The present invention relates to a releasing mechanism, an aerosol generating device, a releasing method, and a smoking producing article. The releasing mechanism comprises: a rotary portion connected to the aerosol generating device rotatably between a first position and a second position, an aerosol-forming substrate and a heating body are relatively movable in a circumferential direction during switching from the first position to the second position; both in the first position and in the second position, the aerosol-forming substrate is in contact with the heating body. By using the releasing mechanism of the present invention, a user is allowed to easily pull out the aerosol-forming substrate from the heating body, and it is convenient to use and also facilitates cleaning of the aerosol generating device by a user.

The present invention provides a method of testing moisture retention of tobacco in which dynamic rules on moisture desorption of the cut tobacco in a dry environment are investigated by using a dynamic vapor sorption system and has found that a dry basis moisture content at an earlier stage of moisture desorption of the cut tobacco has a preferred linear correlation with a square root of time. A linear fitting for tis made by using values of a dry basis moisture content Mt at a time point t, and a rate constant k is obtained from a slop of the obtained straight line and used as a reference of testing the moisture retention of tobacco. The method can also be used to investigate the moisture retention of tobacco and filter humectants of cigarettes. In comparison with the conventional method, the method is convenient and applicable, and has a short testing period, a high degree of automation, preferred accuracy and preferred reproducibility, etc.
