The invention discloses establishment of a carrier based on a fish CRISPR/Cas9 system by using a gene knockout method ad an establishing method of the carrier, and relates to a carrier based on the fish CRISPR/Cas9 system and an establishing method of the carrier, so as to solve the problems that in a conventional transgenosis method the position that transgenosis is inserted into genome is hard to confirm and potential safety hazard can be generated when external DNA is led into cells and is randomly integrated by using a microscopic injection method, an electroporation method, a sperm carrier method and the like, and the problems that a conventional gene knockout method is complex in process, high in requirement on techniques, high in expense and long in experiment period, and the success rate is limited by multiple factors. By co-ejecting two non-integrated knockout carriers, namely, pX330-MSTN a and pX330-MSTN b, into zygotes of fishes in the 1-2 cell stages, high-efficiency and rapid gene knockout can be achieved.

The invention discloses an anti-falling television hanging frame. The anti-falling television hanging frame comprises a transverse fixed plate and a vertical fixed plate; the connecting places of the surface of the transverse fixed plate and the vertical fixed plate are fixedly connected through a fixed block; two sides of the transverse fixed plate and the vertical fixed plate are movably connected with extension rods through fixed bolts; matched fixed holes are formed in the surfaces of the extension rods; hanging hooks are arranged on the outer sides of the extension rods; placing grooves are formed in inner cavities of the hanging hooks; rubber pads are respectively arranged on two sides of the inner cavities of the placing grooves; and antiskid teeth are arranged on the outer sides of the inner cavities of the placing grooves. The anti-falling television hanging frame can achieve a fixing effect on televisions through the transverse fixed plate, the vertical fixed plate, the fixed bolts, the extension rods, the fixed holes and the hanging hooks, is better in fixing effect when fixing the televisions, prevents the falling condition of the televisions due to long-time use of the television hanging frame caused by incapability of fixing according to motors with different sizes by a traditional television hanging frame, and is suitable for popularization and application.

The invention discloses a jig frame intelligent layout method for ship sectional construction and computer storage medium. The jig frame intelligent layout method comprises the following steps that (1) body mass of a ship body curved surface sectional member based on a bounding box algorithm is acquired; (2) surface quality of the ship body sectional member on a projection plane is acquired basedon equal area; (3) point position layout of a jig frame is determined based on constraint conditions such as surface mass, the center of mass of a ship body sectional projection plane and the supporting weight of a single jig frame; (4) a mathematical fitting model of a ship sectional outer plate on the point position and height of the jig frame is acquired; (5) a contact point position between the jig frame and the sectional outer plate is determined; (6) a supporting point position of an uppermost pillar of the jig frame is determined; and (7) the rising height of a lead screw is determined.According to the jig frame intelligent layout method for the ship sectional construction, the accuracy and a utilization rate of the jig frame layout are effectively improved, an intelligent level ofthe jig frame layout is improved, the accuracy, the quality and the production efficiency of the ship body sectional member are improved, and the labor intensity of workers is reduced; and the jig frame intelligent layout method is first proposed in the field of ship construction at present, and has wide development space.
