A assay method of immobilized resin was set up by testing the particle size and strength of resin, immobilizing, and testing stabilization of the immobilized enzyme, and some problems of resin in application in recent three years' resin screening work were summarized.

This paper firstly studied the bonding mechanism of the photosensitive resin blade,and then introduced the effective measures to improve the quality for photosensitive resin blade by means of the metal-coated diamond abrasive and studied the change of bonding ability of the blade compared with conventional abrasive.

Diamond abrasives(4～8μm girt size)are bonded quickly by photosensitive resin and then exposed under 300～500 nm wavelength ultraviolet ray to fabricate fixed abrasive plate.

Radical, cationic and hybrid photocurable resins used for stereolithography(SL) are introduced.

A series of photocurable resins used for SL are prepared.

The principle on stereolithography,laser source,photocuring resin and photo-initiator were reviewed.

The photocuring resin for Laser Rapid Prototyping & Manufacture was prepared,the shrinkage reasons of photocuring resin was analyzed,and the effect of the photocuring resin shrinkage on parts curl distortion was studied.

In recent years, the resin curemeter has been improved into fully-automatic controlling Model LHX-Ⅱ, and used to study the cure of thermosetting resin/montmorillonite nanocomposites, PMMA/montmorillonite nanocomposites and interpenetrating polymer networks.
