紅外圖像將反映這一區(qū)別利用這一區(qū)別可以發(fā)現(xiàn)漏點，注意到由于地下排水，積水狀況可能因其它因素而不同。紅外輻射也可能由于非漏水因素產(chǎn)生，所以這種方法的應(yīng)用也受到限制。要點：漏水引發(fā)紅外輻射局部變化（溫度效應(yīng)）。4、相關(guān)檢漏法：從原理上說是一種基于聲振法的移植技術(shù)，屬于聲振法。漏水點引起的振動沿管道向兩側(cè)傳播，放在兩側(cè)不同距離的傳感器收到某時刻漏水點發(fā)出的聲波將有一個時間差，這個時間差是由管道聲速和漏點位置決定的。它的突出優(yōu)點在于利用管道傳聲好，直接在官道上測量并由儀器計算定點，排除人的經(jīng)驗因素，也可避免檢測者必須持工具到測點上方的問題，它的實際困難在于條件制約，必須有兩個放置傳感器的直接接觸管道點，也要對管道狀態(tài)十分清楚：包括走線、彎曲、管道口徑、聲音在不同管道中的傳播速度且傳聲條件要好。另一因素是價格昂貴，并對操作人員有一定的計算機(jī)應(yīng)用技術(shù)要求。目前已有多種國外型號相關(guān)檢測儀，在國內(nèi)市場銷售，國內(nèi)大自來水公司亦有不少應(yīng)用，但由于我國管網(wǎng)并無**檢測點，條件較差，應(yīng)用起來相當(dāng)不便，效果尚未理想，無法取代其它檢測手段***完成檢測任務(wù)。要點：相關(guān)檢漏法的技術(shù)先進(jìn)，但實際制約條件較多，價格昂貴。</p><div

會進(jìn)一步削弱振動的強(qiáng)度，聲音也逐漸減小。聲音除了描述大小的“聲強(qiáng)”外，還有“頻率”是指每秒振動的次數(shù)，單位是赫茲（Hz）（振動次數(shù)／秒），振動頻率越高，人耳感覺愈“尖銳”，但人耳可聽到的比較高頻率約16000Hz，再高就進(jìn)入“超聲”，振動頻率越低，人耳感覺愈“低沉”，但人耳可聽到的比較低頻率約16HZ，再低就進(jìn)入“次聲”。所謂“音質(zhì)”顧名思義，指聲音的品質(zhì)，它是一個比較難描述的概念，但基本上可以說是由不同頻率振動的合成情況決定的，單頻聲如鋼琴一次敲擊的聲音，而周圍環(huán)境各種發(fā)聲體，不同強(qiáng)弱，不同頻率疊加而形成環(huán)境噪聲，就是典型的多頻聲。至于“漏水聲”因其噴水口的振動，周圍被沖擊層的振動，水流的擾動，管壁的附加振動等的、發(fā)聲機(jī)理不一，而至人耳的復(fù)雜路徑不同，傳至地面再被傳感器、放大器經(jīng)耳機(jī)，而至人耳的復(fù)雜性，它也是一種異常雜亂的聲音。但是，不管它如何雜亂總還是有相當(dāng)?shù)囊?guī)律可尋。在同一點測聽，至少有下列三個特點：1.連續(xù)性：只要漏水不突然中止，發(fā)聲就不會中斷。2.穩(wěn)定性：只要供水過程不突然變化，如水壓急快升、降等，聲音的響度就不會突變。3.內(nèi)容有豐富性：不是單頻聲、音樂聲、白噪聲而是某種沖擊。</p></p><br
