Nitrogen forms in compound fertilizer affected biomass accumulation of maize too,and the highest dry weight of shoot and root was found in the plants supplied with compound fertilizer containing 100% urea nitrogen in Udic Isohumisols,and mixed nitrate and ammonium in Udic Cambosols.

生长45 d玉米苗的地上和地下部的生物量，在黑土上均以全酰胺态氮的配方最高，地上部干重较其他配方增加10%左右；而在潮土上则以铵态氮与硝态氮配方的效果最好，铵态氮和酰胺态氮混合的配方在2种土壤上均较差。

The results showed as follows:Maize grown in the treatment of compound fertilizer containing urea alone had significantly lower germination rate than the maize receiving mixed CO(NH2)-N/NH4+-N or mixed NO3——N/NH4+-N in compound fertilizers in Udic Isohumisols.However,there was no significant affect of nitrogen forms on maize germination rate in Udic Cambosols.

结果表明，在黑土上，施用酰胺态氮为单一氮素形态的复混肥料时，玉米的出苗率明显下降；而用部分铵态氮替代酰胺态氮后制成的混合态氮和由铵态氮与硝态氮构成的复混肥对玉米的出苗率影响较小；不同氮素形态配比的复混肥对潮土上生长的玉米出苗影响较小，各处理的出苗率可达到90%以上。

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。

Methods Twenty-two patients with mild pre-eclampsia, 28 with severe pre-eclampsia, 10 with eclampsia as well as 30 healthy pregnant women and 20 healthy unpregnant women were determined for GP Ⅱb/Ⅲa by flow cytometry and for urea nigrogen, creatinine as well as uric acid by full-automatic biochemical analyzer, and the results were compared.

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.
