教育用简单大气电子仪器的构造细节
Constructional details for A simple atmospheric electrical instrument for educational use
摘要:
大气中的电为环境科学的教育推广提供了一个理想的主题。为了支持这一目标,一个简单的仪器来测量真实的大气电参数已经开发和其性能评估。该项目是对欧洲大气层耦合研究合作组织开展的教育活动的补充。这种新仪器造价低廉,操作简单,很容易在学校和大学本科一级使用。它适合各种不同教育水平的学生,因为结果可以用不同的复杂程度进行分析。学生可以测量晴天的电场和电流密度,从而了解大气的电学性质。这项工作是由1906年的百年纪念论文,其中C.T.R.威尔逊描述了一种测量电场和传导电流密度的新仪器。在1979年之前,英国一直定期使用基于相同原理的仪器进行测量。所提出的仪器基于与C.T.R.相同的物理原理。威尔逊1906年的乐器这里提供了仪器的结构细节。
英文摘要:
Electricity in the atmosphere provides an ideal topic for educational outreach in environmental science. To support this objective, a simple instrument to measure real atmospheric electrical parameters has been developed and its performance evaluated. This project compliments educational activities undertaken by the Coupling of Atmospheric Layers (CAL) European research collaboration. The new instrument is inexpensive to construct and simple to operate, readily allowing it to be used in schools as well as at the undergraduate University level. It is suited to students at a variety of different educational levels, as the results can be analysed with different levels of sophistication. Students can make measurements of the fair weather electric field and current density, thereby gaining an understanding of the electrical nature of the atmosphere. This work was stimulated by the centenary of the 1906 paper in which C.T.R. Wilson described a new apparatus to measure the electric field and conduction current density. Measurements using instruments based on the same principles continued regularly in the UK until 1979. The instrument proposed is based on the same physical principles as C.T.R. Wilson's 1906 instrument. The constructional details of the instrument are provided here.
