从美军观察组看抗战后期美国对中共政策     

雍婷婷 《齐齐哈尔师范高等专科学校学报》2011,(1):107-108

1944年美国向延安派遣了一个军事观察组,代号＂迪克西使团＂,与中共取得了直接的接触,但是,美军观察组的派遣,并不意味着美国放弃片面的扶蒋联共政策,开始对中共进行军事援助,而是试图以联合中共作为向蒋介石施加压力的手段,以促使蒋改革内政,成为控制中国的唯一政治力量,避免中国内战的爆发,从而达到控制中国及保持远东稳定的目标。  相似文献   

Metaphor——A Tool for Writing     

周自强 《海外英语》2011,(10):22-23,26

Figurative speeches, especially metaphors that prevail essays, novels, reports, poems, etc. give flavor, if not life, to writings, help express the inexpressible, bring the abstract concrete, make the tedious succinct, and illuminate the vague and the ambiguous bright and clear. It seems that metaphors to writing is what salt to cooking ─ and more. In this paper, we are attempting to drag it to a "down-to-earth" tool to be handy to common learners by quoting examples from various styles to show how it can be used to increase language power and how important it is for ordinary Chinese learners of English to get familiar with and learn to employ metaphors and other figurative speeches in writing. We should be able to use words in non-literal sense to lend force to an idea, to heighten effects, or to create atmosphere, so as to make our writings eligible at least for practical use and readable for an ordinary native speaker of English.  相似文献

Ultrasonic tomography and its applications in oilfield     

钟兴福  吴应湘  李东晖  李强  王兴国 《浙江大学学报(A卷英文版)》2005,6(12):1420-1423

INTRODUCTION Oil and water well is an important basic estab- lishment in oilfields. In many oilfields, there are many different damages in the well’s casing walls after its development for a period of time. They will affect the normal production of damaged wells and adversely influence the neighbouring wells and the block, and threaten steady production. There are different kinds of damages due to multiple problems in the casing walls, for example, corrosion, perforation, decreased diame…  相似文献   

Exit cards: creating a dialogue for continuous evaluation     

Mazna Patka  Jennifer Wallin-Ruschman  Tenille Wallace  Candice Robbins 《Teaching in Higher Education》2016,21(6):659-668

This study explored the use of Exit Cards, which are formative evaluations of student knowledge and instruction undertaken at every class meeting. Its results are based on Exit Card data from two undergraduate research methods courses. Thematic analysis indicated that students used Exit Cards to communicate (1) what they learned, (2) challenges with course material, (3) experiences with peers, (4) requests for help, (5) challenges with coping, and (6) successes. While the present study is an initial exploration of the use of Exit Cards, it contributes to knowledge on the utilization of informal formative assessments.  相似文献

从工具价值理性到道德价值理性－－当代新科技条件下科学技术性质的转换     

刘雪丰 《湖南师范大学社会科学学报》2003,32(2):11-14

科学技术的性质如何，不仅应有横向的剖析，还要有纵向的梳理，才能提出接近真理的判断。从历史发展的视角看，大体可以划分为三个阶段：轻视科学技术阶段、积极运用科学技术阶段和自学控制科学技术阶段。与当代新兴科学技术的特点紧密相联系，以当代新兴科学技术与首先的内在联系为基石，科学技术从工具价值理性走向道德价值理性，进路的关键在于，提升科学工作的良心和道德责任感，强化企业的外部伦理约束和自我道德限制，使国家随之成为对科学发展和运用进行全局的、长期的战略规划与管理的综合性实体。  相似文献   

基于有限元的护套线剥线机刀架疲劳强度分析     

康鹏桂  彭善飞  周克媛  张科 《北京工业职业技术学院学报》2020,(1):15-17,41

应用SolidWorks软件建立护套线剥线机主传动机构刀架三维实体模型,根据剥线机工作时的受力情况,利用有限元软件对刀架进行静力学和疲劳强度分析,获得刀架各项静力学参数图和疲劳寿命情况。该分析结果为护套线剥线机的设计提供理论依据,也为后续剥线机结构优化提供了技术支持。  相似文献
