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、建筑工程结构等跨领域技术对战机结构创新的借鉴意义.

近年来,互联网移动医疗的发展呈现出快速上升的趋势,其在中医健康管理方面的应用价值也日益受到重视.中医药对于肺癌的防治具有显著的特色和优势,在我国肺癌的诊疗领域发挥了重要作用.我们基于互联网移动医疗,引入整体观念、辨证论治、体质、治未病与养生康复等中医核心思想,研制适用于肺癌的中医健康管理应用程序“肺i中医”和肺癌中医健康管理网络数据系统,给广大肺癌患者介绍中医药防治肺癌的理论知识,提供专业的肺癌证候辨识和体质识别,给予个体化的方药及针灸治疗方案,优选药膳和行为干预,康复锻炼的说明与指导等,并推出在线诊疗服
Mesocarp color is an important agronomic trait of Cucurbita maxima and is determined mainly by the contents and compositions of the carotenoids. The two inbred lines with significant differences in fruit flesh color were used in the study, the orange\'3
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.
Flower blight on anthurium (Anthurium andraeanum) was observed during August 2018 on an anthurium cultivation farm in the Songkhla Province of southern Thailand. The fungal isolate was identified as Neopestalotiopsis clavispora based on the morphology and
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
