A mathematical model for gear shaping was presented for machining of externally meshed non - circular gears with shaping procedure in terms of the positional relationship between the tool ( cutter ) and gear ' s pitch curve
摘要根據范成法加工外嚙合非圓齒輪時刀具和齒輪節曲線間的位置關系，提出了插齒加工的數學模型。 -
Mandarin tone is characterized for tone level and tendency of pitch curve, so head - tail difference and relative tone level rate are determined as tone features for chinese tn - syllable word ; head - tail difference and tone level at the beginning of syllable are determined as tone features of syllable in continuous speech
漢語聲調主要由基音曲線的調位高低和走向決定。因此，本文選擇頭尾差和相對調位比作為三字詞音節的聲調特徵；選擇頭尾差和音節起點調位作為連續語音中音節的聲調特徵。 -
Taking no account of the non - uniformity of the detector, this paper analyzed the performance of the traditional four - quadrant angle - measurement algorithm and two other algorithms in calculating the pitch angle and the deflection angle of the incident ray, and also compared the error curve of the pitch angle calculated by each algorithm in the full plane
摘要在不考慮探測器非均勻性影響的情況下，本文分析了傳統四象限測角演算法和另外幾種演算法在計算入射光的俯仰角和偏轉角時的性能，還比較了在整個平面內各個演算法得到的俯仰角的誤差曲面。 -
According to the simulation result, the characteristics of tooth profile such as undercut and convexity of pitch curve of the machined gears could be analyzed and judged, so that a sort of intuitive judgment method was provided for designing and manufacturing of externally meshed noncircular gears with closed pitch curve
根據模擬圖形結果可以分析和判斷所加工的非圓齒輪的齒形特徵，從而為設計和製造節曲線封閉型外嚙合非圓齒輪提供了一種直觀的判斷方法。 -
These changes ( the result of the doppler effect ? familiar when a siren changes pitch as a fire engine passes by ) are much easier to detect than the wobbles themselves, and researchers can thus plot them out as a curve
這些變化是都普勒效應的結果? ?更習慣的說法是當一輛消防車經過時警報聲的變化，它們比恆星的位置移動更容易被探測到，而且研究人員能通過曲線圖的方式測定它們的具體位置。
