Reformation of electronic automatic balance display and recording instrument 电子自动平衡显示记录仪表的改造
Development of Automatic Inspecting and Recording Instrument for the Water 水质自动监测记录仪的研制
The flow production and sediment production and their processes were studied in the paper based on the data from observation in runoff plots for many years and from simulated rainfall experiment, using an automatic runoff recording instrument made by ourself. 通过对径流小区的多年观测和人工模拟降雨试验,利用自制的径流自动记录装置,研究了油松林地不同处理的产流产沙及其动态过程。
