Not directly Health drink, but also for Zuotang, cooking, food more fragrant, pure health system out of ice; From the use of water barrels of water, such as water inconvenience, not outsiders water, not only to protect the security and privacy of home, and avoid the secondary contamination; cleared encrustation, bathing not only skin feeling Shuanghua and showers, nozzle no longer block; wash out feeling fluffy soft clothing, colours more brilliant; bathroom facilities no longer difficult to clean up the White saturate and Xiuban; In the absence of encrustation not only to guarantee an independent heating or heat boiler or Bigualu safe operation and high thermal efficiency, saving energy.

答：不仅仅可以直接生喝，而且用于做汤、做饭，饭菜更香，制出的冰块纯净卫生；免去了使用桶装水订水、等水的不便，不用外人送水，不仅保护了家居的安全和隐私，而且避免了二次污染；清除了水碱，洗澡不仅皮肤感觉爽滑，而且花洒、喷头再也不堵了；洗出的衣物感觉蓬松柔软，颜色更亮丽；卫浴设施再也没有难以清理的白渍和锈斑；由于没有了水碱不仅能保证独立供暖或洗浴用锅炉或壁挂炉安全运行，而且热效率高，节省能源等。问：选择桶装水还是纯水机？

At the latter consolidation stage, it was assumed that the water flow only depended on water pressure and was not influenced by the air. Then the independent continuity equation of water was set up to solve variation of water pressure with time. Besides, the water and air were regarded as mixed fluid, and the continuity equation of mixed fluid was set up.

在其后的固结过程中，假定水的流出仅仅取决于水压力，不受气的影响，单独建立水的连续性方程，解水压力随时间的变化；又将水和气看成混合的可压缩流体，建立混合流体的连续性，解混合流体压力随时间的变化。

On the stage, our country's water resource hasn't have the qualifications to push whole marketing, still must hold the main body of public water rights. However, considering the water resource's sustainable utilization and taking marketing system of water resource as an assistance to raise the utilization efficiency of water resource. Genially speaking, the government must distribute the water which is related tightly to our dairy life and ecology.
