A common heating oxidation device(fig.1)is to place a silicon plate in a quartz crystal glass reaction chamber. In the reaction chamber, a electric resistant wire heating device heat up the chamber to a certain temperature(usually, the temperature is 900～1200℃. In a special condition, it can be descended to under 600℃). When oxygen or water vapour pass through the chamber(typical gas flow speed is 1cm/s). A chemical reaction is generated on surface of the silicon plate.

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.關鍵詞 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

The nozzle of the gasifier is simplified. The cold-flow field in the gasifier chamber is studied. The research shows that the chamber has recirculation along the whole length. The particles in the chamber perform a very good flowing characteristics even for the large particles of dp=150μm, and no abrupt change is observed. This is due to the operational pressure is high and the density of the gas is large there. The maximal reflux velocity of both phases, the reflux intensity, the concentrational distribution of particles, and the static pressure loss in the chamber are all related to following factors: the load of gasifier, the concentration of coal-water slurry, the diameter of the coal particle, the distribution ratio of oxygen in the two channels of the nozzle, and the angle of jet in nozzle.
