As long as the root of the characteristic equation is within the unit circle of z-plane and the corresponding PID parameter is got, the closed loop control system is sure to be stable. Although the root of the characteristic equation can vary within the unit circle of z-plane,different value may affect the control property differently.

本文所采用的这种确定PID参数的方法，虽然可以使特征方程的根在z平面的单位圆内任意取值，但各种取值情况对变风量空调系统的控制品质的影响却不同，因此，要对各种特征方程的根的取值情况进行寻优，本文采用遗传算法对特征方程的根进行寻优，从而使控制器的参数得以优化。

Features and innovations in this study:(1) Longest successive time scale of Precambrian samples is studied;(2) The environmental and biological significances of the difference between . the carbon isotopic compositions of kerogen and coexisted carbonate were discoved;(3) The difference of biogeochemical processes between Proterozoic closed and open sea system was considered in the disccussion;(5) It is first time to carry out the chemolysis and thermolysis of kerogen in Precambrian organic matter research.(6) It is first time to apply molecular organic geochemical data to the reconstruction of Proterozoic Rodinia Supercontinent.

此项研究具有以下特色和创新之处：(1)研究对象连续时间跨度最长；(2)研究内容涉及面较全面；(3)较早详细探讨了前寒武纪沉积有机质的分子特征与古环境和生物群落的演化关系；(4)独立推导和论证了δ〓C〓和δ〓C〓的差值的生物和环境的重要意义；(5)在前寒武纪有机质研究中区分了局部封闭环境下的生物地球化学循环过程与广域海环境下的生物地球化学过程的差异；(6)开展了前寒武纪干酪根化学和热降解研究；(7)开创性地将分子有机地球化学的数据应用于元古宙Rodinia超大陆的重建中。

In the late 16th century, as the Renaissance era closed, an extremely manneristic style develops. In secular music, especially in the madrigal, there was a trend towards complexity and even extreme chromaticism(as exemplified in madrigals of Luzzaschi, Marenzio, and Gesualdo).

16世纪晚期，当文艺复兴时期结束后，一种极度精细的风格发展起来，在世俗音乐，尤其是牧歌的发展上，这种风格趋于复杂化甚至极度使用半音体系（比如在Luzzaschi， Marenzio，和 Gesualdo的牧歌创作中）。
