光面

We could put the stone surface under the sunlight lamp or sun, granite and marble , stone products observe its reflecting surface, then could see clearly these kind of concave and strip, if it is because of the mineral, we could ignore it, but if it is because of the bad polish, then had better to avoid to purchase this kind of stone.

我们把加工好的石材表面对着太阳光或日光灯，观察反光面就可以清楚发现如图所示的各种凹坑和条痕，对于那些无规则的细小凹坑可能是由石材组成矿物的一些自身缺陷造成的，可以不去考虑，而如果在石材的表面发现一些有规律的条痕，则是由于加工质量较差造成的，选购时应尽量避免这样的石材。

In a market economy, enterprises must attach great importance to technological progress, and to take practical actions to achieve universal adoption of concrete admixtures; scored with ribbed steel bars of variable cross-section to replace the glossy steel as the production of prestressed Concrete products and reinforced concrete products, reinforced; concrete mixing system to the early realization of microcomputer control; by roll welding machine to replace the hand-made steel skeleton of banding; centrifugal molding, product testing, as well as a phase of water pressure of the pressurized pipe to achieve the conservation process of automatic control ; vigorously promote energy conservation, etc.

在市场经济条件下，企业必须高度重视技术进步，并采取可行的措施，尽快实现普遍采用混凝土外加剂；用带肋刻痕的变截面钢筋取代光面钢筋作为生产预应力混凝土制品和钢筋混凝土制品的配筋；混凝土搅拌系统要尽早实现微机控制；用滚焊机取代手工绑扎制作钢筋骨架；离心成型、产品水压检验以及一阶段制管的加压养护过程实现自动控制；大力推广节能养护窑等等。

According to the climatic features of the Yangtze River Basin and the area south of it develops a complex heat pump unit. Its condenser is composed of finned tubes and smooth tubes in series, characterising both air cooling and evaporative cooling modes.

根据长江流域及其以南地区气候特征，研究开发了复合式热泵机组，机组的冷凝器由翅片管组和光面管组串联组成，兼具风冷冷却和蒸发冷却方式特点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
