基本解釋

Book circulation rate is the important indicator that measures the quality of library collections and services, and there are many factors influenced it.

Both moisture content and salt content has a smaller dispersion alonge the border head to border tail by saline water surge flow irrigation, yield decreased significantly irrigated by saline water traditional surface border irrigation than that of surge flow irrigation. Both irrigation efficiency and irrigation uniformity were analyzed by SRFR Model, it showed that when the field slope gradient is 0.15%, border length is 200-250m, unit width flux is 3.0～4.0L/m. s, periodic numbers is 3, circulation rate is 1/3, water supply time in one period is 30 min, surge flow irrigation can obtain maximal irrigation degree.
