海洋浮游藻类的生长总是受到一些东西的限制,这些东西可能是光,也可能是相似的营养物质比如硝酸盐或者磷酸盐。
The growth of plankton in the sea is always limited by something. It may be light, or a familiar nutrient such as nitrate or phosphate.

适合大型藻类细胞增殖的光生物反应器需要五个基本因素:光照、温度控制、气体传输、营养物质传输、混合。
Photobioreactors suitable for macroalga cell cultivation must offer five fundamental factors:illumination, controllable temperature, air transfer, nutrients transfer, and mixing.
在有光的条件下,浮游藻类和一些光自养生物对沉积物水界面溶解态的营养盐的直接吸收,从而减少了上覆水中可与沉积物可交换的营养盐的含量;
Many phytoplankton and autotroph absorb the DIN of the bottom water that decrease content of DIN in bottom water and change the fluxes of the DIN.
传粉者、真菌侵染、机械损伤、园艺措施、光、温度、水分、矿质营养和糖等是影响花色的外部因素。
External factors such as pollinators, fungal infection, mechanical damage, horticultural measures, light, temperature, water, mineral ions, and saccharides influence flower color.
留意储存以下四样食品的期限。因为:某些营养成分无论是暴露在氧气中(通过空气),或是热气中(来自煮食)和光之中都变得不稳定。
Keep track of how long you store these 4 items. Here's why: certain nutrients are unstable when exposed to oxygen (from the air), heat (from cooking) and light.
