The invention relates to Chinese medicinal decoction used for treating lithiasis and a preparation method thereof, and relates to Chinese medicinal decoction for treating biliary calculus and renal calculus diseases. Main components of the decoction comprise ophiorrhiza pumila, dandelion, rhizoma sparganii, zedoary, white paeony root, herba pyrrosiae, bupleurum, Szechuan lovage rhizome, peach kernel, radix curcumae, gizzard lining, curcuma, knotgrass, gardenia, dried old orange peel, immature tangerine peel, liquorice and the like. The Chinese medicinal decoction can effectively heal intrahepatic bile duct calculus after the gall bladder is extirpated and calcification and sand-like calculus in the kidney, and simultaneously can effectively promote choleresis, improve the self-healing function of the gall bladder, and recover the functions of the gall bladder and the kidney.

The invention relates to a brake band (1) for a disc (2) of a ventilated disc brake, in particular capable of avoiding vibrations that cause annoying screams during the braking action, said brake band (1) extending between an inner diameter (D1) near the axis of rotation (X-X) of the brake band (1) and an outer diameter (D2) remote from said axis of rotation (X-X), said inner diameter (D1) being adjacent to the axis of rotation (X-X) of the brake band (1) and the outer diameter (D2) being adjacent to the axis of rotation (X-X) of the brake band (1). The axis of rotation defines an axial direction (X-X); the brake band (1) comprises two plates (3, 4) facing each other; the plates (3, 4) comprise inner surfaces (5, 6) which directly or indirectly face each other and delimit a gap (7); said plates (3, 4) being joined to each other by means of heat-dissipating and connecting elements (16, 17, 19), also referred to as connecting elements; connecting elements (16, 17, 19) which protrude from the plates towards the opposite plates and touch the opposite plates so as to form bridges connecting the plates (3, 4) to each other; wherein a first group of fins (18) of the connecting elements are each a fin (19), which is in a single piece and extends from near the inner diameter portion (D1) to near the outer diameter portion (D2); and wherein each of the fins (19) of the first set of fins (18) comprises a fin outer end portion (20) located near the outer diameter portion (D1); a fin outer end portion (20) of the fin (19) comprises a predetermined extension in the outer circumferential direction, namely an outer circumferential width portion (Lo); the fin (19) comprises a fin inner end portion (21) located near the inner diameter (D1); a fin inner end portion (21) of the fin (19) including a predetermined extension in the inner circumferential direction, namely an inner circumferential width portion (Li); wherein the outer circumferential width portion (Lo) is larger than the inner circumferential width portion (Li) in a cross-section taken along a cross-section plane including a radial direction (R-R) and a circumferential direction (C-C) and determined to pass through an average air flow point traveling through the gap; and wherein the fin outer end portion (20) of each of the fins (19) of the first set of fins (18) faces only on both sides in the circumferential direction (C-C) adjacent fins (19) of the first set of fins (18).

The invention discloses a split type high-order laser beam based tailor-welding method for automotive aluminum-silicon coated steel plates. The method comprises the following steps that 1, the two aluminum-silicon coated steel plates are fixed with a tailor-welding gap of 0.3-0.4 mm; and 2, in the protective gas atmosphere, split type high-order laser beam laser wire filling welding is adopted, a split type high-order laser beam is a high-order laguerre-gaussian transverse mode laser beam, and the order comprises TEM01, TEM02, TEM10, TEM20 and TEM30; a split type high-order laser beam spot comprises several high-energy areas and low-energy areas which are distributed in a staggered mode, a temperature gradient is formed during welding, metal flows from the high-energy areas to the low-energy areas in a high-speed staggered mode, a welding pool is stirred, and harmful elements are evenly distributed; and a welding wire contains N and Ni, and protective gas is argon, nitrogen and helium. According to the method, the split type high-order laser beam with special energy distribution is combined with the welding wire and a welding process, so that the distribution uniformity of aluminum elements in a welding seam is improved, and the welding quality is improved.

A process for improved yields of heavier olefins from a substantially narrow range of lighter hydrocarbon feed stock containing olefins in a reaction distillation column comprising feeding a narrow range of hydrocarbon feed stock containing olefin into a reaction distillation column at a point between its bottom and top, contacting the olefins at the point of feed with a disproportionation catalyst in alternating arrangement with an isomerization catalyst or a mixture thereof and keeping the reaction mixture in a state of vapor-liquid equilibrium for concentrating the lighter reaction products in the vapor phase and the heavier reaction products in the liquid phase by maintaining a controlled pressure and temperature profile in the reactive distillation column and for reactively creating the desired heavier molecular weight olefins over the catalysts and collecting it as bottoms product and removing the lighter molecular weight olefins overhead from the top of the reactive distillation column.

The invention discloses a new energy automobile ethyl alcohol storage device and a new energy automobile power system, and relates to the technical field of new energy automobiles, the new energy automobile ethyl alcohol storage device comprises a storage box, a feeding port is formed in the top of the storage box, and a conveying device is arranged on the front side wall face of the storage box; a U-shaped annular heat preservation groove is annularly formed in the side wall of the inner side of the storage box, and a constant temperature device capable of conducting appropriate temperature control on water in the heat preservation groove is arranged in the middle of the bottom of the heat preservation groove. An ethanol solution in the storage box vibrates in the storage box, when the ethanol solution sinks, the corresponding position on a deformation limiting plate deforms, meanwhile, folding auxiliary balls in folding auxiliary grooves in the deformation limiting plate are limited and influenced by gravity, and the deformation limiting plate is forcibly driven to conduct sectional type attaching deformation; and therefore, the situation that the ethanol shakes when the automobile bumps is reduced.
