According to the result, the confidence region of unknown parameters in single-index models is constructed. Finally, we consider the test of correlation and heterogeneity for hierarchical nonlinear mixed-effects models.

Safety injection actuation test was performed at Full-scale Simulator of QinshanⅡNPP, the initial condition for the test was same as one for the SI actuation test of Unit 1 during commissioning. SI signal was triggered by low-low steam pressure through opening the steam dump valves to atmosphere. Comparing the results obtained from the simulator and real data from the commissioning of Unit 1 showed that the results from the simulator were more conservative from view points of safety, so the models and parameters for the simulator were credible.
