中文摘要：

抛物面槽式太阳能集热器热性能测试主要可以分为稳态和动态测试2种方法，依据二者所采用的物理模型，比较它们的应用范围，并且分析各自的优缺点．基于北京延庆实验平台测得的天气和集热器运行数据，运用最小-乘法进行模型的多元回归，得到稳态测试模型和动态测试模型的判定系数分另0为0．58和0．96．研究表明：对于稳态测试方法，虽然物理参数少，但测试条件要求极高，只能在特定的实验装置上进行，不适合于实际运行方式下的槽式集热器；而动态测试方法充分考虑集热器的光学响应和热容特性，因此很大程度上降低了测试条件，使现场规模化槽式集热器热性能测试成为可能，是未来标准测试方法的发展趋势。

英文摘要：

Test for thermal performance of paraboloidal trough solar collectors can be chiefly divided into two kinds as steady-state test and the dynamic one. Based on the physical models employed, their applica- tion ranges were compared and their advantages and disadvantages were analyzed. By means of multiple re- gression of the data on the weather and operation of test platform at Yanqing district, Beijing with least squares method, the determination coefficients for the steady-state and dynamic models were 0. 58 and 0. 96, respectively. The investigation result showed that, although the mathematical model of the steady- state method would include less physical parameters, the requirements of test conditions would be ex- tremely strict, meaning that this method could only be used on a particular experimental setup and it would be not applicable to paraboloidal trough solar collectors operated in actual practice. As for the dy- namic method, however, the optical response and thermal capacitance of collectors were carefully consid- ered, and consequently the test requirements were dramatically lowered, making the on-site test for deter- mining thermal performance of utility-scale paraboloidal tough solar collectors possible and it would be the tendency of the future standard test method.
