Since the enciphered OTP, being transmitted, is known, one might, however, consider the following arrangement, which involves sending only one message, to be equivalent: take a fixed random sequence of letters (perhaps derived from the digits of pi; since we're using Playfair, we need a 25-letter alphabet anyways), then encipher (or, to be strictly equivalent, decipher) it using the current key by simple columnar transposition, apply the result by Vigenere to the plaintext, then encipher the result with Playfair.

由于加密检察官办公室，传送，是众所周知的，其中一个可能是，但是，考虑下列措施，其中包括派遣只有一个讯息，以相等于：以一个固定的随机序列的信（或许来自两位数丕；以来，我们再利用playfair ，我们需要一个有25个字母组成的字母anyways ），然后加密（或者，必须严格当量，破译），它利用当前的重点由简单的柱状换位，申请结果vigenere向明文，然后加密结果与playfair 。

A PCR product was amplified using RT-PCR method from total RNA from the abdomens of R strain using the degerated primer. The PCR product was purificated and cloned. The plasmid is pBluescript Ⅱ KS. Recombined plasmid DNA was identified by endoenzyme. The results indicated there were different P450 genes in the PCR product.

运用这对简并引物首次从德国小蠊抗拟除虫菊酯的品系R中扩增出的特异性的DNA片段，经纯化、连接和转化，重组至pBS质粒，筛选阳性克隆，提取重组质粒的DNA，并经初步的酶切鉴定，发现存在着不同的CYP4基因。
