| 31. | Abstract: This paper discusses an adaptive control scheme on time varying parameter with pure delay and inertia.First,control system predicts parameter of the plant based on the parameters recognized,and then calculates control output according to minimum error control.By using this method,the system can maintain good performance when the parameters of the plant are varying.The steam generator system model is simulated,and a satisfied control effect is achieved. |

| 32. | The diffusion welding behavior of single-crystalline Cu to single-crystalline α-AIO with a Nb film interlayer and the joint microstructure properties were studied by TEM,SEM/EDS analyses and four-point bend testing.The Nb film interlayer deposited by electron beam evaporation on the ceramic side prior to diffusion welding was found to be olycrytalline and fiber-textured after diffusion bonding,with the close-packed plane(110)being parallel to the (0001)basal plane of α-AIO. |
| 、接头应力应变等各种行为，工艺参数多，虽然已经进行了大量的试验研究，但却对各种材料的连接机理尚未有明确的认识，为此人们试图借助于计算技术，对接头行为进行数值模拟，以便找到共同规律，对扩散连接过程及质量进行预测与实时控制 |
