The stress condition ; overall stability ; effect of filling gravels into the hole of the block of the precast concrete interlocking blocks in the water flow during the flood period as well as the resistance parameters of the blocks are studied through experimental simulation ; in which a comprehensive analysis is made on the mechanical stability and the anti - erosion properties of the blocks , and then the requirement and the safety degree of the gravel filling are given 摘要通过试验模拟研究了预制混凝土连锁块在洪水期水流中的受力状况、整体稳定性、孔内填充碎石的作用及连锁块阻力参数，综合分析了连锁块结构的力学稳定性和抗冲性，给出了碎石填充的要求及安全度。
3 . the bamboo carbon tube inside absorb water the fiber , it can absorb the water of the flower pot bottom to the upper level mud , to provide the plant growth need . 4 . the bamboo in the flower pot carbon has the fluid matter , air of decontamination and protects fresh eliminate smelly , adsorb the moisture , improve the soil and shield the electromagnetic wave etc . effect 4 .种植篮内填充竹炭颗粒,竹炭具有自动调湿功能,含有植物生长所需的各种矿物质,还可净化水质空气保鲜消臭屏蔽电磁波辐射等功效,用竹炭颗粒水培花卉其实际效果较好。
3 . the parameters of steel frame with infill which affect the lateral , resistant ability , such as panel ratio , frame - to - panel connectors , frame - to - panel interface friction , gap between panel and frame and mortar joint bond and friction were discussed . it is emphasized that the reduced location , shape and dimension is very important for the function of dog - bone reduced beam flange and must be paid more attention 对填充墙高宽比、填充墙与钢框架抗剪连接件、内填充墙与框架梁空隙、填充墙开洞和钢框架与内填充墙界面摩擦等影响填充墙钢框架抗侧力性能的因素进行了讨论，并指出设计中考虑这些影响因素对于达到预期的设计目的是至关重要的，必须予以重视。
Using two - dimensional numerical simulation software , analyze the affect of isolated - trench ' s parameters on the breakdown voltages of three - class bipolar power devices ( whose ideal breakdown voltages correspond to 40v , 70v and 100v ) , which include width , depth , isolated material ' s dielectric constant , fixed interface - charge and field plate located at the top of deep - trench termination 利用二维数值模拟软件分析了影响三类典型应用的双极功率器件(对应的理想击穿电压bv _ ( cro )分别为： 40v ， 70v ， 100v )击穿电压的诸多因素(主要包括阱宽度、阱深度、阱内填充介质、界面固定电荷、阱区顶端场板) 。
Stress analysis on cross - section of traditional dumbbell cfst arch rib which concrete filled into the web space and new dumbbell cfst arch rib which concrete not filled into the web space during the concrete was filled into the inner space are introduced in this paper . analysis expressing the stress in the two connecting points of the web plates and the bottom steel tube of the traditional dumbbell is very large when concrete is filling into the web space , and easily causing some great cracks occurred in the weld sealing , which should causing the engineering field 对钢管混凝土哑铃形拱肋以及新型哑铃形钢管混凝土拱肋在浇注混凝土时的截面应力分布进行了分析，结果表明传统哑铃形截面(腹腔内填充混凝土)在灌注腹腔混凝土时，钢管与腹板交接处将产生很大的应力，容易引发爆管事故，应引起工程界的注意；新型哑铃形截面(腹腔内不填充混凝土而用工字钢加劲)灌注管内混凝土时，截面的受力情况较好，能避免爆管事故的发生，且能简化施工，降低拱肋的自重。
Total of 14 dumbbell cfst columns were tested under eccentric loading , those with 6 specimens which concrete filled into the web space and those with 8 specimens which concrete not filled into it . experimental results indicate that , the portrait strain on the middle section of two type specimens keep on the plane with each loading . the maximum load of columns which concrete not filled into the web space is lower than those filled into it 试验结果分析表明，两组试件的中截面纵向应变分布在不同的受荷阶段基本能保持平面；腹腔内不填充混凝土的哑铃形柱的极限承载力比腹腔内填充混凝土的哑铃形柱的极限承载力略小，但差值不大，且这种差值随着偏心率的增大而减小。
