有二環紋的
英文
biannulate-
Firstly, this blade ' s length is compatible, secondly, it has the trace of the scabbard and the copper, thirdly, the it is possible it has the posy and complex veins, and lastly, the guangxi museum hasn ' t annulus dao, this dao is more compatible. peple may accept it more easily
留此刃一為長度尚可，二為有鞘痕跡及銅掛痕，三有銘文和錯紋的可能，四者廣西博物館尚無環首長刀，這把以為較合適，旱器人們還是較容易接受的啦。In this paper, the high - temperature low - cycle fatigue life and fatigue crack propagation life tests are carried on the cylindrical axial symmetry specimens having precrack or non - precrack with different types of notches of 16mnr steel in common use in the petrochemical industry contacting coke drum equipment, the stress / strain and the range of stress / strain of dangerous points are received through stress analysis of the specimens using finite element program under multi - axial stress state. at last, the equations of evaluating the high - temperature low - cycle fatigue life and the fatigue crack propagation life are found through using the least - square regression method
本文採用無預裂紋和帶預裂紋環狀缺口圓柱形試樣，進行了石化焦炭塔設備常用材料16mnr多維應力狀態下不同缺口形式的高溫低周疲勞總壽命試驗及裂紋擴展壽命試驗，並利用有限元程序對試樣缺口周圍及裂紋尖端附近進行了軸對稱多維應力狀態下的應力、應變場分析，來評價材料不同條件下的高溫低周疲勞總壽命和裂紋擴展壽命，最後利用最小二乘回歸方法，得到了該材料高溫低周疲勞總壽命和裂紋擴展壽命評價方程。Abstract : the time - variant reliability analysis of ship hull girders subjected to the deg r adations of fatigue and corrosion is quantitatively carried out in this paper. th e analytical formulations are derived and simple program is compiled. as a case s tudy, the time - variant reliability of a vlcc tank is calculated. it shows that th e degradation effects of fatigue and corrosion are very important for the load - c a pacity calculation of thsip hull girders. after the second special inspection ( 10 years ), the detailed inspection should be done in order to guarantee the safety of ship navigation
文摘:定量考慮船體構件疲勞裂紋擴展和環境腐蝕對船體梁承載能力的雙重衰減因素的影響，對船體梁的時變可靠性進行了分析，列出了時變可靠性分析公式並編制了相應的計算程序.以一艘大型油船的結構可靠性為例，表明疲勞裂紋和環境腐蝕在第二個特檢年（ 10a ）之後對船體梁承載能力有顯著的影響，此時開展詳細的船體結構檢查對保證船舶營運的安全性具有重要的意義These cause the system to wrap in the direction of the first, second, third, and fourth dimensions, sometimes referred to as the s, t, r, and q directions, for a given texture
這些值使系統在給定紋理的第一維、第二維、第三維和第四維的方向（有時稱為s 、 t 、 r和q方向）上環繞。In this paper, the part of apis based on minutia features includes mainly computing orientation, filtering, binarization, thinning, feature extraction, postprocessing and minutia matching ; the part of apis based on statistical features is composed of reference point location, extracting feature, classification and matching. some new approaches are brought forward : 1 ) in the preprocessing, a new binarization method of fingerprint images based on the orientation and the dynamic threshold is proposed, which has the excellent capability of noise resistance. this method makes fully use of the orientation and the characteristics of grayscale change, gets the binarized images from the primitive fingerprint images directly, instead of the series of processing such as smoothing, enhancement and binarization
本論文對這兩種系統做了深入地研究，從基於細節點特徵的系統中求取指紋方向圖? ?濾波? ?二值化? ?細化? ?特徵提取? ?后處理，到基於統計性特徵的系統中選取指紋圖像參考點? ?提取統計性特徵? ?分類? ?匹配等環節，都一一進行了討論，並提出了一些新方法： 1 ）在基於細節點特徵系統的預處理部分，本論文提出一種新的基於方向圖具有動態閾值的指紋圖像二值化方法，這種演算法能夠在保持特徵點不丟失的基礎上一次性完成一般指紋圖像處理中的無效塊分割、增強、濾波、二值化的過程。分享友人
