This paper discusses some issues in nested relational databases, which mainly include the e-valuation on two normal forms PNF and NNF, missing information and the conversion form flat rela-tional schema to nested relational schema.

Electron microscope scanning surface morphology and XRD analysis showed that inhibitor NNF reduce the increase in the oxygen, sulfur, to form a continuous dense FeS protection film, preventing corrosion.

电镜扫描表面形貌分析和XRD表明，缓蚀剂NNF使氧元素增加、硫元素减少，能形成连续致密的FeS保护膜，阻碍了腐蚀的发生。

For radar using purpose, The data algorithms for NNF and the adaptive a-P filtering and prediction based on "CV" model are studied emphatically.

根据实际雷达跟踪要求，对NNF数据关联算法和基于CV运动模型的自适应滤波与预测算法等作了重点研究。

The yield of winter wheat and summer maize were kept quiet low and steady when NNF was applied for more than 4 seasons.

连续四季以上不施氮使冬小麦和夏玉米产量分别稳定在1693～1807kg/hm2和4575～4782kg/hm2范围的较低水平。

Polarization curve testing found that the NNF is a hybrid inhibit, adsorption of membrane-type inhibitor.

极化曲线测试发现，缓蚀剂NNF是一种混合抑制吸附膜型缓蚀剂。

NNF for more than two seasons reduced both winter wheat and summer maize yield significantly.

连续二季和三季不施氮使冬小麦和夏玉米产量都大幅度减产；

Winter wheat yield was much reduced comparing with that of summer maize under NNF.

不施氮条件下，冬小麦的减产幅度大于夏玉米。
