查询词典 optimality principle

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

Simulation of micro-milling process is conducted using finite element method. During modeling, the Johnson-Cook's coupled thermal-mechanical model was employed as workpiece material model, the Johnson-Cook s shear failure principle was adopted as work piece failure principle, and the coupled thermal-mechanical hexahedron strain hybrid modules and adaptive grid were used to remesh the workpiece's elements. The friction between the tool and workpiece obeys the amended coulomb's law that combines with the sliding friction and the adhesive friction.

The principle of legality in China's new criminal law established an important principle, which advocates "no crimen sine lege, there is no specific law does not punish" In other words, the law expressly provides for criminal acts, in accordance with Legal convicted and punished; law does not expressly provide for criminal acts, even if it has a certain degree of social harm, but because the law does not expressly provide, it is not punishment.

罪刑法定原则是我国新刑法确立的一项重要原则，它崇尚"法无明文规定不为罪，法无明文规定不处罚"，也就是说，对于法律明文规定为犯罪行为的，依照法律定罪处罚；对于法律没有明文规定为犯罪行为的，即使它有一定的社会危害性，但由于法律没有明文规定，所以不能处罚。

The principle of"nullum crimen sine lege,nulla poena sinelege"is the other principle that the International Criminal Courtshould follow.Because there is particularity when InternationalCriminal Court applies law,it does not exclude applying custominternational law while it applies the statutory crimes,punishmentand strictly prohibits applying non-retroactivity ratione.
