自动闭塞设备监测系统的设计与实现
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 2
Abstract
本文设计一个监控铁路闭塞情况的系统，通过软件动态生成通讯接口，可以满足实际中站间区间数量不相等情况对设备的要求；通过数据采集和串行口通讯，实时地采集闭塞区间的占用情况，并实现了从数据采集到传输、分析、判断、加工处理及存储的自动化及故障检测和故障定位的智能化，对提高铁路闭塞区间的通过能力和故障检测能力有积极的意义。

回波平面成像中ghost伪影的校正
EPI技术基于方向相反的频率读出梯度交替采集MR信号的奇、偶回波。但是，由于成像物体的磁敏感性、化学位移及磁场B0不均匀性等因素的影响会导致奇、偶回波之间产生相位移动，因而会产生ghost伪影。本文首先用混合空间投影的方法消除部分伪...

苹果酸辅助法水热合成ZnS∶Mn的相态<br /> 及其远红外吸收光谱的研究<br />
采用苹果酸辅助法水热合成了ZnS∶Mn。随着络合剂——苹果酸的加入量从0 g，0.2 g，1 g增大到2 g，苹果酸与锌离子和锰离子形成的络合物有效控制了金属离子的释放速度，调节了ZnS∶Mn晶体的生长速度，因此，ZnS∶Mn的形貌规整度逐渐提高，其晶相...
