Wfi in bulk is obtained from water that complies with the regulation on water intended for human consumption laid down by the competent authority, or from purified water, by distillation in an apparatus of which the parts in contact with the water are of neutral glass, quartz or suitable metal and which is fitted with an effective device to prevent the entrainment of droplets
注射用水通過符合官方標準的飲用水制備，或者通過純化水蒸餾制備，蒸餾設備接觸水的材質是中性玻璃、石英或合適的金屬，裝有有效預防液滴夾帶的設備。 -
It is comprised of a sensor head ( a quadrangular pyramid tip, a base, four quartz crystal plates ) and a network analyzer and an apparatus to apply three - axis force. according to mechanics, four plates of the quadrangular pyramid tip correspondingly receive four one - dimension forces when applying a three - axis force to the sensor head. because quartz crystal has a force - frequency effect, namely, resonance frequency change of the quartz crystal is in direct proportion to one - dimension forces applying to it, four certain resonance frequency changes of the four quartz crystal plates are corresponding to a three - axis force
當傳感頭受三軸力作用時，根據力學的分析可以確定三軸力與四角錐體四個面上單向力之間的對應關系，用分別貼在四角錐體四個面上的四片壓電石英晶體作為壓敏元件，由於石英晶體的力頻效應（即石英晶體在受到應力作用時，它的諧振頻率與應力大小成正比） ，從而最終確定了四片石英晶體的諧振頻率改變量與傳感頭上所受三軸力大小和方向之間的對應關系。 -
In the laminar flow regime, a analytical mathematical model is obtained by analyzing the film flowing in the wavy wall tube. in the turbulent flow regime, mathematical model almost ca n ' t be obtained directly because the turbulent flow in wavy wall tube is very complex, the model is obtained by quoting some results which are theorized by other studiers. in the part of experimental study, the flow form in the wavy wall tube is observed by transparent quartz glass wavy wall tube apparatus, the evaporation experiments are carried out in a 3 meters steel wavy wall tube, using glucose as the medium, heat transfer is invested, the heat transfer correlations of wavy wall tube evaporator are obtained
數學模型的建立過程中，對于液膜層流流動，直接對波形管內的降落液膜進行理論分析，得出液膜層流流動下數學模型的解析式；對于液膜湍流流動，由於湍流流動的復雜性，再加上所採用的波形管對湍流流動的影響，直接對降落液膜進行理論分析建立數學模型是極其復雜的，通過採用以前一些研究者得到的理論分析與實驗結果，並引入與波形管的形狀特徵參數有關的修正系數k ，建立液膜在湍流流動下的數學模型。
