查询词典 performance evaluation

In recent years, high performance concrete (HPC, or high strength concrete-HSC) has been widely used in engineering practices such as bridges, runnels, tall buildings, offshore oil platforms and nuclear engineering applications due to its intrinsic properties of high strength, high durability etc. Hence, the prediction of HPC structures performance is of great practical importance, in particular for safety evaluation of HPC structures subjected to fire or other thermal hazard situations.

近年来，随着建筑结构性能要求的提高，高性能混凝土(HPC，或称高强度混凝土HSC)正逐渐蓬勃兴起并替代传统的混凝土用于桥梁、隧道、高层建筑、海洋石油平台和核工业设施等方面，因此对于高性能混凝土结构性能的预测显得十分重要，对火灾或其它高温危险环境下高性能混凝土结构安全性的评估尤其值得重视。

Finally, the comparison analysis of the performance evaluation results is given as well. Some conclusions, which is the performance comparison of the single-layered LEO satellite network and the double- layered LEO/MEO satellite network's with the variation of network load, are derived thereby.

The results showed that, on code evaluation performance, the effect of self-explanation was not significant between groups, but high prior knowledge learners outperformed low prior knowledge learners. On code generation performance, the guiding-question group outperformed the principle- prompt group and the control group. And the high prior knowledge group scored significantly higher than the low prior knowledge group. Finally, on the analysis of attitudes toward self-explanation activities, the guiding-question group showed more positive acceptance than the principle-prompt group.

研究结果发现：(1)在程式评估问题上，自我解释学习活动对学习成效没有显著影响，但高先备知识组则显著优於低先备知识组；(2)在程式设计问题上，问题引导组显著优於其余二组，高先备知识组亦显著优於低先备知识组；(3)在学习态度方面，问题引导组对自我解释学习活动的接纳程度和学习成效的看法上，皆显著高於原则提示组；两组对自我解释学习活动难度的看法则无显著差异。

This paper aims at the design, implementation and evaluation of an industrial brushless servomotor drive. The proportional-plus-integral speed control with gains tuned by an extension of the frequency-zone method and anti-windup PI speed control based on self-conditioning techniques are studied. The parameters of speed performance criteria, control loop bandwidth, per normal inertia, and noise sensitivity are employed to evaluate the performance of the drive.
