查询词典 variation

In modern physics research, the calculus of variations has a broad application of law. As a solid mechanics, structural mechanics and computational mechanics of the theoretical foundation, it has important value in theory and practice on the mechanics; Variation method ruled out the perturbation of the restrictions can be widely used in many state-level and the state function in the calculation in the optical; Calculus of variations can be calculated with the parameters, we can guarantee the reliability of the results, can effectively reduce the workload of calculation, It can be said that the applications of calculus of variations are very broad.

在现代的物理学研究中，变分法有着广泛的应用：在力学上，变分法作为固体力学、结构力学及计算力学的理论基础，在理论上和实践上都有重要的价值；在光学上，变分法排除了微扰法的限制，可以广泛应用于诸多定态能级和态函数的计算中；在量子力学的应用中，具有可算出系统的参数，既可以保证计算结果的可靠性，又能有效地减少计算的工作量等的优点，可以说变分法的应用领域十分广阔。

The richness center of the Theaceae plant species under study is located in the mountainous area of north Guaugdong (22.5°N, and 112~115°E). These plants species exhibited significant longitudinal difference (P=0.0012), and latitudinal variation (P=0.0049). Canonical Correspondence Analysis showed the distribution of plant species could be explained by caloric factors and moisture factors, and MAMI (mean annual minimum temperature) was the key factor determining the distribution pattern of Theaceae plant species richness in the study area.
