摘要: A method for preparing a water-soluble curcumin mixture with high bioavailability includes the following steps: A) dissolving curcumin, vitamin C and ascorbyl palmitate in an ethanol aqueous solution, evaporating ethanol under reduced pressure, and vacuum drying to obtain a curcumin-vitamin C-ascorbyl palmitate co-crystal; B) high-speed emulsifying the curcumin-vitamin C-ascorbyl palmitate co-crystal and a wall material colloidal solution under vacuum, sequentially conducting a two-stage wet grinding, a homogenization and a potential adjustment to obtain an emulsified body; and C) subjecting the emulsified body to microencapsulation with a wall material twice and drying to obtain the water-soluble curcumin.

摘要: Use of micronized zinc compounds in wood preservation treatments containing micronized copper compounds significantly increases the efficacy of the treatment with respect to that of the copper compounds alone. Micronized copper compounds used at a retention in the range of from 0.005 to 1 pounds per cubic foot (pcf) expressed as CuO equivalent, and zinc compounds are used at a retention in the range of from 0.005 to 1 pcf expressed as ZnO equivalent, the increase in wood preservation efficacy over similar retentions of copper compounds alone can be seen in as little as 24 months.

摘要: A detecting device for assembly position of vehicle body side walls includes a first detecting device for location surface of front position and/or a second detecting device for location surface of reverse position. The first detecting device includes two first rules (22) and a front detecting sample (21), of which the top surface (27) is flat, and the lower surface (26) is a measuring surface. The two first rules (22) are arranged at the both ends of sides of the front detecting sample (21). The first rules (22) are perpendicular to the top surface (27) of the front detecting sample (21). The second detecting device includes two second rulers (32) and a reverse detecting sample (31), of which the top surface (37) is flat, and the lower (36) surface is a measuring surface. The two second rules (32) are arranged at the both ends of sides of the reverse detecting sample (31). The detecting device can detect and adjust the transverse deflection, longitudinal linearity and tortuosity of one of the location surfaces in the assembly positions better, thus avoiding the accumulating error in detecting in the prior art. A detecting method for assembly position of vehicle body side walls is provided.
