1. A liquid outpouring method, comprising steps of:
outpouring, at a constant volume, a preset liquid at a first outpouring precision;
performing static weighing on the liquid outpoured at the constant volume, and determining an actual liquid outpouring amount;
calculating, according to the actual liquid outpouring amount and a target outpouring amount, a remaining liquid outpouring amount; and
outpouring, at a constant volume, the remaining liquid outpouring amount at a second outpouring precision, wherein the first outpouring precision is lower than the second outpouring precision, and an outpouring error of outpouring the liquid at the first outpouring precision is greater than an outpouring error of outpouring the liquid at the second outpouring precision.
