Total percent of carbon, nitrogen and phosphorus in Engraulis japonicus varied from 46.3% to 60.5%. And carbon content of Engraulis Japonicus was increasing and phosphorus was decreasing when growing from larvae to adult. However, there was not significant difference to nitrogen in different stages. Differences of nutrient contents in different life stages may be caused by changes in allocation of materials for growth within the body.

结果表明，碳、氮和磷三种元素占到鳀鱼体重的46.3-60.5％，其中碳元素含量与体长成正相关，磷元素与体长成负相关，氮元素与体长之间的联系并不非常明显，不同阶段的鳀鱼在元素组成上的差异直接反映了各阶段其需要不同物质。

Its mechanism is the use of anthraquinone in alkali conditions off proton surface forming 10 more stable carbon anion face, but because carbon anion and oxygen ion exist between testosterone and enolate type each other changes, cause reaction product complex, at least five, reaction selectivity, product yield, separation difficulties, and product purity is not high, therefore, using the type and quantity of alkali, phase transfer catalyst type, solvent, to optimize the selection process conditions so as to improve the yield target product.

其机理是利用蒽酮在碱存在的条件下脱去氢质子面形成10位较稳定的碳负离子面进行，但是因为碳负离子和氧负离子之间存在酮式和烯醇式的互变，导致反应复杂，产物至少有五种，反应选择性差，产物分离困难，产率低，且产品纯度不高，因此，利用对碱的种类和量的多少，相转移催化剂的种类，反应溶剂的选择，来优化反应工艺条件从而提高目标产物的产率。
