As an example, different temperatures effects on loss pressure along oil-pipe are calculated. The results display that loss pressure along oil-pipe changes little during temperature increasing.

作为算例，分别计算了不同温度下油管内流体沿程压力损失的情况，结果表明：温度对沿程压力损失影响较小。

People under too much pressure would sometimes suffer from muscle aches, headache, tiredness, loss of appetite and so on.

压力太大的人有时候会有肌肉疼痛、头痛、疲劳、食欲不振等症状。
