The applicability of this constitutive model is evaluated with the simulations of material tests conducted by Sasaki et al., includes (1)Uniaxially constant strain amplitude cyclic test,(2)Fast in tension/Slow in compression constant strain amplitude cyclic test,(3)Slow-fast-slow constant strain amplitude cyclic test,(4)Cyclic strain with tensile hold time test. Simulations based on this constitutive model have a good agreement with (1),(2) and (3), proofs that it can describe the cyclic stress-strain behavior of 60Sn/40Pb solder very well.

为验证本模式之能力，本文选择Sasaki等人之实验为对象，分别对60Sn/40Pb焊锡在(1)定应变振幅之循环单轴负荷实验、(2)拉伸快/压缩慢之定应变振幅循环负荷实验、(3)慢-快-慢之定应变振幅循环负荷实验、(4)拉伸应力保持之循环应变实验下的材料行为进行模拟，由(1)、(2)及(3)之结果证明本模式对60Sn/40Pb焊锡循环应力-应变整体行为具有理想的描述能力，并对循环塑性应变范围与应力范围之值有准确的预估。

By Ensemble-averaged Method, the mean field was got to show the 3D structure of flow. By Phase-locked Averaged Technique, the periodic mean field was got to reflect the periodic unsteady characteristic. The 3D structure and the periodic unsteady characteristic of the unsteady flow within the vaneless and vaned diffuser were discussed through analyzing the mean field and the periodic mean field.

离心风机扩压器内非定常流动的实验研究本文完成了离心风机两种结构条件下无叶扩压器、有叶扩压器内部的非定常流动瞬态全流场的实验测量，获得了不同运行工况下PIV的瞬态流谱，为研究扩压器内部非定常流动提供了基础实验资料。

In the vaneless diffuser, which was little bigger than that of vaneless diffuser. The reason was the intervention of vane enhanced the unsteady degree of the flow and expanded the unsteady effect region.

叶轮对有叶扩压器内部非定常流动的影响也没有维持到有叶扩压器的出口，非定常影响区域为大约在半径r/r〓=1.3以内的区域范围，略大于无叶扩压器内的非定常影响区域。

Ding porcelain Tumbler with big,middle and small different standards,have many modes and different ornament,is delicately made by White Clay of Ding kiln one time agglomeration in high temperature,don't include any harmful materials.it's ornament is made by archaizing carve with lines in relief and chisels in intaglio that shows traditional auspicious lines ornament which is very welcome like "Dragon Flying up and down in cloud","Phoenix ringing vigorously","riches and honour,glory" and so on.it is deserved to fame of products of safeness to human being and environment because it is helpful to health with long-term use because of it's arista in the ostium which have subtle massage effect when touchs man's mouth,so it's very popular in the market.
