MHD characteristics of interplanetary magnetic clouds has been studied for the simple case without large corotating stream interactions.The present discussions involve two strong clouds,the Dcember 19,1980,and March 19,1980 events moving in a high and a low speed solar wind streams respectively.The simple strong clouds are characterized by a main structure of low density and temperature but high magnetic field,the field vector of which rotates with a monotonically changing inclination 6 to the ecliptic plane.The main structure is proceeded by a turbulent high density and temperature structure,and followed by another less dense density enhancement.Large gradients of magnetic pressure Pm are observed at both the front and rear boundaries of the cloud.Inside the main structure of cloud,the Alfvenic speed Ca and ratios of the magnetic pressure to both the kinetic energy density and thermal pressure,μk and μp respectively are at least one order of magnitude higher than that in the background stream.Such a structure would help the MHD disturbances behind the cloud to propagate quickly across the cloud,and concntrate at the front boundary.It is suggestive that the magnetic gradient force due to expanding strong magnetic cloud as well as the dissipation of MHD waves in the high density structure could accelerate and heat the solar wind ahead of the cloud,build up the observed steep front in the speed profile and generate a forward shock.Also,there are indications that such expanding strong magnetic structure would be able to decelerate the solar wind from behind,and result in a double saw-teeth like speed profile similar to that observed in the outer,heliosphere.The structures of simple strong magnetic cloud could be compared with the structures observed successively in a typical coronal mass ejection event,i.e.a bright high density outer loop driven by a dark cavity with low density,presumably high magnetic field,inside which is an inner prominence core.In addition,the geomagnetic disturbances and cosmic ray decreases caused by the clouds" are briefly discussed in association with the Kp category of geomagnetic storms.

本文讨论了1980年12月19日和3月19日两次无大型共转流相联系的行星际简单强磁云事件的磁流体动力学结构特征。此两磁云均以高温、高密度的湍流结构为先导,接着是低温、低密度,磁场很强且倾角单调旋转的磁云本体,后随另一密度稍高的结构。磁云本体内Alfvén波速及磁压对动能密度和热压的比值异常地增高,有利于磁云后的扰动迅速穿越磁云向前传播并向前边界集结。磁云边界上的巨大磁压梯度力及MHD波动在高密度结构内的耗散有可能对磁云前的太阳风进行加速和加热,形成双锯齿流速图象。简单磁云的结构很象典型的日冕质量抛射事件。此外,还简要地分析了磁云引起的地磁暴和宇宙线下降。

Low cyclic fatigue testing of 45 steel with the circumferential V-notch indicatesthat the crack grows at a greater rate under variable-amplitude ascending overloading thanunder constant- amplitude overloading. Based on the experimental facts and the analysis ofthe fracture surfaces of the specimens,the mechanism of fatigue crack propagation under theoverloading is explored.It is proposed that at the moment of the application of the overload,the obvious instantaneous increase of crack growth rates is due to crack blunting.Then anadequate way of loading to make crack propagate quickly is found providing a basis for theengineering application of super- low cyclic fatigue fracturing.

通过对带有环状V型切口的45 ̄#钢圆棒料在恒幅过载和变幅过载下的低周次疲劳试验,表明变幅递增过载的裂纹扩展速率比恒幅过载裂纹扩展速率显著增大。基于试验事实和断口分析,探讨了过载下的疲劳裂纹扩展机制,说明过载时裂纹扩展速率瞬时显著增大是裂纹钝化的结果,进而寻找到了促使裂纹加速扩展的适宜加载方式,为超低周疲劳断裂的工程应用提供了依据。

In order to directly observe microscopic phenomena during static stressing, the institutensile test inthe SEM was carried out for SiC particle reinforced A356 aluminum alloy comlxisite. It was found thatcracks initiate from the porosity and propagate quickly. When some cracks were hindered by SiC particles,new branches generated. The fractured particles were also found and analyzed by using quantitative metal-lography. The result was compared with the section of common shape specimen in a tensile test...
