Database of physical and chemical properties for solid wastes were constructed through investigation for single typical component and their mixture of solid wastes. The particulate trajectory model and heat transfer model were developed, based on the studies of Characteristics of solid wastes movement and heat mass transfer in rotary kiln. Pyrolysis experiments of solid wastes in lab and pilot scale rotary kiln pyrolyzers were performed. Mechanism of pyrolysis for typical solid wastes was analyzed. The characteristics of pyrolytic products, such as physical and chemical properties, composition and combustibility, etc, were investigated. A neural network model for the prediction of yields and properties of pyrolysis products was developed. Then, the potential applications of pyrolytic products and the substitution of pyrolytic fuels for corresponding commercial furls were investigated. The optimization of energy recovery and utilization for different wastes through pyrolysis was analyzed.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
