前言微波管的可靠性主要依赖于三个因素。首先,它受失效机理或制造过程中产生的缺陷的不利影响。可生产性差,制造工艺拙劣和工艺管理不善都会带来制造上的缺陷。其次,可靠性极大地取决于给管子提供的现场保护,例如闭锁,操作步骤和装卸。最后,为了可靠地工作,管子的标称工作点和设计的极限能力之问必须留有适当的安全系数。本文着重讨论实现微波管可靠工作的一个重要因素,即安全系数或降低定额(降额)。 Introduction The reliability of a microwave tube depends mainly on three factors. First, it is adversely affected by failure mechanisms or defects created in the manufacturing process. Poor manufacturability, poor manufacturing processes, and poor process management can all create manufacturing shortcomings. Second, reliability depends greatly on the field protection provided to the pipe, such as latching, handling and handling. Finally, in order to work reliably, the proper safety factor must be retained for the nominal operating point of the pipe and the ultimate design capability. This article focuses on an important factor in achieving reliable microwave tube work, namely, the safety factor or to reduce the quota (derating).
