环境监测管理与技术 1993年第2期5卷 63-64页

作者： E.K.harrison b.S.THOMAS 孙瑞林罗军湖北省环境保护研究所监测中心站 430072

介绍了光谱法测定焦化厂大气颗粒物提取液中煤焦油沥青挥发物.通过已知浓度提取液校正后,能使测定具有与目前使用的重量法相当的准确度,即±2.6μg/mL提取液.本法优点是能在远少于重量法所用时间内测出结果.

引言地貌学家用了20多年的时间先后建立了一些相当复杂的坡面侵蚀模型。例如,杨(Young.1972)总结了四类坡面演化模型:(1)根据直线后退建立的模型;(2)根据蠕动和流动机制建立的模型;(3)涉及形态相互作用的模型;(4)根据过程量测建立的模型。在前两个模型中,明显存在一种可以得出两个基本方程的逼近收敛性:(?)y/(?)t=-b((?)y/(?)x)。(1)式中 y 为高度;t 为时间:x 为位置,以距分水岭的长度来表示;b 为正常数。这个方程显然是描述坡面随时间变化而平行后退的现象,故 b 被称为“后退系数”。

Open Journal of Preventive Medicine 2014年第1期4卷 41-49页

作者： Selena A. Hunter Alice McLachlan Takayoshi Ikeda Michael J. harrison Duncan C.

background: The teaching of the sensitive examinations—i.e. that of the female breast, female pelvis, female and male rectum and male genitalia—is a challenging part of the undergraduate curriculum. There are no studies to date detailing how national and international medical schools teach all of these examinations. Purposes: This research sought to document the teaching strategies used by national and international medical schools regarding the sensitive examinations. Methods: The sensitive examinations surveyed are the: 1) Female breast;2) Female pelvis;3) Male genitalia;4) Female and male rectum. The term “female sensitive examinations” is used to refer to female breast and female pelvis examinations. This was a questionnaire study, which polled national New Zealand medical schools as well as international medical schools. Questions included: a) sensitive examination teaching method;b) stress reduction strategies;c) perceived graduating student confidence. Results: A total of 104 medical schools participated in this survey in 2010. Artificial manikin usage was the most common technique utilized for each sensitive examination (60% of all schools, 95% CI 55%-65%), whether as the sole teaching method or in combination with other methods. The next most common technique was teaching associates (49% of schools, 95% CI 44%-54%). The female breast and pelvis sensitive examinations used the teaching associate program more frequently than the male genital examination and female and male rectal examination. Regardless of teaching method, most schools believed their graduating students were confident. Stress management teaching was used in most schools, in conjunction with teaching associate sessions. Conclusion: Manikins were the most commonly used teaching component of a teaching programme on sensitive examinations. Irrespective of teaching method, most schools believed their students were confident upon graduation.
