查询词典 optimality principle

The studyshows that Chetaev's model for mechanicalsystems with non-holonomic con-straints can be reduced to three essential factors:(1)a kind of direct sum ofjet bundles according to the constraints,(2)D′Alembert's principle,(3)pos-tulate of ideal constraints.The first among the three factors only has geomet-ric significance and the second is a fundamental physics principle independentof any constraints.

研究表明，非完整约束力学系统的Chetaev模型归结为三个要素：(1)射丛按约束的直和分解；(2)D′Alembert原理；(3)理想约束条件，其中(1)仅具有几何意义，(2)为与约束无关的基本物理原理，而(3)是对约束力学系统的限制条件。

Or we could say: phenomenal truths are deducible in principle from physical truths, but the deducibility is akin to that of a complex truth of mathematics: it is accessible in principle, but is not accessible to us now, perhaps because the reasoning required is currently beyond us, or perhaps because we do not currently grasp all the required physical truths.

或，我们可以说：现象真，在原则上可从物理真推理得到，这推理能力就好比负责的数学真：原则上可达，但不是我们现在可达的，或许因为必须的推理是超出我们的，或许是因为我们目前没有把握所有必须的物理真。

To oppose Revelation with "a preliminary and comprehensive demurrer"("une fin de non-recevoir préliminaire et globale"-- Le Roy) in the name of the principle of immanence, is to misinterpret that principle, which, rightly understood, involves no such exigencies (see below,"The Method of Immanence").

反对与启示"的初步结果，并全面抗辩"（下称" une鳍德非recevoir préliminaire等全球"-乐罗伊）的名字，这一原则的内涵，是误解了这一原则，其中，正确地理解，不涉及这种严格要求（见下文，"这个方法的内在性"）。
