增值税作为我国第一大税种,其收入再分配效应在很大程度上事关税制公平。国际增值税立法趋势表明,近年来国外增值税标准税率基本稳定,同时各国比较重视民生领域增值税税率的调整,通过低税率、零税率以及免税等方式,克服增值税的累退性... 详细信息

增值税作为我国第一大税种,其收入再分配效应在很大程度上事关税制公平。国际增值税立法趋势表明,近年来国外增值税标准税率基本稳定,同时各国比较重视民生领域增值税税率的调整,通过低税率、零税率以及免税等方式,克服增值税的累退性。为实质性发挥增值税对收入分配的调节作用,平衡增值税税率与国民经济发展的互动关系,有必要进一步简并税率。可能的路径是为普通货物和服务分别设置一档增值税标准税率,并为与民生相关的货物和服务设定相同的优惠税率,以助力我国共同富裕的推进。

By simply switching the electrical circuit installed on steel/steel contact,the tribological behaviors of nanofluids(NFs)can be regulated in real time,thereby achieving the desired performance of friction reduction and wear ***,solvent-free carbon spherical nanofluids(C-NFs)were successfully prepared for intelligent lubrication regulation.C-NFs with excellent lubrication performance can immediately reduce the coefficient of friction(COF)despite applying a weak electric potential(1.5 V).Moreover,polyethylene glycol 400(PEG400)containing 5.0 wt%C-NFs remained responsive to electrical stimulation under the intermittent voltage application with an average coefficient of friction(ACOF)reduction of 20.8%over *** intelligent lubrication regulation of C-NFs under an external electric field(EEF)mainly depends on the orderly arranged double-electric adsorption film of ion canopy-adsorbed carbon spheres(CSs).The intermittent electrical application can continuously reinforce the adsorption film and its durability for real-time controlling the sliding ***-stimulation-responsive intelligent lubricants provide a new technical support for realizing intelligent stepless control of devices.

激素性股骨头坏死滑膜病变分子机制的实验研究

2020年中国地球科学联合学术年会

作者： Chen Qiong yang xiaoqiang Zhao Jianxin Shandong University Sun Yat-sen University University of Queensland

Changes in Southern Hemisphere(SH) high-latitude temperature have been proposed to influence the Asian monsoon(AM) variability on the millennial timescales. Asian monsoon derived from stalagmites in the Northern hemisphere clearly responded to the early Last Interglacial(LIG) warming in the Antarctic. However, the variability of the Antartic signal in propagation to the low latitude in the Northern Hemisphere remains unclear. In conjunction with the Antarctic Circumpolar Current,
