specimen rack (b,校服燃燒速率測定儀生產, fig. 2). the specimen rack provides supports for the
frames in which the specimens are mounted. the angle of inclination is 45°. two
guide pins projecting downward from the cct of the base of the rack travel
in slots provided in the floor of the chamber so that adjustment can be made
for the thickness of the specimen in relation to the flame front. a stop is
provided in the base of the chamber to assist in adjusting the ition of the
rack.
2 樣本架b,供應校服燃燒速率測定儀,圖2。樣品架為安裝樣品的框架提供支撐。傾角為45°。從機架底座中心向下-的兩個導銷在燃燒室地板上的槽中移動,校服燃燒速率測定儀銷售,以便調整試樣相對于火焰的厚度。腔室底部設有止動塊,以幫助調整齒條的位置。

control knobs (not shown). there are two of these knobs which hold the
rack in test ition. the knobs can be reached under the stage of the cabinet
and permit forward&backward movements of the rack when loosened.
5 控制旋鈕未顯示。這些旋鈕中有兩個用于將機架固定在測試位置。旋鈕可以在機柜的臺下夠到,松開時允許機架向前和向后移動。
