摘要：船体结构极限强度是船体结构安全检验中的重要参考指标,因此船体结构极限强度模型试验技术在船舶工程行业中发挥着十分重要的作用,基于此,本文针对船体结构极限强度模型试验技术的应用进行详细的研究分析。在极限强度模型试验相关原理的基础上,从对甲板加筋板和箱型梁对不同模式下的船体结构极限强度模型试验技模型设计进行分析,最终采用实际的船体结构极限强度模型试验对极限强度模型进行验证。

摘要：In order to analyze the learners＇ cognitive process under the teacher＇s focus-on-form feedback on second language writing, this study carried out an simulation experiment to investigate learners＇ correction rates and confidence levels according to three major variables： feedback modes, error types and treatment orders. The results show that： （1） treatments of ＂Code＂ and ＂Underline＂ both had their advantages and disadvantages under different situations; （2） different types of errors are sensitive to different feedback modes; （3） orders of treatment may influence learners＇ perception of instructor＇s intention; and （4） learners＇ confidence level may record the cognitive level of the target language and correlate with the correct rate. Finally, it is suggested to pay more attention to the interactive mechanism of feedback effect and to apply more diversified treatments under various situations in practice.
