A specific grade or degree of pulverization, as of coffee beans

磨细的程度：在磨细中的特定等级，如咖啡豆的

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。

The steps of the method including boiling whole, slices or pieces of the raw edible product for a time sufficient to partially cook the starch and soften the tissue of the edible product; comminuting the cooked product; and drying the comminuted product.

本方法的步骤包括将整的生可食制品、生可食制品的切片或碎片煮制足够的时间以便使淀粉部分熟化并且使可食制品的组织软化；将熟化的制品磨细并且将磨细的制品干燥。

Beginning of the main products have wide Superhard grinding straight shank end mill, grinding superhard wide keyway milling cutter straight shank, straight shank superhard grinding the whole fine-tooth milling cutter, full grinding superhard coating straight shank cutter, Super 1 / 2 shank twist drill, straight shank twist drill three categories of products.

开始的主要产品有全磨制超硬直柄立铣刀、全磨制超硬直柄键槽铣刀、全磨制超硬直柄细齿立铣刀、全磨制超硬直柄涂层立铣刀、超硬1/2柄麻花钻、直柄麻花钻等三大类产品。

A processing of fly ash ground by vibrating-mill and efficient-mill was studied. The results of dry and wet grinding under isothermal and non-isothermal conditions with efficient-mill and vubrating-mill were compared.

把粉煤灰磨细后用作水泥的掺合料，在抗压强度上可以获得较为满意的效果，寻找高效低廉的磨细途径是正在积极探索的问题之一[1，2]。

Avoiding the shortage of bleeding and viscosity,and improving pumpability can be actualized by using double-mixture with ground slag and fly ash.

本文介绍了磨细矿渣在商品混凝土中的试验和应用情况，采用磨细矿渣、粉煤灰双掺技术可克服混凝土泌水和粘稠性缺点，提高可泵性。

And the thin degree of mineral is very thin. If want to achieve the rich purpose to collect the iron through rub the tailing again to separate the silicon and irons from the ore, it is very difficulty and the cost is too expensive.

由于浮选后的精矿品位不高，尾矿产生量大，其铁品位在43%左右，且原矿磨矿细度已经很细，如果想通过尾矿再磨，分离矿石中的硅和铁，达到富集铁的目的，难度很大，且成本不合算。

With water in the middle of the roll at the ends of fine and coarse water roll in lathe smoothed into, because it is elastmer, shoulderpieces for loading, with fibrillation and pressure small, most of which there are different levels at the ends of the shape of the fine and coarse error in the Middle, where there is space so easy to play dirty.

着水辊两端不不细洋间不不细着水辊在车床上增工磨平进时，由于是弹性体，两端受力不小，洋间有颤抖并且不张力小，不小局部都活命着不同水平的两端不不细洋间不不细的轮廓差错，两端活命间隙从而便当起不净。

Durability tests of the specimen,including tests of abrasion resistance,infiltration resistance,frost resistance(routine frost and coupling with the frost and salt), shrinkage were done.

为了提高路面混凝土的耐久性，通过机理分析，将炼钢时的废渣磨细后，作为第6组分掺入水泥混凝土中，制作了高性能路面混凝土试件，并对掺磨细矿渣高性能路面混凝土试件进行了耐磨性、抗渗性、抗冻性(包括一般冻融和盐冻耦合)及收缩性的试验。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
