In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了將壓電晶體諧振器用作定量測量質(zhì)量的裝置亚州毛片a片视频，并從理論上導(dǎo)出了頻率與質(zhì)量變化之間的關(guān)系式——Sauerbrey方程：ΔF=〓=-亚洲最大黄色网站免费。。黄页视频免费在线观看。

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

In range of 300℃～900℃, all the transition metal oxide catalysts could get high ammonia conversion, during the initial stages of the reaction, the SO〓 conversion is relatively low since the catalysts have not been sulfureted, but it increases gradually and attain constant with rising temperature and time continuance,〓 is better than other catalysts in reactivity and elemental sulfur selectivity; XRD indicates that, in the SO〓-SCR process, stable transition metal sulfide is generated which is very important to SO〓 reduction and transition metal sulfide probably is the active phase of catalyst, further the reduction of SO〓 by H〓 to H〓S is the limiting step of all process, then the activity is somewhat related to its lattice oxygen yet not so notable; XPS indicates that little sulfur on surface exists as S〓 in sulfate, showing that TiO〓 could restrain the generation of sulfate.
