对散居小学生的膳食调查,除了原始数据来源困难,更主要是需计算的数据庞大,因而工作量很大,手工运算有一定困难。微电脑的使用则提供了处理数据的最好手段。我们用BASIC语言编写了膳食调查处理系统,以《食物成分表》中334种常见食物的十二种营养成分为基本数据,并将其分为二十类。对膳食调查中的原始数据进行了归纳、统计、运算,从而解决了手工运算速度慢、易出错等问题,使运算速度大大提高。
The dietary survey of diathesis primary students, in addition to the difficulties in originating the data and the more important data to be calculated, is a heavy workload and has some handicaps. The use of microcomputers provides the best way to process data. We used the BASIC language to prepare a dietary survey system that uses the twelve nutrients of the 334 common foods in the Food Ingredient List as the basic data and divides them into twenty categories. The raw data in the dietary survey were summarized, counted and calculated, thus solving the problems of slow manual operation and error-prone operation, which greatly increased the operation speed.
