There were obvious biases in codon usage of PCGs , U and A were prefer in codons .
密码子的使用出现明显的偏好性,倾向于使用由U和A组成的密码子。

So a novel approaches that BP networks with the characteristic of simulating non-linear function at will is applied to ground fault line detection in PCGS is put forward , the results of simulation show the method is nicely and credibility , and can be used in practice .
本文介绍利用BP网络来描述这种映射关系,并确定接地故障线路(或母线),以实现小电流接地系统的接地选线。仿真结果表明,该方法快速、准确,具有一定实用价值。
