Energy channel counting redistribution process and method for gamma spectrum analysis

The invention relates to an energy channel counting redistribution process and method for gamma spectrum analysis. The energy channel counting redistribution process and method for gamma spectrum analysis comprise the following steps of: determining two line segments, which are mutually parallel and equal in length, wherein the two line segments are respectively named AB and MN; MN represents an integer energy channel; AB represents a non-integer energy channel, and is original data; separating the AB line segment into multiple energy intervals, and selecting midpoints in the middle parts of the energy intervals, wherein both endpoints and midpoints of the various intervals are nodes; and the nodes are identified by letters; separating the MN line segment into multiple target intervals, and identifying the endpoints of the target intervals by letters; and, selecting the endpoint of the corresponding target interval, making a vertical line towards the line segment AB, identifying the pedal on the line segment
