In order to detect the bottom thickness, cavity, leak and deformation of steel meshes in secondary lining of concrete in tunnel construction, the authors evaluate the wave character and the detected result in the second lining of the tunnel using surveying radar technology and conclude the wave character in the tunnel lining which has mass defect and tested the accuracy and reliability of this technique
摘要為檢明隧道混凝土二次襯砌中的底界厚度、空洞、漏水、鋼筋網變形等質量問題，利用探地雷達技術，通過對檢測方法及工程檢測實驗的研究，進行隧道二次襯砌中雷達波形特徵參數及檢測結果評價，總結了隧道襯砌質量問題的雷達波形特徵，驗證檢測方法的精度和可靠性。 -
Hope that one cavity warm blood of us is able to get the general public from the bottom of self ' s heart, the customer, government functional departments, the news media understanding draw especially holding out
衷心希望我們的一腔熱血能夠得到社會各界，特別是客戶、政府職能部門、新聞媒體的理解和支持。 -
The soil color changed from dark brown to grey brown, at the bottom layer 4 pillar cavity structures were uncovered. the pillar - cavity structure close to the north wall had signs of cement covering and the areas nearby there were signs of scratch marks from excavators
土色由深褐轉灰褐色，底層出現四個柱洞結構，近北墻的一個柱洞周圍甚至有以水泥鋪底的現象，附近並且有四爪怪手抓痕。 -
Results indicate that the characteristics of cavity flowfield were altered similarly by gas and liquid injection. the local boundary layer or shear layer are modified by injection on upstream / bottom wall of cavity, and the cavity shear layer immediately becomes angled with respect to the main flow direction. the injection on fore wall of cavity has little effect on the characteristics of cavity flowfield
結果表明:氣體/液體噴流對凹腔整體流動特徵的影響是一致的，凹腔上游/底壁噴流破壞了當地附面層或剪切層，導致凹腔剪切層偏向主流方向;凹腔前壁噴注對凹腔流場特徵基本無影響。 -
Adding injection on bottom or fore wall of cavity, based on chief injections on upstream, provides worse lean flameholding performance. experiments on the drag of cavity flame holder were conducted by force measurement system
利用直連式試驗臺推力測量系統，對凹腔火焰穩定器的阻力特性進行了試驗研究，主要對不同噴注方式、不同當量比時的熱試阻力特性進行了對比和分析。
