Columns The ECCS model code recommends that the design buckling resistance Nb, f i,t,Rd of a compression member at time t is given by Eq.

4.1。柱《 ECCS样板规范》建议用方程(2)时间&t&时压缩构件的&Nb， f i，t， Rd&之间的关系式确定材料预设计构件的压曲抗力。

With the niobium densities in SrTiO_3 increasing, the final potential and the discharge time of the SNH electrode first increased. When the density of Nb in SrTiO_3 thin films was 2%, the Potential was -0.9 V and the discharge time was 25 minutes.

随着掺杂浓度的提高，相应的SNH电极的光充电的最终电位及其放电时间都增加，当Nb的掺杂浓度为2％时，其值分别为-0.9V，235分钟。

The low values of Nb/U (7~8) suggest that the basalts probably experienced the addition of some subduction-related materials and/or a certain degree of crust contamination.

较低的Nb/U比值(7~8)暗示该玄武质岩浆在形成过程中遭受了一定程度的大陆地壳混染或与俯冲过程有关的物质的加入。

The results show that B2 phase presents broad fibred shape in the forged rod, and major textures are close to {112}〈111〉and {110}〈111〉; Fibred microstructure in hot-extruded tube becomes fine and fibres have broken, at the same time,{111} orientation of many grains is close to axis direction of tube; Microstructure in cold-rolled tube consists of B2,β-Nb and4Ni2O phases, fibres has heavily broken, which restrains phase transformation during cooling and heating.

结果表明：锻棒中的B2相呈较宽的纤维状，主要的织构组分接近{112}〈111〉和{110}〈111〉；热挤压管纤维组织变细且发生碎化，多数晶粒的{111}取向接近管材的轴向；冷轧管相组成为B2、β-Nb和4Ni2O，纤维组织发生严重碎化，抑制了马氏体相变的进行，{111}〈110〉和{112}〈110〉成为主要的织构组分。
