最近召开的全国储粮机械通风技术经济交流会议提出:必须进一步开展对粮食机械通风技术的试验研究工作,以不断完善这项技术、提高这一工作的水平。开展试验研究,首先必须选定一些经济技术指标以比较各种通风装置的性能,这是进行可行性分析必不可少的过程。在实际工作中,选定哪些经济技术指标进行比较,则是关系到试验研究结果可信程度的关键。根据我们几年来开展这方面对比试验的情况,就上述问题提几点不成熟的看法:
The recently held conference on economic exchange of grain storage machinery ventilation technology put forward: It is necessary to further carry out experimental research on the ventilation technology of grain machinery in order to continuously improve this technology and enhance the level of this work. To carry out experimental studies, we must first select some economic and technical indicators to compare the performance of various ventilation devices, which is an essential process for feasibility analysis. In actual work, the selection of which economic and technical indicators are compared is the key to the credibility of the experimental research results. According to the comparative experiments we have conducted in these areas over the past few years, I have put forward some immature opinions on the above issues:
