中文拼音 [cìxuándiào]
次懸吊
英文
secondary suspension-
After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "
眼幼蟲脫第三次即進入糠蝦期幼蟲期mysis stage ,此期之體形已略成蝦之狀態,且具特有之游泳姿態,即頭部及尾部均向下,成一直角彎曲而時作向後跳躍游動,又因成倒立狀態,懸浮於水中的中上層,又叫倒吊期,此期幼蟲對外界的環境因素,如水溫鹽分等變化,比前兩期來得更具適應力,主要餌料為豐年蝦brine shrimp的幼蟲,但其他大小略同的動物性浮游生物,如橈腳類copepoda輪蟲類rotifera均可。Secondly, calculation theory of construction for suspension bridge is presented under the ideal condition of dead load design. linetype change stiffness of cable and slip stiffness of supporting points are deduced based on segmental catenary theory. then numerical analysis method through sgkz2000 software are introduced in detail about calculating design linetype for suspension bridge, unstressed length of cable, erection linetype of cable and pre - displacement of saddle without loads, erection linetype of wire strands, the fixed position for erecting cable band and linetype of lifting stiffening girders
其次,根據懸索橋恆載設計理想狀態建立了懸索橋施工計算原理;以分段懸鏈線索理論為基礎,推導了懸索的線形變化剛度和懸索支點的滑移剛度;介紹了懸索橋成橋設計線形計算、吊索無應力長度計算、空纜線形與預偏量計算、絲股架設線形計算、索夾安裝位置計算和加勁梁吊裝線形計算的具體方法、數值演算法及軟體sgkz2000的計算模塊的實現。This paper also presents the methods of controlling unstressed length of cable, pre - displacement of saddle, anchor span tension, erection of wire strands, the fixed position for erecting cable band and cable length. determination and control approach of displacement of saddles during cable erection are also introduced. at the same time, the change course of linetype during construction period for suspension bridge is analyzed
再次,介紹了懸索橋的施工控制內容與方法,利用軟體sgkz2000對多座懸索橋進行了施工計算,提出本文關于懸索橋的主纜無應力長度控制、索鞍預偏量控制、錨跨張力控制、絲股架設控制、索夾安裝位置與吊索長度控制的方法;介紹了吊梁階段鞍座頂推量的確定與控制方法,分析了施工階段懸索橋的線形變化過程。On the base of fatigue loading spectrum achievements, combining the characteristics of large - span grid structure with hanging cranes and the using - requirement on fatigue loading spectrum of grid structure with hanging cranes, this paper has firstly put forward the theoretic method for constructing fatigue loading spectrum of grid structure with hanging cranes, organized the relevant program - - gjfls. and elementally established the program loading spectrum
在繼承疲勞載荷譜已有成果的基礎上,本文結合網架設置懸掛吊車的特點以及網架疲勞載荷譜的使用要求,首次提出了網架疲勞載荷譜編制的理論方法,並編制了相應的程序( gjfls ) ,初步建立了網架程序載荷譜。Disposable hanging devices for transfusion and infusion bottles - requirements and test methods
