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。

He describes in an early novel the miraculous way in which a flat, abstract contrivance can take on vitality and light: Little by little, the pieces and squares began to come to life and exchange impressions. The crude might of the queen was transformed into refined power, restrained and directed by a system of sparkling levers; the pawns grew cleverer; the knights stepped forth with a Spanish caracole ...

他描述早期的小说用的是神奇方式的单元，抽象的创造的方式具有活力与轻盈：逐渐地从片断和广场开始，到生活和交流印象，一个有自然力量的女王可以转变完善权力制度，由闪耀的杠杆系统克制并且进行指挥，典当行业的增长使人更加聪明，骑士又加强了与西班牙马术中的回旋技术。

It is necessary to research statistical data quality and its management in order to satisfy the demand of statistical data from all levels, connect statistical data in our country with international data in the process of social economy development, and strengthen the international commensurability of the statistical data.

为了更好地满足社会经济发展过程中社会各界对统计数据的需求，为了使我国统计进一步与国际接轨，增强统计数据的国际可比性，有必要对我国统计数据质量及其管理进行系统深入的研究。

The system was also installed with the RS-232 USB connecter connected with PC, which could process the more complicated serial data and show their pictures via PC. Meanwhile, the starting and braking processes as well as the stability research during its normal performance could be better analyzed.

系统还设置有与咒计算机通讯的RS-232串行接口，可将连续测量数据通过PC机进行更复杂的数据处理和图形显示，能较好地分析研究机械转动设备的启动、制动过程及对械转动设备在正常运行过程中的平稳性研究。
