Data application corresponding data amendment mathematical model is modified, and obtains accurate data.
Further preferred technical solution, one millimeter of cigarette is a list when microwave density instrument detects cigarette density
Position.
Further preferred technical solution, it is 4-8 that the cigarette, which needs the quantity of modified detection unit,.
Further preferred technical solution, described that the intermediate truncation of the same cigarette is obtained two sections, when cutting, lights from A
The whole millimeter in centre at B point cutting.
Further preferred technical solution, the end A and end B are exchanged, and measurement is pair twice before and after the density value of A point
Answer same millimeter cigarette.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is the feature accurate using the microwave density instrument detection non-end data of cigarette object, and foundation institute is in need to repair

In a kind of typical embodiment of the application, as shown in Figure 1, it is close to provide microwave density instrument detection cigarette end
The modification method of distortion is spent, including：
Cigarette detection：
First normal cigarette is put into the detection of microwave density instrument, is detected the end A first, obtains end detection data A1jd,
For distortion value, then, by cigarette, B point is cut off at the whole millimeter in centre lighted from A, and A, B are exchanged at end, CB, BA two after cutting
End is close to second of progress and measures, and is detected the end B first, obtains middle part detection data A1jz, is non-distorted value；
The density value of microwave density instrument output be from end one millimeter be a unit, the centre that when cutting lights from A
B point at whole millimeter, it is ensured that after end is exchanged, measurement is corresponding same millimeter cigarette twice before and after the density value of A point, no
Then, it does not ensure that.
By the method that first cigarette detects, i-th cigarette is detected, end detection data Aijd and middle part testing number are obtained
According to Aijz；
J is detection unit serial number, and for the integer from 1 to m, m is maximum distortion unit number, generally 4-8.
I is cigarette number, and for the integer from 1 to n, n numerical value takes 30-50.
