化長句為短句（實例說明）

在科技英語里，切忌寫大長句，盡量使用簡短的句子，即一個句子表達一個意思。如果句子所表達的意思之間有一定的關聯，可使用分號來連接。

以下句子就太長：

• According to the characteristic of fan-coil air-conditioning systems, this paper derives the cooling formula of fan-coil units based on the heat transfer theories and puts forward a new method to gauge cooling named Cooling Metering on the Airside, which can monitor the individual air-conditioning cooling consumption during a period of time by detecting the parameters of inlet air condition – temperature and humidity – of the fan-coil air-conditioning system as well as the parameters of inlet cooling water provided by the chiller.

可以拆分成幾個句子來表達，如下：

• This paper derives the cooling formula of fan-coil units based on the characteristics of fan-coil air-conditioning systems and heat transfer theories, and puts forward a new method to gauge cooling called Cooling Metering on the Air-side. The new method can monitor individual air-conditioning cooling consumption during a period of time by detecting the condition of inlet air – temperature and humidity – of the fan-coil air-conditioning system as well as the parameters of the inlet cooling water provided by the chiller.

再看下例：

• The gear transmission is grade seven, the gear gap is 0.00012 radians, the gear gap has different output values corresponding to any given input value, non-linearity of the gear gap model can be described by using the phase function method, the existing backlash block in the non-linear library of the Matlab/zdimulink toolbox can be used, the initial value of gear gap in the backlash block is set to zero.

這個長句可化簡為以下形式：

• The gear transmission is grade seven. The gear gap, which is 0.00012 radians, has different output values corresponding to any given input value. The non-linearity of the gear gap model can be described by using the phase function method. The existing backlash block in the non-linear library of the Matlab/zdimulink toolbox can be used; the initial value of gear gap in the backlash block is set to zero.

另一類大長句包含了眾多參數值，這種情況可以把句子寫成列表的形式。

如下句子：

可以改寫成：

又如：

• The clear height of the case is 6.15 meters; the thickness of the roof is 0.85 meters; the thickness of the bottom is 0.90 meters, the overall width is 26.6 meters, the overall length of the axial cord is 304.5 meters, the length of the jacking section is about 148.8 meters; the weight of the case is about 24127 tons.

可以改寫成以下形式：
