    Q Value Evaluation of Groundwater Quality under Plains in the Lower Reaches of the Yarkant River by DENG Ensong, LIU Yujiang, MA Ningxin, HUANG Shunyong

    Published 2022-01-01
    “…Evaluating groundwater quality plays an important role in the rational use of groundwater resources and groundwater environmental protection in the later period.Among 35 groups of groundwater quality test data taken in Tumxuk City,a plain area in the lower reaches of the Yarkant River in Xinjiang,the groundwater quality of 32 groups is Class V.A comprehensive evaluation model of groundwater quality is established by principal component analysis (PCA) with ten factors exceeding thresholds of Class V as evaluation indexes,including turbidity,total hardness,total dissolved solids,sulfates,chlorides,sodium,nitrites,fluorides,cadmium,and lead.Further,this paper proposes the method of calculating the Q value of groundwater quality and the fine classification standard of Q value,on the basis of which the groundwater in Class V can be sub-classified into V<sub>1</sub>—V<sub>4</sub> classes.The evaluation results show that the groundwater quality in 2,24,and 6 groups is V<sub>2</sub>,V<sub>3</sub>,and V<sub>4</sub>,respectively. …”

    A Birandom Job Search Problem with Risk Tolerance by Guoli Wang, Wansheng Tang, Ruiqing Zhao

    Published 2012-01-01
    “…Since the offered wages are random variables and the search process is random, it's impossible to obtain the job searcher's real return; in this case, its expected value can be calculated via birandom theory. Simultaneously, some propositions on the expected return as well as the average search times are also studied which may provide some valuable suggestions to the job searcher. …”
