| Abstract: | In order to measure the seed coefficient of diametrical less, has designed the system which composes, based on the XDII multipurpose signal generating device and the National VP-5512 oscilloscope, applied the high-frequency circuit determination seed confident of diametrical loss, to definite between coefficient of diametrical loss and output voltage functional relation, provided the determination seed coefficient of loss which is impale. This method has the high sensitivity, the stability and the good dynamic characteristic, divinely may sissify the seed coefficient of dialectical loss measure request. |
| Keywords: | agricultural engineering seed coefficient of dialectical loss design containing water rate electric capacity sensor |
