The present invention discloses a coaxiality detection method. The coaxiality detection method is characterized in that a standard workpiece corrects an axis of a rotating shaft, so that a pointer of a measurement instrument points to a zero; after the rotating shaft is corrected, the position coordinate of a probe is used as a detection reference point, and the position of the probe is fixed and constant; an end hole of a to-be-detected workpiece sleeves on the rotating shaft, the inner wall of the other end of the to-be-detected workpiece is contacted with the probe of which the position is fixed and constant via an adjusting device, and the pointer of the measurement instrument is observed whether to point to the zero; if the pointer points to the zero, the situation that the two end holes of the to-be-detected workpiece are coaxial is indicated; if the pointer deviates the zero, the situation that the two end holes of the to-be-detected workpiece exist a coaxiality error is indicated. During the measurement process, if the pointer of the measurement instrument points to the zero, the two end holes of the to-be-detected workpiece are coaxial, and the whole detection step is simple and is easy to operate. The measurement instrument probe is contacted with the inner wall of the other end hole of the to-be-detected workpiece directly, so that the pointing accuracy of the pointer of the measurement instrument is guaranteed, the whole detection method is high in accuracy, and an accumulated error is small.

Provided is a system event logging system for recoding a log of system events which relate to a process being monitored, the logging system having the aim of selectively recording system events that are necessary for purposes such as the reproduction of operations and excluding system events that are outside the intended purpose. Flag conditions and flag operation instructions are provided for each of the filters in a filter list (702), and the system event logging system uses the flag conditions as the conditions for applying the filters. When applying the filters, the logging system operates the flags according to the flag operation instructions. Thus, interrelated operation between the filters can be achieved by means of the flags, and also, interrelated operation can be achieved by means of the flags even between the processes performed for the system events.

The invention discloses a container and a liquid variation detection method and device thereof. The method comprises the following steps; detecting whether the state of the container is changed or not; If it is detected that the state is changed, obtaining first data related to the liquid; Obtaining initial data related to the liquid, wherein the initial data are data related to the liquid and measured last time; And calculating and recording the current liquid variation according to the first data and the initial data. The liquid drinking amount of a user each time is recorded by detecting the change amount of the liquid in the container.
