查询词典 experiment

We selected from 222 students at first grade in a primary school as subjects. A One to One intervention was given in the subjects by using self-made program computer programs. This study is composed of two experiments. The first experiment discusses the effect of self-explanation which guided by different direct instruction in problem solving on procedural learning, procedural transfer and conceptual understanding. The purpose of this experiment was to test whether self-explanation can promote transfer and which is the most the most effective combination of self-explanation and instruction. The second experiment, based on the results of the first experiment, compared the effect of self-explanation of different types in problem solving on procedural learning, procedural transfer and conceptual understanding. There are two methods: explain aloud, explain without voice. The purpose was to compare which effect is better?

In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

本文将遗传算法的四维同化系统运用到更复杂的MM5模式中，在理想实验中验证遗传算法同化系统的性能，并以2003年7月4日"南京暴雨"作为研究对象，进行了实际观测资料的同化，并将遗传算法同化系统和MM5伴随模式同化系统得到的结果跟未同化的结果进行了比较，结果如下：遗传算法同化系统不仅可以用在正压原始方程模式上，同样也可以用在MM5等复杂模式上，理想实验证明了遗传算法同化系统优于MM5伴随同化系统，在实际观测资料同化中，采用两种方法的同化系统都能有效地改善数值预报模式的初始场，能在一定程度上提高物理量场和降水量的预报效果。
