1) Stable and efficient spike
稳定有效穗数
3) panicle number per plant
单株有效穗数
4) effective panicle
有效穗
1.
25 t/hm2 of variety restorered by SH527;in principal component analysis,the first principal component of variety restorered by SH527 is effective panicle and number of filled grain per panicle and the 3 factors of yield play important role together in yield.
25 t/hm2外,其余几个系列产量水平相当;在主成分分析中SH527系列品种的第一主成分因子是有效穗粒数因子,而产量构成因素三者与产量之间的直接通径系数相近,说明三者对产量的作用都相当,这说明当其穗粒数达到一定高度时,穗数因子又成为新一轮产量增长的限制因素。
5) steady efficient viscosity
稳定有效粘度
1.
The concepts of steady working-point and steady efficient viscosity of hydraulic system were put forward according to the Vogel viscosity-temperature equation,providing new method and basis for determining reasonably the viscosity calculation value of hydraulic oil.
以静压轴承和液压滑环的简化模型———旋转对称环形缝隙为例，结合Ｖｏｇｅｌ 粘温方程，提出了液压系统稳定工作点和液压油稳定有效粘度的概念，为合理地确定液压油粘度值提供了新的方法和依据。
6) relative-stable efficiency
相对稳定有效性
1.
Based on principle of mean-variance, firstly, this paper deals with the definition of therelative-stable efficiency of stochastic DMUS, builds the model DEA, analyses the relative-stableefficiency and gives the result of calculating for the practical example.
基于均值-方差原理,提出了随机条件下决策单元相对稳定有效的概念,建立了随机DEA模型,分析了其相对稳定有效性并给出模型的求解方法。
补充资料：有效位数
对没有小数位且以若干个零结尾的数值,从非零数字最左一位向右数得到的位数减去无效零的个数;对其他十进位的数,从非零数字最左一位向右数而得到的位数就是有效位数.
