实验科学

Science Alive is jointly organised by the British Council, the Education Bureau and the Hong Kong Science Museum, and sponsored by the Croucher Foundation. Every year, Science Alive invites leading UK academics and communicators in the field of science to present lectures and workshops to students and teachers in Hong Kong. The programme, which receives a huge level of support from schools throughout Hong Kong, delivers lively and provocative events which promote a wider understanding of science.

活动简介「活的科学」由英国文化协会、教育局及香港科学馆合办，裘槎基金会赞助的科学教育活动系列，每年均邀请来自英国的杰出学者和科普工作者为本地学生与教师举行讲座及工作坊，透过令人印象深刻的实验示范及互动学习模式，以轻松有趣的方法介绍科学知识，深受学界支持。

Initial experiments, reported recently in the Journal of Animal Science, show that the process does not affect the hatchability of tested eggs, and appears to be virtually foolproof, if rather long-winded (the results are available only after two hours).

最初的实验最近在《动物科学》杂志上发表，实验表明上述筛选过程并没有影响实验样蛋的孵化率。并且即使是在相当繁琐的情况下（得到实验结果一般需要两个小时），实验结果也似乎是可靠的。

Four groups of experiments with different level--indoor simulation experiments, lysimeter experiments, pot culture experiments and field plot experiments-- were carried out to systematically study the environmental effects following the application of fermentation sludge to farmland in Tianjin area, which include soil salinity and potential contamination on ground water, and to primarily investigate the fertility of NovoGro in agricultural soil.

本论文通过四组不同层次的实验—室内模拟实验、渗滤实验、盆栽实验和小区实验，首次对酿造污泥农业利用可能产生的环境影响：1NovoGro对土壤的盐分效应；2NovoGro对地下水的潜在污染，进行了比较系统的研究，同时对NovoGro的肥效特性也做了初步的探讨。成功地解决了制约酿造残渣在天津地区农业利用的关键问题，为酿造污泥的综合利用提供了科学的依据。

Objectivist regarded science as a description of nature.

本文首先概括介绍诺尔-塞蒂纳的建构论的哲学任务，然后分析建构性科学观的具体表现即科学实验之建构和科学论文之建构，最后评价诺尔-塞蒂纳的建构性科学观。

The teaching term took sixteen periods. The curriculum contained two topics,"acid and base", and "Taiwan's climate". Experimental treatments were teaching method. The research tools utilized in the study were " Science Concept Comprehension Test, Science-related Attitudes Scale, Problem Solving Ability Test and Questionnaire on the Attitude toward Science Teaching". A pretest administered before the experimental treatment and a posttest was held after the treatment. The data of SCCT, SRAS, and PSAT collected from pretest and posttest were analyzed by two-way ANOVA. Responses from the QAST were analyzed by ANOVA.

本研究的实验处理为以问题为中心的合作学习教学，研究工具包括「科学概念理解问卷」、「科学相关态度量表」、「问题解决测验」、「对自然科的教学态度问卷」、「教学检核量表」及「问题中心教学自我评估量表」，分析「科学概念理解问卷」、「科学相关态度量表」和「问题解决测验」资料时，以前测经验和教学法为自变项，后测为依变项，进行二因子变异数分析；「对自然科的教学态度问卷」采用单因子变异数分析；「教学检核量表」及「问题中心教学自我评估量表」则用来检核研究者的教学是否符合研究者的研究设计；在质性资料的部分，则分析学生的上课纪录、教师教学反省纪录及对自然科教学的态度问卷的理由。

From the angle of designing economics experiments, we conclude and presente five aspects that researchers must pay attention to, that is, experimental procedure standardization, experimental motivation saliency, experimental instruction unbiasedness, calibration definition, and design parallelism.

从经济学实验设计的角度，总结提出了科学的经济学实验所必须注意的五个方面，即实验程序标准化、实验激励突显化、实验语言无偏化、比较基准明确化、与现实的一致性。

In the course of experimental teaching, a virtual research subject about effects of He-Ne laser innovation ability, integrated analysis ability and autocephaly scientific reseach ability, was used for understanding and holding a normal rule and metthod to offer experience for scientific research in the future.

在实验教学中，我们结合聚γ-谷氨酸生产菌He-Ne激光辐射效应这一具体的科研课题，让学生以一个接近科技前沿的科研实验为导线，培养学生的创新能力、综合分析能力和独立开展科学研究的能力，由此了解和掌握科研的一般规律和方法，为其以后从事科学研究提供实践经验。

The purpose of the examinatorial and designing analytical chemistry experiments is to develop students' abilities of utilizing the learned knowledge on analytical chemistry to solve the problems on experiment and improve their comprehensive abilities and skills in analytical chemistry.

分析化学实验是我校应用化学专业、食品分析专业、生物技术专业、动物医学专业和动物科学专业等学生必修的专业主干课，它的开设为培养和训练学生具有较强的科学实验能力和逻辑思维能力、分析问题和解决问题的能力，及具有良好的科研素质奠定了基础。
