- We can make the normal reaction between two surfaces in contact twice as large by doubling the mass carried by one surface. 我们可以通过使一个接触面的质量加倍而达到两接触表面的作用力力增大一倍的效果。
- The intersectionof two surfaces in three dimensions. 在立方体中的两个面的相交。
- The intersection of two surfaces in three dimensions. 在立方体中的两个面的相交.
- two surfaces in contact 接触着的两个表面
- Roller or ball bearings have gradually edged out the earlier types of bearings in which the surfaces in contact move by sliding. 滚柱或滚珠轴承已逐渐代替那种接触表面靠滑动运动的早期型号的轴承。
- Sliding friction is independent of the area of surface in contact. 滑动摩擦力于表面接触的面积无关。
- Have the children been in contact with disease? 孩子们同这种疾病有过接触吗？
- When handling raw poultry or raw poultry products, persons involved in food preparation should wash their hands thoroughly and clean and disinfect surfaces in contact with the poultry products. 在处理生家禽或家禽产品后,参与制备食品的人应将手彻底洗净并对接触过家禽产品的表面进行消毒。
- I came in contact with her by telephone. 我和她通过电话联络。
- An unintentional or faulty transfer of wet ink from a printed sheet to another surface in contact with it. 平版印刷出于疏忽或失误而把一已印出纸张上未干的墨迹转印到与它相接纸张的表面
- Are you in contact with him now? 你现在与他有联系吗?
- This shows that sliding friction is proportional to the reaction between the surface in contact. 这说明滑动摩擦力与接触表面的作用力成正比。
- The two substances are now in contact (with each other), and a chemical reaction is occurring. 现在这两种物质(互相)接触产生了化学反应。
- Two surfaces rubbing together generate heat. 两个表面互相摩擦会产生热。

- Having surfaces in the same plane; even. 水平的，同高的在同一平面上的；平坦的
- This machine has a highly polished large diameter drying cylinder which burnishes the surface in contact to give a high glaze; the underside of the paper is rough. MG paper is often used for posters, wrappings, etc. 这机器有一个大直径，表面极度光滑的烘缸。纸面和它接触后，被磨平光滑；纸底则粗糙。光面纸常用作海报，包装纸等。
- Press hard on the two surfaces,to make them stick together. 用力挤压这两面，使它们紧紧粘在一起。
- The better performance of GF coating is ascribed to its lower dissolution rate and more resistant oxidation film formed on the coating surface in contact with well-aerated seawater. GF镀层的耐蚀性明显提高，潮差区的充气条件又促进了镀层的钝化，表现出较为优异的耐腐蚀性能；
