温泉文化究竟起源于何处，这个答案也许已年代久远得不可考了。一开始，人类发现温泉，更发现动物在泉水中恢复体力。据说日本人一开始并不知道温泉具有治疗疾病的功能，后来是因为看到一只受伤的小动物在泡过温泉之后奇迹般地迅速复原，这才使他们开始认真地研究起温泉的功能。现代人渐渐把泡温泉作为休闲养生、解压甚至治疗的方法，这种趋势迅速在全球蔓延。那么，温泉英语怎么写呢？
Realize Hot Spring
认识温泉
A hot spring is a spring that is produced by the emergence of geothermally heated groundwater from the Earth’s crust. There are geothermal hot springs in many locations all over the crust of the earth.
Because heated water can hold more dissolved solids, warm and especially hot springs also often have a very high mineral content, containing everything from simple calcium to lithium, and even radium. Because of both the folklore and the claimed medical value some of these springs have, they are often popular tourist destinations, and locations for rehabilitation clinics for those with disabilities.
The water issuing from a hot spring is heated by geothermal heat, i.e., heat from the Earth’s mantle. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. If water percolates deeply enough into the crust, it will be heated as it comes into contact with hot rocks. The water from hot springs in non-volcanic areas is heated in this manner.
Steam Crepuscular rays at Mammoth Hot Springs in active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and erupts in a jet above the surface of the Earth, it is called a geyser. If the water only reaches the surface in the form of steam, it is called fumaroles. If the water is mixed with mud and clay, it is called a mud pot.
依化学组成分类，温泉中主要的成分包含氯离子、碳酸根离子、硫酸根离子，依这三种阴离子所占的比例可分为氯化物泉、碳酸氢盐泉、硫酸盐泉。 除了这三种阴离子之外，也有以其他成分为主的温泉，例如重曹泉（以重碳酸钠为主）、重碳酸土类泉、食盐泉（以氯化钠离子为主）、氯化土盐泉、芒硝泉（硫酸钠离子为主）、石膏泉（以硫酸钙为主）、正苦味泉（以硫酸镁为主）、含铁泉（白磺泉）、含铜、铁泉（又称青铜泉） 其中食盐泉也称盐泉，可依含氯化物食盐的多寡`，区分为弱食盐泉和强食盐泉。
