You're going on a regimen that will really improve your health—not like that crash diet: You'll snarf down antioxidants; exercise moderately but consistently; balance fats, proteins, and carbs; and pay attention to the way you explain whatever happens to you.

你要采用一个将真正提高你的健康的养生之道--和"快速减肥节食法"不同，你将要吞下抗氧化剂，一贯性地进行适度锻炼，平衡脂肪还有碳水化合物，并且关注对任何发生在你身上的事情的解释方法。

Results Twain-80 can increase the solubility. The dimethylsulfoxide, the sorbic acid and acetic acid chlorine can strengthen its bacteriostasis effect. To choice suitable antiseptic temperature and control antiseptic time may enhance furacilin liquid preparation stability. On the contrary, it may reduce the stability when mixing the antioxidants agents such as the sodium hyposulfite and the sodium bisulfite.

结果 吐温-80可增溶；二甲基亚砜、山梨酸和醋酸氯己定可增强其抑菌效果；选择适宜灭菌温度、控制灭菌时间可提高呋喃西林液体制剂的稳定性；加入硫代硫酸钠和亚硫酸氢钠做抗氧化剂则使其稳定性降低。

Through lots of tests, the new technology of preparing the polymeric ferric aluminum silicate sulfate by using the waste-acid of Ti02-industriy and the coal fly ash has been designed. The highest Al-acid stripping rate can be achieved by the waste sulfate acid under boiling degree for 1. 5h when the mass ratio between NaCl and Coal Fly ash is 0. 05:1, as well as that between Coal Fly ash and Waste Acid ratio is 1:10. By means of the oxidation-polymerized reaction under 40-50*C and normal pressure, using NaNCkas catalyst and air as oxidation, the polymeric ferric aluminum sulfate can be obtained. The poly-silicic acid is polymerized with soluble glass in the optimum conditions of pH=5-6 and the concentration of Si02 is about 3%. The inorganic high molecule coagulant of PFASS is synthesized with the poly-silicic acid into the solution of polymeric ferric aluminum sulfate.

本论文通过大量的试验，研究开发出了用粉煤灰及钛白废酸制取聚合硫酸硅酸铁铝的新工艺，其最佳工艺条件为：于沸点温度，以NaCl为助溶剂(NaCl与粉煤灰质量比为0.05：1)，以钛白废酸浸取粉煤灰(固液比为1：10)中的铝1.5小时，最大浸取率可达40％；经过滤洗涤后，调节滤液pH至2.0左右，以NANO_2为催化剂(NaNO_2用量为滤液中FeSO_4·7H_2O量的3％)，空气为氧化剂，于40-50℃进行常压催化氧化反应，制取聚合硫酸铁铝，催化氧化时间为2小时；将工业水玻璃稀释至3％左右，调节其pH于5-6，室温下制备活性聚硅酸；将活性聚硅酸与聚合硫酸铁铝按照一定比例复合，经熟化，即制得新型无机高分子混凝剂PFASS。
