摘要： 国际条约以“转化”及“纳入”的方式在一国发生法律效力。在“转化”方式下，国际民商事实体性条约是以国内法的形式出现，以国际私法的指引而得到适用。在“纳入”方式下，国际民商事实体性条约的适用有“非国际私法模式”和“国际私法模式”两种。中国《民法通则》第142条第2款和《联合国国际货物销售合同公约》第1条第1款(b)项属于“法际私法”，解决国内不同法律之间的适用关系，它只有在“国际私法模式”下才得以适用。

Abstract: International treaties normally become legally effective in a domestic legal system through the approaches of “transformation” and “incorporation”.Under the approach of “transformation”, the international treaties concerning substantive law are transformed into parts of domestic law, which can be applied under the guidance of private international law.Under the approach of “incorporation”, the application of the international treaties concerning substantive law could be divided into two models: “the mode of excluding private international law” and “the mode under the guidance of private international law”.Both article142 (2) of the General Principles of the Civil Law of PRC and article 1.1(b) of the CISG are “private inter-legal law”, rules dealing with the application of different laws in a country, and these two can only be applied under the guidance of private international law.
