Time series of MODIS land surface temperature(Ts) and normalized difference vegetation index(NDVI) products,combined with digital elevation model(DEM) and meteorological data from 2001 to 2012,were used to map the spatial distribution of monthly mean air temperature over the Northern Tibetan Plateau(NTP). A time series analysis and a regression analysis of monthly mean land surface temperature(Ts) and air temperature(Ta) were conducted using ordinary linear regression(OLR) and geographical weighted regression(GWR). The analyses showed that GWR,which considers MODIS Ts,NDVI and elevation as independent variables,yielded much better results [RAdj2> 0.79; root-mean-square error(RMSE) =0.51℃–1.12℃] associated with estimating Tacompared to those from OLR(RAdj2= 0.40-0.78; RMSE = 1.60℃–4.38℃).In addition,some characteristics of the spatial distribution of monthly Taand the difference between the surface and air temperature(Td) are as follows. According to the analysis of the 0℃ and 10℃ isothermals,Tavalues over the NTP at elevations of 4000–5000 m were greater than 10℃ in the summer(from May to October),and Tavalues at an elevation of3200 m dropped below 0℃ in the winter(from November to April). Taexhibited an increasing trend from northwest to southeast. Except in the southeastern area of the NTP,T d values in other areas were all larger than 0℃ in the winter.

Is Cannabis a boon or bane?Cannabis sativa has long been a versatile crop for fiber extraction(industrial hemp),traditional Chinese medicine(hemp seeds),and recreational drugs(marijuana).Cannabis faced global prohibition in the twentieth century because of the psychoactive properties of △^(9)-tetrahydrocannabinol;however,recently,the perspective has changed with the recognition of additional therapeutic values,particularly the pharmacological potential of cannabidiol.A comprehensive understanding of the underlying mechanism of cannabinoid biosynthesis is necessary to cultivate and promote globally the medicinal application of Cannabis ***,we comprehensively review the historical usage of Cannabis,biosynthesis of trichome-specific cannabinoids,regulatory network of trichome development,and synthetic biology of *** review provides valuable insights into the efficient biosynthesis and green production of cannabinoids,and the development and utilization of novel Cannabis varieties.

干热岩储层水力压裂形成复杂缝网对于建设增强型地热系统(EGS)至关重要。为了深入认识干热岩储层水力裂缝扩展机制,揭示工程参数和地质参数对水力裂缝扩展的影响规律,本文以青海共和盆地某干热岩储层为研究对象,基于扩展有限元(XFEM)数值模拟软件ABAQUS展开研究,建立现场尺度的干热岩储层模型,实现热流固耦合分析水力裂缝的扩展机制。结果显示:正断型应力状态下,裂缝发生了很明显的朝向Z轴的转向,走滑型应力状态下,裂缝扩展主要沿水平方向,有轻微倾向于Z轴转向的趋势,逆冲型应力状态下,裂缝沿水平方向扩展;随着弹性模量的增大,裂缝的起裂压力减小,裂缝延伸的注水压力也减小,弹性模量越大裂缝起裂的时间越早,泊松比越大水力裂缝的破裂压力越大,破裂压力整体呈现出正断型>走滑型>逆冲型;随着温度的升高,水力裂缝破裂压力减小,大约降低2~3 MPa左右,3个应力状态下都呈现出相同的趋势。本文丰富了干热岩水力裂缝扩展的数值模拟手段,相关研究成果可为干热岩储层中水力压裂扩展预测与不同参数对其的影响分析提供技术支撑。

三维地质模型建设在地质环境评价、深部地质找矿以及城市地下空间开发与安全利用方面扮演着越来越重要的作用,其技术突破为透明城市和智慧城市的发展提供了重要的地质支撑。青岛市作为滨海基岩型城市的代表先后采用剖面交互式建模、Bentley MicroStation v8i平台建模、显式构造界面建模和隐式建模四种方法探究三维地质模型建设方法的优劣,得出显式构造界面建模方法是目前最为成熟的建模方法,模型建设效果较好,但修改更新困难;隐式建模方法发展较晚,模型更新速度较快,结合实际地质情况调整和完善算法后会成为未来的主流建模理论方法。此外,三维地质建模标准地层和模型尺度的约束不够明确,应尽快出台相应规范进行说明。

粗煤泥分选是选煤过程中的重要环节,传统的粗煤泥分选设备对难选粗煤泥难以实现有效分选,因此选煤厂通常采用两段分选来满足产品要求,但两段分选工艺比一段分选工艺复杂。为简化粗煤泥分选工艺流程,以TPS和TBS在回坡底矿选煤厂的工业应用为例,对比了两种设备在自身结构、产品结构和分选效果上的差异。在设备结构上,TPS通过在分选桶内增加一个内桶实现了两段分选,并通过顶水分配装置和内桶溢流导流槽等结构优化保证了两段分选的可靠性。在产品结构上,TBS可分选出精煤和矸石两种产品,但无法同时获得合格精煤和高灰分尾煤;TPS不仅可获得精煤、中煤、矸石三种产品,而且可根据产品质量要求灵活调节出两产品或三产品,在精煤产品灰分合格的前提下TPS尾煤灰分为72.21%,同时可得到产率为36.62%、灰分为35.72%的中煤产品。在分选效果上,TPS的数量效率比TBS高2.82个百分点,可燃体回收率比TBS高24.53个百分点。TPS与TBS分选粗煤泥的对比研究可为TPS与TBS的合理选型提供有益参考。
