在绿色发展理念新时代背景下,为深入研究21世纪以来中国绿色发展中产业政策与环境政策的融合问题,以2003—2021年中国“绿色产业政策”文本为研究对象,构建政策横向协同、纵向协同和可持续性三维度的协同分析框架,量化分析了中国绿色产业政策协同状况。研究结果表明:中国绿色产业政策年颁布数量和总效力持续上升,但政策平均力度与平均效力有待提高;政策部门协同力度不断增强、未来协同空间依然较大;政策目标协同度持续提升,绿色市场与其他政策目标协同有待强化;政策措施协同度上升趋势近年来有所减弱,标准引领与其他措施协同有待加强。

A dynamic parallel forecasting model is proposed, which is based on the problem of current forecasting models and their combined model. According to the process of the model, the fuzzy C-means clustering algorithm is improved in outliers operation and distance in the clusters and among the clusters. Firstly, the input data sets are optimized and their coherence is ensured, the region scale algorithm is modified and non-isometric multi scale region fuzzy time series model is built. At the same time, the particle swarm optimization algorithm about the particle speed, location and inertia weight value is improved, this method is used to optimize the parameters of support vector machine, construct the combined forecast model, build the dynamic parallel forecast model, and calculate the dynamic weight values and regard the product of the weight value and forecast value to be the final forecast values. At last, the example shows the improved forecast model is effective and accurate.

The real-time measurement and reconstruction of three-dimensional temperature are essential when studying the combustion process inside a flame. In the proposed sectioned flame light field imaging model, flame sections are reconstructed based on the characteristics identified using the Lucy-Richardson or nearest neighbor filtering methods, or a joint method involving a combination of both, to improve on the accuracy of two-dimensional temperature reconstruction. Compared to the results of a previous work, the proposed method increases the resolution in the depth of field direction and the extraction of the flame temperature of all sections from the same height ensures the accuracy of the reconstructed temperature distribution across the cross-section of the flame. The relative error when compared to the actual flame is less than 10%. Thus, this approach allows the accurate estimation of the three-dimensional temperature distribution inside a flame, and enables the rapid and effective reconstruction of the three-dimensional temperature field.

Nowadays, using a solar-driven thermochemical reaction system to convert greenhouse gases into high-quality liquid fuels has been proven to be an effective way to address the growing depletion of traditional fossil fuels. However, the utilization of highlyconcentrated solar irradiation runs the high risk of reactor damage issues resulting from thermal stress concentration, which seriously threatens the security and reliability of the total reactor system. In this study, the thermal radiation distribution and thermo-mechanical process in a volumetric reactor were numerically investigated by combining Monte Carlo ray-tracing method with computational fluid dynamics method. Based on the experimental results and thermal characteristic analysis, the formation mechanism of thermal stress concentration and the strategies of improving thermal stress distribution were discussed in *** simulation results indicate a great possibility of reactor damage at about 1000℃ operating temperature and 9.0 k W lamp power, which is well-matched with related experimental results. The ceramic damage typically occurs at the inner edges of the through-holes, including the aperture, the gas inlet, and the thermocouple hole, then extends along the lines connecting these holes and finally causes brittle fracture. By reasonable control of the opening direction and the distance between the throughholes, the maximum compressive stress can be reduced by 21.78%.

发动机吞鸟试验是检验航空发动机安全性和可靠性的重要手段,为了探究在发动机吞鸟试验中,鸟体出膛后飞行轨迹的变化,优化抛鸟策略,采用动网格技术,使用六自由度模型对鸟体出膛后的轨迹进行计算分析。结果表明:鸟体出膛后,其肩部会形成一个高压区域,尾部形成一个低压区域,由此产生气动阻力,在运动方向阻力最大,在飞行过程中阻力会稳定在某一数值;运动方向垂向和横向所受气动力很小,但数值波动较大,且变化无规律;鸟体飞行过程中速度衰减小,弹道平直,可以采用直瞄的方式将鸟体抛向指定的位置。
