Furthermore, the results were applied to the relative inverse eigenvalue problem, and the minimum norm solution for the inverse eigenvalue problem was presented. 同时也把所得结论应用到相应的逆特征值问题,并给出了逆特征值问题的极小范数解。
According to the results of empirical study, current relative corporate value is in inverse proportion to asset return ratio and asset liability ratio, and in direct proportion to equity interest and long term / short term liabilities; 实证结果表明,我国上市公司当前的相对价值与公司的资产报酬率以及资产负债比呈反比,而与公司的股东权益比、长短期负债比成正比。
For which the inverse problem of the thermal parameters of concrete can be taken as a problem to be optimized and get the relative fast convergence solutions in the inverse calculation for identification of the thermal parameters of concrete through simulated annealing algorithm. 混凝土热学参数反演问题可作为一个优化问题,经比较模拟退火优化算法能够在混凝土热学参数识别的反演计算中得到相对快速的收敛解。
To gain better estimates of relative treatment effects in the presence of selective crossover, we used inverse probability of censoring weighted ( IPCW ) modeling. 采用逆概率删失加权分析(IPCW)模型以更好地评估转换治疗的相对治疗效果。
Technical parameters and characters of sampling system determine that seismic wave amplitude recorded by seismograph is approximate relative amplitude. Using these data necessarily leads to serious distortion of inverse parameters. 采集系统特性和技术指标决定了所记录的地震波振幅值为近似的相对振幅,用这样的相对振幅作为地震波参数反演的振幅真值依据,必然导致反演参数值的严重失真。
