The precipitate in liquor is a common problem in distilleries which have to tackle with and the frequent causations are as follows: floccule induced by three kinds of higher fatty acid ethyl ester and microthermal storage and filtration could prevent it; white flakes of precipitate induced by containers for liquor storage such as aluminous pots which produced alumina and mare nectaris which dissolved into coating and then caused precipitate; precipitate induced by undergrade additives and CP grade or AR grade additives could prevent it; precipitate induced by water quality and strict management of water quality could prevent it; precipitate induced by packing materials and the solution was acid water washing for new bottles and liquor filling after the inner of the bottles was completely dry.

白酒产生混浊沉淀是一普遍问题，常见的有絮状沉淀，主要由3种高级脂肪酸乙酯引起，可于低温贮存过滤；白色片状沉淀，由贮酒容器引起，铝罐贮酒，会产生氧化铝溶入沉淀，最好不用铝罐贮酒；酒海贮酒会溶入涂料，造成沉淀，酒海贮酒不宜过久；由劣质添加剂引起，最好使用CP级或AR级添加剂；水质引起，对水处理应严加管理；包装材料引起，新瓶应用酸性水洗，且须控干水后再灌酒。

When the precipitate is not yet coarsened as shorter in rupture life, the precipitation hardening effect may be intensified by the increasing of precipitate, so that the high temperature strength may be raised by the increase of W content, while the precipitate may coarsen markedly and the precipitation hardening effect may reduce on heating for sufficient long time.

在持久寿命较短时，析出相来不及粗化，析出量的增加造成了析出强化效果的加强，即钨量的增加提高了高温强度；而当长时间加热后，析出相发生了明显的粗化，降低了析出强化效果。

The preparation process includes the following steps: dissolving activator and RE oxide in the molar ratio of 0.01-0.02 in concentrated nitric acid and heating to dry, dissolving the obtain RE nitrate in deionized water to obtain solution of RE nitrate; dissolving soluble tungstate and surfactant in deionized water to obtain tungstate solution; mixing the RE nitrate solution and the tungstate solution through stirring to reaction for 25-60 min to obtain white precipitate; hydrothermal reaction of the precipitate in a reaction kettle at 100-260 deg.c for 24-72 hr; centrifugally separating, washing and drying to obtain the product.

浓硝酸的加入量保证稀土氧化物溶解就可以，过量的硝酸可以加热除去；将可溶性钨酸盐和表面活性剂溶解于去离子水中，得到钨酸盐溶液，表面活剂性的加入量为反应原料重量的0-30wt％；将稀土硝酸盐溶液加入到钨酸盐溶液中搅拌，发生沉淀反应，磁力搅拌时间为25-60分钟，得到白色沉淀；将含有沉淀物的溶液作为前驱物加入到反应釜中，发生水热反应，反应温度为100-260℃，反应时间为24～72小时；离心分离，洗涤，干燥，即得所需产物。

precipitate：沉淀物

最後的数字只可是0或5.溶液浓度计算准确至四位小数.- 质化分析 (Qualitative analysis) 的实验不涉及任何数量化结果,那麼便应详述实验中的可见观察结果 (visible observation),例如有否沉淀物 (precipitate) 及其颜色,有否气体放出及其颜色及测试其身份的结果,

precipitate：沉淀

水质当中所含钙离子与镁离子,会在槽液之中形成沉淀(Precipitate)物质,也会影响贯孔制程中所用的其他槽液. 所以槽液所须的水质,最好使用去离子水,至少也要使用经过处理之后的软水(Soft Water),以免影响槽液的操作进行.检查一下钻孔制程所用的钻针是否锐利,

precipitate：沈淀物

将上清液与沈淀物(precipitate)分开,分析步骤如下:2.0 c.c. 2.0 c.c. 加入上述试剂可将沈淀物溶解. Vortex混匀并放置常温10分钟. 若有不沈淀之杂质,用离心法将之弃除. 每一样品要在335-390 nm 波长扫描 (以空白管做为blank),

precipitate：促进

我喜欢"促进"(precipitate)这个词. 它本来是个化学技术词汇,用来描述从混合溶液中促进某一组分的结晶过程. 但结晶并不是立即产生,通常需要有一个晶核. 晶核有时是同一结晶体的一个小小的分子,在溶液中注入一点纯净物质将导致链式反应,

crystalline precipitate：晶形沉淀

crystalline phenol 结晶酚 | crystalline precipitate 晶形沉淀 | crystalline size 晶粒大小
