Cu-BTC/PVDF杂化膜的原位掺杂制备及增强的染料吸附性能

第十三届中国卫星导航年会

作者： Guoqiang Jiao Shuli Song Ke Su yangyang liu Shanghai Astronomical Observatory Chinese Academy of Sciences University of Chinese Academy of Sciences China Institute of Microelectronics of the Chinese Academy of Sciences

BeiDou Navigation Satellite System（BDS） on-orbit satellites contain BDS-2 and BDS-3 satellites. Due to the existence of ISB between BDS-2 and BDS-3 on receiver side, the traditional BDS precise clock estimation（PCE） and precise point positioning（PPP） models for the BDS-2 and BDS-3 combined processing will reduce the accuracy and stability of solutions. To improve the BDS service performance, the ISB between BDS-2 and BDS-3 for both old（B1 I/B3 I） and new signals（B1 C/B2 a） and its impact on PCE and PPP are investigated in this contribution. The BDS-2 and BDS-3 integrated PCE and PPP models with and without ISB estimation are presented. The combined processing is comprehensively assessed in terms of the precision of clock offsets and PPP performances. The result demonstrates that the ISB is stable for both old and new signals, and estimating ISB can effectively avoid the confusion of receiver clock datum. The integration of BDS-2 and BDS-3 indeed improves the precision of satellite clock offsets estimations based on the proper PCE models. The average STD for BDS-2 and BDS-3 clock offsets using old signals is improved by 15.8% and 11.1% compared with BDS-2-only and BDS-3-only solutions, respectively. For new signals, the improvement for BDS-3 clock offsets is 14.6% from 0.081 ns to 0.069 ns. The BDS clock offsets estimated by the proposed PCE model with ISB estimation（PCE0） can well support PPP applications. The positioning accuracy for old signals can be improved by 40.4%, 20.0% and 35.4% compared with those of using GFZ rapid products. Similarly, the positioning performance for new signals is slightly better than GFZ PPP. The PCE0 model is the optimal BDS-2 and BDS-3 integrated satellite clock offsets determination model for the server, and the PPP model with ISB estimation（PPP0） is the optimal PPP model for the client. The cooperation between PCE0 and PPP0 can improve the BDS service performance.

将Cu-BTC颗粒与聚偏氟乙烯(PVDF)溶液共混,原位掺杂制备了Cu-BTC/PVDF杂化膜,利用扫描电子显微镜(SEM)、X射线衍射仪、热重分析仪和傅里叶变换红外光谱仪等对杂化膜的结构进行了表征,并对杂化膜的亲/疏水性质、膜孔隙率以及膜水通量进行了测定,探讨了Cu-BTC的掺杂量对杂化膜结构和性质的影响.结果表明,Cu-BTC的存在使PVDF薄膜的成核机理发生改变,降低了PVDF膜孔尺寸,提高了膜表面亲水性和水通量.在对刚果红(CR)的吸附实验中,Cu-BTC/PVDF杂化膜表现出显著增强的吸附活性,且随着Cu-BTC掺杂量的增加,Cu-BTC/PVDF对CR的吸附性能逐渐增强.吸附热动力学拟合结果表明,吸附过程以Langmuir单分子层吸附和化学吸附为主要特征.

为避免航空施药过程中由于多施、漏施、重施等现象造成的覆盖不精准问题,该研究开发了一种航程短,覆盖范围精准的航空施药全覆盖航线规划算法。首先基于区域全覆盖原理,通过对施药作业区域外喷雾航程计算与分析,得出在全覆盖的前提下,区域外最短喷雾航程计算公式。再结合全覆盖航线规划方法,得出全覆盖航空施药的最优航线规划算法,并通过软硬件设计实现了实时采集飞行轨迹,通过OneNet物联网平台与移动终端进行信息双向传输。最后分别对3种不同地形的试验场地进行了7个不同航向的全覆盖喷雾作业试验。试验结果表明,在3种试验场地中,按照规划航向作业的航程比试验组按照其他6个航向作业的航程短,航程比其他航向的航程最大可分别缩短4.920、6.903、59.913 km;且多余覆盖率均为最小,多余覆盖率最小分别为2.08%、7.17%、0.57%。作业面积越大,规划航向作业的航程缩短越明显,多余覆盖率越小,并且规则地形航线规划的多余覆盖率明显小于不规则地形。所提出的航空施药全覆盖航线规划算法,可为航空施药航线规划技术的发展提供理论支撑,为实际施药作业提供指导。
