The effect of colinearity is to make the regression coefficients unreliable . 共线性的影响是使回归系数不可靠。

In consideration of the colinearity between the activities of avermectin pks domains and structure of the polyketide product , the dh2 domain of avermectin pks , which corresponds to c - 22 , 23 dehydration , appears to have partial dehydratase activity and this results in a mixture of c - 22 , 23 double bonds ( " 1 " components ) and c23 hydroxy compounds ( " 2 " components ) 目前国内外尚未见有关仅产阿维菌素b1菌株的报道。根据阿维菌素pks基因结构与其聚酮合成反应步骤之间的线性关系，推测b2组分的产生可能是由于阿维菌素pks模块2中脱水酶( dh )的不完全活性所造成。
