“罪刑法定”和“罪刑相適應”這兩個原則均為中國刑法規定的一項基本原則。涉及到這種專業術語時，首先需要了解其意思，然后再搜索查證是否有官方譯文，不能閉門造車。

“罪刑法定”原則的基本含義是“法無明文規定不為罪”和“法無明文規定不處罰”。即犯罪行為的界定、種類、構成條件和刑罰處罰的種類、幅度，均事先由法律加以規定，對于刑法條文沒有明文規定為犯罪的行為，不得定罪處罰。

在此從China Daily上查到了對于罪刑法定原則的幾種譯法，分別為：the principle of legally prescribed punishment for each specified crime、no penalty without a law、assessing penalty by law，具體見下文。其中第一種譯法稍顯繁瑣，第三種比較直白，而第二種則出自一句拉丁語，Nulla poena sine lege，意思是法無明文規定不處罰，因此，翻譯時可以采用第二種為主。

“The Opinions on Pushing Forward the Reform of the Criminal Litigation System Centering on Trials” and its implementing rules have been released to accelerate the reform of the criminal litigation system centering on trials, to strictly carry out the principle of assessing penalty by law, evidence-based adjudication and excluding illegally-obtained evidence, to guarantee legalization and justification of trial procedures, and to ensure that trial in court plays a decisive role in investigating facts, confirming evidence, protecting litigants’ rights, and impartially adjudicating cases.

罪刑相適應原則是指“刑罰個別化原則”的對稱。又稱“罪刑均衡原則”。也稱“罪刑等價原則”。刑自罪生，罪重刑重，罪輕刑輕，罪刑均衡。既犯罪是原因，刑罰是結果，刑罰由犯罪所引起，犯罪社會危害性重的，刑罰亦重，犯罪社會危害性輕的，刑罰亦輕，刑罰的輕重取決于犯罪社會危害性的大小，犯罪社會危害性的大小決定刑罰的輕重。

關于這一原則的譯法主要有以下幾種：the principle of suitable punishment to each crime; the principle of suiting punishment to crime，差別不太大，翻譯時兩者皆可。
