Humans have relied on biomass for survival and development since the Stone Age. All aspects of human needs for materials are covered by tools, fuel, and buildings. Nowadays, metals and petroleum-based materials are widely used in highly developed industries. Unfortunately, environmental contamination and the loss of natural resources have led to the reemergence of biomass resources as efficient and sustainable energy sources. Notably, simple and direct applications can no longer meet the demand for functionalization, high performance of materials and construction materials. Therefore, it is imperative to modify biomass and combine its utilisation to produce functionalization and high performance materials. For example, construction materials with superior mechanical properties and water resistance can be produced by reinforcing fibres to facilitate crosslinking. Water-oil separation or adsorption effects of hydrogels and aerogels are determined by the porosity and lightness of biomass, biocomposite conductor is prepared by chimaeric conductive material. Here, we review the approaches that have been taken to devise an environmentally friendly yet fully recyclable and sustainable functionalised biocomposites from biomass and its potential directions for future research.

针对由多个细胞星构成的组合卫星的姿态控制问题,提出了一种包含控制力矩计算层与冗余力矩分配层的双层姿态控制方法。将细胞星间的冗余力矩分配问题转化为群体博弈的策略选择问题,综合考虑能量消耗、飞轮输出力矩裕度和飞轮角动量裕度设计收益函数,以力矩分配系数作为群体质量,以细胞星作为策略建立群体博弈模型。考虑群体演化中模仿和比较形成的不同演化策略,分别采用Smith动力学以及复制器动力学修订协议求解博弈的Nash均衡解,并利用有限制策略的群体博弈理论形成分布式冗余力矩分配方式,得到各个细胞星的控制策略。最后通过仿真实验验证了此分配方式的有效性。

由于海面和海底两个强波阻界面的存在,海洋地震资料普遍发育强能量多次反射波,海洋多次波衰减贯穿着整个海洋地震资料处理的始终,是影响海洋地震资料成像品质最主要的因素之一。复杂海域情况下的多次波压制往往需要通过多方法多域分步组合的衰减策略,计算耗时而且多域多步骤会造成计算误差的累计,从而影响多次波的衰减效率和精度。为此,提出了一种基于自注意力机制对抗网络(SA-GAN)的海洋多次波压制方法。首先,针对特征数据利用多域分步组合法压制多次波获得标签数据集;其次,在U-Net生成器网络中引入自注意力机制(SA),构建基于SA-GAN网络的多次压制深度学习模型,并进行网络训练;最后,利用训练完备的SA-GAN网络对整体数据进行多次波压制处理。引入SA的U-Net生成器的GAN网络收敛速度快且计算稳定,在地震样本数据集上具有更好的数据泛化能力。与常规方法相比,本文提出的方法只需人工处理少量特征数据,网络训练后便可进行工区大量数据的多次波压制处理,避免了复杂多次波压制多方法串联组合的繁琐过程,为海洋实际地震数据的多次波压制提供了一种高效手段。模型和NH探区深水实际资料处理结果验证了本方法的有效性。
