摘　　要：在实验室装置上对医疗器材灭菌用包装纸进行了细菌气溶胶滤效测定。结果证明,选测的二种纸张(2层)对空气中细菌的阻留效果可达97％以上。纱布或棉布(2层)的阻留效果仅为8～52％,远较前者为差。The bacterial aerosol penetrability of two kinds of wrapping papers was determined in laboratory. The experiment was carried out on a device constructed specially for determination of filtration efficacy of filter material. When the air flowed through the paper tested (double layered) with a filter area of 47 mm in diameter at a rate of 28 L/min, more than 97% of bacteria could be retained, while double layered gauze and cotton cloth could only retain 8～15% under the same conditions. The result suggests that it is possible to keep the medical supplies wrapped by the paper tested in sterile state for a long time.
