and chemical analysis. The results show that the formation of calcium phosphate under the action of magnetic field has multi-phase structure, morphology is relatively easy to get smaller particles. The conductivity and surface tension of the solution decreased after the action of the magnetic field. The content of phosphorus in the solution after 48 hours of reaction was 2 to 3 times higher than that of the solution without the magnetic field. The effect of the magnetic field on the weak acid is large. The experimental result shows that the effect of the magnetic field affects the proton migration in the hydrogenphosphate ion, alters the ionization balance of the phosphate ion in the solution and the chemical balance of various phosphate ions and calcium ions, and inhibits The normal growth of calcium phosphate salt, so that it can not form a dense larger crystal particles.
