沉淀物的

First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.

首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；其次，HF与铝硅酸盐的化学反应不是简单的一次反应，其副产物氟硅酸和氟铝化物还可与铝硅酸盐发生二次反应和三次反应，形成一系列不溶性的沉淀物，对储层造成严重伤害；第三，高温情况下酸液对井下管柱及工具腐蚀性很强，对缓蚀剂性能要求高。

Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

在明矾与氨水沉淀物经过滤后再额外添加不同硫酸铵的比例，1200℃ 1hr煅烧后，发现添加硫酸铵比例在1以上，其型态亦为蠕虫状纤维，当以1500℃ 5hr煅烧，蠕虫状纤维型态粒子亦变为又大又胖，其粒子尺寸长度约为 2 μm 宽度约为 500 nm；且将煅烧1200℃ 1hr测其比表面积值，会随著硫酸铵的添加量增加，粉体的表面积会增加且粉体变细，添加硫酸铵比例为 4 者所得粉体粒径最小，从比表面积所得结果估计约 150 nm 。

The sediments in this photo curve near the ends of chert pods.

这沉淀物在这幅图片的曲线近似冷凝物的黑矽石的扁豆形矿体。

The necks of the bottles are then frozen and the corks removed to disgorge the accumulated sediments.

然后将瓶的颈部冻结并拔去瓶口的软木塞除去聚集的沉淀物。

On the contrary, the setting time of the composite cement slurry delayed greatly and their fluidity were increased significantly after blended with lead nitrate.

与此相反，掺Pb(上标 2+)后复合水泥净浆的凝结时间明显延长，胶砂的流动度明显增大，早期强度也明显降低，分析认为这主要是水化过程中形成了含Pb沉淀物，它们包裹着水泥颗粒，形成致密的不途水层而使水泥水化受阻所致。

Jiuzhaigou has 108 "haizi" of varying sizes and shapes, but of invariant limpidity to the bottom of the lakes. Some of the lakes are hidden in the valleys, and others inlay the virgin forests.

晴日天，湖底的水藻和沉淀物在阳光的照射下，发射出一圈圈色彩斑斓的光环，所以又被人们叫做"五花海"。

Muddiness created by stirring up sediment or having foreign particles suspended .

因沉淀物被搅起来或有外部的悬浮而造成的不的状态。

" Casein, or ""cheese painting,"" is a medium in which pigments are temper ed with the gluey curd of cheese or milk precipitate."

酪蛋白颜料画的颜料是把颜料与奶酪的胶质凝乳，或牛奶沉淀物混合。。

" Casein, or ""cheese painting,"" is a medium in which pigment s are tempered with the gluey curd of cheese or milk precipitate."

酪蛋白颜料画的颜料是把颜料与奶酪的胶质凝乳，或牛奶沉淀物混合。。

When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile.

当雨真正下来后，它又可能将大量的土壤冲刷至青尼罗河和埃及，沿途也带上了来自白尼罗河的沉淀物。

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。
