一、principle、rule一般指科学原理和法则,例如:
Newton’ laws of motion are the basic principle of mechanics. (牛顿运动定律是力学的基本原理。)
Maxwell’ equations are the rule electromagnetic fields and electromagnetic waves follow.(麦克斯韦方程是电磁场和电磁波遵循的法则。)
注意:在学术论文写作中,我们一般很少用到principle和rule,我们都是探讨一个“具体的”技术问题,涉及不到基本原理和法则。
二、criterion和norm是论文写作中会用到的,例如:
To devise a cryptographic scheme, we follow the criterion/norm that it should be both secure and efficient. (我们设计密码学方案时遵循的准则是它既安全又高效。)
注意:当用于判断的准则时,用criterion而不是norm,例如:
According to the criterion, the campaign they launched is unlikely to be deemed a success. (根据准则,他们发起的运动不可能被认为是成功的。)
Turning Test is accepted as a criterion for judging whether a machine has intelligence. (图灵测试已经被作为判断一个机器是否有智能的准则/标准。)
Every two years, the JPEG committee received lots of candidate techniques and investigated using a set of criteria. Those that passed the test are included in the JPEG standard. (每两年JPEG委员会会收到大量候选技术并根据一套准则对它们进行研究,通过测试的那些技术成为了JPEG标准的一部分。)
