The invention provides a method for preparing camellia oil capsules at a low temperature. The method comprises the following steps: performing decoloring treatment on raw crude oil; generating electrolysis water by utilizing deodorization electrolysis equipment, namely performing electric decomposition on the treated water by virtue of an electrolytic cell to form acidic water and alkali ion water; adding the acidic water and discolored crude oil into a deodorization tank for stirring for 3.3 hours, performing oil and water separation, adding the separated oil and alkali ion water into a deodorization tank for stirring for an hour, performing oil and water separation again, and carrying out a degreasing process, thereby obtaining the finished camellia oil. Because the crude oil is subjected to low-temperature deodorization and foreign body removal treatment by utilizing the electrolysis water, hazardous substances brought by degradation of oil and carbohydrates, heat polymerization and denaturation of proteins which are easily caused in the production process due to high-temperature deodorization in the prior art can be completely avoided. In addition, the phenomena that the color of the camellia oil is darkened and the oil has scorched flavor and the like due to high temperature can be avoided.

The invention discloses an ultra-precise static-pressure main shaft dynamic characteristic online testing method capable of eliminating a measuring basis installation error and relates to the field of static-pressure main shaft dynamic characteristic testing. The method solves the problems that an existing method cannot achieve ultra-precise static-pressure main shaft dynamic characteristic online testing or a measurement result can be seriously influenced by the installation precision of a measuring reference plane according to the existing method. According to the ultra-precise static-pressure main shaft dynamic characteristic online testing method capable of eliminating the measuring basis installation error, a cone-shaped installation reference plane is machined at the rear end of a direct-driven ultra-precise static-pressure main shaft rotator, a standard ball is directly installed on the cone-shaped reference plane to serve as a measuring basis, two high-precision displacement sensors are adopted to measure the displacement change between the standard ball and the two high-precision displacement sensors when the main shaft rotates, the measured displacement change values are converted into a digital signal through a sensor signal amplification and data collection system and the digital signal is sent to a computer for data analysis and data processing, and then the ultra-precise direct-driven static-pressure main shaft dynamic characteristic online testing is achieved. Due to the fact that two channels are adopted to carry out measurement at the same time, detection of the axial deviation of the main shaft and detection of the radial deflection of the main shaft are achieved at the same time.
