Wengan, formerly known as Huang Huihong, was born in February 1927 in a peasant family in Huaxian County, Guangdong Province. Wengan was young and intelligent. He entered Guangzhou Yushan middle school in 1936 at the age of 10. In 1938, the Japanese invaders occupied Guangzhou, and their hometown was occupied by the Japanese invaders. Their families were separated. Soon after, their mother and younger brother were wounded in the Japanese invaders' sweeping. Wen Gan was in exile, miserable and miserable. His country and family hatred were buried in his young heart. In 1940, accompanied by his cousin, he crossed the blockade and went to the rescue team for children in the war zone of Guangdong Province. Later, he was sent to the first branch of the Guangdong wartime children's reformatory and was soon promoted to the Experimental Middle School of the hospital. The hospital implements the policy of combining management, teaching, nursing and health, and integrating family, school, camp and field. Students learn and produce and save themselves at the same time. Wen Gan's spirit of hard work and self-reliance has been tempered to a certain extent. In the winter of 1941, the Guangdong provincial government sent Wen Gan to Chongqing to study in the Navy School of Chongqing national government, and he was enrolled in the 12th navigation class. After the victory of the Anti Japanese War, he moved eastward with the school and was incorporated into the newly established Qingdao Naval Academy, which is a 37 year class. He graduated in 1948. After graduation, he was kept in school to work.
In June 1949, Wen Gan left the former Navy and went to Hong Kong to participate in the study and activities under the leadership of the Hong Kong Underground Party General Branch of the East China Bureau of the Communist Party of China. In October of the same year, the people's Republic of China was founded, and was sent to Qingdao port as the first batch of port superintendents of Qingdao port. Wen Gan made unremitting efforts to safeguard national sovereignty and establish the port supervision system of a sovereign state. In 1950, when the Korean War broke out, he responded to the call of the government and joined the navy of the Chinese people's Liberation Army. He was successively assigned to the third Naval School as the head of the navigation discipline and the chief navigation instructor. In 1957, he was transferred to prepare for the construction of the naval high school as the head of the astronomy and navigation instructor of the school. He has served in the Navy for more than 14 years. He has taught seven courses in the third Naval School and the naval high school. He has made great contributions to the establishment and personnel training of the Navy's speedboat troops and the teaching reform of naval colleges and universities.
In February 1964, Wen Gan transferred from the army to Dalian Fisheries College (the predecessor of Dalian Ocean University) as the director and lecturer of the navigation teaching and research section, and taught astronomy and navigation. In the first year, he won the title and award of advanced teacher. During the "Cultural Revolution", the peasants were sent to the countryside to participate in agriculture and well drilling. On the one hand, they were engaged in heavy drilling work day and night. On the other hand, they also grasped the spare time to learn geological knowledge, analyze rock strata and find water sources. When he and his colleagues drilled clear spring water from more than 100 meters underground on the North beam of Fuxian County, which is known as Huoyan mountain, and the well drilled in Qiding mountain of Jinxian County turned a large area of arid hillside into a vegetable base for artesian irrigation, they were highly praised and welcomed by local farmers.
When Wen Gan returned to school in 1972, he continued to spare no effort in teaching reform and academic research. In 1976, he successfully studied the simple astronomical positioning method in China's sea area and compiled the Chinese solar ship line table and the Chinese stellar ship line table. In 1977, Wen Gan was rated as an excellent teacher in Liaoning Province, an advanced scientific and technological worker with great contribution by the National Science Conference, and won the major scientific and technological achievement award of the National Science Conference. Wengan was promoted to associate professor by Liaoning Provincial Government in 1977, and was awarded professor in 1980. Wengan was the director of the Department of Marine Fisheries of Dalian Fisheries University in 1979, vice president in 1980, and presided over the administrative work of Dalian Fisheries University in 1981. He was appointed president of Dalian Fisheries University by the State Council in 1983 and held the post until June 1991.
Academic contribution
Education
As early as 1950, Professor Wen Gan participated in the preparatory work of the naval torpedo speedboat school and the naval high school. From 1951 to 1964, he taught in the Naval Academy. He worked as a navigation teacher in the captain class, the captain class, the navigation business class and the foreign students class. He compiled and published the teaching materials such as "speed boat navigation", "speed boat manipulation", "astronomy navigation", "navigation mathematics" and "naval tactics". At the same time, he established a new astronomy navigation teaching system, which was adopted by the president of the Navy and Fisheries Academy Use. He was awarded eight times for outstanding teaching achievements in the Navy, and was rated as a third-class meritorious official, advanced worker, five good teacher, etc. He presided over the development of "navigation slide rule" and "teaching planetarium", which won the Navy outstanding scientific research achievement award and outstanding scientific research achievement collective award respectively. From 1980 to 1991, he was in charge of Dalian Fisheries University (now Dalian Ocean University). He put things right and cured the internal and external trauma caused by the ten-year catastrophe. The university has been upgraded from a junior college to an undergraduate and has the right to grant a master's degree. The scale, specialty, equipment and infrastructure of the college have increased 3-4 times, and it has been rated as Dalian civilized school.
Scientific research
In order to facilitate the positioning of fishing vessels at sea, Professor Wen Gan developed the "simple astronomical positioning method in China's sea area" in the 1970s, which is considered to be "easy to learn, easy to understand, easy to master, easy to check and calculate, less error, one generation of three meters for many years, meeting the requirements of high accuracy". In 1978, the project won the "major scientific and Technological Achievements Award" of the National Science Conference, and Professor Wengan was awarded the honorary title of "advanced scientific and technological workers who have made great contributions (national model worker)". In the 1980s, he presided over the research of "standardization of fishing vessel navigation work", most of the results were adopted and promulgated by the national authorities. In order to meet the needs of the development of China's pelagic fishery, in 1995, he commercialized the achievements of the "computer system for fishing vessel navigation" which he has been in charge of for many years, becoming the first domestic electronic chart and navigation software system equipped with fishing vessels in China. In 1998, it was appraised by the Ministry of agriculture and reached the international advanced level, which filled the blank of navigation computer for fishing vessels in China. Some of the contents were first created at home and abroad. The achievements of this project won the second prize of "science and technology progress" of the Ministry of agriculture in the same year. On the basis of "computer system for fishing vessel navigation", Professor Wen Gan later presided over the development of "ship navigation computer", "Chinese communication system of international satellite communication C station", "ship electronic chart, satellite communication, navigation and monitoring command system" and "integrated system of electronic chart, navigation and maritime information", etc., and made many types and models of products, which are widely used in China It is widely used in internal fishery system, marine system, offshore oil system and shipping system, and is welcomed by users. The project has won a number of provincial and municipal scientific research achievement awards, and has been approved as "National Torch Program project".
Professor Wen Gan's research achievements promote the modernization of navigation and fishing technology, effectively promote the development of production, and enrich and improve the teaching practice content. His main works include: Chinese solar ship position line table, Chinese star ship position line table, simple astronomical positioning method in China Sea area, astronomical positioning, astronomical navigation, astronomical navigation and radio navigation, etc. Recently, the dialectics of teaching, written by Comrade Wen Gan on the basis of decades of teaching experience, has also been included in the large-scale literature of "seeking truth pioneers: Theory and practice of the sixty year development of the Republic".
Achievement and honor
Navigation work often requires a lot of tedious mathematical operations, causing great trouble to the navigators. In 1956, Wengan developed a special slide rule for navigation. It can not only carry out simple calculation according to the special formula for navigation, but also carry out conversion and addition and subtraction of navigation direction. It is easy to carry and use. For example, the conversion of a true course or azimuth to a compass course or azimuth does not need to look up the self deviation table, or observe the vertical angle of a target to find the distance, and so on. It only needs to pull a ruler once to get the answer. In 1956, the achievement was selected to participate in the Navy's scientific and technological achievements exhibition and won the Navy's outstanding scientific and Technological Achievements Award.
In the late 1950s, Wen Gan was in charge of teaching astronomy and navigation in the Navy high school. The main problem to be solved in astronautical navigation is to determine the position of a ship at sea with the sun, moon and stars. Therefore, students must recognize celestial bodies, establish the concept of celestial coordinates, and master the knowledge of celestial motion. Because the sky changes with latitude and season, in a certain area, only a part of the celestial body can be seen at night
