Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

And There was no serious complication;②In the course ofinterventional therapy, Direct portal vein angiography demonstrated vena coronaria ventriculi(100%)andgastricveins(65.26%)andvenagastricaposterior38.43%, Angiography demonstrated venacoronariaventriculi communicate esophagus varicose veins, gastric veins and vena gastrica posterior communicategastric varicose veins. vena coronaria ventriculi had only a small percentage of double vein, about30.57%. The sites of vena coronaria ventriculi arising from the portal vein, splenic vein, portosplenic junction, were found in 52.06%、27.39%、20.55% respectively.③12 extrahepaticprotosystemic shunts were found in these patients. Include gastro-nephrosshuntof 3 cases, 7 caseswere splenetic- nephros shunt and 2 cases shown recanalization of umbilical vein .④The averageportal pressure before and after the procedure were 3.87±1.82kPa and 3.64±1.14kPa in 73patients, but to the time of rebleeding, it was 3.96±0.23kPa in the 11 cases.⑤There werethree kinds of variceal outcome: disappearance (54,low degree (19).⑥Spearman logisticanalyse and ANOVAtest shown liver function class, variceal degree of the splenic necrosis area,the blood direction in portal vein before operation and remain small collateral routes were thesignificant factors concerning outcome of varices.⑦The bleeding volume and portalhypertensive gastropathy are main risk factors of rebleeding.⑧The course of livercirrhosis is the risk factor of survival and extrahepatic portosystemic shunt , fine varices are thebeneficial factors to survival.⑨During all cases'followed-up data, the 1, 2, 3, 4, 5 yearcumulative survival rates and rebleeding rates were 17.81%, 28.77%, 38.36%, 43.84%, 47.95%and93.15%,91.78%,86.30%,83.56%,80.82%respectively. Conclusion The interventional disconnection treatment for liver cirrhosis and portalhypertension was designed suitability. It rapidlycontrol bleeding,butpressure of portal vein was notobvious high, perfusion was not low .it was compared with surgery therapeutic that interventionaldisconnection treatment was safe and had a significant clinical effect to hemorrhage and preventfrom rebleeding.

Through an analysis of the electromagnetic force on the electric heated rod, the authors work out the equation for calculating the electromagnetic force on unit area of the rod, and indicate that radial vibration of 100Hz will occur when the rod is in operation, which have little effect on the strength and sealing of the rod owing to minor amplitude.

电热杆的交流阻抗远大于导线的电阻，因此主要发热体为抽油杆，可快速有效地加热杆外的原油，而导线不会过热，有利于导线的绝缘与保护。通过对电热杆所受电磁力的分析，推导出了抽油杆内表面单位面积上所受电磁力的计算公式，从而得知电热杆工作时将产生沿径向向外的径向振动，振动频率为100Hz。但由于振幅较小，这种振动不会对抽油杆的强度和密封产生明显的不利影响。
