Analysis of Green Technology Upgrading Strategy Based on Collaborative Incentive of Environmental Policy and Green Finance

With the continuous development of economy, the bottleneck problem of environmental resources has become increasingly prominent. Enterprise environmental governance technology innovation incentive has become an important issue for the development of government, society and enterprises. Under the control of enterprise's expected economic target, this paper discusses the synergistic incentive effect of environmental policy and green finance on enterprise's environmental governance technology innovation decision by using nonlinear programming model. The results show that when the funds for environmental governance technological innovation are insufficient, there is an optimal decision space to use green financial loans to implement technological innovation and upgrade, and then achieve the expected economic goals; Under a given level of environmental governance technology, environmental policies affect whether enterprises can make decisions on technological innovation and upgrading of environmental governance; Green financial mechanism will not. However, when the enterprise makes the decision of environmental governance technology upgrading, it will affect the enterprise's decision on green financial loan amount. The results of the study have guiding significance for the formulation of environmental policy and green financial policy, as well as the decision-making of enterprise environmental governance technology innovation and upgrading.     

结构损伤识别的周期小波方法

通过对结构损伤前后模态特征的变化进行分析,利用损伤结构的位移振型函数构造出曲率振型函数γi(x),然后再在曲率振型函数的基础上提出一个用于探测和评定损伤程度的新指标———损伤因子r(x)=∑i∈Idγi2(x);基于小波分析的方法,对损伤因子进行周期小波变换,通过小波系数的取值范围提出了一种结构损伤定位和损伤程度的评估方法.数值仿真表明,这是一种行之有效的损伤识别方法.     

镍(Ⅱ)四磺酸基酞菁修饰玻碳电极制备一氧化氮传感器

用电沉积法将镍(Ⅱ)四磺酸基酞菁(NiTSPc)修饰在玻碳电极表面,又用浸蘸法将Nafion修饰在该电极表面,制备出一种新型一氧化氮电化学传感器,并研究了它们对缓冲溶液(PBS)中一氧化氮(NO)和亚硝酸盐(NO2-)的电化学行为.实验结果表明,NiTSPc和Nafion修饰材料对一氧化氮分子的电化学氧化具有显著的促进作用,在c(NO)为0.2~8μmol/L的区间内,用NiTSPc和Nafion修饰的传感器的DPA电流值与c(NO)成良好线性关系,且灵敏度高,选择性良好,可用于NO实时检测.

Optimal pricing and inventory policy with order cancelations under the cash-on-delivery payment scheme

Considering a periodic review system where the online seller allows the customers to pay when the products are delivered to them（referred as cash-on-delivery payment scheme in this paper）,the authors investigate the seller＇s joint pricing and inventory control policy with a finite planning horizon.In particular,the authors incorporate the customers＇ possible order cancellation behavior with the cash-on-delivery scheme.It can be proven that the base-stock list price policy is optimal under mild conditions.The authors also analyze the impact of the customers＇ forward looking behavior on the optimal policy.
