Gene mutations in human gene can cause various diseases . The human autosomal dominant brachydactyly type B ( BDB ) and autosomal dominant polycystic kidney disease ( PKD ) are due to gene mutation on chromosome .

人类基因组上基因的突变可以引起各种各样疾病的发生，人的常染色体显性的B型短指和常染色体显性的多囊肾综合症就是由于染色体上的基因突变引起的。

With the increase of the ratio of BDB to AIBN and the concentration of BDB , the reaction rate decreases , the molecular weight for polymer with similar monomer conversion during the emulsion polymerization becomes smaller , and the molecular weight distribution will also be narrower .

本体共聚配方中BDB/AIBN的比值越大、BDB用量越大，乳液聚合速率越小，相近转化率时产物的分子量越小，分布也越窄。
