The invention discloses a taro cutting machine, which comprises a support and at least one slicing device which is arranged on the support, and the taro cutting machine is characterized in that the slicing device comprises a cutter group and a pressing block, wherein the cutter group comprises a plurality of cutters, and the cutters are transversely arranged in parallel and distributed on at least two horizontal planes; and the pressing block enables a taro to sequentially pass through the cutters of the cutter group on each horizontal plane to be sliced, the pressing block is connected with a driving device, and the pressing block is provided with a cutter groove corresponding to the cutter group. In the slicing process, the cutters are staggered on different horizontal planes, so that the taro has sufficient staggering space in the slicing process. The taro can be prevented from being squeezed into segments, and the slicing quality is improved.

The invention belongs to the field of microscopic tissue slice, particularly relates to a method for quickly slicing and dyeing fish tissues. The method comprises the following steps: 1) solidifying the fish tissues for 4-6 hours by using stationary liquid, cutting the solidified fish tissues into slice tissue blocks being 2mm long, 2mm wide and 1-2mm high, soaking the slice tissue blocks for 10-20 seconds in egg white which is diluted by using distilled water at the volume ratio of 1:1, freezing the slices, and pasting slices, and 2) placing for 3-5 minutes at room temperature after being pasted, dyeing, airing, and sealing by using neutral gum and cover glass for observing with microscope. Through the method, the time is shortened and the problems of freezing slice tissues, cell dissolution and blurry image under microscope are solved.

The invention provides a method for cutting a transparent material by using ultra-short pulse laser. The ultra-short pulse laser output by an ultra-short pulse laser generating device is condensed by a condensation device so as to form a bunching laser beam; the bunching laser beam enters from the surface of the transparent material to be machined, so that the center refractive index at a laser application point is increased to form a waveguide structure along a laser emitting direction; the laser is transmitted to the inside of the transparent material along the waveguide structure, and continuously generates a waveguide structure along the laser emitting direction in a transmission process until the entire waveguide structure and the laser penetrate through the transparent material; and therefore, the laser moves in a direction which is vertical to the surface of the transparent material at uniform speed, so that a waveguide plane is formed in the transparent material. The invention further provides a device for cutting the transparent material by using the ultra-short pulse laser. The method and the device for cutting the transparent material by using the ultra-short pulse laser provided by the invention have the advantages of fast cutting speed, small cutting seam, no material consumption and no powder pollution. When the machined material bears a suitable external force, the material is cracked only along a stress fault surface; the broken surface nearly has no conical degree; and the roughness is good.
