Field test data collected over the 6-month period in 2006 were employed to compare the effectiveness of three sward riparian buffer zones for reduction of runoff SS and removal of nutrients in the leachate and to estimate the buffer zone width for achieving 80% SS reduction(optimal width).
34mg/L,也均低于GB3838—2002Ⅴ类标准规定的限值;3种草皮缓冲带径流水SS去除率和沿程距离具有显著的相关性,在径流水SS去除率为80%时,通过计算可知3种草皮缓冲带的最佳宽度为16。
补充资料:为半高宽
分子式:
CAS号:

性质:又称为半高宽。在吸收谱带高度最大处高度为一半时谱带的全宽。带宽的量纲是长度的倒数(波数)或时间的倒数(频率),因此这个数值也可以表示能量的大小。此术语应与半带宽相区别,后者指带峰高极大处半高处带宽的一半。
