This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).

分析《淮南万毕术》所载制冰方法和过程，提出低压下水快速蒸发吸热制冷是"夏造冰"的制冰原理；结冰的部位不是传统观点所认为的瓮底，而是在瓮口的嫌上；指出要实现"夏造冰"，需满足三个条件：相对湿度低（低于26%）、瓮的容积大（100升左右）、空气的温度适当（20℃左右）。

The reaction of sorbents was affected markedly by relative humidity and less pronouncedly by CO2 concentration.

Pear leaf psylla psylla pyrisuga Forster were fed on Pyrus pyriforis Nakai leaves at 20-30℃and at 60-90% of relative humidity with 25℃. The results showed that the optimuM temperature for the development of the eggs,nymphs and the whole generation was shown to range from 20. 0-22.5℃, 22.5-25℃. and 22. 5-25℃, respectively. The optimun temperature for the reproduction of the female adults was 25℃.

以砂梨叶作饲料，研究了20、 22.5、 25、 30℃四种温度和在25℃条件下，60％、70％、80％、90％四种相对湿度对梨木虱Psylla pyrisugaForster生长发育和繁殖的影响，结果表明梨木虱卵期、若虫期和全世代生长发育最适温度分别为20－22.5℃，22.5，25℃和22.5－25℃，雌成虫繁殖最适温为25℃。

Diurnal changes of Pn and environmental factors (photosynthetic available radiation and air temperature and relative humidity) and physiology factors (stomatal conductance and transpiration rate and intercellular CO2) in leaves of puna chicory were measured using CI-340 portable photosynthesis system.

利用CI-340便携式光合仪，测定了普那菊苣叶片净光合速率和环境因子（气温、光合有效辐射、空气相对湿度）、生理因子（蒸腾速率、胞间CO2浓度、气孔导度）的日变化；通过回归和通径分析，考察了影响因子对净光合速率日变化的影响。
