現行民訴法實施十多年的司法實踐表明發動再審程序主體的多元性並沒有產生預期的效果,由於現行的民事再審主要是參照前蘇聯模式,在再審程序的啟動上,強調國家干預權,忽視當事人處分權;在事實認定上,追求客觀真實,忽視法律真實;在糾錯上,注重實體公正,忽視程序公正;從而導致在實際操作中出現了啟動再審的「主體無限、時間無限、次數無限、審級無限、理由或條件無限」的不良現象。Second chapter analysis the scientific misconduct reason. firstly, it lack science spirit. science spirit is basic moral norm that scientist set up and agreement norm for science study. because of many kinds reasons, the science spirit in the our country ca n ' t develop well, make the growth of science spirit in our country exist serious drawback, cause scholarship atmosphere not well. secondly, the scholarship judge rules have serious drawback. the manage way of quantity not used well for the scholarship management. the quality of the spirit product ca n ' t definition or measure by their quantity. the present scholarship of encourage system exist utility phenomenon, but impatient of scholarship management is the sources that produce large quantity plagiarize. the scholarship periodical uses the manuscript period over long, cause one manuscript give to some periodical. third reason is lacks of supervise, control and make track for the system of punish. the fourth is an administration management to act for the scholarship manages administration right dominate scholarship bushiness, cause official " look for rent " behavior
由於種種原因,科學共同體的科學精神在我國一直無法得到充分的發展,使得我國學術界的科學精神氣質的發育存在著嚴重的缺陷,由此導致了學風不正。其次是學術評價機制也存在嚴重的缺陷,量化管理方式並不適用於學術管理。學術研究者的精神產品的質量和績效是無法用數量來界定或衡量的,高校的評價機制同樣存在嚴重的缺陷,現在的學術鼓勵制度,存在著明顯的急功近利現象,而急於求成的學術管理正是產生大量學術剽竊、論文抄襲現象的根源之一。This thesis has introduced the development of the traditional wireless sensor network and current situation at first, then analyzed the principle an framework of the wireless sensor network, and the challenge to the traditional wireless sensor network technology for environmental monitoring, put forward the novel environmental monitoring system based on wireless sensor network technology, have recommended a kind of brand - new wireless node design plan of framework of wireless sensor network and node hardware to be designed and realized, then based on ieee 802. 15. 4 standard, this thesis analysed the design faces the wireless communication protocol stack used in environmental monitoring, have introduced the realize of physics layer, data chain layer, network layer, application layer. have solved the wireless sensor network data sampling, systematic energy - conservation optimize, this thesis summarized the preceding work finally, have looked forward to the development, application and commoditization in the future
