Further exploration in this field would be worthwhile.

14名非胰岛素依赖型糖尿病患者,经三个月静气功指导和锻炼后,血清HDL_2-ch自11.5±7.3升为13.1±8.67(P<0.05)和HDL_3-ch自30.43±4.59升为33.26±5.85(P<0.05)明显升高,TG显著降低,可推测静气功锻炼对防治糖尿病人常见的心血管并发症有一定意义。这类病人HDL_2-ch水平与血糖水平成显著负相关,故HDL_2-ch升高可望对其血糖水平也产生良好影响。

Hargroue's method was ued to study the effects of nitrogen fenilizer forms, applyingdepth, and the combination of N fertilizer with P fertilizer application on N loss by volatilizationfrom a Loessial Soil. The results obtained show that different forms of N fertilizers had differentvolatilization rates. Ammonium bicarbonate was the largest in ammonia volatilization followed byammonium nitrate, ammonium chloride and ammonium sulphate. The placement of fertilizershad great influence on volatilization with N loss being reduced by 80.3% and 92.7%, respec-tively, when fertilizers were placed at 5 cm and 10 cm as compared with surface application.Ammonium loss from ammonium bicarbonate seemed to have no relationship with soil moisturewhile the ammonia loss from ammonium sulphate was decreased with soil moisture increase:when soil moisture increased from 13% to 19%, the correlation coefficient between the per-centage of ammonium loss from ammonium sulphate and soil moisture was -0.9685; when soilmoisture was more than 19%,the volatilized Percentage tended to be stable. The combination ofapplying N fertilizer with superphosphate seemed to have a certain effect on protecting ammoniavolatilization for ammonium bicarbonate, but there was no such effect for ammonium sulphate.

以红油土作供试土壤,采用Hargroue法,在室内对氮肥品种,土壤湿度,施肥深度,氮磷配合对氮素挥发的影响进行了研究。试验表明,不同氮肥品种的氨挥发率不同。挥发率最大的是碳酸氢铵,次为硝酸铵,氯化铵和硫酸铵。施肥深度对氨挥发有影响。深施5cm,10cm比表施时挥发分别减少80.3%,92.7%。碳酸氢铵中氨的挥发率似乎与土壤湿度无关;而硫酸铵中的氨挥发率随土壤湿度增加而降低:当土壤湿度从13%递增至19%时,硫酸铵中氨的挥发率与土壤湿度间的相关系数为-0.9685;土壤湿度再增高时,挥发率趋于稳定。过磷酸钙和氮肥混合对防止碳酸氢铵中氨的挥发损失似乎有一定效果,而对硫酸铵则无这种作用。

he morphological characteristics and distribution of component elements in corrosion layers of platform alloy steels were analysed by EPMA. The experimental results show that the different morphology as well as concentration and combination of alloy elements have a certain effect on the average corrosion rate,especially the local corrosive behaviour.Component elements,such as Mn,Cr,Cu,Ni,are richer in the inner corrosion layers,which makes them to be denser and more tightly stuck with steel substrate, thus preventing effectively the ions which cause corrosion, such as Cl-, S2-, OH-, Mg2+ and Ca2+ from diffusing towards substrate surface, reducing the corrosion rate.

利用电子探讨微束分析仪(EPMA)分析了平台合金钢腐蚀锈层的形貌特征及组成元素的分布。实验结果表明,不同的形貌特征以及不同含量的合金元素及其组合对平均腐蚀速度,尤其对局部腐蚀行为有一定的影响。组成元素如Mn,Cr,Cu和Ni在内锈层内富集,使内锈层更致密且与基体的附着性好,有效地阻止引起腐蚀的离子如Cl-,S2-,OH-,Mg2+和Ca2+等向基体表面扩散,从而减低了腐蚀速度。
