1998年4月件日，以工程院院士侯芙生为主任的8人专家组通过现场勘查、审定，最后得出结论性鉴定：聚合物干燥机改造、延长喷丝板使用寿命两项成果在国内同类厂家中有较高的推广价值．睛给生产的物耗、能耗、产量、质量、环保等指标都优于设计保证值，在国内处于领先地位，达到? On April 1998, an expert group of eight academicians led by Hou Fusheng, an academician of the Chinese Academy of Engineering, passed an on-site investigation and examination, and finally reached a conclusion: the results of the modification of the polymer dryer and the extension of the service life of the spinneret were similar in the domestic market. There is a higher promotion value. The material consumption, energy consumption, output, quality, and environmental protection of the eye are all better than the design guarantee value.
