--- Part 2: Weighing evaporators: Soil water evaporation measurement is to study the whole process of soil water and gas cycle and plant emission, and to study the atmosphere-water-plant-soil (SPAC) Comprehensive system, to explore the law of land surface water balance, for water resources calculation, flood control, production and confluence, hydrological forecast, large-scale project water resources demonstration, river channel Provide technical support for flood control impact assessment and flood control and drought relief of construction projects within the scope, so as to solve surface water problems through evaporation in areas without data Provide scientific basis for water resource calculation problem: Soil moisture evaporation measuring instrument Part 1: Hydronic Evaporators1 ScopeThis document specifies the requirements, test methods, inspection rules, signs and instructions for use of hydraulic evaporators in soil moisture evaporation measuring instruments Instructions, packaging, transportation, storage, etc: This document applies to the development, production, testing and use of hydraulic evaporators:2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, dated citations documents, only the version corresponding to that date applies to this document;
