2) abnormal period
非正常期
1.
Since the clear and neat cavity profile of aluminum electrolysis cell is the prerequisite to high efficient and stable operation of cell,the paper mainly sets forth the importance and indicates that better cavity profile of cell depends on the reasonable keeping of technical conditions under abnormal period and the maintenance under normal production.
良好炉膛建立取决于非正常期技术条件的合理保持,正常生产期间规整炉膛的保持和维护。
3) normal tour
正常任期
4) normal moveout
正常时差
1.
The stack method after normal moveout is not effective.
本文针对因存在噪音和信号比较弱 ,致使正常时差 (NMO)校正迭加方法难以奏效的问题 ,提出提高信噪比和增强反射信号同相轴连续性的共反射面元 (CRS)迭加方法 。
2.
In view of the situation that normal moveout correction stack method could not work very well for the low signal to noise ratio, we give an enlarging common reflection surface stack method to raise signal to noise ratio and enhance reflect wave s continuity.
因此 ,针对因地震资料的信噪比较低而导致常规的正常时差校正叠加方法难以奏效的情况 ,提出了提高信噪比和增强反射波连续性的扩大反射面元叠加方法。
6) normal hours
正常小时
补充资料：正常（超导）—超导（正常）转变
正常（超导）—超导（正常）转变
transitionfromnormal(superconducting)statetosuperconducting(normal)state
一般指在常压下改变温度到Tc时，物质的电阻从R＞0（R=0）的正常态（超导态）到R=0（R＞0）的超导态（正常态）的转变。无磁场时这种转变属二级相变。
