-LOS_TickCountGet()：获取当前的系统节拍数。通过调用OsGetCurrSchedTimeCycle()函数获取当前调度时间周期，并将其除以每个节拍的周期数，得到节拍数。
-
-LOS_CyclePerTickGet()：获取每个节拍的周期数。通过将系统时钟频率除以每秒节拍数，得到每个节拍的周期数。
-
-LOS_MS2Tick()：将毫秒转换为节拍数。将给定的毫秒数乘以每秒节拍数，再除以每秒毫秒数，得到节拍数。
-
-LOS_Tick2MS()：将节拍数转换为毫秒。将给定的节拍数乘以每秒毫秒数，再除以每秒节拍数，得到毫秒数。
-
-OsNS2Tick()：将纳秒转换为节拍数。首先计算每个节拍的纳秒数，然后将给定的纳秒数加上每个节拍的纳秒数减1，再除以每个节拍的纳秒数，得到节拍数。如果节拍数超过最大值，则将其设置为最大值。
