A nonlinear finite element model is constructed, considering the large deformation, large strain, bolts pretension, bolt contact-slide, as well as material harden and soften, and Miese yield criterions and double nonlinear 3-D element are adopted, so it can predict performance of beam-to-column web connections under cyclic loads.

本文考虑大变形、大应变、螺栓预拉力及螺栓处的接触滑移、材料的强化和软化，采用Mises屈服准则、双重非线性空间单元，建立的非线性有限元模型能够比较精确地模拟梁柱腹板连接在循环荷载作用下的受力性能。

A different orientation would mean a change of earth gravity acting on flow boiling heat transfer. Based on analysis of the influence of buoyancy on flow boiling heat transfer at different orientation angle, the vertical upflow and downflow are used as ways of the arrangement of heating surface for the modeling test on earth's surface of the ...

在浮力对不同方向角下流动沸腾换热影响分析的基础上，提出了采用立式上升流和下降流来作为地面模拟微重力下流动沸腾试验的加热面布置形式，通过对这两种工况的比较研究可以典型地说明重力场对流动沸腾换热的影响。

Experiment results show that the proposed method can reconstruct ideally the 3D draping shape of fabrics.

实验结果表明，上述方法能够比较理想地实现织物悬垂三维形态的测量与重建。

A DRAT (Dimension Reduction and Absolute value Transformation) Method is proposed, which through the establishment of a minimum set of thelinear parameters in the spectrum model and its absolute value transformation, makes the 3M+1 dimension constrained optimizingprohlem into an equal 2M dimension unconstrained one.

谱峰分离的拟合方法涉及到比较复杂的高维和强非线性的数学规划问题。这使得一些流行的计算方法的收敛性强烈地依赖于初始参数值的质量l'I5l。

In this paper, on-line detection of random drift of angular displacement and velocity for gyro servo turntable has been developed by using inertial vibration displacement and velocty transducers.

1引言 目前，惯性导航技术已广泛地应用于航天、航空和潜艇导航中。在惯性导航系统中，对精密昂贵平台角位移和角速度漂移的实时在线测试要求比较高。

Though photos can be deceptive, to my eye this bird looks rather sleek, and is clearly not "dumpy" like the individual above, and more suggestive of Claudia's.

虽然照片可能会骗人，在我看起来这只相当壮健，而且明显地不像上面那只的短胖，比较建议是 Claudia's。

A new algorithm Eclat~+ was brought out, which is an improvement of Eclat and show good performance with a lot of datasets. We compare the two vertical formats, Tidset and Diffset.

本文系统地比较了Tidset垂直数据表示和Diffset垂直数据表示，对稀疏数据集，采用Tidset表示的数据库的规模远远小于Diffset表示。

I have discovered, as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build-up of stress, t hat abandoning the doctrine of "juggling your life", and making the alternative move into downshifting brings with it far greater rewards than financial success and social status.

或许正像凯尔西在不堪积劳重负而公开地辞去她在《她》杂志社的编辑一职之后一样，我已经发现，放弃那种"为生活忙碌"的人生信条并转而追求比较悠闲的生活带给你的回报远远大于经济成功和社会地位。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
