净举 meaning in Chinese
free lift
Examples
- We decide to develop an equipment of weather balloon puffing to behoove the proper net lifting force automatically . it not only advances the precision of puffing and automatic degree of the weather balloon ' s puffing , but also eases the intensity of labour
我们研制一种气象气球自动充气装置，它能根据具体测量要求，自动将气球充气到应具有的净举力，该装置不仅能够提高充气的精度，而且减轻劳动强度，提高气球充气的自动化程度。 - The former has to be operated in a complex way , while the latter has a tendency to charge too much or not enough , greatly affecting the accuracy of the observation data . moreover , both drive observers so hard that they have to read the metrical data of glass and thermometer , before finding out the proper net lifting force through manual work
前者操作复杂，后者容易造成充气不足或过多，影响观测数据的准确性，而且这两种方法都需要观测人员读取气压计和温度计的测量值，再经过人工查表得出气球应具有的净举力，工作量较大。
