各国民事立法为了贯彻意思自治原则,几乎无一例外地规定意思表示应该自愿、真实,并通过对意思表示进行"质"的评价来影响民事法律行为的效力。但是,各国立法并没有因为民事主体的意志瑕疵而绝对否定其行为的效力,而是在私人的意志宣布与... 详细信息

各国民事立法为了贯彻意思自治原则,几乎无一例外地规定意思表示应该自愿、真实,并通过对意思表示进行"质"的评价来影响民事法律行为的效力。但是,各国立法并没有因为民事主体的意志瑕疵而绝对否定其行为的效力,而是在私人的意志宣布与外显的意志信赖之间寻求一种平衡,以保护对意志的合理信赖。我国民事立法和民法理论一方面将意思表示自愿、真实作为民事法律行为的有效条件来加以规定和认识,另一方面却没有完全否定非自愿真实行为的效力,这既造成立法上的逻辑混乱,又忽视了对意志信赖的保护。因此,在私人意志宣布与合理信赖平衡的基础上追求意思表示的自愿、真实成为我国民事立法的应然选择。

通过室内试验研究土体孔隙液中重金属离子影响土体物理力学性状的机理,采用不同浓度的重金属Cu2+、Zn2+、Pb2+掺入高岭土、伊利石类黏土和钠基膨润土,研究土体界限含液率、不排水抗剪强度随重金属离子浓度的变化规律。试验结果表明:以高岭石、伊利石为主要黏土矿物的低活性土的液限、塑性指数随离子浓度的增加而增大,钠基膨润土则表现出相反的变化规律;低活性黏土的不排水抗剪强度随离子浓度增加而增大,高活性黏土强度则随之减小;基于已有的无污染土体物理力学性状定量联系,分析重金属污染土的不排水抗剪强度与液性指数的定量关系,发现重金属离子引起的不排水抗剪强度的变化可以归结于重金属离子引起的液塑限变化,表明重金属Cu2+、Zn2+、Pb2+污染过程基本没有产生化学反应,其物理力学定量关系与已有的无污染土经验关系式一致。

The local structure and thermophysical behavior of Mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloys. The robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RMSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy was analyzed. The effect of Mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy, which is particularly pronounced in the 80at% Mg system and disappears at elevated temperatures. The density, self-diffusion coefficient, and shear viscosity for the Mg-La liquid alloy were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.
