Application overview of various microbeam analysis technologies in geology research

Microbeam analysis technology has been popularized to research institutes, universities and various large-scale industrial and mining enterprises across the country, and has played a significant role in various scientific research fields, scientific and technological development and industrial and agricultural production fields.

The basic principle is to focus the laser beam on the micro-area of the sample to melt and gasify it, and then bring the sample particles into the plasma for ionization. Mass filtration is carried out by the mass spectrometry system, and the receiver detects ions with different charge-mass ratios.

This article briefly introduces several technologies and methods that are currently the most widely used in tectonic geology research, including cathodic luminescence analysis technology, transmission and scanning electron microscope technology, EBSD technology, etc. For the basic principles, technologies and scope of application of various methods, please refer to the relevant textbooks and literature.

Doctoral Application Conditions of Shanghai Institute of Microsystems and Applied Technology of the Chinese Academy of Sciences

1. Shanghai Institute of Microsystems and Information Technology Research Founded in 1928, it is one of the earliest famous national comprehensive research institutes of technology and science in China. Since the founding of the People's Republic of China, it has won more than 50 national awards and more than 340 provincial and municipal awards from ministries and commissions.It is the first batch of doctoral and master's degree awarding units approved by the State Council.

2. I) Applicants must have obtained a master's degree and work for more than five years after obtaining a master's degree.

3. The requirements for the postgraduate doctoral examination are: applicants must have obtained a master's degree, a fresh master's graduate or have obtained a bachelor's degree for more than 6 years and have achieved the same education as a master's graduate.

4. The conditions and requirements for doctoral students vary from country to country and region, but usually need to meet the following conditions and requirements: academic background: usually requires the applicant to have obtained a master's degree or an academic background equivalent to a master's degree. Some countries or regions also allow excellent undergraduate graduates to apply for doctoral degrees directly.

Application of microbial fermentation technology

1. Food industry Microorganisms are widely used in the food industry. For example, the fermentation of yogurt is carried out through lactic acid bacteria. And the production of bread, beer, soy sauce, wine and other foods is also completed through the metabolic process of microorganisms.

2. Tea In the fermentation process of tea food, the reasonable use of microbial fermentation technology can improve the quality of tea. Take Pu'er tea as an example. Pu'er tea has a promoting effect on yeast in the fermentation process, which can improve the fermentation efficiency and reliability.

3. Microbial fermentation is widely used in food. Here are some common examples: yogurt and dairy products: yogurt is fermented by adding lactic acid bacteria (such as lactobacillus and thermophilus streptoccus) in dairy cows to milk.

4. Fermentation engineering refers to a new technology that uses modern engineering means to use certain specific functions of microorganisms to produce useful products for human beings, or directly applies microorganisms to the industrial production process. The contents of the fermentation project include the selection of culture, the preparation of culture medium, sterilization, expanded culture and inoculation, fermentation process and separation and purification of products, etc.

5. Modern fermentation engineering, also known as microbial engineering, refers to the use of modern bioengineering technology to use certain specific functions of microorganisms to produce useful products for human beings, or directly apply microorganisms to industrial production processes. Fermentation engineering has been widely used in many fields such as medicine, food, agriculture, metallurgy and environmental protection.

Application of microelectronics in modern electronic science and technology
