Kinetics of extracting mogroside from grosvenori momordica 罗汉果中苦参苷的提取动力学
Chen Dong-lian, Huang Run-jun, Ma Shao-mei, Huang Zeng-wei, L. An-pin, Yu Ai-qun
In order to obtain the extraction dynamics of mogroside from grosvenori momordica by ultrasonic wave strengthening, two dynamics model were used to evaluate this process and the extraction efficiency. The results show that the ultrasonic wave strengthening can improve the extraction efficiency of mogroside in the experimental conditions. The ultrasonic wave strengthening extraction dynamics equation agrees with the dynamic equation In C = γ In t + λ. Under the high frequency of ultrasound extraction or high temperature or long extraction time, the extraction process will not be controlled by the dynamic. In order to achieve the medicinal compositions with high activity and stability, the frequency, temperature and duration of ultrasonic extraction should be controlled in a certain range.
为了获得超声波强化提取罗汉果中苦参苷的动力学过程,采用两种动力学模型对超声强化提取罗汉果苷的工艺过程和提取效率进行了评价。结果表明,在实验条件下,超声波强化可以提高苦参苷的提取效率。超声波强化萃取动力学方程符合动力学方程In C = γ In t + λ。在超声提取频率高或提取温度高或提取时间长的情况下,提取过程不会受到动态控制。为获得活性高、稳定性好的药物组合物,应控制超声提取的频率、温度和时间在一定范围内。

The schedulability analysis and software design for networked control systems of vehicle based on CAN 基于CAN的汽车网络化控制系统的可调度性分析与软件设计
A. Cheng, Ling Zhang, T. Zheng
The worst-case response time of the message and busload are the main parameters in scheduleability analysis for the Controller Area Network (CAN) bus. This paper gives the probability distribution curves of stuffed bits in message's different length by introducing the probability model of stuffed bits. It obtains the maximum stuffed bits under a given probability P, to reduce pessimism of the worst-case response time and busload value. Taking it as a theoretical guide, and we design and develop scheduling analysis software on fixed priority message scheduling. Then we use the software to analysis the scheduleability for the messages in a Hybrid Electric Vehicle. Furthermore, a simulation experiment based on CANoe was made to test the design. By comparing the results, it shows that algorithm, as we introduced, based on the probability model of stuffed bits is right, and the designed software is accurate and reliable.
