high_resolution_clock::replong long的同义词,它是 Microsoft 实现中用于表示high_resolution_clock::duration中时钟计时周期数的类型。 high_resolution_clock::time_pointtime_point<steady_clock>的同义词。 用于表示此时钟的time_point。 函数 名称描述
()获取当前时间点): system_clock:系统时钟,相对epoch(1970-01-01 00...:00:00UTC)的时间间隔; steady_clock:单调时钟,只能增长(后一次调用now()得到的时间总是比前一次的值大);一般是相对于系统启动时间的时间间隔; high_resolution_clock... } } 时间间隔duration chrono中使用duration模板类来表示...
high_resolution_clock::rep A synonym for long long, which is the type used in the Microsoft implementation to represent the number of clock ticks in a high_resolution_clock::duration. high_resolution_clock::time_point A synonym for time_point<steady_clock>. Used to represent a time_point ...
high_resolution_clock::rep Sinónimo de long long, que es el tipo usado en la implementación de Microsoft para representar el número de tic-tacs de reloj en high_resolution_clock::duration. high_resolution_clock::time_point Sinónimo de time_point<steady_clock>. Se usa para representar un ...
high_resolution_clock::now().time_since_epoch() 在 Windows 和 Linux 上返回显着不同的结果。在 Linux 上,它返回从 1.1.1970 到现在的持续时间。在 Windows 上,它返回 du...

high_resolution_clock在不同标准库实现之间实现不一致,而应该避免使用它。通常它只是std::chrono::steady_clock或std::chrono::system_clock的别名,但实际是哪个取决于库或配置。它是system_clock时不是单调的(即时间能后退)。例如对于 gcc 的 libstdc++ 它是system_clock,对于 MSVC 它是steady_clock,而对于 clan...

the precision of the module alignment in the x–y plane is limited by the imaging system. To image the modules a lens system with × 13 magnification is used in conjunction with an sCMOS camera. The imaging system has a spatial resolution of 0.5 μm which leads to an alignment ...
