[Method] Based on the data of haze and sunshine duration from 11 counties or cities in Dezhou City from 1970 to 2009, the daily, monthly, seasonal and annual variation of haze and their variation reasons were studied, meanwhile, the effects of haze on sunshine duration were discussed. [Result] Haze occurred most frequently from 09:00 to 14:00 and daily variation was different in various seasons; haze days were the most in December (200 d), and next came January (161 d), while hazes days were the fewest in August (20 d). From seasonal variation, haze appeared most frequently in winter, accounting for 40% of that in total year, autumn (23%) and summer (20%) the second, and haze days were the fewest in spring (18%). For annual variation, haze days were the fewest from 1970 to 1979 (110 d) and most from 2000 to 2009 (724 d), with the tendency rate of 2.27 and 16.35 d/a, respectively. From regional distribution, haze days were the most in Decheng District, and next came Xiajin, while Yucheng had the fewest haze days. In addition, the annual variation of haze days was related to pollutant concentration in atmosphere, while monthly variation and seasonal variation were controlled by weather situation and meteorological condition. [Conclusion] The study could provide scientific reference for the prevention and impact assessment of haze.展开更多

[ Method] The data of body weight, body size and sexual behavior of male donkey during production were collected, combining with the semen quality data of ejaculation volume, density, motility and frozen-thawed semen motility were conducted the statistical analysis. [ Results] ( 1 ) Single ejaculation volume had a positive correlation with body height (r = 0. 423, P = 0. 044) and penis circumference (r = 0. 495, P = 0. 043 ) , and total number of sperm per ejaculate had a positiw: correlation with body weight (r = 0. 444, P = 0. 036) and scrotal circumference (r = 0. 520, P = 0. 039) ; (2) Ejaculation volume was negatively correlated with mount times (r = -0. 159, P = 0. 035) and erection time (r = -0. 181, P = 0. 023), semen density was negatively correlated with mating time (r = - 0.211, P = 0.004), and total sperm count was negatively correlated with erection time (r = - 0. 159 , P = 0. 047). [Condusion ] The quality of semen had a certain correlation with body size, body weight and sexual behavior.展开更多

Two scenarios(a business-as-usual (BAU) scenario and a CO_(2) mitigationscenario (CMS)) are set up. The results show that in theBAU scenario, the final energy consumption will peak at25.93 million tons of coal equivalent (Mtce) (16% growthversus 2014) in 2030. In the CMS scenario, the finalenergy will peak in 2020 at 23.47 Mtce (9% lower versuspeak in the BAU scenario). The total primary energyconsumption will increase by 12% (BAU scenario) anddecrease by 3% (CMS scenario) in 2030, respectively,compared to that in 2014. In the BAU scenario, CO_(2)emission will peak in 2025 at 70 million tons of carbondioxide (MtCO_(2)), and subsequently decrease gradually in2030. In the CMS scenario, the peak has occurred in 2014,and 60 MtCO_(2) will be emitted in 2030. Active policiesincluding restructuring the economy, improving energyefficiency, capping coal consumption, and using more low・carbon /carbon free fuel are recommended in Dezhou citypeaked CO_(2) emission as early as possible.展开更多
