人们买西瓜常用敲听、手感法判断瓜的生熟,有关书上也有所介绍。但按这种“理论”选购西瓜是不很可靠的。有些人用尖刀在瓜七划一立体三角口来检查西瓜的生熟,由此倒可得到一些启发。为了既不伤瓜又能判断瓜的生熟,可以用味敏元件装在医用注射器管内制成味敏探头吸出瓜汁,将生熟不同的甜、酸度转换成电信号经适当处理后显示出来,既可靠又科学。研制这样的西瓜生熟探测仪之关键是味敏还是某种成份的敏感器件问题,别的技术都较成熟。建议研制这类信号器(不仅是西瓜方面)。这对买瓜的、卖瓜的和种瓜的都有好处。
Common people to buy watermelon knock, feel melon judge melon, the book also introduced. But according to this “theory ” to buy watermelon is not very reliable. Some people with a sharp knife in the melon seven draw a three-dimensional triangular mouth to check the raw watermelon, which can be down to some inspiration. In order not to hurt the melon but also determine the melon’s raw and cooked, you can use flavor-sensitive components installed in the medical syringe tube made taste sensitive probe suck melon juice, the raw and cooked different sweet, acidity into electrical signals after appropriate treatment showed , Both reliable and scientific. The key to developing such a watermelon raw and ripe fruit detector is a sensitive component of flavor sensitive components, other technologies are more mature. Proposed to develop such annunciator (not only watermelon). This is good for buying melons, for selling melons and for melons.
