Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

In order to study pathogenesis of primary changes in ventricular extrasystole ST-T and its clinical significance, 57 patients in conformity with diagnostic standard in primary changes of VPBs ST-T and their concerned parameters were carefully analysed.

Result Maximal tension P(subscript o of soleus tetanic contraction showed no difference between control and 1-week tail-suspension group. P33/P (P33, transient tension of tetanic contraction at the 33 s) was reduced significantly in SUS, and it manifested an increase in fatigability during tetanic contraction in SUS.

Applying integral intermediate value theorem, new effective elasticity modulus expressions were presented, which creep aging coefficient can be calculated by the creep coefficient of intermediate time of incremental time segment. Creep and shrinkage strain were treated as a kind of compulsive strain. Compulsive strain methods were used for the analysis of creep effect and shrinkage effect about concrete curved box-girder bridge.

Simulation results also show that saddle-shaped distributed AMF can more effectively inhibit constriction of vacuum arc.

对于小电流扩散态真空电弧，重点仿真分析不同电弧电流与不同纵向磁场对其关键特性的影响，部分仿真结果进行了实验验证；对离子处于超音速流动的收缩态真空电弧的仿真表明，真空电弧的磁收缩主要是由于霍尔效应引起的，离子温度和电子温度沿轴向先增大后减小，马鞍形分布的纵向磁场能够更有效地抑制真空电弧的收缩，而且阴极斑点分布对真空电弧特性也有着显著的影响；对离子处于亚音速流动状态的大电流真空电弧的仿真表明，部分等离子体不能到达阳极而损失，马鞍形分布的纵向磁场能够更有效地抑制电弧等离子体的损失，同时能使阳极电流密度和能流密度的分布更加均匀。
