＜正＞Herbicides inhibiting protoporphyrinogen oxidase （protox） have been commercialized for nearly 40 years. 2-（7-Fluoro-3-oxo-3,4-dihydro-2H-benzo-[b][1,4]oxazin-6-y1）-4,5,6,7-tetrahydro-2H-isoindoline-1,3-diones are a class of phenylimide protox inhibiting herbicides. The commercial product of this class is flumioxazin. In our previous work, we found a new compound B2055, which can be applied post-emergently as herbicide, and has better selectivity to crops than flumioxazin at the same dosage. However, the manufacturing cost for B2055 is higher

研究铸件几何特征对砂型铸造Mg-9Gd-3Y-0.5Zr(VW93)合金线收缩的影响。利用3D扫描仪精确提取自由收缩和受阻收缩砂铸件的尺寸,并用于计算收缩系数。引入砂芯体积与铸件包络体积之比(γ)量化砂芯对铸件收缩的约束程度。通过分析自由收缩系数的统计分布和受阻收缩系数随γ的变化规律发现,VW93合金的自由收缩系数为1.96%,受阻收缩系数随γ的增大而线性减小,此关系为根据铸件几何结构预测VW93合金收缩率提供支持。

在光晕区域附近进行光晕消除操作可能会降低图像的对比度、清晰度和细节。因此,需要开发有效的方法来恢复和增强光晕消除后的图像细节,以确保整体图像质量的提高,为此设计一种改进暗通道原理下视觉图像光晕消除算法。建立大气散射模型深度分析光晕产生条件,根据图像中的像素强度值计算成像环境中的透射率,按照大气光照的散射系数建立光照条件研究模型。在较高的像素颜色通道条件下,根据图像中高亮度和强反射部分搭建无光晕图像亮通道定义,聚类图像亮通道特征,利用快速双边滤波器细化透射率,建立光晕图像的成像模型。在改进暗通道原理的过程中通过调整多个计算参数,包括改变权重函数,设置光晕消除的恢复指令,完成对视觉图像的光晕消除处理。经过实验分析可以证明,所提方法具备良好的光晕消除性能,光晕消除效果较好。
