A: A water-sensitive garment piece, a preparation process therefor, and a smart wearable monitoring garment. The water-sensitive garment piece is prepared using a water-sensitive shape memory polymer, and has a two-way shape memory function. The water-sensitive garment piece shrinks upon contact with water, causing the wearable monitoring garment to become tight, and therefore in a shrunken state when wet and a stretched state when dry. The water-sensitive garment piece thus converts between being tight and loose as the environmental humidity changes. The wearable monitoring garment prepared from the water-sensitive garment piece is used for body physiological signal collection, and prevents bodily discomfort caused by tight wearing for a long time. When a loose fit is required, a user enters a dry environment, and the wearable monitoring garment rapidly changes to a loose state, and when body physiological signal monitoring is required, the user need only spray a wet mist on the fabric or move to produce sweat, so that the fabric shrinks, and the wearable monitoring garment is tight and thereby collects body physiological signals. B: A down jacket provided with a detachable vest, which relates to the technical field of down jackets, comprising a jacket (1) and a vest (3), wherein the vest (3) is draped on a middle position of the outer side of the jacket (1), first sleeves (107) are sewn on left and right sides of the jacket (1), and the tail ends of the inner walls of the first sleeves (107) is attached to first adhesive patch rings (110); the tail ends of the outer walls of the first sleeves (107) are fixed to elastic bands (108), and the tail ends of the inner walls of the elastic bands (108) are fixed to protrusions (109); second sleeves (2) are detachably connected below the two first sleeves (107), and the the ends of the second sleeves (2) close to the first sleeves (107) are fixed to second adhesive patch rings (203); round groove blocks (202) are fixed above the outer side of the second sleeves (2), and the tail ends of the second sleeves (2) are provided with cuffs (201); and first velcro tape (102) is sewn on left and right sides of the upper part of the jacket (1), and a second velcro tape (103) is sewn below the outer surface of the jacket (1). The sleeves may be removed separately, which is convenient for separate cleaning, avoids the trouble of cleaning the entire piece, and improves the cleaning efficiency. C: Provided is a cutting processing method for a seam allowance of an overcoat. The method comprises the following steps: (1) cutting: flattening fabric in a yarn direction and then cutting same according to a structural board, and adjusting the magnitude of a slope; (2) drawing, and sticking a panel strip: laying the structural board on a front piece of the fabric, drawing a net line according to the structural board, and sticking, to the net line, a 6-degree bias or a 12-degree bias panel strip for fixation; (3) sewing: lifting the front piece and a facing to check that the shapes and sizes of the two pieces are complementary, and then sewing a seam allowance according to the position of the net line on the front piece; and (4) ironing. The method makes a breakthrough in the current conventional practices in terms of pattern-making. A seam allowance slopes according to the texture of the fabric, such that after being sewed together with the facing, the seam allowance can match the fabric slackness of a cut piece, wherein the slope is 0.5-2.5 degrees. During sewing, the 6-degree bias or the 12-degree bias panel strip is stuck for fixation, such that the seam allowance is slack after being sewed, and the completed seam allowance is both straight and beautiful.

The method comprises: when a first application operation interface is displayed in a first region of a screen, receiving a bending operation performed by a user with respect to a terminal; and in response to the bending operation, displaying a target mark in a second region of the screen, and displaying the first application operation interface in a third region of the screen, wherein the third region and the second region do not overlap, and the target mark is used to indicate at least one of an unread message, a second application, and a target function. D: An ambient light detection method, an ambient light detection apparatus, a terminal device, and a storage medium. The ambient light detection method comprises: (11) acquiring a detection signal of an ambient light sensor; (12) acquiring a brightness value of a screen region corresponding to the ambient light sensor; and (13) determining the intensity of ambient light on the basis of the detection signal of the ambient light sensor and the brightness value of the screen region corresponding to the ambient light sensor. When the intensity of ambient light is determined by means of the detection signal of the ambient light sensor, the intensity of interference light can be determined by means of the brightness value of the screen, and the impact of the interference light can be reduced, thus the intensity of ambient light is finally determined, such that the detected intensity of ambient light is more accurate.
