“…The t test is used to evaluate the effect of an independent variable on the dependent variable by a testing if an SRC significantly differs from zero. For that purpose, the null‐hypothesis is that the SRC is equal to zero, and the conclusions are given in terms of the probability of rejecting a true null‐hypothesis 15,19,27 . Accordingly, a prediction model composed of parameters that significantly influence the observed output can be derived by removing unimportant parameters.…”

Summary The trip setpoint parameters of a molten salt reactor have been analyzed by performing multiple linear regression (MLR) method. In the analysis, a reactivity‐initiated accident with inadvertent control rod withdrawal accident under low power condition was considered as the initiating event. A total of 285 cases located from 20 235 thermal‐hydraulic simulation runs have been divided into identification dataset (70%) and test dataset (30%) for MLR. MLR models show that the maximum fuel salt temperature and corresponding control rod extraction rate follow a quite convincing linear hypotheses relationship with trip setpoint parameters. Sensitivity analysis gives the sensitivity rankings of trip setpoint parameters. And the predictive values of three significantly influential trip setpoint parameters with different margin considerations have been acquired quantitatively.

“…MLR is wildly used in various fields. It is also adopted to analyze parameter sensitivity of a reactor passive safety system 14,15 . During the analysis, MLR was performed to study the relationship between accident consequences, reactivity insertion rates, and trip setpoint parameters.…”

“…In addition, we derived the grain prices from 2001 to 2020 from the "The National Compilation of Cost-benefit data of Agricultural Products" as a reference (Table 1). To make a scientific evaluation of the value of cropland resources, we established three accounting accounts [34]: the physical quantity account, the conditional account, and the monetary account [35][36][37][38]. Among them, the physical quantity account was used to reflect the changes in the number and scope of cultivated land in the study area from 2000 to 2020, and to provide necessary data for value accounting, while the quality account was used to record the quality status of cultivated land in the study area.…”

Cultivated land resources are important natural resource assets that are related to food security and sustainable development. Due to the many restrictive factors of the karst landform on agricultural production, the quantity and quality of cultivated land in the karst mountainous areas in Southwest China are poor. Reclaiming cultivated land to develop economy or to avoid transitional reclamation to protect ecology is an important proposition in this area. Analyzing changes in the physical and monetary value of cropland resources can help us to formulate more reasonable policies for the development and utilization of cultivated land resources, and to achieve a win-win scenario for economic development and ecological protection. Using multi-source remote sensing data and 20-year landcover data obtained by the GEE platform, this paper evaluated the cropland resources of the karst mountain areas of China at the pixel level. It was found that under the apparent outflow of the physical account of the cultivated land resources, the monetary value still maintained growth, proving that the current cultivated land-use policy in Guizhou Province has significantly improved the value of local cultivated land resources.
