方法的

From the frequently used way that applying probe vectors for choosing promoter to the using of PCR, there were lots of ways for promoter cloning. Afterwards, a series of techniques based on PCR for promoter cloning such as I-PCR, P-PCR, SSP-PCR, YADE, TAIL-PCR were developed in succession. They offered more reliable and reasonable ways of cloning the promoter.

On the basis of getting the true and reliable monitoring datum, the methods of diagnosis algorithm based on state predicting are also discussed in this paper. A method based on BP artificial neural network is presented. A diagnosis model is also designed and emulated. The results of the emulations show that the algorithm is obviously better than that of the traditional three-ratio method, and the algorithm can accurately makes good judgments on the faults base on qualitative and quantitative analysis.

The first part of this paper goes to a thoroughreview of studies on methods for nonlinear least squares problems, which are then,from the perspective of arithmetic design, classified into five major types: methodsbased on quasi-Newton equation, hybrid methods, factorized quasi-Newton method,trust-region methods, and self-scaling method. The second part of this paper turns thefocus toward a type of new algorithms for nonlinear least squares problems based onnew quasi-Newton equation.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
