It is suggested that quite a lot of the Be, Co, Cu and Pb could be originated from the syngenetic stage during which the coal-forming plants grew. The strongly seawater-effected peat bog with the reductive and alkaline water could be in favor of the relative enrichment of the Be, Co and Cu, and the faintly seawater-effected bog with the slightly reductive and alkaline water could be in much favor of the enrichment of the Mn, Mo, Ni, P, Pb, Th, Tl and U.

认为凯里煤中相当一部分Be、Co、Cu和Pb起源于成煤植物生长期间的同生阶段；受海水影响强烈的还原偏碱性沼泽环境有利于Be、Co和Cu的相对富集，受海水影响微弱的弱还原性和弱碱性环境条件更有利于Mn、Mo、Ni、P、Pb、Th、Tl和U的富集。

PAHs (Polycyclic Aromatic Hydrocarbons) even of Power Tools in German; Ni Even of Wenzhou's Shoe in Italy, even a famous electronic manufacture had the pecuniary penalty of over hundred million US dollar due to the Cd, even of game boy's handle. In 2000 EU has constituted and announced ELV directive concerned with automotive industry only which strictly measures the use of some hazardous substances in vehicles. Then who will like to be the unfortunate in automotive industry?

电动工具在德国遭遇PAHs事件，温州鞋在意大利遭遇Ni事件，就连某国际著名的电器厂商也曾因游戏机手柄在荷兰遭遇Cd事件而导致过上亿美元的巨额罚款，而2000年欧盟已专门针对汽车业制定颁布了ELV指令，严格规定了汽车零部件及材料中的有害物质的限值，又有谁愿意成为汽车业的不幸儿呢？

A fragile penetrator material made of W-Ni-Al-Fe was studied. The material was made by CIP and sintering process.
