1. The runoff has the catabatic effect to acidification of water quality.

2. Results:137 patients had an obvious catabatic symptom after operation. None was recrudesced . The cure rate achieved 100%.

3. Results: The cure rate was 85.2%(23 127), the catabatic rate was 14.8%(4 127), and the total efficiency rate was 100%. 12 cases were followed up, and lesion faded away and hadn't recurred in 2 years.

4. Conclusion: The time of fusion, the fusion rate and catabatic grade of clinical results are no significant difference between two groups.

5. Objective We explore the clinic usage according to observing the change of lung-functions and eosinophil (EOS) between the acute-outbreak period and catabatic period of asthma sufferers.

6. Objective It is to observe the changes of lung function and eosinophil(EOS) in patients with bronchia asthma in acute-outbreak period and catabatic period, so to explore its clinical significance.

7. It was proven to be of good performances of catabatic corrosion and scale prevention in practice.

8. Put out the manage method more fit to noise catabatic.
