Through the tests on gas driving water and water driving gas, the flow law of gas and water was real-time observed. Mainly based on the test of water driving gas as an example, the development of molding coal sample and NMR triaxial osmoscope was demonstrated. The experiment process of water driving gas and parameters were demonstrated. NMRI images of molding sample in horizontal cross-section along the driving direction were obtained by NMRI instrument. The results from images were analyzed and compared. Some novel laws were obtained as the following:(1) the leading edge of water driving has inconsistency. This certified the important previous conclusion that the storage of methane mainly was absorbed in inner surface of pore from NMRI technique;(2) the existence of dominant driving pathway was tested and the way kept almost fixed. The pathway is apt to exist in the edge of coal samples where pore and fracture fully develop;(3) the variation of water flow determines the transport velocity of leading edge of water driving and it has lag effect;(4) the effectiveness of the first driving is better than the second driving;and (5) the subsequence of water driving gas are from trunk fractures to branch fractures, then to branch pores.
主要以水驱气NMRI试验为例,详细介绍了核磁共振三轴渗透仪和型煤试件的研制,并重点阐述了水驱气试验过程和相关参数,利用NMRI技术实时观测得到了不同时间沿驱替方向型煤试件水平剖面的NMRI成像图,最后对试验结果进行了比较分析,揭示了一些新的规律认识:(1)水驱替前缘具有不一致性,从NMRI试验角度验证了前人甲烷类气体赋存形式主要以吸附在孔隙内表面为主的重要结论;(2)煤试件存在优势驱替路径,且这种优势路径在驱替过程中基本保持不变,水驱气的优势驱替路径易产生在煤试件边缘,即煤孔隙裂隙发育区;(3)水驱流量变化决定了水驱前缘的运移速度,且对水驱气效果具有滞后效应;(4)水驱气初次驱替效果好于二次驱替效果;(5)水驱替气的顺序为:主要大裂隙—周边裂隙—周边孔隙。

Driving force of wheel on soft lunar soil is much different with wheel on the ground of the earth.Wheel sinks and slides easily on lunar soil.The driving force formula of wheel based on Bekker formula is much complex,for forecasting driving force,curve fitting based on least squares method was introduced to simplify formula driving force.The driving force can be calculated through measuring wheel sinkage and slide.
基于Bekker轮-地力学理论的车轮驱动力计算公式复杂,不适合直接计算,为实现车轮驱动力预测,为车轮驱动力优化提供计算基础,本文采用基于最小二乘法的数据拟合方法对车轮驱动力进行数值拟合计算,为实时的车轮驱动力预测提供可行的方法,从而实现对车轮驱动力的优化。

The Fourth Medicine came into being with the health revolution, the fourth great revolution. In the development history of human beings, each scientific and technical revolution has greatly influenced people's life: the Agricultural Revolution has put an end to the dog-eat-dog age and solved the problem of food and clothing; the Industrial Revolution has greatly improved the efficiency, making people enjoy a comfortable life while work for a shorter time and the Information Revolution has shortened the time and space, providing more leisure time for people. At present, people are faced with the health revolution, aiming to make people have a pleasant, healthy, longevous and high-quality life. To meet that end, the fourth medical workers need to make great efforts. The Fourth Medicine contains scraping and cupping therapy, stone needle therapy, massotherapy, foot massage, body beauty, psychology, physiotherapy, reasonable movement and food therapy, etc.
第四医学的形成是在人类的第四次大革命健康革命启发下而诞生的在人类历史的发展中,每次科学技术革命,无不给人类的社会生活带来巨大影响,农业革命使人们不必自相残杀,弱肉强食,人人可以温饱地生活;工业革命使劳动效率大大提高,使人们在短时间的劳作就可以安逸舒适的生活;信息革命又使时空缩短,大大提高了劳动生产率,使人们的休闲时间大大超过了劳作时间当前所面临的是人类的第四次大革命健康革命它的目标使人们愉快健康长寿,高质量地渡过幸福的一生要想达到这一目标就需要第四医学工作者来完成第四医学包含了刮痧拔罐疗法砭石疗法按摩疗法足疗美容心理学理疗合理运动食疗等
