Dyskinesia of the upper limbs caused by stroke,sports injury,or trafc accidents limits the ability to perform the activities of daily living.Besides the necessary medical treatment,correct and scientifc rehabilitation training for the injured joint is an important auxiliary means during the treatment of the efected upper limb.Conventional upperlimb rehabilitation robots have some disadvantages,such as a complex structure,poor compliance,high cost,and poor portability.In this study,a novel soft wearable upper limb rehabilitation robot(SWULRR)with reinforced soft pneumatic actuators(RSPAs)that can withstand high pressure and featuring excellent loading characteristics was developed.Driven by RSPAs,this portable SWULRR can perform rehabilitation training of the wrist and elbow joints.In this study,the kinematics of an SWULRR were analyzed,and the force and motion characteristics of RSPA were studied experimentally.The results provide a reference for the development and application of wearable upper limb rehabilitation robots.An experimental study on the rotation angle of the wrist and the pressure of the RSPA was conducted to test the efect of the rehabilitation training and verify the rationality of the theoretical model.The process of wrist rehabilitation training was tested and evaluated,indicating that SWULRR with RSPAs will enhance the fexibility,comfort,and safety of rehabilitation training.This work is expected to promote the development of wearable upper-limb rehabilitation robots based on modular reinforced soft pneumatic actuators.

[Objectives]Characters and microscopic characteristics of Aralia cordata were studied,to improve identification method for Aralia cordata.[Methods]Using pharmacognostic identification method,original plant morphology of Aralia cordata was observed,and microscopic observation of its root cross section and powder was conducted.[Results]It is perennial herb,with rhizome recess,arranged in clusters of nodules.There are double or triple pinnate compound leaves.It is glabrous or sparsely pubescent,with umbel.Flowers are white,while fruits are spherical and purple black.In microstructure,the cork layer on the cross section of root consists of 6-10 rows of cells,and there is secondary cortex.The parenchyma cells are rich in starch granules,and the cambium is not obvious.The vessels are uniserial,and the wood fiber is less,and the primary xylem is bipartite.There are many starch granules in powder,mostly single granules,round or quasi round,oval,umbilicus herringbone or short slit,with many marginal pits and reticulate ducts.Calcium oxalate cluster crystals are mostly gathered.Cork cells are yellowish brown and arranged neatly.The fibrous wall is thin,and the pore groove is obvious,and stone cells are occasionally seen.[Conclusions]Using character and microscopic identification method,it could accurately identify medicinal material of Aralia cordata,and provide reference basis for development and utilization of its resources.

锂电池在运输以及使用过程中的磕碰、外短路等原因造成的热失控极易诱发周边电池升温,导致热失控蔓延。为控制锂电池热失控传播,本文使用纳米纤维材料对热量传播进行抑制,以瓦楞纸、陶瓷纤维和玻璃纤维作为间隔材料展开锂电池热失控试验,从隔热性和耐火性两方面对隔热材料进行评估。结果表明:虽然纳米纤维材料的保温性能会促使首节电池更快进入热失控状态,但由于其良好的隔热性能,锂电池热失控的传播可以被有效抑制。对首节电池燃爆过程中隔热材料的热流密度进行测算,发现陶瓷纤维纸的热通量峰值更低,纳米纤维材料的隔热性能要优于瓦楞纸。同时对3种材料耐火性进行试验,判定电池燃爆时材料的可靠性,发现瓦楞纸极易燃烧,而纳米纤维材料具有良好的热稳定性。结果证明了纳米材料作为锂电池运输间隔材料的可行性。

本研究通过评价不同性别二态线索和吸引力的面孔图片来考察儒家文化下人们心中帝王面孔形象。采用FaceGen Modeller 3.1操作面孔性别二态线索,并通过PhotoShop CS5合成面孔材料。研究发现:被试认为女性化的男性面孔比男性化的男性面孔更具"帝王相";低吸引力的女性化男性面孔比高吸引力的女性化男性面孔更具"帝王相";不同性别被试之间的评价无显著差异。上述结果显示,在儒家文化影响下,人们偏好具有女性化面孔特点的帝王。
