The first time the service is invoked, the entry point is obviously initialized with a start value. 首次调用服务时,入口点由一个start值显式地初始化。
To get the actual data bytes per second, you would have to take two samples ( to get a start value and an end value ), and divide the difference by the duration between the samples. 要获得实际的每秒数据字节,您将必须接受两个样本(来获取初始值和结束值),然后根据样本之间的持续时间来进行区分。
In future the start value varies with the version. 以后版本不同,可能值不同。
With the market compete turning worse, the cycle life of product shortening increasingly, natural resources of gradual dried up, people's environmental protection realize strengthening, relevant environmental protection lawmaking strengthen in all countries etc, the enterprise have to start value the reverse logistics. 而近些年来,由于市场竞争的加剧、产品生命周期的日益缩短、自然资源的日渐枯竭、人们环境保护意识的加强,以及各国有关环境保护立法的加强等,都迫使企业不得不开始重视逆向物流。
Second, you create a start time value by calling time. time (), and then call it again and subtract the initial value to determine how long the program takes to execute. 然后,通过调用time.time(),您创建了一个开始时间值,然后再次调用该函数,并且减去开始值以确定执行该程序花费了多长时间。
