A predicted value of river water flow rate is output from the actually measured values Q(t) and ri(t) of river water flow rate sent from a river water flow rate measurer 5. In this case, the Q(t) is approximated to the secondary item  of Volterra series, and its integral nucleus is developed by Lagnerre polynomial. The  parameters of developing coefficient, developing item, time constant, etc., are determined by a square average error minimization method for actually measured value  and calculated value, and the error resulting from the difference between the amount  of rain water at points and the total amount of rain water is absorbed in the variable  of internal conditions. Thus, the accuracy of the prediction of the flow rate of river  water can be enhanced.

Filed: 1986-03-28
Abstract: PURPOSE:To obtain an optical recording medium having high sensitivity by laminating a recording layer consisting of a material which makes reversible phase transfer according to irradiation conditions of a light beam and reflective layer on a substrate. CONSTITUTION:This optical recording medium 1 is constituted by successively laminating the recording layer 5 and the reflective layer 7 on the substrate 3. The reflective layer 7 consists of any of metals among Cu, Au and Al. The recording layer 5 consists of the material which makes reversible phase transfer between an equi. phase and non-equil. phase according to the irradiation conditions of the laser beam. Such material is selected from various materials including simple substance of Te, GeTe alloy, TeIn alloy, etc. The light past the recording layer 5 among the laser beams irradiated from the substrate 3 side is fully reflected by the reflective layer 7 and makes multiple interference with the reflected light from the boundary face on the substrate 3 side, by which the quantity of the reflected light is largely changed. The recording sensitivity is thus improved. A dielectric layer may be interposed between the recording layer 5 and the reflective layer 7. The sensitivity is thereby improved.
