Forensic science is defined as applied to the theory and technology of natural sciences, such as medicine, biology and chemistry, in the field of forensic science in which the basic theoretical knowledge of forensic science is presented. The development of forensic science has its origins in ancient autopsies and judicial practice, and with the development of medicine and jurisprudence, an independent system of disciplines has evolved. Modern forensic science developed rapidly in europe in the nineteenth century and is gradually becoming an important part of the judicial system worldwide. The definition of forensic medicine and the development of forensic forensic science, which are primarily part of the judicial system, provide evidence and leads for the investigation, trial and prosecution of cases through the examination and identification of bodies, living bodies, physical evidence, etc. Forensic criminal investigation plays an important role in criminal investigations, helping the police to identify key information, such as the nature of the case, the method of its commission, the time of its commission, etc., by conducting on-site surveys, body examinations, physical analysis, etc. Legal development and implementation of forensic research and expert opinions can provide a reference and basis for law development and enforcement and promote justice and the rule of law. Forensic science has a place in the judicial system where forensic medicine and other disciplines are closely related to forensic medicine and medicine, on which medical knowledge is based. Forensic science requires the examination and identification of bodies, living things, etc., using medical theory and technology. Jurisprudence is interdependent with jurisprudence, which provides the legal basis and norms for forensic science, while forensic science provides evidence and leads for jurisprudence. Criminal investigation forensics works closely with criminal investigation sciences, which provide case information and investigative direction for forensics, while forensics provides scientific evidence and technical support for criminal investigation. Forensic science, such as psychology and sociology, is also linked to subjects such as psychology and sociology, which can provide psychological analysis, social background, etc. For forensic science. Basic theoretical knowledge 02 catalogue basic processes for the morphological, structural and functional activity of organs of the human system and mechanisms for regulating the phenomenon of corpses and their relationship to diseases and deaths in the forensic anatomy and physiology fundamentals of forensic medical significance, and the types, characteristics and diagnosis of common diseases in the forensic medical sense 01, the symptoms of which are based on the principles of pathology and the toxicology of the types of common diseases, as well as on the analysis of typical cases of poisoning of 010203 and the analysis and discussion of the classification, source and toxic effects of poisons, the mechanism for field survey and forensic techniques 03 catalogue to ensure physical integrity, authenticity and prevent the destruction or contamination of evidence. The principle of on-site protection follows the procedure established by law and scientific, objective and comprehensive surveys are conducted. The principles of surveying include a variety of means, such as observation, recording, mapping, photography and video, to gather information on the ground. The survey methods are field protection, survey principles and methods, depending on the manner and characteristics in which they are formed. The trace classification method technique uses physical, chemical and other methods to show and extract traces, which are compared and analysed to determine their relevance to the case. Trace detection techniques play an important role in criminal investigations and can be used to identify suspects, modus operandi, etc. Trace detection techniques include substances containing human cells or tissues such as blood, semen, saliva and hair. The type of biological evidence is extracted in accordance with the characteristics of the different items of evidence, using wipes, cuts, scratches, etc. Biological evidence of the extraction method should be kept in the dry and cool areas to avoid contamination and deterioration. At the same time, detailed information on the origin of the exhibits, their timing should be recorded for subsequent analysis and comparison. The physical examination of the body by means of biological material extraction and preservation methods and the identification of the cause of death technique 04catalogue to examine the appearance of the body for injuries and pathologies, to record the physical examination of the body and the recording of the methods of recording the body to take note of the body's coldness, the marks of the body, the carcasses, corruption, etc. And to infer the time of death. The body was carefully examined in terms of area, morphology, size, colour etc., identification of pre-mortem and post-mortem injuries, analysis of the injury and the manner in which it was caused. Specific marks on the body, such as ligature marks, bite marks, needle holes, etc., should be recorded in detail in terms of location, morphology and characteristics for subsequent analysis. Detailed observations and records of the body's height, weight, size, colour, hair, nutritional status, etc., were made to understand the general state of life of the deceased. The chest cavity is opened in accordance with the prescribed cut and sequence and internal organs are exposed. The body is removed individually from the chest cavity, weighing, measuring and observing, and attention is paid to the disease and injury of the organ. Organ extraction and examination of tissues and organs are made in slices to observe changes in organizational structure and cell form through microscopes. Slice production is organized to collect samples of relevant organizations and body fluids and to conduct poison testing and analysis to determine if poisoning is present. A comprehensive analysis of the body's appearance, internal organ autopsy, tissue tablets and toxicology results was carried out in the laboratory and internal organ autopsy techniques, and the cause of death was determined in conjunction with information on site surveys and case studies. The cause of death is based on the classification of causes of death into natural deaths, accidental deaths, suicides and homicides, which provide the basis for subsequent cases. The classification of causes of death is carried out in accordance with established procedures and criteria to ensure the accuracy and impartiality of the results. At the same time, the parties concerned are contacted to explain their concerns and misperceptions. 05catalogue123 forensic medicine can determine the type of injury, such as contusion, fracture, internal haemorrhage, etc., by conducting a detailed physical examination of the injured person. The degree of injury can be assessed by forensic medicine on the basis of the clinical performance of the injured person, visual examination and laboratory results, such as minor injury, serious injury, fatal injury, etc. The assessment of the extent of the injury, combined with an accident site survey and injury to the injured person, allows forensic science to analyse the relevance of the injury to the accident and to provide a basis for the determination of liability for the accident. The assessment of the loss of work capacity in traffic accidents is carried out by forensic medicine to assess the extent of the loss of work capacity, such as partial incapacity, total incapacity, etc. In the case of an injury to work or an injury to work or other illness caused by an injury to work, forensic science may determine the causal link between the injury and the disease. Recommendations for rehabilitation and re-employment, depending on the particular situation of the injured person at work, can be used by forensic medicine to provide rehabilitation and re-employment advice to help the injured person reintegrate into society. In the case of medical disputes, forensic medicine may determine whether there has been a medical error, such as an improper operation or an error in the use of medication. The assessment of the extent of the damage to the patient can be made by forensic science, including physical damage, moral damage, etc., to provide a basis for compensation. The analysis of the relevance of the medical act and the injury results, combined with the assessment of the medical fault and the extent of the patient's damage, allows forensic science to analyse the relevance of the medical act to the injury results and to provide a basis for the division of responsibility in medical disputes. The division of responsibilities in medical disputes is based on challenges and future trends, such as the upgrading of catalogue technology as the technology progresses, and the upgrading of forensic science as it evolves, how to keep pace with technological developments and ensure the accuracy and reliability of the results. Interdisciplinary cooperation in forensic science involves a wide range of disciplines, such as medicine, law and biology, and how effective interdisciplinary cooperation can be achieved to improve the efficiency and accuracy of identification. The collection and preservation of evidence ensures the accuracy and completeness of site surveys and evidence collection and avoids damage to or contamination of evidence as a result of improper operations. One of the most important technical tools in the field of forensic science has been the current challenge of molecular biology technology 01 dna analysis, which provides strong support for the detection of cases through dna matching that allows for the accurate identification of individuals. Digital technology 02 digitizes functions such as remote identification, three-dimensional reconstruction, and improves the efficiency and accuracy of identification, while also providing new tools for forensic education and training. Artificial intelligence and machine learning-03 artificial intelligence and machine learning techniques can be applied to image identification, data analysis, etc. In the field of forensic science, improving the efficiency and accuracy of identification. Advances in science and technology influence future trends in forensic science, which are expected to lead to more accurate identification in the future, with the development of precision medicine, by paying more attention to the impact of factors such as individual differences and genetic variability on results. The digital and intellectual development of future forensic science will focus more on digital and intellectual development, using advanced technological means to achieve such functions as remote identification, automated analysis and greater efficiency and accuracy of identification. Interdisciplinary cooperation and the integration of future forensic science will focus more on interdisciplinary cooperation and integration, working more closely with the fields of medicine, law, biology and other disciplines to promote the development of forensic science。the combination of precision medicine and forensic science is appreciated
