固体推进剂是火箭、导弹的重要动力源,其性能提高对提升导弹武器的作战能力具有重要意义.3D打印技术作为一项备受关注的先进制造技术,能够完成传统制造工艺难以达到的高精度、高复杂度的器件制造,解决传统固体推进剂浇注工艺难以解决的混料不均匀、产品一致性差、安全性低等问题,在固体推进剂制造领域具备广阔的前景.目前3D打印制备固体推进剂相关研究开展缓慢的原因主要是面临安全保障和工艺瓶颈两大难题.针对固体推进剂3D打印的安全性问题,将固体推进剂3D打印及其相关工作分成了部分含能组分3D打印、混合推进剂3D打印以及固体推进剂3D打印三个阶段,逐步论证其含能组分的安全可打印性.针对固体推进剂3D打印工艺瓶颈问题主要介绍了3D打印推进剂专用浆料、设备的开发进展.从目前已有的成果和发展趋势来看,未来的固体推进剂3D打印研究应该聚焦在专用配方的开发以及实现打印规模化两个方面.

Plant viruses are mainly transmitted by insect vectors in the non-persistent, semi-persistent, or persistent modes. In the non-persistent mode, plant viruses are retained in the stylets of their insect vectors. In the semi-persistent mode, plant viruses a
The various monochromatic Light Emitting Diode (LED) lights are widely used in growth facility for cultivating various plants, particularly horticultural crops because of their higher luminous efficiency, lower radiation and power consumption than the tra
Virus-induced gene silencing (VIGS) is a natural defense mechanism of plants, which can cause sequence-specific degradation of viral RNA and is often used for studying the functional genome. At present, the VIGS system mediated by Tobacco rattle virus (TR
Whole-genome shogun sequence (WGS) data generated by next-generation sequencing (NGS) platforms are a valuable resource for crop improvement. We produced 5–6 × WGS coverage of 44 Brassica oleracea breeding lines representing seven subspecies/morphotypes:
潘敏求教授认为肝癌的基本病机离不开“瘀、毒、虚”,创立了肝癌瘀毒虚论.其临证遣方用药宗“扶正祛邪”的治则,立健脾理气、化瘀软坚、清热解毒的治法,并研发出了治疗肝癌的基本方肝复方和中成药肝复乐.临证以肝复方灵活加减,获得了较好疗效.本文从“病机观”“治疗观”两个方面详细阐述潘敏求教授治疗肝癌的学术思想,并附验案,以飨同道.

Rootstocks have a significant influence on adaptation to biotic and abiotic stress conditions and quality of fruit. So, choice of rootstock for a specific growing region is an important decision for a grower to make when establishing a commercial citrus o
基于传统制造技术的“经典”结构质量大、疲劳薄弱部位多,难以满足未来战机的研制需求.基于增材制造技术特征优势开发的创新结构(三维承载整体结构、仿生构型结构、梯度金属结构、微桁架点阵结构)突破传统结构的束缚,具有轻量化、长寿命、低成本等特征,可大幅度提升机体平台品质,为未来新型战机研制提供有效的技术途径.本文以燃油管接头、环形散热器、三维框梁整体结构为例,阐述增材新型结构设计制造一体化开发全过程;对比原传统制造方案,可取得大幅度减重、成品率提升、疲劳薄弱部位减少等显著效益.此外,还探讨了光纤传感、建筑工程结构

采用一系列的微观组织观察与力学性能测试相结合的实验方法,研究喷射成形Al-Cu-Li合金在形变热处理过程中的微观组织演变以及力学性能.结果表明:喷射成形态铝锂合金中晶粒为典型的等轴晶;合金晶界处的粗大结晶相为Al7Cu2Fe相,晶粒内部细长的结晶相为AlCu相;经均匀化处理后,合金中晶界宽度减小且晶内元素分布趋于均匀;合金中只有少量呈块状的Al7Cu2Fe相和点状的AlCu相和AlZr相未溶解;固溶处理后合金晶粒组织仍然为等轴晶,且合金中有呈弥散分布的纳米级的第二相(β′相和δ′相)析出;与直接人工时效处
