This approach underpins much of my research on energy and nutrient flux, and has involved both natural abundance and enriched isotope tracing techniques.
该方法巩固了对于我在能量和营养流的研究，并结合了自然丰度和浓缩同位素跟踪技法。

Decreasing the heat flux or outlet two-phase resistance, and increasing the system pressure or inlet single-phase resistance are useful to avoid the natural circulation flow instability.
