Magnetic force transmission of a reciprocating motion is studied by theoretical analysis and experiment. A mathematical model for calculating the magnetic force is derived using the theory of equivalent magnetic charges. An experimental rig is constructed to test the transmission and the model is verified by experiment. Effect of the transmission parameters on the magnetic force is analyzed theoretically from the model, and characteristic of the transmission is studied experimentally. Since the transmission is without direct contact between two elements, it is suitable for application in an organism.

未成年人司法转处制度是支撑未成年人刑事司法非刑化原则的核心制度,不应把这一制度泛化为少年司法的理念或主义,也不应只将其作为附条件不起诉的同义语。根据相关国际刑事司法国际准则的规定,借鉴其他国家或地区的经验,它是融程序和措施为一体的综合制度,构建全面合理的该制度就必须赋予警察和检察官更大的自由裁量权,把这种权力溶入到警察对微罪自行处置、酌定不起诉、附条件不起诉三种转处方式中,并且制定多样化的观护措施。

危岩块体的失稳多表现为突发崩塌破坏,无明显位移特征,因此常规位移监测难以达到监测预警的目的,此外影响危岩块体稳定性重要参数之一的危岩块体与母岩粘结面积难以获得,导致危岩块体稳定性评价困难。本文以危岩块体为研究对象,假设危岩块体均质各向同性,主控结构面为单个平面,系统阻尼比小于1,在振幅范围内的变形为线弹性变形,则可将危岩块体振动模型简化为弹簧振子模型。通过理论推导建立了危岩块体固有振动频率、危岩块体与母岩粘结面积、弹性模量和危岩块体质量之间的关系,再结合极限平衡模型,建立了基于固有振动频率的危岩块体稳定性评价模型。以白河堡水库右岸的危岩块体为试验对象,利用无线振动传感器(微芯方),将采集到的数据采用傅里叶变换等数学方法得到危岩块体固有振动频率,再结合固有振动频率与危岩块体粘结面积、弹性模量、危岩块体质量之间的关系,计算出块体粘结面积,最后基于该模型完成危岩块体稳定性评价。试验验证了基于固有振动频率的危岩块体稳定性评价可行性,相比传统方法更加快捷、准确。
