The cause of macromastia is not well understood and may be related to the mistakes in gene expression during puberty or pregnancy. There are a lot of researches focusing on the molecular mechanism of breast cancer and lactation, but seldom on macromastia. The size of an organ is determined by the size of the cells and the number of the cells, which depends on cell division and cell death.

巨乳症的成因可能是由於青春期或怀孕期乳房发育基因的表现异常而造成，但目前的研究对此并没有很详细的研究，与巨乳症相关的研究大多集中於病患的心理生理评估及手术方法的比较，乳房发育的相关研究目前都集中於乳癌与泌乳退乳的机制。

With Yangtze delta tidal flat as an example, through the analysis on the magnetic characteristics of tidal flat sediment and the study on the space distribution of heavy metal elements, this thesis discussed the impact to Shanghai sea bank brought by heavy intensity development, and the interrelation between sediment power effect and heavy metal pollution space distribution. Utilizing the advantage of artificial intelligence neural network, in conjunction with environmental chemical analysis, from the angle of view of sediment magnetic characteristics, it analyzed the connection mechanism between magnetic mines and heavy metal element within tidal sediments, and built a quantitative magnetical diagnosis model, in attempt to calculating the tidal heavy metal pollution status from the magnetic measurement data of sediments and assess it's impact to the environment.
