The hollow beam construction not only produce the stress concentration, reduce the effect of beam mass but also extended the bandwidth.
采用空心梁结构不仅能产生应力集中而且能减少梁的自身质量带来的影响，可以有效地展宽频带。
At this point conversion, beam bear a greater vertical force, the bottom of beam appears large tensile stress easily. The conversion layer slab with upper wall appears stress concentration easily.
此时转换主梁则在较小的传力区域内承受集度较大的竖向力，受力变得不利，梁底容易集中出现较大的拉应力。
The principle and an experiment device are introduced by which the measurement of the relative concentration of lotion is carried out continuously with the double beam system of laser.
采用双光路激光系统，对清洗液的相对浓度进行了连续测量，给出了测定原理和实验装置。
Through this method, various kinds of complicated loads on the beam can be expressed by one load concentration function.
用该方法，可将作用在梁上的各种载荷用一个载荷集度函数表示。
