华氏温标

Today, the most popular temperature scale includes Fahrenheit scale, Celsius scale, Thermodynamics Temperature Scale and International Practical Temperature Scale.

目前国际上用得较多的温标有华氏温标、摄氏温标、热力学温标和国际实用温标。

As per Fahrenheit: Under the standard atmosphere pressure, the melting point for ice is 32 degree while the boiling point for water 212 degree, so the scale is evenly divided into 180 degrees in this range.

华氏温标规定：在标准大气压下，冰的熔点为32度，水的沸点为212度，中间划分180等份每等份为华氏1度符号为℉。

The unit of temperature is the degree Fahrenheit, and 0 ℉ was originally the coldest temperature Fahrenheit could achieve using a freezing mixture of salt and ice.

华氏温标是一种温度计量方式，1715年由德国物理学家 Gabriel Fahrenheit 首创，其单位是华氏度。0 ℉原本是 Fahrenheit 冰冻盐冰混合物所能测量到的最低温度。

SLEEPING BAGS: This is one of the items where cost is usually directly proportional to weight and quality. Many manufacturers (such as Western Mountaineering and Feathered Friends to name a few) produce bags which are rated at 20F and are below 2lbs.

睡袋：这项装备的价格通常是重量和质量是成正比的，许多生产厂商(例如： Western Mountaineering 和Feathered Friends)生产的温标为20华氏度的睡袋但重量却低于2磅。

At a glance, the Celsius scale makes more sense than the Fahrenheit scale for temperature measuring.

摄氏 看上去，摄氏温标对温度测量比华氏温度计更有效。

The assertion expects a temperature value of 32, which is correct on the Fahrenheit scale.

断言预计温度值为32 ，这对华氏温标来讲是正确的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
