Abstract: A multi-axis turntable includes a base, a rocker arm and a first driving device capable of driving the rocker arm to rock around the first rotation axis on the base. A swing arm and a second driving device, which is capable of driving the swing arm to swing around the second rotation axis on the rocker arm, are provided on the rocker arm. A workbench and a third driving device for driving the workbench to rotate around the third rotation axis are provided on the swing arm. The second rotation axis and the third rotation axis are parallel to each other or on different planes. Compared with the existing double rotating shaft turntable, the multi-axis turntable of the present invention has a cutting tool system of good and stable rigidity.

Abstract: The present disclosure provides tooth whitening oral care compositions comprising potassium peroxymonosulfate and a source of hydrogen peroxide having improved stability, and methods of using the same.

Abstract: Provided are a reinforcer (30) used for a plate heat exchanger (100) and a plate heat exchanger (100), the reinforcer (30) being used to reinforce an area around an opening (13) of at least one heat exchange plate (10). The plate heat exchanger (100) comprises multiple heat exchange plates (10); a heat exchange space formed between adjacent heat exchange plates (10) of the multiple heat exchange plates (10); a heat exchange channel (11) formed between the heat exchange plates (10), wherein the heat exchange channel (11) is used for a heat exchange medium to flow into or out of the plate heat exchanger (100), and is constituted by openings (13) in the multiple heat exchange plates (10); and a reinforcer (30), used to reinforce an area around an opening (13) in at least one heat exchange plate (10).
