Embodiment 1
[0020] figure 1 It is the implementation process of the plant cultivation method provided by the embodiment of the present invention, which is described in detail as follows:
[0021] In step S101, the selected lump coal light sheet is placed on the paper sheet;
[0022] In the embodiment of the present invention, the lump coal light sheet can be an ordinary light sheet, and the size is a conventional size: 6*4*1cm. After selecting the light sheet, pay attention to keeping the smooth surface clean. Place the coal light film on the brownish-yellow backing paper, and select an appropriate reference scale next to the light film.
[0023] In step S102, utilize the photographing device to photograph the block coal light film;
[0024] In the embodiment of the present invention, a professional high-resolution SLR digital camera (not a card camera) is selected, a 90mm fixed-focus macro lens is installed, and placed on a tripod stand. Choose an angle that can clearly show the gloss...

The invention discloses a high rank coal maceral observation method. The method comprises the following steps of placing a selected lump coal polished section on paper; photographing the lump coal polished section by a photographing device, and numbering and storing a photographed picture; determining a coal maceral marker and relative content according to the microscope observation result and the submicroscopic observation result; and performing qualitative and quantitative research on the high rank coal maceral through a calibrated marker. In combination with microscope observation, the method has the advantages that the submicroscopic distribution characteristics of the high rank coal maceral can be effectively and continuously identified, the spatial contact relation of the maceral is judged, the efficiency of coal maceral observation is improved, the difficulty is lowered and the observation reliability is improved.
Description
technical field [0001] The invention relates to the field of microcomponent observation, in particular to a method for observing microcomponents of high coal rank coal. Background technique [0002] The observation of coal microcomponents is the basis of coal phase analysis. At present, the microscopic composition observation technology of high coal rank coal is mainly based on microscope observation. The classic microscope analysis technology observes the microscopic composition of coal, which has the characteristics of large magnification and clear microscopic characteristics. However, the diameter of the field of view of the microscope is generally 0.2mm-5mm, and the observation of the field of view range of 50mm-35mm with complex development of lump coal light coal components can only be observed independently by dividing it into many small areas. It is very inconvenient to study the spatial combination relationship and quantitative statistics of high-rank coal componen...
