The presence of Falling Weight Deflectometer meets this need. 落錘式彎沉儀的出現(xiàn)適應(yīng)了這一需求。

The falling weight deflectometer (FWD) is used to evaluate the effectiveness of the impact compactor. 摘要將落錘式彎沉儀(FWD)成功地用于路基沖擊壓實效果的檢驗。

A method to backcalculate the layer moduli of pavements is proposed in the paper; the data are measured by the falling weight deflectometer(FWD)tests. 根據(jù)落錘式彎沉儀 (FWD)的彎沉盆動態(tài)數(shù)據(jù) ,在系統(tǒng)識別方法的原理基礎(chǔ)上提出了加速收斂的方法。

Moire deflectograms of the plumes were produced and captured with a home-made,wide-range,high-sensitivity Moire deflectometer. 使用自制的大口徑、高靈敏度莫爾偏折儀采集真實火箭噴焰的莫爾條紋圖;
