Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly. because the width dimension of loxodrome groove is narrow and the depth is deep, some machining methods are incapable, such as end - milling or electrochemistry. according to the peculiarities, a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched. because most firebox generatrix is composed of complex curves, it is very difficult to get cnc cutting program with manual means. in order to deal with the problem, the loxodrome mathematics model is studied, and an auto - programming software system is developed. the software system can generate cnc cutting program of loxodrome on many kinds of turned surface. the constriction - distension segment of firebox is the most representative workpiece. the sharp changing of its generatrix slope makes loxodrome milling difficult. with the theory analyzing and practice cutting experiment, some applied techniques, which include milling mode and direction, choosing cutter diameter and cutting start point setting, are developed. adopting the technology above, tens regular workpiece have been manufacturing. the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method. the developed technology is also worth to be referenced to other similar workpiece

    將液體火箭發動機燃燒室的冷卻通道設計為斜航線（等傾角螺旋線）槽形，可以大幅度改善燃燒室的冷卻性能.斜航線冷卻槽的槽寬尺寸較小而槽深尺寸較大，所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點，提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母線輪廓復雜，手工編制數控加工程序難度大.為了解決數控加工程序的編制問題，研究了斜航線的數學模型，開發了自動編程軟體系統.使用該系統，可以生成多種母線輪廓回轉體外表面上的斜航線數控加工程序.燃燒室收斂-擴張段的母線斜率變化大，加工難度大，是斜航線冷卻通道加工的最典型工件.經過理論分析和實際切削實驗，研究了針對該類型工件的片銑刀直徑選擇、銑削方式和方向、刀具調整和起刀點的設置等多項實際的加工方案.採用上述的一系列技術，已經成功地加工了數十個合格工件.經過兩年多的實際生產過程應用，驗證了所開發的斜航線冷卻通道加工方法的正確性和可行性.這些加工技術的研製成功，對其他相似類型零件的加工亦具有參考意義

Harold bloom, a monumental and legendary figure of literary criticism at yale university, a name that cannot be avoided in poetry criticism, is one of the strongest and definitely the most prolific critics of his generation or of several past generations. professor xu jing, correspondent of foreign literature studies, interviewed professor bloom in may 2006. this interview focuses on his theory of poetry that was explosively brought forth in the 1970s by his famous tetralogy : the anxiety of influence, a map of misreading, kabbalah and criticism, and poetry and repression. bloom regards his theory of " the anxiety of influence " as his most important contribution to literary criticism, and uses " dancing " to explain his famous yet baffling six rations of " misprision. " always preoccupied with his own theory, bloom here again traces the precursors of emily dickinson and makes a brief comparison between walt whitman and wallace stevens. looking back to his past, bloom gives a summation of his life ' s trajectory as a critic : a revivalist of romantic poetry, a theoretician of poetry, and a critic for the general public. bloom began his career as a critic of british romantic literature in the afterglow of the new criticism. in the 1970s, bloom brought forth his explosive " theory of poetry " in the tetralogy publised in very quick succession in the 1970s. since the 1980s, bloom has become less technical and hopes to reach a wider readership. his literary criticism and what he calls his " criticism of religion " for the general public have made harold bloom a household name in america as well as in the world. at present, the 76 - year - old harold bloom is intensely engaged in the writing of what he hopes to be his masterpiece, the anatomy of influence, which is to be published in 2008 by princeton university press

    哈羅德?布魯姆教授是耶魯大學具有里程碑意義和傳奇色彩的文學批評家，一個詩歌批評界的一個不可迴避的名字，是他那一代人或幾代人中最猛烈的、也無疑是最多產的批評家之一.本刊特約記者徐靜於2006年5月對布魯姆教授進行了采訪.本次訪談的重點是布魯姆在20世紀70年代以《影響的焦慮》 、 《誤讀的地圖》 、 《卡巴拉與批評》 、 《詩歌與壓抑》四部曲的形式相繼提出的、具有爆炸性的"詩歌理論" .布魯姆認為"影響的焦慮"是他對文學批評最重要的貢獻，並用舞蹈這一形象的比喻來解釋了他那著名的卻常常令人困惑的關于"誤讀"的"六個定量" .在訪談中，布魯姆還追溯了幾位對愛米莉?狄金森頗有影響的前輩詩人，並簡單比較了惠特曼和史蒂文斯.布魯姆將他的批評生涯概括為三個階段:浪漫主義詩歌的復興者，詩歌理論家以及面向大眾的批評者.在新批評的余輝中，布魯姆以對英國浪漫主義詩歌的批評開始了其批評生涯. 20世紀70年代布魯姆提出了他那爆炸性的、以四部曲的形式相繼問世的"詩歌理論" .進入80年代后，布魯姆的批評不再艱深難懂，他希望能擁有更廣大的讀者群.他為普通大眾所寫的文學批評及"宗教批評" （布魯姆語）使得哈羅德?布魯姆成為了美國以及全世界的一個家喻戶曉的名字.目前， 76歲的布魯姆正全力寫作《影響的解剖》一書，將於2008年由普林斯頓大學出版社出版
