1) RVA(Range of Variability Approach)
变化范围法(RVA)
2) range of variability approach
变动范围法
1.
On the basis of a flow variation analysis,range of variability approach(RVA) is applied to analyze the hydrologic regimes of Yichang Hydrological Station before and after the impoundment of Gezhouba Reservoir and the overall degree of hydrological alteration is evaluated,then the hydrological regimes variation before and after Three Gorges reservoir impoundment is analyzed.
以梯级水库下游宜昌水文站1882-2006年流量资料为研究对象,采用Mann-Kendall法对宜昌站流量变化进行了趋势性分析,并采用复Morlet小波周期性分析,在此分析基础上采用变动范围法(RVA)分析葛洲坝水库蓄水前后宜昌站水文情势变化,定量评价了水文情势改变程度,随后对三峡水库蓄水前后宜昌站水文情势变化进行了分析。
2.
According to the Range of Variability Approach(RVA) proposed by Richter,a method using Indicators of Hydrologic Alteration(IHA) containing thirty-two eco-hydrologic parameters,the difference between the flows before and after 1967 was quantitatively evaluated.
采用Richter提出的变动范围法,基于包含32个水文参数的水文改变指标体系,定量评估了黄家港水文站1967年前后水文情势的变化。
3) Strain Range Partitioning (SRP)
应变范围区分法
1.
According to the character that for the high strength,low ductility alloys,the inelastic strains is small and difficult to determine,a modified method of Strain Range Partitioning (SRP) was presented.
用Rene'95材料650℃下控制应变的循环松弛试验数据对修正方法进行了验证,结果表明:对Rene'95材料的蠕变疲劳寿命,修正方法的预测能力好于应变范围区分法(SRP),对基本试验的寿命预测精度基本上在2倍范围之内。
4) calculus of variation in the large
大范围变分法
5) rational change range
合理变化范围
