Methods:Shellfish extract was preseparated and gathered by AccuBondⅡ SPE silica column extractor.
方法:贝样品提取液经AccuBondⅡSPE silica固相萃取小柱预分离和富集,用三级四极杆串联质谱(MS/MS)作为HPLC的检测器,使用正离子电喷雾(ESI)电离方式,多反应监测(MRM)扫描模式,选择母→子离子对m/z827→m/z723,m/z827→m/z809作为定量检测的离子对,HPLC的流动相为乙腈:1%甲酸-水(体积比70:30),色谱柱为Agilent Extend-C18(2。

According to the actual working conditions of bolting-shotcrete supporting in coal-mine tunnel,the working mechanism of different buckets was studied,their merits and demerits were analysed,and the double-crank grab bucket with assistant linkage was proved to be an ideal choice of grabbing materials in coal-mine tunnel because its motion trace was definite and symmetric and occupied lesser space.
从巷道锚喷支护中物料抓取的实际作业环境出发,对拟采用的几种抓斗的工作机理进行了分析研究,比较了各方案的优缺点,指出辅助连杆的双曲柄抓斗的运动轨迹确定、对称,且具有在竖直方向上占用空间最小的特点,是井下巷道施工中物料抓取的理想选择,这种设计方法能够为相关抓取装置的设计起到参考作用。
