无芒雀麦对土壤要求不严，耐贫瘠、严寒，耐碱性也较强，需氮较多，适宜与紫花苜蓿、沙打旺、野豌豆、百脉根、红三叶等豆科牧草混播，借助豆科牧草固氮作用，促进无芒雀麦良好生长[4]。本实验就是无芒雀麦单播草地和与紫花苜蓿混播草地对土壤理化性质的影响进行比较。

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

The influence of recessing in adh es ive layer with high elastic modulus on the peak stress of joint is not evident so that it would improve the actual strength of joint markedly based on the load bearing ability not being affected evidenly . On the other hand , the recessing in the joint with low elastic modulus adh es ive caus es the peak stress es increase evidently that may decrease the nominal and actual strength of the joint markedly .

对胶层和被粘物中应力分布的数值分析结果表明：胶层中的间隙对接头端部的应力分布无明显影响，但对间隙附近的应力峰值影响较大；随着胶粘剂弹性模量的增大，间隙附近的应力峰值有所降低；对于高弹性模量胶粘剂接头，胶层中的间隙对接头的应力峰值无明显影响，在不降低接头名义强度的同时可使得接头的实际强度显著提高；而对于低弹性模量胶粘剂接头，间隙使得接头上的应力峰值明显上升，可能导致接头的名义强度和实际强度显著降低。
