analysis(English: Analysis) It is to decompose things or objects into various parts or attributes from the whole in the mind.Although "analysis" as a formal concept has only been gradually established in recent years, this techniqueAristotle(384-322 BC) has been applied to mathematics, logic and other fields.
(Dynamic) Break something down into simpler components for research, and find out the essential attributes of these parts and the relationship between them: feasibility analysis | analysis of the situation. [Anti synthesis.[9]

analytical chemistryIt is a method to develop and analyze the composition and structure of substances, so that the chemical composition can be qualitative and quantitative, and the chemical structure can be determined.qualitative analysisCan find out what chemical composition is in the sample;quantitative analysisThe content of these components can be determined.When analyzing samples, it is generally necessary to separate different components.Analytical chemistry is one of the most basic training for chemists. The training of chemists in experimental technology and basic knowledge is derived from analytical chemistry.
The methods of analysis can be roughly divided into two categories: classical methods and instrumental analysis methods.Instrumental analysis methods use instruments to measure the physical properties of analytes, such aslight absorption、fluorescence、conductanceEtc.Instrumental analysis methods are often used, such as electrophoresis, chromatographyField current classificationAnd other methods to separate the sample.Contemporary analytical chemistry focuses on instrumental analysis. There are several categories of commonly used analytical instruments, includingAtomic and molecular spectrometer，Electrochemical analysis instrument，nuclear magnetic resonance, X-ray, andMass spectrometer。Analytical chemical methods other than instrumental analysis are collectively referred to asClassical analytical chemistry。Classical method (also known asWet chemistryMethod) often based on color, smell, ormelting pointTo separate samples (such asextraction、precipitate、distillationAnd other methods).This kind of method is often measured byweightorvolumeTo do quantitative analysis.[3]

classical mechanicsThe original expression wasNewtonGiven that a large number of geometric methods andvectorAs a research tool, it is also called vector mechanics (sometimes called "Newtonian mechanics").Lagrange、Hamilton、Jacobian Used by othersGeneralized coordinateAnd variational method, a set of mechanical expression method equivalent to vector mechanics is established.Compared with vector mechanics, the expression method of analytical mechanics is more universal.Many very complex problems in vector mechanics can be easily solved by using analytical mechanics.The method of analytical mechanics can be extended toquantum mechanicsIn systems and complex dynamic systems, quantum mechanics andNonlinearIt has important applications in dynamics.
staycryptographyMedium,frequency analysisIt refers to studying the frequency of letters or letter combinations in text.Use frequency analysis to crackClassical cipher。
The frequency analysis is based on the following principle: in any written language, different letters or letter combinations have different frequencies.Moreover, for any piece of text written in this language, the distribution of characteristic letters is roughly the same.For example, inEnglishMedium, letterEThe frequency of occurrence is very high, andXLess often.Similarly, ST, NG, TH, QU and other two letter combinations appear very frequently, while NZ and QJ combinations are rare.The 12 letters with the highest frequency in English can be abbreviated as "ETAOIN SHRDLU".[5]
mathematical analysis (English:mathematical analysis）The content of higher mathematics, which is different from that of other non mathematical students, is the oldest and most basic branch of analysis, and generally refers toCalculus、Infinite seriesandanalytic functionThe general theory of, etc. is the main content, including their theoretical basis（real number、function、measureandlimitBasic theory of mathematics).It is also a basic course for college mathematics majors.
The contents of mathematical analysis includereal number、complex, real functions and complex functions.Mathematical analysis is evolved from calculus. During the development of calculus to the modern stage, the methods in application were summarized and sublimed into a kind of comprehensive analysis methods, and elementary calculus also includes many basic concepts and skills of mathematical analysis. It can be considered that these application methods are the prerequisite for the generation of advanced calculus.The way of mathematical analysis is related to its geometry, but as long as any mathematical space has a defined neighborhood（topological space ）Or there is a definition of the distance between two objects（metric space）Can be analyzed by mathematical analysis.[7]

semantic analysis (semantic analysis) technology refers to analyzing a long string of words or content from which the summary and general idea of the paragraph can be obtained, or even further, sorting out the meaning of the whole article.This technology can be used to interpretfilm, audio, etcSearch EnginesIt can search for objects other than text, so that users can save a lot of time to watch movies and listen to audio messages, and it can also help users understand the content of movies and audio messages in advance.
Semantic analysis technology was based onsingular value decomposition (Singular Value Decomposing (SVD), Non negative matrix factorization (NMF), etc. In recent years, various types of neural networks (NN) have been used to complete semantic analysis.

Philosophical analysisIt is a general term for many typical application skills of philosophical issues involving "disassembly" (such as analysis) in the tradition of philosophical analysis in western philosophy.Among them, it is almost uncontroversial toconceptAnalysis is regarded as one of the most outstanding skills.
Philosophical analysis refers to the whole exploration and discovery of the way of thinking that relies on the rigorous or necessary divergence of things, events, people, phenomena, and all the tangible and intangible metaphysics, the physical and intangible, and the phenomenon and non phenomenon.[8]
