| Abstract: | (For PT.1 see I BID 1987 (1) P.45)This thesis reports the second period research and production of the electromagnetic wave gauge of soil moisture. During this period, the instrument has teen improved, so that the accuracy has been increased. Again and again, three different wave lengthes of electromagnetic wave have been used to test the samples of three kinds of different soil simultaneously. The results of the experiment shows that different soil and different soil moisture decrease towards the different frequency of electromagnetic wave according to a regular pattern. her research. |
