查询词典 under load

Steel moment-resisting frames with welded beam-to-column connection were traditionally regarded as having excellent performance, and widely adopted in steel constructions, but this opinion changed after the 1994 Northrige earthquake and the 1995 Hyogoken-Nanbu earthquake. These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure. So it can reduce the damage, and is one of the best choices for resisting earthquake.

中文题名钢框架梁柱端板连接在循环荷载作用下的破坏机理及抗震设计对策副题名外文题名 Collapse mechanism and design criterion of steel beam-to-column end-plate connections under cyclic load 论文作者郭兵导师顾强学科专业结构工程研究领域\研究方向学位级别博士学位授予单位西安建筑科技大学学位授予日期2002 论文页码总数127页关键词钢结构框架结构抗震设计钢框架梁柱端板连接馆藏号BSLW /2003 /TU392 /6 传统观点认为，梁柱焊接刚性连接具有较好的抗震性能，因此在工程中得到了广泛地应用，但1994年的Northrige地震和1995年的阪神地震改变了这种传统观点，这两次地震也引起了工程技术人员对端板连接的再审视。

The experiment acquired pressure distribution and circulating rate under three fluidizing velocity (3.5m/s、4.5m/s、5.5m/s) and different media load. An experimental equation was acquired between circulating rate and the distribution of the pressure. And the relation between the circulating rate and the opening rate of the valve connecting the returner and the EHE was carefully discussed as well as the relation between the pressure of the EHE and the flow rate of the fluidizing air.

If the Deathless dwell not in the heart of death, If glad wisdom bloom not bursting the sheath of sorrow, If sin do not die of its own revealment, If pride break not under its load of decorations, Then whence comes the hope that drives these men from their homes like stars rushing to their death in the morning light?

如果永生不住在死亡的心里，如果愉快的智慧不是冲破悲伤的外壳而绽放出花朵，如果罪孽不是死于自我暴露，如果骄傲没有被虚荣的重负压垮，那么，驱策这些人离开家园，如同繁星在晨光中奔向死亡的希望，来自何方？

This peak arises from the preferential rotation of the axes of carbon pairs existed in the specimen under the influence of an alternating load.

在外加应力的作用下，这类碳原子对轴的择尤旋转便引起了内耗。根据这个机构并结合内耗测量过程中试样内部碳原子重新分布的情况，可以推导出碳浓度和内耗峰高度之间的定量关系，并从而求出合金的点阵空位形成能和构成碳原子对时所放出的能量。
