精确长度 meaning in English

exact length

Although leases can be configured to extend the lifetime of a remote object longer than is precisely required , the reduction in network traffic devoted to reference counting and sending requests to clients , makes leasing an attractive solution when properly configured for a particular scenario
虽然可以将租约配置为延长远程对象的生存期以超过所需的精确长度，但是由于减少了专用于引用计数和向客户端发送请求操作的网络通信量，因而使租约在为特定方案正确配置时成为一种很有吸引力的解决方案。
