：坑探工程 词目：喷射距离 英文： 释文：喷射混凝土施工时，为保证最小的回弹率（量）和最高的强度，喷嘴与受喷面的最佳距离。原则上以能看清喷射情况，使料束集中，回弹量小为宜；也取决于喷头出口压力的大小，施工时应视其具体情况而定，一般以0.6～1.2米较好。
The tuyere of the new distributor was found having a twice longer jet distance as the former ones. Meanwhile, the new tuyere could also bring a better anti-deposition quality to the distributor.
实验结果表明，新型风帽喷射距离为参照风帽的两倍左右，该风帽在具有更大的吹扫面积的同时，喷射气速的变大更能保证大颗粒不在板上沉积，抗沉积能力得到加强。
