In this work, low-temperature vulcanized, transparent silane modified epoxy resins for LED filament bulb package were prepared. Firstly, transparent silane modified epoxy resins were produced through a controllable sol-gel method using γ-（2,3-epoxypropoxy）propytrimethoxysilane and dimethyldiethoxylsilane. The features of the reaction were investigated and the products were characterized in detail. Subsequently, various curing agents were explored to prepare transparent silane modified epoxy resins. The silane modified epoxy resins cured by PEA-230 at a fairly low temperature（40 °C/2 h then 60 °C/1 h） exhibited excellent thermal stability with a thermal degradation temperature as high as 316.5 °C and adjustable hardness between 40-60 shore A. The application tests showed the materials obtained were good candidates for LED filament bulb package.

为提高工业机械臂对目标物体抓取及对障碍物躲避的效率和成功率,提出一种基于改进抓取信息引导的快速随机树星(GI-RRT^(*))的机械臂路径规划算法.首先,预先设定最大迭代次数和自适应函数,缩短机械臂运动轨迹生成时间,增强采样导向性和质量;其次,基于椭圆形子集直接采样,对采样点位置进行约束,提高采样效率;最后,采用贪心算法删除机械臂运动轨迹的冗余点,并使用三次B样条曲线平滑约束机械臂运动轨迹,提高机械臂运动轨迹的柔顺性.利用生成残差卷积神经网络模型预测,输入深度相机采集的彩色图像和深度图像,输出视场中物体的适当映射抓取位姿.为验证机械臂的抓取效果,选择三指气动柔性夹爪,设计柔性抓取模块,并结合法奥(FR3)协作机械臂构建自主抓取系统,进行二维地图仿真和机械臂样机实验.结果表明,与传统的信息引导的快速随机树星算法相比,GI-RRT^(*)算法运动轨迹长度缩短10.11%,轨迹生成时间缩短62.68%.同时,算法具有较强的鲁棒性.机械臂能独立地避开障碍物、抓取目标物体,满足其自主抓取的需求.

We have investigated the possibility of the presence of the deltas in neutron star matter and their effects on neutron stars. Δ-meson couplings of the theoretical predictions are only restricted in a region where the deltas can be present and even a first-order phase transition may take place, making the EOS sorer and the maximum mass of neutron stars smaller. The presence of the deltas leads to the rapid decrease of neutrino mean free paths.
