Using high-shrinkage acrylic tow with boiling water shrinkage 29% and regular acrylic tow as raw materials,the high-shrinkage acrylic bulky top was produced via stretch-breaking technology on a Seydel-679 stretch breaking machine.

Through study on the filtration of cellulose acetate dope, an equal-effect filtration mathematic model was proposed to carry out fine filtration of the spinning dope, reducing the ends-out ratio to less than 0.

This paper introduces the cigarette-ping-en-mouth scrap in tow bar recovery process and equipment.

The application of microbeam in the research on radiation-induced bystander effects;

Running and improving of the computer control system for the CAS-LIBB microbeam;

Image Processing of Cells for the ASIPP Microbeam;

The micro-beam irradiation system,which focuses the beam down to micron order and precisely delivers a predefined number of ions to a predefined spot of micron order,is a powerful tool for radio-biology,radio-biomedicine and micromachining.

Single event upset maps and cross-section curves obtained from numerial simulation show excellent agreement with broad beam cross section curves and micro-beam upset images for 2 kbit hardened SRAM.
