溫泉文化究竟起源于何處，這個(gè)答案也許已年代久遠(yuǎn)得不可考了。一開(kāi)始，人類(lèi)發(fā)現(xiàn)溫泉，更發(fā)現(xiàn)動(dòng)物在泉水中恢復(fù)體力。據(jù)說(shuō)日本人一開(kāi)始并不知道溫泉具有治療疾病的功能，后來(lái)是因?yàn)榭吹揭恢皇軅男?dòng)物在泡過(guò)溫泉之后奇跡般地迅速?gòu)?fù)原，這才使他們開(kāi)始認(rèn)真地研究起溫泉的功能?，F(xiàn)代人漸漸把泡溫泉作為休閑養(yǎng)生、解壓甚至治療的方法，這種趨勢(shì)迅速在全球蔓延。那么，溫泉英語(yǔ)怎么寫(xiě)呢？ ?

? Realize Hot Spring ? 認(rèn)識(shí)溫泉 ? 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. ? 依化學(xué)組成分類(lèi)，溫泉中主要的成分包含氯離子、碳酸根離子、硫酸根離子，依這三種陰離子所占的比例可分為氯化物泉、碳酸氫鹽泉、硫酸鹽泉。 除了這三種陰離子之外，也有以其他成分為主的溫泉，例如重曹泉（以重碳酸鈉為主）、重碳酸土類(lèi)泉、食鹽泉（以氯化鈉離子為主）、氯化土鹽泉、芒硝泉（硫酸鈉離子為主）、石膏泉（以硫酸鈣為主）、正苦味泉（以硫酸鎂為主）、含鐵泉（白磺泉）、含銅、鐵泉（又稱(chēng)青銅泉） 其中食鹽泉也稱(chēng)鹽泉，可依含氯化物食鹽的多寡`，區(qū)分為弱食鹽泉和強(qiáng)食鹽泉。 ?
