Under the premise of the Earth’s layer structure and mass distribution, the solid inner core cannot be stable in the center of the sphere. Thus, the deviation of the inner core is towards the sphere’s center and the liquid outer core must have asymmetrical thermal convection. Based on the two suggestions, a concise and self-consistent global motion model can be built. The model consists of the following cycle: an asymmetrical thermal convection structure in the outer core led by the dislocation of the inner core→the plume is in special upwell position because of differential activation→the formation and split of lithosphere→the split plates drift and assemble in a new location, the mass of which causes the inner core to deviate towards this direction again→the new asymmetry is formed. As this circulation continues, a definite and periodical motion emerges/forms. Its nonlinear features result in the Earth’s motion with simple mechanisms but complex behavior. Ultraterrestrial events may disturb or

本文以南京马尧海等人"换偶"一案的审判结果以及学术界的争论为背景,论证聚众淫乱行为入罪的正当性和合理性。任何一种行为入罪必须满足法益侵害性、违反伦理性和惩罚必要性三个条件。聚众淫乱行为可以满足这三个条件,因此应当治罪。但是,由于社会的发展和人们观念的改变,我国立法中的聚众淫乱罪确有修改完善的必要。为此,本文建议将聚众淫乱罪设置为情节犯,以在维护秩序和保障人权方面达成平衡。

目的探讨足球或者排球运动对男性大学生骨密度的影响力,为提高大学生体质状况和骨质疏松症的防治提供理论参考和实践支撑。方法在河南工业大学、河南大学民生学院和郑州成功财经学院按自愿原则共招募研究对象196名,全部为汉族男性,其中大学生足球运动员42名,排球运动员54名和普通大学生100名,对上下肢、髋部和全身骨密度进行测量。结果足球运动员和排球运动员相关部位骨密度均高于普通大学生,排球运动员上肢骨密度高于足球运动员和普通大学生,足球运动员下肢骨密度高于排球运动员和普通大学生(P值均<0.05);足球运动员的右侧下肢骨密度[(1.34±0.13) g/cm]高于左侧[(1.30±0.12) g/cm],而排球运动员右侧上肢骨密度[(0.74±0.09) g/cm]高于左侧[(0.69±0.08) g/cm](P值均<0.05)。结论足球或者排球运动均能提高男性大学生的骨密度,且2种类型运动对骨密度的影响具有部位特异性或不均衡性以及方向性不对称的特点,造成此结果的原因可能与骨骼所受的力学刺激有关。

王杖制度源于周代"齿杖制度",以鸠饰杖是由原始先民的鸟图腾崇拜演变而来。从周代的"献鸠养国老"到汉代的"助食养老",鸠杖的权杖功能不断弱化,养老寓意逐渐形成。汉代王杖制度进一步使之法律化、制度化。尹湾汉简所记授杖人数应为东海郡当年度新授杖人数,而非东海郡授杖总人数。

介绍了北京冬奥会延庆赛区水资源供需情况,并对水资源利用方案进行比选。基于完整年尺度的水资源分析显示,延庆赛区奥运年需从外部调水57.09×10^(4)m^(3),其中地表水47.11×10^(4)m^(3),自来水9.98×10^(4)m^(3);非奥运年需从外部调水16.35×10^(4)m^(3),全部为自来水。基于逐日分析的水资源利用方案显示,非奥运年再生水系统与融雪水、雨水系统分设方案再生水回用率仅为26.01%,远低于再生水、融雪水、雨水系统统一调蓄方案再生水回用率(56.85%),从水资源管控、景观环境营造、场馆运营等方面进行对比,再生水、融雪水、雨水系统统一调蓄方案对水资源的管理更为高效。
