borderline condition

The main conclusions are: groundwater flux of NO 3 N was 30.06% of total terrestrial flux; groundwater flux of nutrients is an important borderline condition for the marine environmental evaluation.

结果表明，1999年5月下旬地下水向海洋输送的NO3N占整个陆源输入量的30.06%，说明地下水向海洋的营养盐输送量是海洋环境评估的重要边界条件。

Investigation on Anti-wear Effects of Borderline Lubrication under Different Condition of Tribological Pairs

基于不同摩擦副条件下的边界润滑抗磨效果研究

The hydrodynamic model of surface water flow movement possess a better simulation precision but because its calculation is relatively complex and the disposal of borderline condition is comparatively difficulty, study on this model is a little deficient and further research is needed.

地面水流运动的全水流动力学模型具有更高的模拟精度，但是由于其计算比较复杂，边界条件处理起来比较困难，在这方面的研究与应用还比较欠缺，有待于以后对其作进一步研究。
