1. During the extracting process, four main factors, namely solid:liquid ratio, immersing time, extraction temperature and extraction time were studied by using single factor analysis method.

2. It is found that air liquid ratio and slurry concentration are crucial to spraying character.

3. Meanwhile, the gas - liquid ratio for foam drilling or gas - filled underbalanced drilling in pressure formations is analyzed.

4. The rheologic parameters are mainly influenced by gas liquid ratio and base mud properties.

5. The accurate value of gas and liquid ratio can be determined using laser confocal scanning microscope combined 3D reconstruction software.

6. The effects of liquid ratio, time, temperature and catalyst on the liquefaction were investigated.

7. RESULTS:The amount of adsorbed iodine onto chitosan was related to the concentration of iodine, the immersing time and the solid to liquid ratio.

8. The test results indicate that operation at high flue gas velocity improves the mass transfer effectively, increases SO 2 removal efficiency significantly and decreases gas liquid ratio.

9. An review of the recent progress of biocatalysis systems with high solid liquid ratio was presented.

10. Then we can calculate the accurate value of gas and liquid ratio depending the gas bubble and entire hydrocarbon volume values.

11. In this paper, the process and the influencing factors of microwave dewaxing were studied, including powder to liquid ratio of slurry, quantity of back-up coatings, power of microwave,[Sentencedict.com] etc.

12. The optimal reaction conditions were as follows; the main factors which affect the decolouring ratio were acid con centration, solid - liquid ratio , temperature and activation time.

13. Analyses parameter have inclined angle, pipe diameter size, gas liquid ratio and friction factor and so on.
