The purpose of this study was to find out the relation between visceral adipose index (VAI) levels and stress urinary incontinence (SUI) in adult women.
Responses of Potamogeton crispus in turion germination,seedling growth and leaf photosynthesis efficiency were studied in 2 pot culture experiments.The winter experiment had six treatments with controlled light,i.e.2×104-5×104(CK,maximum light intensity at noon),350-450,160-260,60-80,30-50,and 0-30 lx,and lasted 67 days from January 20th to March 28th of 2007.And the summer experiment was carried out in a light incubator,also with six treatments,various in light intensity,that is,1 400,970,660,450,160 and 120 lx,to study light threshold of turion germination under high water temperature in summer was studied.Results show that(1)light intensity had no significant effects on turion germination,which completed on D45 in the winter experiment,while in the summer experiment,light intensity threshold was found to be in the range of 120-160 lx,and over 90% of the turion germinated under the light intensity of 1 400 lx;(2) at the early growth stage,the P.crispus seedlings displayed a higher growth rate(about 1.20 cm·d-1)in the 5 treatments than in CK(0.92 cm·d-1),and a reverse trend at the late growth stage,that is,about 1.09 cm·d-1 in the treatments and 3.15 cm·d-1 in CK,and moreover,the number of leaves of the seedlings in the treatments did not increase with the growth of P.crispus in plant height;(3)in the winter experiment,beginning on the 39th day after the germination,maximal photochemical efficiency of PSⅡ(Fv/Fm),quantum yield of PSⅡ(ΦPSⅡ)and photochemical quenching(qp)of the plants declined with decreasing light intensity,and the effect of dim light on PSⅡ of P.crispus was significant,whereas,non-photochemical quenching(qn)increased,protecting PSⅡ of P.crispus leaves;and(4)long-term exposure to dim light seriously affected the light corresponding capacity of the seedlings.
Based on the analysis of the scale effect on land use classification area of land use survey,this paper puts forward the calculation method of the areal difference of the same land types under different scales,so as to lay the theoretical basis for the further study of the areal difference of the current situation of large scale land use survey.
Based on lithological statistics and core observation of a large number of wells,sedimentological analysis of outcrops,and seismic facies analysis,four lithofacies paleogeography maps with a system tract as a unit were prepared for Feixianguan Formation of Induan Age of Lower Triassic in Sichuan Basin and adjacent areas in a 3rd-order sequence stratigraphic framework by synthesizing regional geological data such as plate tectonic evolution.These demonstrated that Kaijiang-Liangping Basin mainly deposited in the 1st and 2nd Members of Feixianguan Formation,and evolved into intra-platform depression in the 3rd Member of Feixianguan Formation.In addition,the maps showed distribution and migration characteristics of oolitic shoals in the basin during different periods,and platform margin oolitic shoals were found in the outcrops of Mianzhu(periphery of the basin) and Lichuan(Hubei Province).Together these findings provided evidences for oolitic gasfield exploration in Sichuan Basin.The oolitic shoals were widely distributed in each system tract of Feixianguan Formation in Sichaun Basin,with largest oolitic shoals found in the main gas-producing zones,i.e.,TSQ1-HST(2nd Member of Feixianguan Formation) and TSQ2-TST(3rd Member of Feixianguan Formation).The oolitic shoals showed continuous migration from the intra-platform to the basin facies.In the TSQ1-TST(1st Member of Feixianguan Formation),oolitic shoals were mainly distributed in the intra-platform paleotopographic highland and littoral zones,with small-scale oolitic shoals(bars) formed on the rimmed platform margin along both sides of Kaijiang-Liangping Basin.In the TSQ1-HST,oolitic shoals(bars) were concentrated along both sides of Kaijiang-Liangping Basin and platform margins of southwestern Chengkou-E'xi Basin.In the TSQ2-TST,large-scale oolitic shoals were developed in the northern and eastern Sichuan.In the TSQ2-HST(4th Member of Feixianguan Formation),oolitic shoals were locally distributed and formed through the sedimentation of restricted platform and evaporite platform.The main favorable exploration zones of the Lower Triassic Feixianguan Formation in Sichuan Basin are the dolomitized platform margin shoal facies along Kaijiang-Liangping Basin,and the dolomitized platform margin shoal facies along the southwestern Chengkou-E'xi Basin and dissolved intra-platform shoal facies.
