题目两根相距d=0.20m的平行金属长导轨固定在同一水平面内,并处于竖直方向的匀强磁场中,磁场的磁感应强度B=0.2T,导轨上面横放着两条金属细杆,构成矩形回路,每条金属细杆的电阻为r=0.25Ω,回路中其余部分的电阻可不计。已知两金属细杆在平行于导轨的拉力的作用下沿导轨朝相反方向匀速平移,速度大小都是v=5.0m/s,如图所示。不计导轨上的摩擦。(1)求作用于每条金属细杆的拉力的大小。(2)求两金属细杆在间距增加0.40m的滑动过程中共产生的热量。(1995年全国高考题)这类“导电滑轨”问题,要涉及到法拉第电磁感应定律、磁场对电流的作用、金属杆…  相似文献

The Ph.D. versus the Ed.D.: Time for a decision   总被引:3,自引:0,他引:3  
In this study, U.S. institutions that offer doctoral programs in education were surveyed and institutional catalogues of the past decade were reviewed to determine trends regarding the Ph.D. versus the Ed.D. Results of the study showed that (a) there is no clear institutional movement toward one degree title or the other; (b) research universities are increasingly reluctant and comprehensive colleges and universities are increasingly likely to offer the Ed.D. as their only doctoral degree title, and (c) requirements for the two doctoral titles are remarkably similar, including competencies in research and statistics. Findings are discussed in relation to three common positions of those who favor the Ed.D. over the Ph.D.: (a) the professional school argument, (b) the unification argument, and (c) the autonomy argument. The article concludes with a call for increased national dialogue to strengthen the education profession by reducing confusion between its two doctoral degree titles.Russell T. Osguthorpe, Associate Dean of Brigham Young University's College of Education, has done research in special education, instructional design and technology, and teacher education. He is presently responsible for graduate programs, research, and technology in the College. Dr. Osguthorpe received his education at Brigham Young University. Mei Jiuan Wong, a doctoral candidate in the Department of Instructional Science, Brigham Young University, has done research on instructional design and technology and teacher education. She is currently completing her dissertation on decision making in instructional design.  相似文献
