According to the conventional hypothesis, the earliest living cells emerged as a result of chemical evolution on our planet billions of years ago in a process called abiogenesis. 根據傳統的假說(shuō)，最初的活細胞，肇生于數十億年前地球上的化學(xué)演化過(guò)程，這種說(shuō)法稱(chēng)為無(wú)生源說(shuō)。
Deformation Hydrogeochemical modeling is an important tool in hydrogeochemical studies.Ground water evolution and water cycle in deep earth can be confirmed by the modeling. 摘要水文地球化學(xué)模型是目前水文地球化學(xué)研究的重要工具，通過(guò)模擬可以確定地下水系統中的水化學(xué)演化過(guò)程，揭示地球深部的水循環(huán)機理。
Chemical reactions are the basis of chemical evolution. 無(wú)處不在的化學(xué)反應是化學(xué)進(jìn)化的基礎。
They study the evolution of the universe. 他們研究宇宙的演變。
International trade reflects this evolution. 國際貿易反映了這種演變。
