Because each path takes the form of a chord ? a straight line connecting two points at the edge of the sun ' s disk ? astronomers could measure the angular shift between the paths by comparing the durations of the transits
因為每條路徑都是一條弦（連接太陽盤面邊緣兩點的直線） ，天文學家便能比較凌日持續的時間，而計算路徑間的角差。 -
According to the distribution of local impulse noise, an adaptive chord deviation method is used to avoid redundant detection or missing of impulse noise at the quick rising, descending or broken line area of data set
摘要針對現有脈沖噪聲濾波演算法在處理大斜率區域和斷線型激光掃描數據中存在的多判和漏判問題，提出了一種有效檢測脈沖噪聲的方法。 -
Abstract : in tokamak plasma radiation diagnostics, if the width of a detected plasma chord is comparable with the plasma minor radius, the plasma boundary may influence the line - integrated emissivity considerably and make it a weighted integral of the width - averaged emissivity
文摘:在托卡馬克輻射診斷中，當探測束線的極向寬度與等離子體小半徑可以比較時，等離子體邊界會顯著影響線積分輻射率，使其成為寬度平均輻射率的帶權重的線積分。 -
He used the higher notes of a chord as a melody line and made other changes
他運用更高音調的和弦音作為旋律線並做了其它的修改。 -
Secondly, the problem of the curve - surface mutual transforming and smooth - finishing have been analyzed farther. for the surface intersecting problem : owing to the introduction of the boundary points, as long as the intersecting points on a certain line, the full intersecting line can be gained. the intersecting line either intersects at the boundary of the triangle surface or forms the loop ; during the course of tracking, the selecting of the pace is restricted by the curvature, the number of the gained intersecting points are not in proportion as the chord - length ; the intersecting points not only record the coordinate and store the parameter
對兩曲面求交問題，當曲面細化足夠小時，曲面求交可近似看成曲面與平面相交問題，引進了邊界點的概念，因此只要知道交線上的任意點，就可以將跨越許多曲面片的整條交線計算出來，所求出的交線或者跨越曲面的邊界，或者形成交線環；從初始點出發跟蹤求解整條交線的過程中，步長的選擇採用了通過曲面片曲率來約束的方法，用該方法求出的交點在不同曲面片上的分佈數目不與弦長成正比；該求交方法包含了各曲面片的邊界線與交線的交點的求解，可獲得邊界交點的坐標值及其參數值。 -
Systemic measure scheme is designed on the basis of product line structure and every component of measuring system is specified. secondly, tube product shape imitating, rolling imitating of on - line tube product, measuring the chord length imitating with ccd and dimension measure arithmetic - circle least square estimation are finished. lastly, according to mentioned dimension measuring method, imitating operation and the result of imitating operation are emphatically analyzed
文章首先介紹了管狀產品的生產線結構，根據生產線結構設計了系統檢測方案，並詳細說明了檢測系統各部分的組成；其次對管狀產品形狀模擬、管狀產品在生產線上滾動模擬、線陣ccd檢測弦長模擬、尺寸檢測演算法? ?圓的最小二乘法進行了研究；最後重點對所提出的尺寸檢測方法進行模擬計算並對模擬計算結果進行分析。
