In this paper, some problems on the evaporation of running sea-water are theoretically mentioned, and it is verified that the theory agrees very well with the observations.<BR>In the first part of this paper,(Vol.7 No.2) the author has chiefly mentioned a fundamental theory on the sloping salt field, that is (1) the relation between the depth and the mean velocity of running sea water,(2) the temperature rise of water which is controlled by the air temperature, relative humidity and wind velocity at a given height above the salt-field and the intensity of solar radiation,(3) the effect of the main temperature rise of running sea water and the valuable evaporation surface, while in a given location,(4) the relation between the concentration of salt and the change of the depth of water, and (5) the temperature of water at the source of the flow.<BR>In the second part of this paper,(Vol.7 No.3-4) some, experimental data on the sloping salt-field is reported and compared with the author's theory.<BR>Readers will easily find that the theory on the temperature rise of running water agrees very well with the observed data. The main temperature rise is about 6 meters or of the total length of the salt field. The effective part of the salt field is 75 or 80% of the whole surface.<BR>The author bas calculated here the thermal efficiencies which are defined by him to be 86-91%, and also estimated the leakage of water in the earth bed of the salt-field.
