光的本质是横波电磁波矢量,以双向反射分布函数BRDF (bidirectional reflectance distribution function)为基础模型的标量遥感体系只利用植被反射光的整体强度信息,无法进一步区分反射辐射蕴含的叶表、叶内和冠层结构信息;在标量遥感基础上考虑垂直于电磁波传播方向的二维偏振矢量特性(强度+方向)就能深化为矢量遥感体系,从而有望精确刻画反射光中蕴含的多种信息,提升植被参数反演精度.刻画偏振反射空间分布的双向偏振分布函数BPDF目前存在精度低、泛化性差等问题,因此进一步探索矢量遥感基础理论,构建通用性强的植被矢量遥感基础模型具有迫切的现实需求.本文旨在利用光子与植被元素的相互作用构建通用性较强的植被BPDF物理模型.首先基于光子–植被元素相互作用的光谱不变原理,提出基于方向逃逸概率的植被BPDF物理模型基础形式,并基于植被单次反射的辐射传输理论推导模型解析表达;随后通过考虑叶片散射随干物质含量的变化,提出光谱不变原理优化表达并推导模型通用表达式;最后分别利用三维矢量辐射传输模型和多尺度实测数据实现模型的正演直接验证和间接验证.结果表明,本文构建的BPDF物理模型的解析表达和通用表达在不同植被场景下,对偏振反射率的正演均方根误差可达0.001以内,与矢量辐射传输模型正演结果在半球空间内具有很强一致性,在多尺度实测数据也简洁验证了模型关系的稳定性,模型R2普遍高于0.9.相比于现存植被偏振反射模型,本文构建的模型兼具物理机理、简洁形式、可接受的参数化方案、较高精度和较强泛化能力,对浓密植被具备通用性,为在BRDF一维标量遥感的基础上进一步考虑BPDF二维偏振特性从而形成矢量遥感体系这一转变过程提供了理论基础和探索性方案.

针对辅助谐振变换极型逆变器在换流时缓冲回路损耗大这一问题,在一种改进型谐振极逆变器的基础上提出一种改进控制策略。与原控制策略相比,该控制策略不仅能够实现所有主、辅开关管的软开关,而且可将换流时流过缓冲回路的电流最大值控制在换流时刻的负载电流值,避免换流时缓冲回路的谐振电流与换流时刻的负载电流相叠加,从而可有效降低缓冲回路在换流时的环流损耗以及辅助管的电流应力。在改进控制策略下,根据不同工作模式下的等效电路图,分析该逆变器的工作原理、软开关实现条件以及最佳参数设计方法。最后使用IGBT作为开关器件制作一台10kw、16kHz样机,通过实验验证该控制策略的有效性。

利用类二噁英类多氯联苯(PCBs)大气氧化降解产物二羟基多氯联苯与2,3-二羟基联苯双加氧酶(Bphc,PDB ID:1kw6)进行分子对接,构建以分子结构参数为自变量,对接打分函数(K_d,代表对接活性)为因变量的分子相似性指数分析(Co MSIA)与分子全息定量结构-活性相关关系(HQSAR)模型,并对二羟基多氯联苯进行分子修饰,研究结果表明,Bphc酶对二羟基多氯联苯均有不同程度的降解能力,影响Bphc酶对接活性的氨基酸残基为His145,Val147,Ile174,His194,His208,His209,His240,Asn242,Tyr249及Thr280,且二羟基多氯联苯与氨基酸残基对接形成的氢键越多对接活性越高.建立了CoMSIA和HQSAR模型耦合的二羟基多氯联苯分子取代活性精确定位方法,以打分函数较低的二羟基多氯联苯5,6-2OH-CB60为目标分子,设计出8种打分函数显著提升的新型分子,其对接活性提高65%~185%,分子毒性(IC_(50))下降10%~83%,生物富集性(BCF)下降4%~27%,迁移性(K_(OA))与半衰期(t_(1/2))增降幅基本不变.所设计新型分子反应路径的推断可以验证二羟基多氯联苯5,6-2OH-CB60在环境中与活性自由基或与活性分子反应生成所设计的新型5,6-2OH-CB60分子,即类二噁英类PCBs可通过大气氧化降解最终生成酶降解性显著提高的新型二羟基多氯联苯,达到进一步控制类二噁英类PCBs环境行为的目的.
