1. Fortunately, because they are diving birds, temporary submergence in rough weather is not going to trouble them.

2. Most emergence or submergence does not remain strictly vertical.

3. Submergence stress result in oxygen limitation in maize roots.

4. Submergence of BFP is a key procedure to exploit marginal oil and gas field economically.

4. try its best to gather and create good sentences.

5. Submergence and drought are major constraints to rice (Oryza sativa) production in rain-fed farmlands, both of which can occur sequentially during a single crop cycle.

6. Inadequate submergence can result in pre-rotation of the water in the wet-well, resulting in the formation of strong free-surface air core vortices and the entrance of air into the pump suction inlet.

7. Thus, once proper anti - vortexing submergence is established, the concern about motor overheating will frequently be eliminated.

8. Limit pump diameter and percentage of submergence are derived theoretically. Trial and error method is used to calculate the rational percentage of submergence and pump setting depth.

9. However, for little submergence the flow separates at aft - dome and a weak vortex forms in cavity.

10. The ranges of rational submergence depth and pump setting depth are presented for Fuyang reservoir of Xinli oilfield.

11. This is floated in the water being tested and assumes different levels of submergence depending on the salinity of the solution.

12. With different layout of inverted siphon pipe, requirements for inlet flow pattern and submergence are various.

13. Cold spring paddy soils are the low yielded soils with puddling soil layer formed under strongly reducing condition induced by persistent submergence.

14. The paper presented an experimental study of the critical submergence of pressure power intakes.

15. An ample water supply is probably the greatest advantage of soil submergence for irrigated rice.

16. It is widely used to test castable on porosity by submergence in physical property inspection.

17. A jet Pumps performances are characterized by its efficiency, cavitation and submergence from different aspects.

18. The discharge coefficient decreased as the relative degree of submergence increased at the submerged discharge.

19. In many cases it will be found that the minimum recommended submergence to prevent vortexing will be equal to, or greater than, the minimum submergence required to prevent overheating.

20. Analysising for inflow performance relationship, giving the design method of submergence depth and pump setting depth.

21. Some of the species are flooded and vanished during the flood season. Only some tall grasses survive with high tolerance of submergence. The dominant species belong to Gramineae and Cyperaceae.

22. Proper design and operation of submersible pump systems necessitates consideration of minimum submergence requirements.

23. The calculating results show that the circulating flow rates are increasing with the submergence ratio but reducing with the liquid-gas density ratio.

24. The academic society pondered, Do not have to let the year submergence in inexhaustible bustling about.

25. This paper analyses the source of uncertainty of porosity tested by submergence and evaluate the uncertainty.
