Observation under single polarized mirror: crystal shape, solution, protrusion, color and multicolor of minerals. ( 2) Observation under the orthogonal polarizing mirror: interference color, double refraction, extinction type, extinction angle, ductility symbol, double crystal of minerals. ( 3) Observation under the cone mirror: 1 Distinguish homogeneous and non-homogeneous minerals according to the existence of an interferogram.
Observe the crystal shape, solution, envelope characteristics, etc., and determine the solution angle, color and protrusion level. 2) Observe the extinction type, determine the ductility symbol, observe the double crystal type, etc. 3) Determine the axiality of minerals and determine the photometric symbol. Observe the colors of No, Nm or Ng and Np under a single polarized mirror.
Write the multicolor formula and the absorption formula. In thin rock sheets, the refractive index range of minerals can only be roughly estimated according to the protrusion level. To accurately determine the main refractive index value of minerals, oil immersion or other methods are required. After systematically determining the optical properties, consult the relevant optical mineral identification manual or identification chart to determine the mineral name.
Protrusion level Observe the obviousness of the edge and rough surface of the mineral sheet, the height of the protrusion and the direction of movement of the Baker line. Comprehensively judge the protrusion level and estimate the general range of mineral refractive index. Observe the phenomenon of flash protrusion.
The specifications that should be followed in the description process can refer to the following descriptive examples. Perilla pyrite self-shaped - semi-self-shapedThe short column is upright, with two groups of complete solutions, and the angle of understanding is 87° or 93°. The multicolor is still obvious, Ng = light green, Nm = light yellow, Np = light red.

Junior college graduation self-assessment model essay 1 In the past three years, through my continuous efforts, I have mastered the skills and methods of learning, successfully become the master of learning, exercised my strong perseverance that I usually lacked, cultivated my excellent quality of hard work, and made my lifelong learning It has laid a very good foundation.
1. Enter the Beijing Fire Association system and find the score inquiry system. Enter the vocational skills appraisal score inquiry system of Beijing Fire Association, enter your name and ID number, and click OK to get the query results.
2. Verification of the achievements of building firefighters. Log in to the website of the Vocational Skills Appraisal Center of the Ministry of Human Resources and Social Security, and enter your ID card and certificate.The book number, admission ticket number, name and other information can be used for score inquiry. As for the website, it's good to ask Du Niang.
3. Enter the correct certificate number: 14040219660729XXXX; enter the correct certificate number: 080504000040XXXX; select [Query]. Display the correct information of this examinee in a new window.
1. In the traditional classification identification, the main basis of microbial classification identification is morphological characteristics, physiological and biochemical reaction characteristics, ecological characteristics, serological reactions, sensitivity to bacteriophages, etc. . During the appraisal, we take these bases as appraisal items and carry out a series of observations and appraisal work.
2. Different meanings have different uses. The meaning is different. Testing refers to the activity of determining one or more characteristics of the qualified evaluation object according to the procedure. Identification is to identify and verify the authenticity, superiority and inferiority of things. The use is different.
3. Conduct physiological and biochemical tests: including the utilization of carbon and nitrogen sources, adaptation to the pH of the growth environment, sensitivity to certain antibiotics, etc. These experiments can help identify the types and characteristics of microorganisms.
1. Comprehensive systematic identification of minerals under microscopy One of the main purposes of mineralography is to identify metal minerals under the mineral phase microscope. There are nearly a thousand kinds of metallic minerals in nature, and some properties of many minerals are very similar. There are no prominent identification characteristics, and it is not easy to immediately determine the name of the mineral.
2. Mineral morphology. Monomer morphology of minerals: Under certain external conditions, mineral monomers always tend to form specific crystals. Mineral identification and morphological characteristics are called crystallization habits. For example, quartz crystals are columnar. Physical properties.
3. Minerals in nature can be divided into transparent minerals and opaque minerals according to the degree of transparency. The identification of opaque minerals is mainly to identify the physical properties of minerals such as mineral morphology, color, luster and understanding by blocking the incident light and using reflected light.
4. Characteristics of observation under the conical mirror: use the combination of orthogonal polarization and concentrator to observe the interference map, determine the positive and negative of mineral axiality and photogenicity; estimate the size of the optical axial angle (2v). The identification of mineral drugs under a polarizing microscope is carried out using thin slices and debris.
5. Main identification characteristics: gray-blue fibrous (Figure 20-8);The texture is soft, the splitting is good, and the tensile strength is high.
1. You can contact the appraisal agency to inquire about the appraisal results and request a written appraisal document. Log in to the official website of the judicial administrative department to inquire about the registration of judicial appraisal institutions and personnel. Log in to the official website of the provincial judicial administrative department to inquire about the roster preparation and announcement of judicial appraisers and judicial appraisal institutions.
2. You can check it online. The regulations vary from place to place. Some places can be checked, and some places can't. After the results come out, you will receive an appraisal report, and you can open it and check it by yourself.
3. Legal analysis: The period when the person is blacklisted, it is not allowed to enter the professional appraisal institutions entrusted by the People's Court, the alternative list of professionals and the relevant information platform. The people's court shall make full use of the entrusted appraisal information platform to strengthen the management of the entrusted appraisal work. In administrative litigation, the people's court shall entrust the appraisal and refer to these provisions.
4. Legal subjectivity: If there is any objection to the appraisal result, submit a review appraisal to the local labor appraisal committee at the next level within 15 days of receiving the appraisal conclusion. If it is a labor capacity appraisal made by the labor capacity appraisal committee of provinces, autonomous regions and municipalities directly under the Central Government, this is the final result, which can only be accepted, and there is no other way.
