The instantaneous temperature and unsteady heat flux on the piston crown, piston groove, and land are measured and analyzed. The major conclusions of this work include: (i) the instantaneous temperature and the heat flux on the piston are depended on injection angle. penetration distance of the injected flame, and the combustion chamber shape: (ii) especially.<br/> the instantaneous temperature of the top-ring groove and land are changed similar to the' instantaneous temperature of the piston crown.<br/>
The instantaneous wan temperature and heat flux of the Piston crown, ring groove and land are measured and analyzed It was found that (i) the instantaneous wall temperature of the valve pocket, in the piston crown, is higher than that of the center of the crown and the edge of the crown is lowest; (ii) the instantaneous temperature of the top-ring groove and land are changed simi1ar to that of the piston crown, which are influenced by the behaivar of the piston ring; (iii) the distributions of the heat flux are not coincided with the wall surface temperature, which are depended on the f1ame distance, combustion condition, behavior of the piston ring and the state of cooling, etc
The behaviors and distribution of wall temperature and heat flux on the cylinder head in the diesel engine, have been analyzed by using thin film instantaneous temperature probe. The main results are as following. ( i ) Instantaneous temperature on the cylinder head was affected by the direction of injected flame, amount of injected flame, the distance from the injection hole, combustion chamber shape, and flow characteristics (ii) Heat flux was transferred from the cylinder gas to the cylinder wall during largely expansion stroke and (iii) Heat flux distribution is shown different trend comparing to the temperature distribution.<br/>
The instantaneous surface temperature and unsteady heat flux on the cylinder head are measured and analyzed in order to obtain the basic data for the design at the combustion chamber of DOHC engine. The main results are as follows; i) The highest wall temperature is shown at vicinity of the exhaust valve bridge and the temperature of the exhaust valve bridge is continuously increased in the exhaust stroke. ii) The wall temperature at the exhaust valve head is about twice as high as that of the intake valve head. iii) The distribution of the heat flux has different tendency to that of the wall temperature and the heat flux of the exhaust valve bridge has a small value comparatively.<br/>
A 29 year old gravida 3, para 3 developed a study right lower quadrant pain after an uneventful home delivery. She underwent exploratory laparotomy and was found to have right ovarian vein thrombo- phlebitis. By palpation the thrombosis extended from the infundibulopelvic ligament cephalad for a distance of 8 to 9 cm. Bilateral adnexae, appendix and left ovarian vein appeared normal. The appendix was removed incidentaly. The patient did well postoperatively. She was given a course of potassium penicilline G and responded well. The patient made an uneventful recovery. She was discharged on the seventh postoperative day. There were no further sign of recurrent thrombophebitis during the post operative period, nor have there been ant t date.
