法律行为汉字术语的日本翻译与中国传播史

“法律行为”一词乃日本明治时期法学家所创造。根据立法会议记录,日本德式新民法草案最初采用的术语是“法律上的行为”,后来才改采“法律行为”。“行为”一译,是沿用了日本法式旧民法中“acte”的译法。然而,起草委员们未注意到德国学说上“Rechtsgeschaft”与“Rechtshandlung”之分,故“Rechtsgeschaft”“Rechtshandlung”“acte juridique”曾被当时日本文献视作同义。因立法后术语难再改动,起草委员们只能以学说之名,将“法律行为”分为广狭二义,广义者指“Rechtshandlung”,狭义者指“Rechtsgeschaft”,而“acte juridique”可作广狭二用,至于“法律上的行为”,则专指“Rechtshandlung”。因“行为”同被用于“Geschaft”“handlung”甚至“Akt”等,使汉字术语相当混乱。这一混乱随着清末留日学生翻译的日本著作与讲义传入我国。译本的不理想,使我国错失改译的良机。本文发现了两部从未被引用的文献:1917年,余棨昌对“法律行为”译语提出了批评,这一发现可将学界认知前推90年;1977年,刘世民首次提出改译方案,主张将“法律行为”改译为“法律事务”。虽然21世纪又出现了各家改译方案,但将“Rechtsgeschaft”与“Rechtshandlung”分别译为“法律行为”与“法律上的行为”仍是主流。

The effects of a harmonically exciting monopole source on an infinitely long cylindrical cavity embedded entirely within a fluid-saturated poroelastic formation of infinite extent are examined theoretically. It is assumed that the source is located outside the cavity at a specified distance from the borehole axis. The magnitudes of the hoop and radial stresses beside the pore pressures exerted on the interface and inside the porous medium surrounding the borehole are calculated and discussed. Biot's poroelastic modeling along with three types of boundary conditions for the cylindrical interface including the ideal fluid, empty borehole, and rigid inclusion with a hard boundary is employed for the analysis. Utilizing a proper translational addition theorem for expressing the incident spherical wave in terms of cylindrical wave expansions, the proposed boundary conditions at the interface are satisfied. Stresses are formulated by means of wave potential functions in a three-dimensional(3D) manner. The effects of the frequency and the radial distance between the source and borehole on the induced stresses are examined for the first cylindrical modes over frequency spectra. Two permeability conditions for the interface and three types of soils for the porous formation are considered throughout the analysis. To give an overall outline of the study, a numerical example is presented. The results clearly indicate that the distance is a key parameter and has considerable effects on the induced stress values. In addition, the interface permeability condition and soil characteristics play an important role in determining the dynamic response of the borehole. Finally,the obtained results are compared with the relevant analyses existing in the literature for some limit cases, and good agreement is achieved.

Currently, there are a limited number of dynamic models available for braided composite plates with large overall motions, despite the incorporation of three-dimensional(3D) braided composites into rotating blade components. In this paper, a dynamic model of 3D 4-directional braided composite thin plates considering braiding directions is established. Based on Kirchhoff's plate assumptions, the displacement variables of the plate are expressed. By incorporating the braiding directions into the constitutive equation of the braided composites, the dynamic model of the plate considering braiding directions is obtained. The effects of the speeds, braiding directions, and braided angles on the responses of the plate with fixed-axis rotation and translational motion, respectively, are investigated. This paper presents a dynamic theory for calculating the deformation of 3D braided composite structures undergoing both translational and rotational motions. It also provides a simulation method for investigating the dynamic behavior of non-isotropic material plates in various applications.
