Triterpene acids（TAs） are the major bioactive constituents in the medicinal fungus Ganoderma ***, fermentative production of TAs has not been optimized for commercial use, and whether the TAs isolated from submerged culture G. lingzhi mycelia possess antitumor activity needs to be further proven. In this study, enhanced TA yield and productivity were attained with G. lingzhi using response surface methodology. The interactions of three variables were studied, i.e., initial pH, dissolved oxygen（DO） and fermentation temperature,using the Box-Benhnken design. The optimum conditions were an initial pH of 5.9, 20.0 % DO and 28.6°C. These conditions resulted in a TA yield of 308.1 mg/L in a 5-L stirred bioreactor. Furthermore, the optimized conditions were then successfully scaled up to a production scale of 200 L, and maximum TA production and productivity of295.3 mg/L and 49.2 mg/L per day were achieved, which represented 80.9% and 111.5% increases compared with the non-optimized conditions, respectively. Additionally, the triterpene acid extract（TAE） from G. lingzhi mycelia was first found to be cytotoxic to the SMMC-7721 and SW620 cell lines in vitro, and the TAE exhibited dose-dependent antitumor activity against the solid tumor sarcoma 180 in vivo. Chemical analysis revealed that the key active triterpene compounds, ganoderic acid T and ganoderic acid Me, dominantly existed in the extract.

多电飞机功率电传作动系统,采用电能取代飞机能源系统中的液压能、气压能等二次能源。典型的功率电传作动系统主要有电静液作动器(EHA)和电机械作动器(EMA)两种。根据飞机系统运行特点,以EHA为研究对象,对其工作原理与结构特点进行分析,建立了EHA系统中驱动电机、液压泵、作动筒、活塞杆负载等的Simulink线性化仿真模型。同时,针对驱动电机控制精度低的问题,由于传统PID控制的EHA存在舵面控制精度差和频域带宽过窄等问题,故采用了滑模变机构控制对传统PID控制进行改善优化,并进行对比仿真。仿真结果表明,滑模变结构控制的EHA系统的控制质量得到了明显提高。
