论文部分内容阅读
I arrived at Caltech in June 1986,with interests in both mineral physics and seismology.I was excited to either study mineral physics with Professor Tom Ahrens,or investigate great earthquakes with Hiroo Kanamori.Upon arriving,I decided seismology would be my path.I was particularly interested in Hiroo\'s work on earthquake size,from some papers I read as an undergraduate(Kanamori,1978,1983).In my first week,I met with Hiroo,and he asked me what my plan would be for studying great earthquakes.Well,I had no plan,no clue!He wisely noted that we are in need of more and better seismic data-which of course came during the decade that followed with the digital data explosion.Hiroo suggested I introduce myself to seismologist Don Helmberger next door-maybe he would have some interesting research projects for me to consider.

信息社会的各类信息,影响和改变着我们日常学习、生活方式.全新的信息技术在小学语文教学活动中不可或缺.新型冠状病毒疫情爆发时,开展的大规模线上教育,促使线上教育与线下教育相结合,不但催生了教育的多元融合,还营造出新型的教学环境,更能凸显学生的研究意识,进一步提升学生的信息素养.
I first met Don Helmberger when I visited Caltech in the spring of 1984 as a prospective graduate student.During that visit,I was immediately impressed by Don\'s unbridled passion for science,in general,and seismology,in particular.Don made me feel quit
乡土文化是根植于特定地域内,经过世世代代劳动人民的长期积累、沉淀而形成的物质或非物质的民间文化总和.乡土文化资源包括历史溯源、地理物产、文物古迹、民间艺术、风土人情等等.可以说,中华传统文化之所以如此精彩多样,乡土文化功不可没.如何充分挖掘和利用好乡土文化,筑牢文化之“根”,将其融入到高中德育过程中,理应是一线班主任凝聚思考、尝试探索的一个重要方向.
一、中职工业机器人课程开发背景rn(一)市场需求背景rn受制造业自动化改造需求影响,2020年中国、日本、美国、韩国和德国等主要国家工业机器人的年装机量合计占全球的72.9%以上.2021年全球工业机器人销售额达到144.9亿美元,其中亚洲销售额95.6亿美元.预计到2023年,全球机器人市场将恢复疫情之前的增速状态,销售额将有望突破176亿美元,其中亚洲仍将是最大的销售市场.
Arriving at the Seismo Lab in 1981,I first worked with Hiroo Kanamori on the seismotectonics of the New Hebrides(Vidale and Kanamori,1983)(I don\'t remember why).Then with Rob Clayton I worked on finite-difference methods of modeling seismic waves,speci
