Development and use of one-dimensional models of a golf ball

One-dimensional models of a golf ball are useful in modelling near-normal (90°) impact. The model described here has two masses connected by a non-linear spring in parallel with a non-linear damper. The behaviour of this system in collision with an infinite rigid mass is compared with the results of tests involving real golf balls. Values of the four unknown constants are found by fitting the model results, over a range of impact speeds from zero to 50 m· s -1 , to the coefficient of restitution and duration of contact found in the tests. The simplest model (Model 1) was a good fit for duration of contact over the whole range of impact speeds, but for the coefficient of restitution only at high speed (above 20 m· s -1 ). However, when used with a similar model of a flexible faced club, the simple model predicted the coefficient of restitution of the club-ball combination, determined by direct testing, quite well and as such is a useful screening tool. More complicated Models 2 and 3 fitted the rigid target coefficients of restitution better at low speed than Model 1. However, Models 2 and 3 have other disadvantages and are no better than Model 1 for high-speed impact with flexible faced clubs.     

学案式教学的知识生态学分析

学案式教学是以＂学案＂为导向来实施教学过程的一种教学模式。从知识生态学的角度来分析学案式教学是一个新的视角。知识生态学把知识分为数据资料、信息、知识和智能四种不同的知识形态,其核心是探讨知识如何向更有价值的形态转化及其所需的条件。学案式教学营造了从信息向知识、技能和态度转化的生态环境,并使其教学关注信息、知识如何经过集体和个体交融的学习活动,转化为学习者的能力、意愿、素质、心态以及集体高成效可持续的学习习惯。

What Teachers of Science Need to Know about Models: An overview

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: meanings of a model, purposes of modelling, multiplicity of scientific models, change in scientific models and uses of models in the science classroom. First, a model can be defined as a representation of a target and serves as a ‘bridge’ connecting a theory and a phenomenon. Second, a model plays the roles of describing, explaining and predicting natural phenomena and communicating scientific ideas to others. Third, multiple models can be developed in science because scientists may have different ideas about what a target looks like and how it works and because there are a variety of semiotic resources available for constructing models. Fourth, scientific models are tested both empirically and conceptually and change along with the process of developing scientific knowledge. Fifth, in the science classroom, not only teachers but also students can take advantage of models as they are engaged in diverse modelling activities. The overview presented in this article can be used to educate science teachers and encourage them to utilise scientific models appropriately in their classrooms.     

中国商事合会法制化研究

合会是我国传统的一种民间资金融通方式,其形式多样、种类繁多,其中商事合会是一种由特定企业组织、经营的合会形式.从域外商事合会的发展经验看,商事合会具有风险低、规模大、降低会员时间成本等特点;商事合会在促进民间资本融通、为农村建设和中小企业发展提供资金支持等方面具有重要的作用,因此在金融政策逐步开放、金融环境不断宽松的今天,我国应当通过立法,构建商事合会法律制度,引导和规范商事合会的发展,从而在防范合会风险的同时,充分发挥合会的积极作用,促进社会经济的发展.
