It was suggested that eric - pcr could substitute for rapd in research related to the genetic identification and genetic diversity in auricularia and other edible and medicinal fungi : 2 to a certain extent, genetic differences among auricularia strains tested in this study did not have necessary relativity with their geographical origins respectively ; 3 in this study, genetic diversity in a. polytricha was higher than that in a. auricula : 4 in this study, a. fuscosuccinea had a higher homology to a. auricula than to a. polytricha ; 5 morphological characteristics validated the results from eric - pcr and provided a potential explanation for the higher similarity coefficient between a. auricular and a. fuscosuccinea ; 6 southern hybridization was employed by choosing a strain from a. auricula as a probe which hybridized with a. auricula and a. fuscosuccinea except a. polytricha, further confirming the veracity of the results from eric - pcr ; 7 in this study, isozyme analysis could not cluster the 7 strains from three auricularia species to different groups efficiently ; 8 2 strains from two auricularia species revealed high conservative degree and the restriction fragment patterns by 4 kinds of restricted enzymes showed no diversity

改進的erica演算法加入時延因子,使在連接中具有不同時延的用戶在剩餘帶寬變化時,速率的調整具有不同反應,時延大的反應較遲鈍,時延小的反應較敏感。改進演算法使得小時延信源能更快的適應帶寬的變化,緩解了由於大時延信源速率調整的滯后而無法及時解除擁塞的現象。With the trend of emphasis on concealable attack and forcible ruin to military supporting systems, passive locating methods can be seen as an important direction to the development of locating methods and perfection to existing locating systems. passive locating methods have the merits of far distance, concealable receiving and low probability to be detected, compared to active locating methods. so, passive locating system can help to improve viability and battle effectiveness of the whole system in the electronic war environment
在越來越強調軍事支援系統隱蔽攻擊和硬殺傷的趨勢下,採用被動方式工作的無源定位方法作為定位方法發展的一個重要方向和對現有定位系統的完善,較有源定位方法具有作用距離遠、隱蔽接收、不易被對方發覺的優點,對于提高系統在電子戰環境下的生存能力和作戰能力具有重要作用,同時在航海、航空、宇航、偵察、測控、救援和地球物理學研究中有著廣闊的應用前景。Because of the limitation of the times, the advantage theory did not recognize the importance of tacitness of knowledge, the source of knowledge and accumulation effect of knowledge. it did not reflect the function that the enterprises possess to transfer the tacit knowledge efficiently and the impact of knowledge on fdi. the role of subsidiaries of creation of knowledge is neglected
但是由於時代的局限性,壟斷優勢論對知識的隱含本質、知識的來源和知識的累積效應缺乏足夠的認識,使得這個理論沒有反映出企業所擁有的並擅長的進行隱性知識轉移的功能,忽視了子公司在知識創造中的作用,沒有充分考慮到對外直接投資的知識效應,並且無法對中小企業海外投資進行有效的解釋。Two causes can be identified for this : the first cause is external, by which more and more appropriations of post - structuralism and post - modernism from the west have led cultural criticism to the pursuit of an impromptu pleasure, thus making cultural criticism into an intelligent game which is of great fun but not very practical ; the second cause is internal, by which intellectuals have changed their roles from " legislators " to " interpreters " since 1990 ' s, who, on one hand, could not take the responsibility of criticism, and on the other, changed the nature of cultural criticism by bringing a set of ideologies and ideas into it
形成這種局面的原因有二:越來越多地借用解構主義和后現代主義色彩的理論資源使得文化批評更注重追求一種即時反應的快感,文化批評變成了好看、好玩卻不解決實際問題甚至有可能遮蔽實際問題的智力游戲,這是其外部原因; 20世紀90年代以來,知識分子的角色發生了從「立法者」到「闡釋者」的轉型, 「闡釋者」一方面無力承擔批判的重任,一方面又把相關的一套觀念和理念帶入文化批評中而使其改變了顏色,這是其內部原因。Standard test method for nondestructive assay of plutonium in scrap and waste by passive neutron coincidence counting

在離子束介導外源全dna轉化中,外源全dna包含有供體的所有遺傳信息,這些外源片段對受體的影響是多方面的,因此轉化效果無法用統一的轉化率來衡量,這就給最佳轉化條件(主要是轉化劑量)的選擇帶來了很大的困難。Nuclear energy. fuel cycle technology. waste. determination of radioactive characteristics of solid waste packages by passive neutron counting
