摘要
在山区的窄深河道断面上按《河流流量测验规范》要求制定测流方案时,可能会遇到断面概化垂线流速分布形式参数1/n_(11)值超越《河流流量测验规范》"Ⅱ型误差表"或"地区综合Ⅱ误差表"中1/n_(11)的取值范围,在这种情况下为了正确引用Ⅱ型误差表中的数据,需分析1/n值对Ⅱ型误差的影响程度以及变化趋势。
When drawing up testing flow project, according to the request of river ＇Flow Festing Standard＇, in narrow, deep course river segnent mountain area, it maybe encounters cross section perpendicular line current velocity, distributing parameter 1/n, overstepping, ＇Ⅱ Type Error＇ in ＇River Flow Testing standard＇ or the value scope of 1/n in the Area Integration ＇ Ⅱ Error Table＇. In this situation,in order to cite data in the Ⅱ type error table,we need to analysis value 1/n causing the influnce degree and changing tendency to the Ⅱ type error.
