- Beam propagation factor(BPF) was introduced as the beam quality factor for the combined beam. 引入光束傳輸因子(BPF)作為合成光束的光束質量評價因子,計算了單元光束質量、大氣傳輸、跟蹤抖動、相位控制等因素對合成光束質量的影響。
- Inclined combined beam model with roof bolted are presented and solved,the expressions of support parameters of bolt are derived. 建立大傾角煤層回採巷道錨桿支護的傾斜組合梁模型,並進行解算,給出錨桿支護參數的表達式。
- Forward support bolt combined with roop rock by bolting can play a roll of combined beam,which can prevent roof rock caving immediately after explosion. 超前支護錨桿錨固后與頂板岩石構成一體,這樣使超前錨桿形成組合梁作用,放炮后,能夠阻止頂板岩石冒落。
- This paper described the practice of using combined beam theory and suspensory theory,such as roof bolt,net,steel rope,and shotcrete being used together to strenthen roof control. 應用組合梁和懸吊理論,對鬆軟岩層採用支護新技術,即錨、網、帶、索、噴等聯合支護方式,加強對鬆軟岩層巷道頂板的控制,降低了材料支護費用,提高了軟岩巷道支護的可靠性,同時也提高了鬆軟岩巷的掘進速度。
- The far-field intensities and divergence angles of combined beam of two copper vapor lasers with UR90 resonators coupled at small magnification (M=1.21) were measured and analyzed experimentally. 並利用銅蒸氣激光器實現了兩台低放大倍率(M=1.;21)UR90腔的相干並束輸出,對輸出光束的遠場方向性進行了測量分析。
