催陈白酒回生现象对策

综述了现行人工催陈白酒技术的种类和弊端，认为回生现象是催陈技术不可避免的方法缺陷，单一的催陈方法无法实现理想的陈酿效果。以内部催陈法配合外部低能量处理的组合催陈技术是科学的方法，能够最大限度地克服回生现象的不良影响。应注意因采用新科技手段使白酒出现的异常成分对人体健康的影响；主张生产优质白酒应以自然陈酿为主要方法，适当的科学催陈处理只应该是辅助手段。     

半导体物理中电子的运动与有效质量的关系

当研究半导体中的电子在外力作用下的运动时,引入了有效质量这个概念,其概括了半导体内部势场的作用,使得在研究半导体中电子在外力作用下的运动规律时,可以不涉及到半导体内部势场的作用,有效质量将量子力学结果与经典力学牛顿第二定律联系起来了,本文主要研究半导体中电子在外力作用下的运动状态,并讨论有效质量与E-k图、平均速度和加速度的关系。     

建筑结构地震响应混沌特性及影响因素分析

采用混沌时间序列分析方法分别对以经典混沌信号和地震动为激励的结构响应进行混沌特性分析,从关联维数、Kolmogorov熵及最大Lyapunov指数等定量指标的角度,考察结构自振周期、地震动的类型和幅值等因素对结构地震响应的非线性特性的影响。研究结果表明:在经典混沌信号和地震动作用下,经过结构的放大和滤波作用,结构加速度响应仍然保留了混沌特性,且通过混沌参数的变化程度能够判断结构是否进入弹塑性状态。结构自振周期为结构加速度响应的混沌特性的主要影响因素;幅值对经典混沌信号作用结构下加速度响应的混沌特性影响较为显著;而地震动的类型、幅值等因素对地震动作用下响应的混沌特性影响更为显著。

Jump Distance Increases While Carrying Handheld Weights: Impulse, History, and Jump Performance in a Simple Lab Exercise

This laboratory exercise is designed to provide an understanding of the mechanical concept of impulse as it applies to human movement and athletic performance. Students compare jumps performed with and without handheld weights. Contrary to initial expectation, jump distance is increased with moderate additional weights. This was familiar to Ancient Greek athletes where halteres were a part of the original Olympic jumping sports. The effectiveness of this laboratory was assessed with a prelab questionnaire evaluating understanding of the concepts relevant to jumping mechanics and a postlab questionnaire assessing understanding of the same principles in the context of a different but mechanically analogous circumstance, that of throwing. Results indicate that understanding improved significantly as a result of participation in the laboratory exercise.     

How students conceptualize grade‐based acceleration in inclusive settings

Despite extensive research supporting educational acceleration for students with high academic ability, some psychologists, counselors, and educators express concerns about accelerative interventions. Such concerns often hinge on uncertainty about social acceptance, even in inclusive education settings. Research on acceleration has consistently shown benefits for students with high ability; however, there is a lack of research about grade‐based acceleration in inclusive schools. This study engaged two groups of students in group concept mapping processes to examine how they conceptualized beliefs about grade‐based acceleration in inclusive schools. First, 26 students in inclusive classes generated beliefs about grade‐based acceleration. Then they, and a group of 14 students with high ability, structured the data by sorting and rating a synthesized list of the generated beliefs. We analyzed the sorted data using multidimensional scaling and hierarchical cluster analysis. The resultant cluster maps revealed some differences and some similarities in the ways that the two groups of students conceptualized beliefs about educational acceleration. Practical implications are discussed.
