在近年来的论文中,Munasinghe和Dis-sanayake(1979,1980a、b、c,1982)对斯里兰卡的地质演化提出了一个新的板块构造模式。所提模式的重要特征,是矿化带局限于两个“小板块”的边界,即现在的地质缝合线中(dissanayake和Munasinghe,1984)。将板块构造应用于前寒武纪还颇多疑问。

引言斯里兰卡的宝石沉积矿床闻名于世,矿床中所含的宝石矿物以刚玉、金绿宝石、尖晶石、石榴石、绿柱石、电气石、黄玉和锆石为主。虽然人们对这些宝石沉积矿床的矿物学非常熟悉,但是由于对它们的地球化学研究工作做得很少,因此对这些矿物的源岩和成因尚不清楚。Munasinghe和dissanayake曾对斯里兰卡的宝石成因做过研究,研究表明宝石矿物是经脱硅作用形成的,脱硅作用是紫苏花岗岩和其他基性岩(如富透辉石的岩墙和岩床)侵入到铅质变质沉积岩中的接触变质作用引起的。本文通过更详细的调查研究,论述了紫苏花岗岩在高级变质地体的宝石形成过程中所起的作用。

Introduction: Two spread methods of Covid-19, namely airborne and respiratory droplets, can be prevented by proper use of face masks. However, it has been reported an inadequate knowledge attitude and practice of proper use of face masks among school students. Therefore, the knowledge, attitude, and practice of school students should be improved. Different approaches are used to improve knowledge, attitude, and practice. However, e-posters are rare, and the effect of e-posters on improving the knowledge, attitude, and practice of school students on the proper use of face masks has not been studied. Objectives: The objective of this study was to determine the effect of an e-educational poster on knowledge, attitude, and practice of the proper use of face masks among school students. Method: This study was conducted as a pre-test and post-test design. The sample was 364 grade 11 students of the Gampaha educational division, sri Lanka. Data were collected using self-administered questionnaires distributed pre and post to the interventional e-education poster. Data analyses were conducted by using spss software. Results: Results show no significant demographic difference (p = 0.446) between the pre and post-test groups. A significant increase was observed between the pre and post-test mean scores of knowledge (p ≤ 0.05), attitude (p ≤ 0.05), and practice (p ≤ 0.05) on the proper use of face masks. In pre-group knowledge (p = 0.155), attitude (p = 0.258) and practice (p = 0.211) shows no significant difference due to gender. Also post group knowledge (p = 0.079), attitude (p = 0.835) and practice (p = 0.435) shows no significant difference due to gender. Conclusions: The results suggest that e-educational posters may be useful to improve the knowledge, attitude, and practice on the proper use of face masks among school students. The improvement of knowledge, attitude, and practice on the proper use of face masks by e-educational posters among school students occurs irres
