Formal verification with HiLLS-specified models:A further step in multi-analysis modeling of complex systems

The multi-analysis modeling of a complex system is the act of building a family of models which allows to cover a large spectrum of analysis methods(such as simulation,formal methods,enactment,...)that can be performed to derive various properties of this system.The High-Level Language for Systems Specification(HiLLS)has recently been introduced as a graphical language for discrete event simulation,with potential for other types of analysis,like enactment for rapid system prototyping.HiLLS defines an automata language that also opens the way to formal verification.This paper provides the building blocks for such a feature.That way,a unique model can be used not only to perform both simulation and enactment experiments but also to allow the logical analysis of properties without running any experiment.Therefore,it saves from the effort of building three different analysis-specific models and the need to align them semantically.

一测多评法同时测定酸枣仁的多个成分含量

目的 :建立一测多评法测定酸枣仁中斯皮诺素、酸枣仁皂苷A、酸枣仁皂苷B、白桦脂酸含量的方法,并验证该方法在酸枣仁中应用的准确性和科学性。方法:以白桦脂酸为指标,采用超高效液相色谱法(UPLC)计算斯皮诺素、酸枣仁皂苷A、酸枣仁皂苷B与白桦脂酸的相对校正因子,进而用该校正因子计算其他3种成分含量;同时外标法测定酸枣仁中4种成分含量,比较"一测多评"法所得结果与外标法测得结果的相似度。结果:一测多评法和外标法测得的酸枣仁皂苷A、酸枣仁皂苷B、斯皮诺素含量的计算值和实测值之间的夹角余弦值分别为0.999 72,0.999 71和0.998 36,两者相似度较好,没有显著性差异。结论:UPLC可以简便、快速地测出酸枣仁4个成分含量,一测多评法适用于酸枣仁中4种有效成分的含量测定,相对校正因子可信。
