We also study characteristic index and its determination of complex flocculant, put forward the new concept of total basification degree and present the determined method of B〓.In this paper, the author studied and improved on the Ferron Timed Complex Colorimetry, put forward the determination principle and determined method of the improved Ferron Timed Complex Colorimetry, and determined successfully the iron and aluminum hydrolysis-polymerized species of FMA complex flocculation at the same time.

研究了复合絮凝剂的特性指标及其分析测定方法、复合絮凝剂的絮凝特性评价方法，提出了总碱化度作为复合絮凝剂特性指标的新概念，并给出了分析测定方法；研究改进了Ferron逐时配合比色法，提出了复合体系中铁铝水解聚合形态同时测定的测定原理及方法，成功地将其用于FMA中铁铝水解聚合形态的同时测定。

One focus has steel wall clock, aluminum shell wall clock, alarm clock, iron, aluminum extrusion and other metal bell, but also the production of plastic clock, wood clock, leather clock.

其中重点有铁壳挂钟、铝壳挂钟、铁闹钟、铝挤压等金属钟，也有生产塑胶钟、木头钟、皮钟。

The flocculent experiments results showed that the comprehensive performance of PAFS was superior to that of PAS and PFS.

絮凝对比实验结果表明：PAFS综合性能优于聚合硫酸铁和聚合硫酸铝，具有铁盐絮凝剂沉降速度快、矾花大、铝系絮凝剂褪色效果好的优点。

During the period when aluminium demand surged and iron was in short supply,aggregate iron facility utilisation reached 80%of capacity.The explosion and closure of Gramercy in Louisiana in mid 1997,removing 800ktpa of iron production had a similar effect with world iron facility utilisation reaching approximately 77%,mostly via plants in China and Eastern Europe increasing production.

在对铝的需求剧增和铁的需求供不应求的时候，对铁生产设施的总利用率达到铁产量的80%。1997年年中路易斯安娜州GRAMERCY铁厂的爆炸和关闭，年度80万吨铁产量的转移，就产生了同样的影响，致使世界铁生产设施的利用率约达到77%，而大多数都是通过中国和东欧的铁厂增加产量实现的。

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

Iron trichloride or aluminium sulfate was used as a precipitating agent to precipitate sodium humic acid .

用三氯化铁或硫酸铝作沉淀剂，沉淀腐植酸钠，实验发现当腐植酸钠与三氯化铁或硫酸铝的质量比分别为 1∶ 0 。6 4和 1∶ 0 。6 0时，沉淀效果最好。

ANTICOR is the system which generates Cu-Fe ion or Cu-Al compound to protect internal surface of sea-water cooling pips from adhesion and growth of marine organisms by Cu-ion and protect copper alloys in condenser by forming Fe-ion or Al3 protective films as well.

ANTICOR 系统用来向海水中输送铜－铁离子或铜－铝离子。铜离子用来抑制海生物的生长并杀死海生物。铁/铝离子形成絮状物粘在冷却片及管壁上，使冷却片及管内壁免受腐蚀。

With the same Fe and Mn content, the primary iron phase in the hypoeutectic alloys is obviously less than that in the eutectic alloys, and α iron phase will form a kind of thin dendrite structure in α-Al dendrite crystal and will have strengthen effect.

在同样的铁锰含量下，亚共晶铝矽合金中的初生铁相明显比共晶合金要少，且α铁相在α铝树枝晶中会形成一种细密的树枝晶结构，可以作为基体的强化相。

In order to match the requirements of water treatment engineering, considerable attention was paid to develop composite inorganic polymer flocculants during recent years, which are represented by polyaluminum silicate chloride, polysilicate ferrite and polysilicate ferric aluminum.

受水处理工程需要的牵引，以聚硅氯化铝、聚硅酸铁及聚硅酸铁铝为代表的三大类新型复合无机高分子絮凝剂的开发研制及应用研究近年来受到格外的关注，取得了不少新成果。

Take the sodium silicate,the ferric chloride and the aluminum chloride prepared the high stability as the raw material research to polysilicate aluminum ferrite chloride.

以水玻璃，氯化铁和氯化铝为原料研究制备了高稳定性聚硅酸氯化铁铝。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
