Disclosed herein are \u03b1-Hydroxy sulfonate aldehydes and synthesis methods therefor. The display device includes: a pixel array unit and a driving unit which drives the pixel array unit. The first connector includes a first connector type, which may be a male J1962 connector type, and is configured of transmitting more of a plurality of signals there through. Imaged markers in the acquired image data of the marker assembly are located, and mapped markers are obtained by submitting spatial positions of the markers in the marker assembly of the phantom in the first pose to the registration mapping using the second pose as the imaging pose. In the fourth step of the method, the hybridized primer is or are elongated in a polymerase reaction. Compressed lair can be used to agitate and facilitate both cleaning and drying.
