说明：  这篇规范的初衷是为基础库代码的重构制定一套统一的规范。一方面可消除基础库中的一些常见的不安全隐患，一方面使基础库的对外展现趋向一致，提高代码的可读性，保证代码的质量.
(The original intention of this specification is based on the reconstruction of the library code to develop a uniform set of norms. Based on the one hand, the library can eliminate some of the common hidden dangers on the one hand to show the basic consistency of external libraries to improve the readability of the code, to ensure code quality.)
