Requirements in drying process improvement of FeSO4·H2O, effects of high temperature medium, material temperature, air exhaust temperature and dust removal system on product quality are introduced.

介绍了一水硫酸亚铁生产中干燥工艺改进的要求，着重介绍了高温介质、物料温度、排风温度、除尘系统等对产品质量的影响。

The viscosity of the liquid medium reflects the ease of mobility, high viscosity, friction will increase, reducing output power, a waste of energy and have a high temperature.

液体的粘度反映了介质流动的难易程度，粘度过高会增加内摩擦阻力，降低输出功率，浪费能量，并产生过高的系统温度。

So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity.

所以选择不锈钢材质的高粘度泵是一定要注明具体的使用温度，及介质的润滑性。

An assessment of the impacts of climatic change in Latin America and the Caribbean supported by reliable data suggests that ??climate changes during the last century have included an increase in the surface medium temperature, particularly in medium and high latitudes, and changes in precipitation quantity and intensity in several countries of the Region (Southern Brazil, Paraguay, and Argentina).
