查询词典 achievement test

The results indicated that most students were dependent on the problem's surface structure for their sortings. Futhermore, an interaction effect was found between the student's grade and their achievement. As the grade level increase, instesad of using surface structure, high achievement students tended to sort problems according to their semantic structure. On the contrary, low achievement students became relied more and more on the surface structure of the problems while sorting.

另外，学童之年级及其数学成就对他们采用何种策略解题有交互影响；随年级的提升，高数学成就组学童倾向放弃弃表面特徵，而改较高层次的语意结构作为分类的基础；反之，五年级低成就组学童则变得更依赖问题的表面特徵作为分类的依据。

The holistic design of the system and resolved the designs of software and hardware based on VXI bus are put forward according to the demand of test system. The hardware and software is designed, including the formation and design of hardware system, visual instrument software architecture, program design for instrument driver, high speed real-time data collection. In the dynamic test program, the idea of"software is instrument"was applied to meet the diverse test demands. Last, it is proposed that the VXI test system be developed to more totalization and networked. The basic theory of system identification was introduced briefly at first. The principle of spectrum analysis system identification based on Wiener-Hopf equation was expatiated. and the questions in applying Peusdo Random signal as spectrum analysis methods stimulate signal was studied, The generation principle of the peusdo random signal is researched, the characteristic of peusdo random are analyzed from time domain and frequency domain, the inverse repeat peusdo random signal is brought forward to make up the shortage of ordinary peusdo random signal. And a new chaos genetic algorithmis presented to solve the unprecise problem of the traditional method. In the servo valve dynamic characteristic test system, the spectrum analysis methods was applied successfully, the servo valve dynamic characteristic could be acquired rapidly and exactly, the test results were analyzed and the ameliorate methods were brought forward at last.
