Results:(1)Plasma FC concentration in undialyzed patients with CRF was significantly higher than that in normal subjects(P.05),and it was closely correlated with blood urea nitrogen(r=0.666 0) and uric acid(r=0.642 0,P.05),not correlated with serum creatinine.

结果：(1)慢性肾衰保守治疗患者血浆FC浓度明显高于正常人(P.05)，并与血清尿素氮、尿酸显著相关(r=0.666 0，r=0.642 1，P.05)，与血清肌酸酐无关。

Wheat straw powder amendment induced one times and more emissions of N 2O and CH 4 than no its application, and hence, even only from the standpoint of diminishing soil source greenhouse gases emission, applying unmatured composted organic materials with urea is an inappropriate fertilization system.

不论是N2O还是CH4的排放总量，施麦秸粉的都比未施的高出1倍和更多。因此，单从土壤源温室气体排放的角度看，将未腐熟的有机物料与尿素共施，并不是一种适宜的施肥制度。

The uron content was determined and the effects of pH value, temperature, reaction cycle and catalyst species on the Uron content were also discussed by FTIR quantitative analysis by uronizing urea-formaldehyde derivatives at the beginning of the reaction before the synthesis of UF resin.

采用在脲醛树脂合成初期对尿素－甲醛衍生物进行Uron化反应后，再进行UF树脂合成的技术方法，通过FTIR定量分析，研究了不同pH值、反应温度、反应时间及催化剂种类对尿素与甲醛成环化反应的Uron相对值的影响。

The results show that urea-formaldehyde resin can effectively capsulize an organic material of paraffin.

以石蜡为囊芯，尿素-甲醛树脂为囊壁，运用原位聚合法合成相变储能微胶囊材料。

In addition, a further study was made of the technique of extraction, isolation and purification of GLA. The factional extraction used in the laboratory with n-hexane and ethanol was changed into the whole extraction of 6〓 solvent, which simplified production technique and reduced cost of production. The fungal lipid extracted from the fermentation in the medium-scale test was concentrated by the urea adducting method with methanol as solvent, at 75～80℃ for 3 hours. After GLA had been adducted twice, the content of GLA came up to 84. 25%, around a twelfth as much as the original concentration.
