主题: 英语中比例关系(正比,反比)的表达 [] |
![]() 在科技文体中,人们常常使用正比或反比作手段来阐明问题,英语该如何说?特撰数例,以飨读者。 I:正比表示法 1. The volume of a gas varies(directly) with (as) the temperature. 气体的体积和温度成正比。 2. The vapor pressure changes with the temperature, the pressure, and kind of liquid. 蒸汽压随着温度、压力和液体种类而变化。 3. The pressure of a gas is(directly) proportional to its absolute temperature when its volume remains constant. 当气体体积保持不变时,气体压力就和其绝对温度成正比。 4. In a constant resistance D.C.(direct current 的缩写) circuit the current will vary directly proportional to(或be in direct proportion to) the voltage.(proportional 或 in…作表语) 在电阻不变的直流电路中,电流是和电压成正比的。 5. It must be noted that the current increases proportional to every decrease of resistance. 必须注意到,电流是与每次电阻减少成比例地增加的。 6. As the temperature of a liquid is raised its vapor pressure increases very rapidly. 液体蒸汽压随着其温度的升高而十分迅速的增加。 7. The more carbon the steel contains, the harder it becomes. 钢的含碳量越大,钢就越硬。 8. With the same current there will be more potential difference with more resistance. 在同一电流情况下,电阻越大,电位差就越大。 9. A solvent will dissolve more solute with a rise of temperature. 溶剂随着温度升高而溶解更多的溶质。 10. With a given resistance, the current varies directly as the voltage. 在给定电阻情况下,电流和电压成正比。 11. The value of the constant C will not vary with any factors. 常数C 值不会随着任何因数而变。 II:反比表示法
