粉末

However,TEM and SEM images reveal that the gel process can reduce the size of agglomerate significantly.

陶瓷的表面形貌图表明，粉末中的团聚体越小，陶瓷的微观结构越均匀，表面越平整。

The activating and sintering characteristics of hydroxyapatite agglomerate treated by shock wave were studied .

研究了经冲击波处理的羟基磷灰石粉末团聚体的活性及其烧结性能。

The results offer the condition that these plants of Ajuga could be distinguished by size and ornamentation of exhymenine.

结果表明，同属三种植物的形态特征相似，可通过叶形及花期是否具基生叶，花萼的形态，花冠颜色以及茎的生长方式和植株被毛情况等予以鉴别；通过对三种植物的花、根、茎、叶及全草粉末的组织构造观察，认为种间差异较小，可依据毛茸的分布及形态特征和茎的木化程度不同加以鉴别；对三者花粉粒进行了扫描电镜观察，发现其大小和外壁纹饰具有明显差异，为三者的鉴别提供了有力的依据，也为该属的分类及植物花粉形态研究提供了花粉形态学方面的资料。

The carbonaceous alcosol and the silica alcosol were prepared respectively by using aqua-mesophase and tetraethoxysilane as starting materials. Then the two alcosols were mixed and dried in open air and under supercritical fluid conditions to form binary carbonaceous-silica xerogel powders and aerogel powders respectively.

以正硅酸乙酯和炭质水性中间相为原料，分别制得了炭质醇溶胶和硅醇溶胶，将二者进行混合后再利用常压干燥法和超临界流体干燥法分别制备了二元炭质-二氧化硅干凝胶和气凝胶粉末。

Heat or sunlight converts it to the red phosphorus allotrope, a violet-red powder that does not phosphoresce or ignite spontaneously.

热或日光将其转化为「红磷」，一种紫罗兰红色的粉末，不会发出磷光也不会自燃。

The best condition I had was on the closing day of Alta, in April, we had one feet of fresh powder.

我有的最佳的情况在在关闭的天亚尔他，在4月，我们有新鲜的粉末的一英尺。

Having been in the alternative health care field for Contact Us Description Monographs include chemistry chemical structure Phentermine Hydrochloride is a white crystalline powder very soluble in water and alcohol.

曾在卫生保健领域的另类接触我们描述为专着包括化学结构化学是服用盐酸白色结晶粉末很溶于水和酒精。

Ultrafine γ-Al 2O 3 particles were prepared by thermal decomposition of ammonium alum .

铵明矾加热分解可制得超细γ－Al2O3粉末，进一步灼烧可制得α－Al2O3微粉。

Carbon can promote the forming of carbide of Fe3C mostly during the MA, while it seems that chromium makes amorphism easier.

机械合金化过程中，碳元素可以促进以Fe_3C为主的碳化物的析出，铬元素使粉末更趋向于非晶态转变，并使材料出现超顺磁现象。

The main contents in this thesis go as follows.The polymorphic transition process of 5'-GMPNa2 from amorphism to crystal was investigated by in-situ monitoring technique and ex-situ monitoring technique. The transition mechanism was deduced to be solution mediated transition.

具体研究内容如下：利用聚焦光束反射测量仪、颗粒图像测量仪和X射线粉末衍射仪等测试手段对5'-鸟苷酸二钠由无定形体转化为晶体的过程进行了研究，推断出其过程机理为溶液过渡转化。

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。
