Experience shows that the introduced magnetic field can give an effective intervention to the transition of droplet, flowing of molten bath metal, crystalline and nucleation of molten bath and the process of crystalline growth. The magnetic field promotes the refining degree of primary crystallization structure , decreases the chemistry non-homogeneity, So it can strengthen hardness and wearing resistance of weld metal overlay and improve quality of surfacing deposit.

实践表明，利用外加磁场对焊接中熔滴的过渡、熔池金属的流动、熔池的结晶形核及结晶生长等过程有显著作用，使堆焊层的一次结晶组织细化，控制硬质相的分布，减小化学不均匀性，从而提高了堆焊层金属的硬度和耐磨性，全面改善堆焊层的性能。

Semi-thin sectioning and the method c.ommonly referred in histochemistry were used to study the development of vascular bundles in Aloe arborescens leaves with emphasis on the origins and tissue types of vascular bundle sheath cells and aloin-containing cells.

采用半薄切片和组织化学方法研究了木立芦荟叶内维管束的发育过程，并着重于维管束鞘细胞和芦荟素细胞的来源及组织类型。

It is generally accepted that in the Purex process, particularly in the first cycle, the crud occurrence is related to the capillary chemistry phenomena resulting from the deposits of Zr with TBP degradation products HDBP, H_2MBP, H_3PO_4 and the insoluble particle RuO_2 and Pd.

目前 ，普遍认为，在Purex流程萃取过程中，尤其是在一循环中，界面污物的产生与Zr和TBP降解产物HDBP、H2 MBP、H3 PO4 形成的沉淀以及料液中存在的不溶性RuO2 、Pd等微粒的表面化学现象有关。
