Carbonate sediments in all environments are basically products of an ancient biochemical system.
一切环境的碳酸盐沉积物,基本上都是古代生物化学体系的产物。

This and calcium carbonate whisker needle crystal shape relevant, when the system flow, calcium carbonate whisker both translational motion, also have the rotary motion.
这与碳酸钙晶须的针状晶型有关,当体系流动时,碳酸钙晶须既有平移运动,也有旋转运动。

The output voltage of molten carbonate fuel cell (MCFC) stack should be constant in order to ensure the system being operated reliably, effectively and safely.
