均匀的细料结构的石材具有细腻的质感，为石材之佳品；粗粒及不等粒结构的石材其外观效果较差， 黄金麻机械力学性能也不均匀，质量稍差。另外，天然石材由于地质作用的影响常在其中产生一些细脉、微裂隙，石材最易沿这些部位发生破裂，应注意剔除。至于缺棱少角更是影响美观，选择时尤应注意量，即量石材的尺寸规格，以免影响拼接，或造成拼接后的图案、花纹、线条变形，影响装饰效果。
The stone with uniform fine material structure has fine texture, which is the best stone; the stone with coarse grain and unequal grain structure has poor appearance effect, uneven mechanical properties of gold and hemp, and slightly poor quality. In addition, due to the influence of geological process, the natural stone often produces some veinlets and micro cracks, and the stone is most likely to crack along these parts, so it should be removed. As for the lack of edges and corners, it also affects the beauty. When selecting, we should pay special attention to the quantity, that is, measure the size and specification of stone materials, so as not to affect the splicing, or cause the deformation of patterns, patterns and lines after splicing, and affect the decoration effect.
质量好的路边石内部致密均匀且无显微裂隙的石材，其敲击声清脆悦耳；相反，若石材内部存在显微裂隙或细脉或因风化导致颗粒间接触变松，则敲击声粗锈钢铸件 保定建筑设计 螺杆式启闭机 保定搬家 电缆挂钩 保定室内设计培训 冲压机哑。用简单的试验方法来检验石材质量好坏：通常在石材的背面滴上一小滴墨水，如墨水很快四处分散浸出，即表示石材内部颗粒较松或存在显微裂隙，石材质量不好；反之，若墨水滴在原处不动，则说明石材致密质地好。
For the stone with dense and uniform interior and no micro cracks, the knocking sound is clear and pleasant; on the contrary, if there are micro cracks or veinlets inside the stone or the contact between particles becomes loose due to weathering, the knocking sound is coarse and dumb. A simple test method is used to test the quality of stone: a small drop of ink is usually dropped on the back of the stone. If the ink is quickly dispersed and leached, it means that the internal particles of the stone are loose or there are micro cracks, and the quality of the stone is not good; otherwise, if the ink drops do not move in the original place, it means that the stone is dense and of good quality
