Based on increasingly grim situation of carbon emissions in China,air pollution control and carbon emission reduction are very important. Therefore,combining with China’s specific national conditions,we should explore the market mechanisms to control air pollution and reduce carbon emissions in China. The achievement of the carbon emission reduction purpose needs to establish the carbon trade market based on intensity emission reduction and suitable for China’s national conditions. By setting the cross-industry,cross-region and cross-time carbon trade scenarios in China,this paper tries to study the market mechanism of carbon intensity trade among industries and regions and based on carbon finance mechanism.

Wheat cadmium(Cd) contamination is one of the environmental and agricultural concerns worldwide. Here, the effects of applications of foliar selenium(Se) and soil amendments(lime, mixture of biofuel ash and sodium sulfide(DSO), and mixture of iron mine tailing and alkali lignin(MX)) on soil Cd fractions and wheat Cd accumulation were studied using laboratory incubation, greenhouse pot, and field plot experiments. In the laboratory incubation experiment, lime and MX applications significantly increased soil pH, DSO application significantly decreased soil p H, while all the three amendments significantly reduced soil bioavailable Cd fractions by 16%–21% compared to the control without any amendment. Foliar Se application significantly increased the growth and yield of the high-Cd-accumulating cultivar(Puxing5). In the greenhouse experiment, lime and MX applications considerably decreased grain Cd concentration by 55% and 47%, respectively, for Puxing5 and by 24% and 26%, respectively, for the low-Cd-accumulating cultivar(Zhoumai30). In the field experiment, grain Cd concentration was significantly reduced by 68% and 72% by lime and MX applications, respectively, for Puxing5. Application of DSO also significantly reduced grain Cd concentration by 58% for Puxing5 and 25% for Zhoumai30 in the greenhouse experiment, but increased grain Cd concentration by 22% for Puxing5 in the field experiment. Our results implicate that laboratory incubation and greenhouse experiment results are necessary to be verified in field, and foliar Se application is recommended when considering both financial costs and production safety.

To reduce the experimental uncertainty in the 235 U resonance energy region and improve the detection efficiency for neutron total cross section measurements compared with those obtained with the neutron total cross section spectrometer(NTOX), a dedicated lithium-containing scintillation detector has been developed on the Back-n beam line at the China Spallation Neutron Source. The Fast Scintillator-based Neutron Total Cross Section(FAST) spectrometer has been designed based on a Cs2Li La Br6(CLLB) scintillator considering the γ-ray flash and neutron environment on the Back-n beam line. The response of the CLLB scintillator to neutrons and γ-rays was evaluated with different 6Li/7 Li abundance ratios using Geant4. The neutron-γdiscrimination performance of the CLLB has been simulated considering different scintillation parameters, physical designs,and light readout modes. A cubic 6Li-enriched( > 90%) CLLB scintillator, which has a thickness of 4-9 mm and side length of no less than 50 mm to cover the Φ 50 mm neutron beam at the spectrometer position, has been proposed coupling to a side readout SiPM array to construct the FAST spectrometer. The developed simulation techniques for neutron-γ discrimination performance could provide technical support for other neutron-induced reaction measurements on the Back-n beam line.

Particle filtering （PF） algorithm has the powerful potential for coping with difficult non-linear and non-Gaussian problems. Aiming at non-linear, non-Gaussian and time-varying characteristics of power line channel, a time-varying channel estimation scheme combined PF algorithm with decision feedback method is proposed. In the proposed scheme, firstly the indoor power line channel is measured using the pseudo-noise （PN） correlation method, and a first-order dynamic autoregressive （AR） model is set up to describe the measured channel, then, the channel states are estimated dynamically from the received signals by exploiting the proposed scheme. Meanwhile, due to the complex noise distribution of power line channel, the performance of channel estimation based on the proposed scheme under the Middleton class A impulsive noise environment is analyzed. Comparisons are made with the channel estimation scheme respectively based on least square （LS）, Kalman filtering （KF） and the proposed algorithm. Simulation indicates that PF algorithm dealing with this power line channel estimation difficult non-linear and non-Gaussian problems performance is superior to those of LS and KF respectively, so the proposed scheme achieves higher estimation accuracy. Therefore, it is confirmed that PF algorithm has its own unique advantage for power line channel estimation.

研究了两个供应商在同一平台进行销售时的渠道模式选择问题。考虑产品差异性,通过修正的Hotelling模型构建了产品竞争需求函数,并运用斯塔克伯格博弈和纳什博弈,分析了转售、混合和代理三种不同渠道模式下的均衡定价及利润,并在此基础上进行比较分析。研究结果表明,竞争产品差异越大,平台及供应商可实现的均衡利润越大。同时,平台与供应商形成何种渠道模式取决于代理费用比例的大小,当代理费用比例足够小时,平台倾向于代理而供应商倾向于转售;当代理费用比例足够大时,平台倾向于转售而供应商倾向于代理;当代理费用比例处于中间一定区间取值时,平台与供应商倾向于采取混合模式。
