The present work was aimed at optimization of medium components, which have been found to play a very important role in enhancing the sporulation of fungus (Larroche 1996; Ooijkas et al. 1999), with the aid of RSM. In the preliminary step of optimization, six carbon sources, five inorganic nitrogen sources and six organic nitrogen sources were evaluated to determine optimal carbon and nitrogen source. T hen, a Plackett–Burman design was used to identify which components of the media had significant effects on spore production. Subsequently, a central composite design was employed to optimize the factors, which had significant influence on spore production. The results were analyzed by response surface analysis. 第94页，共153页，编辑于2022年，星期六 二、正文的写法 根据文章内容的需要采用各种不同的写作方式展开论述。 可以是论证某一命题、观点、假设， 或描述某一实验方法、过程、结果， 或说明某事物的特点、功能、规律等。 第95页，共153页，编辑于2022年，星期六 类型一：从实验得出结论，并加以讨论。 往往是根据目的，设计并做实验，对方法、材料、过程、结果加以描述和讨论，论证是否达到目的。 类型二：对已有模型或公式，验证它们的正确性。 第96页，共153页，编辑于2022年，星期六 （1）定义和描述 描述一些物体的外观、结构、原理、过程。 定义的写法按结构可分为一般定义、特指定义和扩展定义。 第97页，共153页，编辑于2022年，星期六 一般定义（general defination):一则完整的定义包括术语（term)、动词、类别（class)差别（distinguishing characteristics) 第98页，共153页，编辑于2022年，星期六 方式1：被下定义的事物（name)+动词+类别（class,n.)+特征（characteristics) Nutrition is the science that deals with the effects of food on the body, or the way the body uses food for optimal health.
