In this and other areas Protestantism's scriptural principle has itself been articulated in different ways, both to sanction the retention of traditions not repugnant to Scripture (a typically Lutheran and Anglican approach) and to debar from the church's life anything not explicitly warranted in Scripture (a tendency of Reformed Protestantism implemented most consistently by Puritanism and some derivative traditions).

在这一领域和其他领域新教的圣经原则，本身就是阐明以不同的方式，既要制裁保留传统的不令人厌恶的，以圣经（一个典型的信义和英国圣公会的办法），并取消比赛从教堂的生活没有明确什麼值得圣经（一种倾向新教的改革实施最一贯的清教和一些衍生物的传统）。

Polymerization of a phenylacetylene monomer bearing a dendron moiety was carried out by using a rhodium complex Rh[Cl2]2 as catalyst. The structure of the resultant was characterized with infrared, nuclear magnetic resonance, and UV-visible absorption spectroscopic techniques; the experimental data confirmed the generation of the expected polyphenylacetylene derivative (P1) with dendron pendants.
