Problems solved by technology

Commonly used transparent agents for transparent treatment are potassium hydroxide or sodium hydroxide. Potassium hydroxide and sodium hydroxide have good transparent effects, but they are highly corrosive. When the concentration exceeds 3.5% or the transparent time is too long, the bones of the specimen are likely to be brittle and cracked. due color and integrity, resulting in production failure

Abstract

The invention relates to a method for making a transparent parusvenustulus skeleton specimen. Compared with the prior art, the dehydration gradient is increased, the gradient difference is reduced, dehydration is soft in intensity and thorough, and deformation or denaturation of the specimen can be prevented in the dehydration process. According to the method, sodium hydroxide and xylene are combined for degreasing, the degreasing effect is better and more thorough, degreasing time is short, specimen making time is shortened to a certain degree, and making efficiency is improved; a method that two kinds of transparency agents including potassium hydroxide and glycerin are used in cooperation is adopted, transparency is carried out for two days through a low-concentration potassium hydroxide solution and is soft, the specimen is not damaged, then the specimen is transferred into glycerin potassium hydroxide transparency liquid, and transparent treatment is carried out for 5 days; due to glycerin, corrosion of the specimen by potassium hydroxide is reduced, the concentration of the potassium hydroxide can be increased to be higher than 3.5%, and the transparency effect can be improved; as alcian blue dye liquor is used, cartilage is dyed into a blue color, and the transparent skeleton specimen is bright in color and more attractive.

Description

technical field [0001] The invention relates to the technical field of specimen preparation methods, in particular to a preparation method of a yellow-bellied tit transparent bone specimen. Background technique [0002] The scientific name of the yellow-bellied titmouse is Parusvenustulus. It is small in size. The head and upper back of the male bird are black, with a white patch on the cheeks and nape of the neck. The lower back and waist are bright blue-gray, and the lower chest to the undertail coverts are yellow. The upper body of the female bird is gray-green, the chin, throat, cheeks and ear feathers are gray-white, and the rest of the lower body is light yellow-green. The yellow-bellied chickadee is a special bird in China. It is distributed in the southwest of Gansu, Taibai Mountain in the Qinling Mountains in the south of Shaanxi, and Funiu Mountain in Henan. This species has been included in the "National Protected Terrestrial Wild Animals of Beneficial or Importa...
