La0.7Sr0.15Ca0.15Co1-yFeyO3-δ(LSCCF)powders with 0.2y0.5 for the applications as the cathode materials in intermediate temperature solid oxide fuel cell(ITSOFC) were synthesized by glycine-nitrates-process(GNP) using metal-nitrates and glycine as the raw materials.
Therefore, the LSCF has become the recent focus of ITSOFC cathode materials research since it can reduce the operation temperature of SOFC using LSCF as cathode materials [1-5].
For researched the performances and synthesis method of cathode materials deeply, La0.7Sr0.15Ca0.15Co1-yFeyO3- cathode materials were prepared by glycine-nitrates-process (GNP), and the influences of B site doped on performances were researched in this paper.

Robust speed control algorithm of welding wire feed system based on the state space model Xiumei Wu1,a, Limin Sha1, Taozi Si1, Lei Jiang2,b 1.School of Computer Science, Shanghai Second Polytechnic University, Shanghai, China 2.School of Information Science and Technology, Donghua University Shanghai, China axmwu88@163.com,bwang-sunduan@sohu.com Keywords: Robust control; Welding wire feed system; Random disturbance Abstract.In the modern welding technology of metal materials, the welding robot is a very important factor.
Introduction To the manufacture of the advanced materials, the welding is often a kind of important method.
Many high-performance materials’ manufacture needs the process of the welding, such as tungsten rhenium alloy. [1] In the modern welding technology of metal materials, the welding robot is a very important factor.
To some kinds of high-performance materials, the feed speed of welding wire must change with the requirement and the disturbed feed speed will seriously affect the quality of the welding.

Introduction From the mechanical perspective, engineering material which consists of many different componential phases is inhomogeneous material.
So, the more differences of the equivalent stress at the interface of Si particles and Al matrix, the more drop and fracture in the use of the materials.
