three beam meaning in English
三射束
Examples
- If the three beams are on track , then the two subsidiary photodetectors have equal amounts of light and will be quite bright because they are only tracking on land
如果三束激光处于轨道的正确位置，因为两个副光束只射到轨道中间的“台”上，因而两个附加探测器上将得到等量的光。 - The precast and pretressed continuous beam is differente from the monolithic prestressed continuous beam in capability . so there shoule be difference in performance on load . because of little research in this field , i designed and tested three beams which is two - span continuous beams
由于装配式预应力混凝土连续梁与通常的整浇式预应力混凝土连续梁的性能有较大的区别，其受力性能也应有所不同，但目前在国内外对此类结构形式还缺乏较为系统的研究。 - When whole analysis is carried through the beam - lattice method and bridge surface is made of box beams with one box and two cells , according to the principle of constant bending rigidity and every part revolving the same neutral axis , a box beam can be simplified into three beams in the places of corresponding webs . thus effective transfer of shearing force can be ensured , and global property can be reached through that of three beams , this kind of method is simple and is able to ensure engineering precision ; secondly , the paper is based on elastic theory , adopts finite element method and carries through the first kind stability analysis towards zhongshan no . one bridge
在选用梁格法进行整体分析时，遇到桥面系是单箱双室的箱型梁时，按照抗弯刚度不变且各部分绕着同一中性轴的原则，将一个箱型梁在相应的腹板处简化成3根梁，能够保证剪力的有效传递，而且可以由这划分的3根梁的性能得到箱型梁结构的总性能，这种方法简便易行且能保证工程精度；其次，本文基于弹性理论，采用有限元法对中山一桥进行了第一类稳定分析。 - This paper presents a manufacture and calculating method for castellated beams . according to the method , three beams are designed and tested , the detailed and trustworthy experimental data are obtained . in comparison of the castellated beam with the circular hole castellated beams during the process , that the yield of load and the strength limit for the latter are higher than the former is verified
本文通过设计制造两种不同截面形式的3根蜂窝梁( 2根圆孔、 1根六边形孔) ，进行了两点集中荷载下的试验，取得了较为翔实可靠的试验数据，通过整理与分析，对两种蜂窝梁的整体受力性能和承载力作出评价，得出圆孔蜂窝梁的屈服荷载和极限承载力都高于六边形孔蜂窝梁的结论。 - This dissertation focuses on the systemic experiments and theoretical analysis on strengthening reinforced concrete beams with high - performance ferrocement . the main research content and achievements can be summed up in the following aspects : 1 . experimental study on flexural strengthening of beams with ferrocement : based on the tests of sixty - three beams , the performance of beams flexural strengthening with ferrocement has been tested
本文对采用这种新材料加固的钢筋混凝土梁进行了系统的试验研究和理论分析,研究的主要内容和成果如下: 1 .复合砂浆钢筋(丝)网加固混凝土梁抗弯试验研究:在63根梁的试验基础上,研究了复合砂浆钢筋(丝)网加固对混凝土梁抗弯性能的影响和作用。
