The absorption of root system was the main sources of nitrogen in the plant.The effects of matrix ventilation on the abaorption,transportion and metabolism of nitrogen in the root system of cucmber were discussed deeply.The results showed that contents of ammonium,nitrate,free amino acids and soluble protein in cucumber roots were higher in G1 treatment.Contents of ammonium,nitrate and free amino acids in cucumber roots were the trend of the dropping after the first rising in F1 treatment,but contents of soluble protein was lower11.03%than that of the control.

根系吸收是植物体内氮素的主要来源，本研究深入探讨了基质通气状况对黄瓜根系氮素吸收、运输和氮代谢的影响，结果表明G1通气处理根系的铵盐、硝酸盐、游离氨基酸和可溶性蛋白含量均较高；非通气处理(F1处理)根系内铵盐、硝酸盐和游离氨基酸含量呈先升高后降低的趋势，而可溶性蛋白含量始终较低，比对照降低11.03%。G1处理根系硝酸还原酶、亚硝酸还原酶、谷草转氨酶、谷丙转氨酶、谷氨酰胺合成酶活性均较高；而F1处理的酶活性在处理末期显著降低，其中谷氨酰胺合成酶活性比对照降低33.33%。

At the end of the 1990s, there is breakthrough progress in the phenol-acetone process of the world. Especially development of molecule sieve catalyst for cumene is not only of progress of the technique ,but also possibility of clean-production, Also, sythesization and purification of phenol-acetone have been get improvement largely.
