MRI findings usually fall into 2 categories: 1 A soft tissue mass that is hypointense on T1-weighted images and hyperintense on T2-weighted images with diffuse homogeneous or slightly heterogeneous enhancement within the collection; 2 As the phlegmonous mass necroses, there may be a peripherally-enhancing fluid collection.

MPR and VR were applied in the imaging post-processing. Results: All cases were divided into four groups according to the thoracic CT findings and pathologic results as follows:① spheral caseous pneumonia;② tuberculous granuloma;③ fibrous caseous nodule;④ Focal pulmonary consolidation with cavitation. The spheral lesion appeared inhomogeneous density (44/58). cavitation (14/58) or satellite foci (21/58). Contrast scanning was carried out in 31 cases, of which peripheral or ringshaped enhancement was seen in 15 cases, no enhancement in 9 cases and extensive enhancement was seen in 7 cases.

The results indicate that the formation of loess vertical joints can be divided into two phases:① the formation of inner fissure, i.e. in the beginning of deposition, the undulation of terrain leads to uneven distribution of loess, then when it rains uneven collapsibility generates, which leads to generate inner fissures ;② the stage of fissure extension, namely loess continues deposition after the inner fissures have been formed, the increasing of the top pressure makes the top of inner fissure lie in the state of tensile stress, so, when the stress reaches its tensile strength, the inner fissure extends along the vertical direction and then becomes a vertical joint.

结果表明黄土垂直节理的形成可分为 2 个阶段：①内裂隙形成阶段，开始沉积时，由于地形的起伏导致黄土厚度上的分布不均匀，在降雨时产生不均匀湿陷，从而导致产生内裂隙；②裂隙扩展阶段，内裂隙形成后黄土继续堆积，顶部压力的增长致使裂隙顶部土体受到拉应力作用，当达到其抗拉强度时裂隙就会沿竖直方向产生扩张而形成垂直节理。

Friction on the die/sample interface, as well as imhomoginiety of temperature distribution in the samples is studied to account for the deformation imhomogeniety, and the two factors lead to the barrelling and fold-over of the samples during compression.

其直接原因是样品和压头间的接触摩擦条件随温度升高和Z值的降低而恶化，并导致样品出现腰鼓和侧翻等不均匀变化现象。合金压缩时的温度分布不均也是导致出现不均匀变形的原因之一。

The density, electrical contact resistance and hardness of these two alloys were tested. The results show that Ag and rare earth oxide appear in Ag-Y and Ag-Ce alloy after internal oxidation. The distribution of oxide particles is inhomogeneous and seriously conglomerated in Ag-Y2O3 and Ag-CeO2 sintered bulk, but they are dispersed and uniform in Ag matrix after severe plastic deformation. The relative densities of wire materials are larger than 99% and the electrical contact resistances are low (＜2.2 μΩcm).

对某燃油泵活塞皮碗开裂的宏观、微观特征进行了观察与分析，并对皮碗的受力状态进行了分析计算，结果表明，皮碗的开裂性质为早期机械疲劳，其原因是皮碗在压制过程中，橡胶层与金属骨架间的结合力不均匀，结合力不均匀是由于JQ-1粘结剂界面氧化所致。
