The present invention provides a tamsulosin hydrochloride sustained-release capsule. The tamsulosin hydrochloride sustained-release capsule of the present invention can avoid the sudden release of the drug tablets and the performance differences generated from the gastric emptying differences, display minor food effect or do not display food effect, and obtain the stable curve of the plasma drug concentration and longer action time simultaneously, so as to reduce the occurrence of cardiovascular side effects, greatly improve the safety, effectiveness and compliance of the medication for the patients. The tamsulosin hydrochloride sustained-release capsule of the present invention can ensure the sustained and regular release of the main ingredient tamsulosin hydrochloride after the oral administration, and the present invention is characterized by convenient administration, durable function, stable efficacy, fewer side effects and so on.

The invention discloses a hollow-out unit body suitable for the metal 3D printing technology. The hollow-out unit body comprises a main structure and an extension structure. The main structure comprises a dodecahedron structure formed by main rib strips serving as the edges. The extension structure comprises extension rib strips extending outwards from the directions of the body diagonals of a dodecahedron. The included angle between each main rib strip and the projection plane is theta, and theta is larger than or equal to 30 degrees but smaller than or equal to 90 degrees. The invention further discloses a metal part comprising the hollow-out unit body. The hollow-out unit body is of a self-supporting structure and suitable for metal 3D printing forming process conditions. Weight reduction of the unit body structure exceeds 90% maximally. A hollow-out weight reduction structure formed by the unit bodies through size changing, direction changing, density changing and other array modes is good in isotropy and high in weight reduction ratio, and the reliability of the part is improved.

The invention discloses a method for manufacturing a high-strength, toughness and layered tear-resistant steel plate with a thickness of 50-80 mm. The continuous casting slab with the same composition as the steel plate is heated to 1210-1250° C., and the heating time is controlled at 1.1-1.2 min / mm. The casting slab temperature is ≥1150°C, the starting rolling temperature in the recrystallization zone is ≥1050°C, rolling 6-7 passes, the intermediate slab is waiting for temperature, the starting rolling temperature in the non-recrystallization zone is controlled at 800-830°C, and the final rolling temperature is controlled at 800~830℃, rolling 8~9 passes, after rolling, the steel plate is cooled by laminar flow in the strong cooling zone and the intermediate cooling zone at the cooling rate of 6.5~13℃ / S and 2.0~6.0℃ / S respectively, ACC system The roll speed is 0.6~0.8m / s, and the grain size of the steel plate produced is 10.5~12 grades; the comprehensive properties of the steel plate are: yield strength ≥ 420MPa, ‑40°C longitudinal impact energy ≥ 200J, Z-direction performance sectional reduction rate ≥ 65%. The present invention obtains high-strength steel plates by precisely controlling rolling, and then reasonably opens the water groups in the strong cooling zone and the intermediate cooling zone to control the cooling rate, effectively refine the grain and structure of the steel, and reduce core defects.
