In this study, soybean residues were treated with HCl and soybean residue cellulose was extracted, which was used to prepare cellulose nanofiber (CNF) using the high-pressure homogenization method. The maximum yield of CNF, the reaction temperature, reaction time, and HCl concentration were optimized. The optimum HCl concentration for acid treatment was 6%, the reaction time was 60 min, the reaction temperature was 80℃, and the maximum yield of soybean residue cellulose was 78.8%. The different CNF films were then prepared;the color, mechanical property, and light transmittance of the CNF films were studied. Compared to the properties of the CNF film prepared with the soybean residue cellulose by high-pressure homogenization 15 times (HGT-15 film), the mechanical properties of the CNF film with soybean residue cellulose by decolorizing treatment decreased, but the light transmittance increased. The film prepared by adding HGT- 15 CNF to whey protein was investigated for its mechanical property, light transmittance, and solubility. Unlike the pure whey protein film, addition of 2.0% CNF to the whey protein enhanced the mechanical property and water vapor transmission rate (WVT) of the film. With the increase in CNF content, the solubility of the whey protein film decreased, and then stabilized.

王珪的《泰定养生主论》是通俗易懂的养生专著,其中最引人注目的是对“痰”的论述和治疗。王珪认为,养生即治病,治病即治“痰”,治“痰”即养生,然必先正其心。中医的心,不单是心脏或大脑,而是所有细胞的意识集合。细胞是七情六欲发生的根源。从细胞器到系统,是独立性和整体性的统一,造就了痰的共性和个性。人体大多数物化反应是在液态环境中进行,至少也有液态成分的辅助,皆可生痰。生命不息,生痰不止,新陈代谢是痰的循环。不可控之痰,听之任之容之避之;可控之痰,先治其未生,痰生则以诸法应之。可控和不可控皆主于心,失衡为病,平和为养生。

《伤寒论》是张仲景在行医中对疾病治疗内容的记录和总结。清代医家柯琴钻研百家经典,结合自己在实践中的体会,提炼《伤寒论》之精华,指出其在流传过程中产生的偏差。同时,他建立了自己独特的认识和运用《伤寒论》的理论体系,并在实践中检验和修正。其强调,为医之道,识象、识证、识心、识源、识真等。更基于此,依据三阴三阳理论,创立了六经地面兵法学说,将人体分为相互独立又相互联系的六大系统,不同的系统基于各自的特点,于病程中有各自的表现和应对措施。邪正相争,如战阵征伐,故以兵法对客邪。其于病因病机,治法治则,皆化繁就简,契合仲景擒贼先擒王,直捣巢穴之旨。柯琴推崇六经类方,一切作为皆以六经变化为本。

作者： Zhang Xiangdong Shen peiyi li liangchao Wang Wei Bai Jianhua Zhang Wenbo Xidian University Xi＇ an 710071 China

In this paper, a novel method of licence plate recognition (LPR) using the vertical traverse density (VTD) and horizontal traverse density (HTD) is presented. The neutral network algorithm using VTD and HTD features is also an innovation. In addition, a so called secondary recognition method which splits characters into different parts is developed. Experimental results show that it is a simple and fast algorithm, which meets the request of real time and nicety performances of LPR and thus has applied value in intelligence transportation system (ITS).
