电子管和阀门中电极的编号和单位名称
1.Scope and object
This recommendation IEC 60135:1961 applies to multi-electrodes tubes and valves,with the exception of cathode-raytubes.
It describes the system used for numbering the electrodes of the same type in multi-electrode tubesand valves and for assigning designations to the units of multiple-unit tubes and valves.
For tubes and valves made with two or more similar units,the numbering of the units is given as derivedfrom the basing arrangement.
This recommendation shall not be used to determine the basing arrangement of any type.
The designations determined from this recommendation shall also apply to other tube or valveelements,such as heaters,shields,etc.
2.Numbering of electrodes in single-unit tubes and valves
In single-unit tubes and valves having more than one electrode of the same type,such as in multi-grid tubes and valves,such multiple electrodes shall be numbered consecutively,starting with the onenearer the cathode.Thus,in the case of multi-grid tubes and valves,the grid nearer the cathodeshall be designated grid 1,the next outward from the cathode,grid 2,etc.Electrodes of the sametype,when located at the same distance from a common cathode and acting on the same electronstream,shall be designated by the appropriate number suffixed by A,B,etc.Thus,in the case oftwo independent co-planar grids No.1,one shall be designated as grid 1a and the other as grid 1B.

1. 范围和目的
本推荐适用于多电极管和阀，但不适用于阴极射线管。它描述了在多电极管和阀中编号相同类型的电极以及为多单元管和阀分配单位的系统。对于由两个或更多相似单元制成的管和阀，单位的编号是从基准排列中派生出来的。本推荐不应用于确定任何类型的基准排列。从本推荐中确定的指定应用于其他管或阀元件，如加热器、屏蔽等。
2. 单体管道和阀门中电极的编号
在具有多个相同类型电极的单单元管和阀中，如多栅管和阀中，这些多个电极应按顺序编号，从靠近阴极的电极开始。因此，在多栅管和阀的情况下，靠近阴极的栅极将被指定为栅极1，从阴极向外的下一个将被指定为栅极2，以此类推。当位于共同阴极的相同距离处并作用于相同电子流时，相同类型的电极应该由适当的数字后跟A、B等字母进行指定。因此，在两个独立的共面栅极1的情况下，一个将被指定为栅极1a，另一个将被指定为栅极1B。
