What Is a Life Support System?

The life support system is based on the organic world (including plants, animals, microorganisms, and human society), and the inanimate nature (including solar energy, geothermal energy, atmosphere, water, soil, rocks, and their interactions). Products, intermediate products, combined environment and conditions), the coexistence of interdependence, mutual influence, and mutual penetration of the two, the coupling relationship of mutual conflict, complementarity, opposition, transformation, coordination, etc., together constitute the basic skeleton of the life support system.

Its research contents roughly include: the combination of elements in the inorganic world and the conditions of the combination of elements can provide the ability to survive and develop in the life world, mainly emphasizing the contribution of the inorganic world; Impact and regulation mainly emphasize the transformation of life. The comprehensive characterization of the interaction between the two mainly emphasizes the coupling. ^[1]

Definition 1: Life-sustaining system composed of the interaction between the earth's organic world, human society and inorganic nature.

Applied disciplines: Geography (first-level discipline); General introduction to geography (second-level discipline)

Definition 2: Equipment system that provides a safe and comfortable living environment for divers in pressurized cabins to ensure their normal life activities and working ability.

Applied disciplines: marine technology (first-level discipline); marine technology (second-level discipline); marine underwater technology (third-level discipline)

Definition 3: Including solar radiant heat, air, water, soil and nutrients. They provide a place, food and energy for living things.

Applied disciplines: ecology (first-level discipline); ecosystem ecology (second-level discipline)

Definition 4: Earth's surface system on which humans and other living things depend.

Applied disciplines: resource science and technology (first-level discipline); resource ecology (secondary discipline) ^[1]

Can be understood as:

1. The combination and combination conditions of elements in the inorganic world can provide the ability to survive and develop in the life world, and mainly emphasize the contribution of the inorganic world

2. The influence and adjustment of the life world on the inorganic world during its survival and development process, mainly emphasizing the transformation of the life world;

3. A comprehensive description of the interaction between the two, with emphasis on coupling. ^[2]
