| Abstract: | by application and the curve of the muhinomial fitting temperature to the specific gravity bottole and the total water mass, the total mass of the bottle and water of each specific-gravity bottle at different temperature is calculated by the mtdtinomial equation derived. This method is quicker and more precise. Verified by comparison tests at site, this method satisfies accuracy and improves work efficiency. |
