So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。

In his early works, there were themes and symbols he had put into use continuously, such as the weird figure with an official hat, then big beard Marx who also symbolized academic authority in the duration of his study and pretty woman dressed erotically, and so on.

另外如破碎的酒瓶；豹皮和太阳镜；燃烧的火堆，风景中的暴力案件；倾倒的马和人体等等，这些情节和道具对应了作品中的诸多元素：权力、欲望、暴力、个人意志……这些元素呈现出不同的表达谱系，产生了多样的视觉刺激，在一个被颠覆的系统中呈现着各自的面貌。

Exogenic elements enriched in low-grade section,such as Li and Ti;while endogenic elements,represented by Sr and Ba in low concentrations.
