(1) 力求简捷
at a temperature of 250℃ to 300℃ → at 250 to 300℃
at a high pressure of 2 kPa → at 2 kPa
has been found to increase → increased
from the experimental results, it can be concluded that → the results show
(2) 能用名词作定语的不用动名词作定语，那用形容词作定语的不用名词作定语
measuring accuracy →measurement accuracy
experiment results →experimental results
(3) 可直接用名词或名词短语作定语的情况下，要少用of句型

(5) 一个名词不宜用多个前置形容词来修饰，可改用复合词，兼用后置定语
thermal oxidation apparent activation energy →
apparent active energy of thermo-oxidation
一个典型示例
A detailed study of the melting behavior of oriented isotactic polypropylene has been carried out using differential scanning calorimetry. The orientation in isotactic polypropylene was produced by extruding it in solid phase. At extrusion ratio (ER ) greater four, two melting peaks were observed. With increasing ER, the lower temperature peak was found to shift to higher temperature. The corresponding shift in the higher temperature peak was much less. It is shown that these peaks originate in the melting of crystalline species having different degrees of crystal disorder and stereo-block character.
