Gradual Transformation

Based on the overburden three caving feature, the deformation of mining rock process was devided and the criterion of gradual transformation of each stages deformation were given. Then , combined the thin-plate theory, the differential models were derived for rock deformation in level and similar to level bured condition. The boundary condition of each models and exchange condition between different models were put forward and the gradual mechanics model was set up.The subsidence model before roof collapse was solved by Navier double trigonometric series and the deflection surface expression of rock deformation was put forword. At last, the reliability and practicality of the models was verified by engineering examples.

Reduced Flow

1. Gravity-fed intravenous infusions were studied in patients by using continuous flow recording and a new resistance-measuring method. 2. A common, though preventable, cause of reduced flow was the gradual deformation of the plastic tubing under the regulator clamp. 3. In many cases there was some constriction of the cannulated vein and in a few this constriction was severe enough to seriously impair the infusion. The severity of the constriction varied periodically. 4. There was no evidence of trouble due to a generally raised pressure in the arm veins nor was clotting in the cannula a serious problem. 5. A simple test is described which may be found useful clinically for assessing the difficult infusion.
