The aconite alkaloid in the waste fluid, resulted from steeping Chinese medicine aconite, was used to prevent pests. Tested with the method of Acid and Alkali Titration, the total alkaloid content of aconitic steep was 68.32mg/L.

利用中药材附子孢制过程产生的大量废液中的乌头类生物碱进行害虫防治研究，用酸碱滴定法测定附子浸渍液总生物碱含量为68.32mg/L。

METHODS: The concentration of ozone that was transmitted by ozone generator at different time was determined by using iodine titrimetric method. According to the bactericidal assay of quantitative vehicle, the bacteria on the ozonized vehicles and unozonized vehicles was washed, 50μl eluant was seeded on the TSA plates. The TSA plates were put into the anaerobiotic incubator (90% N2, 10% CO2, 37℃). After 24 to 48 hours, the CFU on the plate was counted.

用碘滴定法测定打开臭氧发生器不同机组及不同时间时的臭氧浓度，按载体定量杀菌试验，将经臭氧作用的载体与相同环境下未经臭氧作用的载体上的细菌洗下，各取洗脱液50μl，接种于TSA平板并置厌氧箱(90%N2， 10%CO2， 37℃)培养24~48h后，进行活菌菌落计数。

When hydrochloric acid was added into saccharin sodium solution,chemical reaction happened,whose product was glucide,which cannot be dissolved in water,however,it can be dissolved by ethyl acetate,therefore glucide can be extracted from other components,then can be determined by titration with sodium hydroxide.

利用糖精钠与盐酸反应生成不溶于水而溶于乙酸乙酯的物质，将其萃取出来，然后再利用氢氧化钠对其进行滴定分析，采用二分试差法准确测定了某镀光亮镍添加剂中糖精钠及某镀光亮镍液中糖精钠的含量，分别为88。

Results indicated that semidried mei preserved by reused brine or regenerated salt have higher values in acid, soluble solids, and salt contents than those prepared from fresh salt. However, there is no significant difference in sensory evaluation. These results implied that the reuse of waste brine is feasible.

研究结果显示以废液再腌渍的梅胚在可滴定酸含量、可溶性固形物含量、盐度等方面均较高，但官能品评方面则无明显差异，因此将废盐液重复使用於梅胚腌渍的构想初步可行，且再生盐亦可於二次腌渍时利用。
