Lead zirconium titanate (PZT) films (Zr/Ti=45:55) with a high dielectric constant are prepared successfully on the low-resistance Si substrate in sol-gel dip-coating process with PT film used as the buffer layer.
      
The solid acids were prepared by mounting H2SO4 on TiO2 · nH2O and Zr(OH)4, respectively, followed by calcining at 823K.
      
To deal with this contradictory situation, insolvable zirconium tricarboxybutylphosphonate (Zr(PBTC)) powder was employed to make a composite with SPEEK polymer in an attempt to improve temperature tolerance of the membranes.
      
SPEEK/Zr(PBTC) composite membranes were obtained by casting a homogeneous mixture of Zr(PBTC) and SPEEK in N,N-dimethylacetamide on a glass plate and then evaporating the solvent at 60°C.
      
Results showed significant improvement not only in temperature tolerance, but also in methanol resistance of the SPEEK/Zr(PBTC) composite membranes.

The present paper describes a high vacuum gauge expansion calibration system with a selective getter pump such as Zr-Al getter pump or titanium sublimation pump. With Ti-pump a stable base pressure of 2×10~(-7) Torr in the system was maintained for long duration. The rate of rise of pressure is almost equal to zero. By using Helium as test gas, the calibrations of ionization gauges were carried out within the range from 10~(-3) to 10~(-6) Torr and showed a good reproducibility. Calibration within the range...

The present paper describes a high vacuum gauge expansion calibration system with a selective getter pump such as Zr-Al getter pump or titanium sublimation pump. With Ti-pump a stable base pressure of 2×10~(-7) Torr in the system was maintained for long duration. The rate of rise of pressure is almost equal to zero. By using Helium as test gas, the calibrations of ionization gauges were carried out within the range from 10~(-3) to 10~(-6) Torr and showed a good reproducibility. Calibration within the range from 10~(-4) to 10~(-6) Torr can be easily realized with this small and simple system. It is possible to provide a low price system and simple method for the calibration of very high vacuum gauges. From the experiments with Helium, the sensitivity of gauge DL-2 was found to be of 4.2±0.2 Torr~(-1) in the range from 10~(-3) to 10~(-6) Torr, while the sensitivity of a BA gauge to be of 3.3±0.3 Torr~(-1) in the range from 10~(-5) to 10~(-6) Torr. Both gauges have a linear relation between the ion currents and pressures.

本文提出了一种带选择性吸气泵的膨胀法高真空规校准系统。用锆铝泵或钛球升华泵可长时间使密封系统平衡在较低的本底压强(用钛升华泵可稳定在2×10~(-7)托),系统的升压率近于零,并可在1分钟内达到稳定。用氦气作试验气体,在10~(-3)~10~(-6)托范围内进行校准,重复性良好。文中提出一种反馈式的二级膨胀原理,可以在很简单的小系统上实现10~(-4)~10~(-6)托的校准,为高真空规的校准提供了廉价和简易的方法。实验证明,在氦气氛下,DL-2规在10~(-3)~10~(-6)托的压强范围内的灵敏度为4.1±0.2托~(-1)。BA规在10~(-5)~10~(-6)托范围内的灵敏度为3.3±0.3托~(-1)。二种规的离子流与压强均有很好的线性关系。

Some characteritics of the gas released during activated and reactivated period,ionized type Zirconium-Aluminium getter pump analyzing with a quadrupole mass-spectrometer,are described in the paper.And for the changes partial pressure an analysis of mass-spectrum are made in absorbed H_2 and CH_4.It has been indicated that because CH_4 through a catalysis of heated W-filament decomposed as C and H_2;Carbon.is absorbed on the surface of W-filament and its heat diffusion can enter into the interior of W-filament.H_2 is immedidately absorbed by Zr-Al getter.Then,a critical temperature measured for CH_4 decomposed is about 1700℃. However,electron impact with CH_4 would result in the additional decomposition and ionization, then CH_4 could be contributed to the absorption.The experiments have shown that,under W-filament temperature becoming 2063℃,when ionized current is 57 mA,pumping speed of Zr-Al getter pump for CH_4 is some 475ml/s,and specific speed is 16.8ml/s·cm~2.
