1. This paper addresses this by comparing three types of water supply, piped water, tube wells and shallow wells.

2. He pointed the water tube of pointing the part.

3. When a waste heat vertical water tube boiler recovers waste heat, the fluid in the boiler will be changed from liquid into gas.

4. The circular cooling water tube of BF is characterized by the large system, wide-diameter tube, long lines and complicated layout.

5. Observation data of water tube tiltmeter with type FSQ of Tanchang station from 1990 to 1998 are analysed.

6. The RFM-S capacitor comprises the core, enclosure, cooling water tube and connecting terminal supported by sheath.

7. The model DSQ water tube tiltmeter is a digital seismic precursory instrument developed in the 9th 5-year-plan.

8. The design of infiltration ditch contains the obtaining water tube, anti-filter layer, well, pump house and other accessory building.

9. Non-synchronous temperature variation at two end reservoirs of water tube tiltmeter is one of the most important interference sources.

10. Objective To assess the effect of steel water tube on drinking water in China.
