positive column

Methods By using analytical column, electrospray ionization and positive ion monitoring components of kitasamycin were analyzed.

方法采用分析柱, 以电喷雾电离、正离子检测,以确定吉他霉素各组分.

Finally, the positive column is reached where electrons and ions have equal densities.

最后到达的区域是正柱区,这里,电子和离子具有相等的密度.

Positive 4 out columns, and column and the rafter head still painting marks.

正面4棵明柱, 柱梁及椽头尚有彩画痕迹.

One bare steel joint and two cruciform composite joint specimens were tested under low cyclic loading at the top of columns so that one side of the beam-to-column connections was under negative moment and the other side under positive moment.

进行了一个纯钢节点、两个组合节点的低周反复荷载试验。采用柱顶水平加载模式，连接的一侧承受负弯矩，而另一侧承受正弯矩。

Positive locks for table, head, quill, column.

为表, 头, 鹅毛笔, 列正锁.
