MYOELECTRICAL ROBOTIC SYSTEM FOR REHABILITATION PATIENTS WITH RESTRICTED MOVEMENT

This paper presents a robotic system for the rehabilitation of moving functions of the human body. It also shows that it is possible to apply the myoelectrical signal for correction of velocity of executive mechanisms movement. The myoelectrical signal contains information about muscle function and fatigue during the operation of the robotic system. The results of the simulation are described for. the robotic system which consists of two planar executive mechanisms. This robotic system is used for the training of the human hands.     

乌骨鸡日粮适宜苏氨酸水平的研究

采用单因素3水平试验设计研究了日粮苏氨酸水平对乌骨鸡各生长阶段生产性能的影响,结果表明:日粮中添加0.1%和0.15%苏氨酸乌骨鸡的体重、增重显著大于对照组和0.2%苏氨酸添加组(P<0.05)。     

飞机喷洒青虫菌六号液剂防治马尾松毛虫

飞机喷洒青虫菌6号液剂,大面积防治松毛虫的试验表明,常量喷雾用菌剂1125—1500克/公顷和低量喷雾1500—2250克/公顷,2—3天后防效可达90％以上,而且具有明显的后效。但防治区低量喷雾的防治效率比常量快.青虫菌剂对林间天敌昆虫、鸟类、蜜蜂等均安全。
