以浠水县清泉镇东门河村农村沼气池建设与使用情况为典型,研究我国农村沼气推广工作中遇到的问题,发现农村沼气推广工作尽管取得了很大的成绩,但经济效益、环保效益尚未充分发挥。经过调查分析,提出了参考性建议:农村沼气使用只有系统考虑、系统运作这一工程才会有明显的节能、减排效果;农村沼气规模化、产业化是比一家一户建沼气池更合适的投资与运作方式。 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献

The awareness of individualism can be traced back to the period of American Revolution when the Declaration of Independence was produced.It expressed basic beliefs concerning freedom,equality,democracy,privacy and the relationship between people and government,which were exactly what the philosophy of individualism mostly dealt with at that time.This paper is to exploit the essence of individualism by analyzing the Declaration .The analysis enables us to reconsider its significance to the issue of America human rights and foreign policies. 相似文献

Public speaking, as one kind of speech act, the speaker uses some pragmatic strategies, for example,the use of personal pronoun, in order to achieve effective communication. Speakers use the first personal pro-noun we and the second personal pronoun you conventionally, also there are some deviations in the use of person-al pronouns. However, theses kinds of uses have to be explained and understood in such a specific context. 相似文献
