In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors. In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system. We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production" It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.

Action research is adopted as the research method. Based on the difficulty faced while teaching music, this researcher feels that students in general lack the motivation to be creative. Eurhythmics, a favorite activity of students, is thus used as the main strategy to design teaching activities, with the aim to enhance the ability of improvisation. In addition, experimental teaching is adopted and the results presented by the researcher with a behavior observation record sheet and statistics, as well as audiovisual files of improvisation and musical diaries from the students. It is a combination of qualitative and quantitative research, whose results are presented as follows: 1. Designing the principle of a eurhythmics lesson: It starts from "listening" and applies elements of eurhythmics (force→space→time→relationship→locomotor →group formations) in teaching rhythm. It not only accumulates musical ability and experience, but also becomes the source of improvisation.
