If some noise is generated in the system, the coherence is less than unity since the total measured output includes not only the output power due to the measured input but also noise output due to the input noise and noise at the output side.

The cause of decrease from mix design compressive strength of 1100 kg/cm2 to actual compressive strength of 976 kg/cm2 was that fracture of cylinder started from the coarse aggregate, crushed stone ranging 19–25 mm in the result of observing the failure condition of cylinder tests.

The surface wave velocities were obtained from dispersion curves, which were plotted using Eqs. (2)–(4) based on cross power spectrum as shown in Fig. 5 as a typical dispersion curve.

如果一些噪音被在系統裡產生， 連貫性少于團結， 自從由於合標準的輸入，總合標準的生產不僅包括輸出功率， 但是由於在生產邊的輸入噪聲和噪音的也噪音產量。

減少從混合設計1100 千克/厘米2在2的976 千克/厘米的實際壓縮力量的壓縮力量那裡的原因， 汽缸的那裂縫從粗糙合計開始，碎石在觀察汽缸的破壞條件測試的結果方面範圍19 5毫米。

表面波速被從散佈曲線獲得，這被使用Eqs 繪製。 (2)4)基于十字架功率譜如圖中所示5 作為一條典型的散佈曲線。
