The invention discloses a curing forming method and a forming die used for a non-slab composite material part. The method comprises the steps as follows: composite material part blank is arranged on arigid die body which has the same shape with the processing shape and gluing and layer-paving are carried out according to the required dimension; after the layer-paving is finished, the composite material part blank is arranged on the rigid die body; furthermore, surfaces with plane are provided with elastic soft layers; corner pure rubber layers which are connected with elastic soft layer jointseams are arranged at corner profile so as to form a soft die surface; subsequently, vacuum bag auxiliary material is arranged on the soft die surface so as to prepare the vacuum bag curing forming composite material part. By the flexible soft die consisting of rubber-fabrics, the method arranges the composite material part blank on the surface of the soft die after the layer-paving is finished;the method for preparing the vacuum bag curing forming part solves the surface quality problems in the prior art that the non-die surface of the bag-pressing forming composite material part is crapy,accidented and has no gloss and the like, and improves the working efficiency.

The invention discloses a method for detecting ship CFAR in SAR images based on bilateral truncation statistical characteristics. The steps include: 1. Obtain a SAR image, set a local sliding window composed of a target window and a background window, and calculate the pixels in the background window The logarithmic domain mean, logarithmic domain standard deviation and variation index of the logarithmic domain mean and logarithmic domain standard deviation and variation index are obtained, and the truncation rule is obtained to remove the heterogeneous pixels; 2. The logarithmic domain mean and logarithm Domain standard deviation estimation; 3. Use the lognormal distribution to model the gray probability density of real sea clutter; 4. Establish a decision rule based on a given detection false alarm rate, and target the pixels to be tested in the target window judge. The invention can effectively remove heterogeneous pixels in the background window, thereby effectively improving the detection rate of ship targets under complex sea conditions while maintaining a low false alarm rate, and has high calculation efficiency, and has good engineering application value.

A suction cup holder base for action cameras, comprising: a concave base (1), a suction cup (2) and at least two suction cup lifting members (3), wherein the suction cup (2) and the suction cup lifting members (3) are arranged at a lower surface and an upper surface of the concave base (1) respectively, and all suction cup lifting members (3) are uniformly distributed on the concave base, a center of the concave base (1) being centers thereof, and lifting rods (4) being provided having a one-to-one correspondence with the suction cup lifting members; the concave base (1) is provided with through holes (101) having a one-to-one correspondence with the lifting rods, the lifting rods (4) passing through corresponding through holes (101), wherein upper ends of the lifting rods (4) are connected to corresponding suction cup lifting members (3), and lower ends of the lifting rods (4) are connected to the suction cup (2); a connecting structure (5) for use in connecting a holder of an action camera is provided at the upper surface and a center position of the concave base (1). The suction cup holder base enables a greater vacuum degree at a lower mounting height and with a smaller mounting area such that the adhesive force of the suction cup is stronger and mounting on the holder base is more secure and stable; moreover, the connecting structure is located exactly at the center of the holder base such that the force of the suction cup is uniform and is not easily disengaged.

The invention provides an acetabular cup prosthesis, comprising: an inner cup body with a mouth; an adjusting outer cup sleeved on the outside of the inner cup body; a plurality of adjustment columns arranged along the circumference of the acetabular cup prosthesis A plurality of adjusting columns can be movably installed between the inner cup body and the adjusting outer cup, so that the adjusting outer cup can move between an initial retracted position and an expanded position. The technical solution of the present application can effectively solve the problem in the related art that the contact area between the acetabular cup prosthesis and the acetabular socket cannot be adjusted, which makes the fit between the acetabular socket and the acetabular cup prosthesis not good in some patients .

The invention also proposes a marketing interface setting device, electronic equipment and storage medium based on the WEB platform. The invention can improve the matching degree between the content contained in the marketing interface of the WEB platform and the user.

The invention discloses a cutting method of a female suit pants prototype. The cutting method sequentially comprises the following steps of: step 1, measuring the outside length, the waistline, the hipline, the crotch depth and the hip thickness of a human body; step 2, determining the total crotch width of the female suit pants prototype, wherein the total crotch width is equal to [(hip thickness * 0.44) + 6.34] cm; step 3, determining the front crotch width and the rear crotch width of the female suit pants prototype, wherein the front crotch width is equal to [(total crotch width * 1 / 3) + 0.5] cm, and the rear crotch width is equal to [(total crotch width * 2 / 3) - 0.5] cm; step 4, determining a cutting curve of a pair of female suit pants; and step 5, cutting and sewing according to the cutting curve, wherein 'cm' is adopted as a measure unit for length values of the outside length, the waistline, the hipline, the crotch depth and the hip thickness. According to the cutting method disclosed by the invention, a structure relation and a motion relation between the crotch width and the human body of the pair of female suit pants can be accurately presented, and the cutting efficiency of the pair of female suit pants can be effectively increased.

The invention belongs to the field of cutting machining methods for rubber rings and discloses a cutting machining method for rectangular rubber rings, which comprises the following steps of 1) machining a rectangular rubber barrel; 2) turning the rectangular rubber barrel, and turning the inner wall into the outer wall; 3) sleeving the turned rectangular rubber barrel on a round nylon lining; 4) clamping the nylon lining on a fixture of rectangular ring cutting equipment; 5) starting the cutting equipment to enable the nylon lining where the rectangular rubber barrel is sleeved to rotate in high speed; and 6) moving blades on the cutting equipment to cut the rectangular rubber barrel into a plurality of rectangular rubber rings. The cutting machining method turns the rectangular rubber barrel and sleeves the rectangular rubber barrel on the nylon lining to be cut and machined, thereby effectively removing four corners of the rectangular rubber barrel, resolving the problems that the nylon lining is untight in combining, cutting faces incline, and size fluctuation is large, and obviously improving machining accuracy of sizes of the rectangular rubber rings.
