吸气剂

In the end. the application of the Zr-V-Fe getter in the electronic device, vacuum technology and scientific research are introduced.

同时，介绍了锆钒铁吸气剂在电子器件、真空技术和科学研究中的应用。

The bacteria culture was done for the endotracheal tube, the expiration and inspiration entrance of the anesthesia machine, and the soda lime in eighty general anesthesia patients. Results There are no bacteria growing in the new and the polluted new soda lime at the different stages.

对麻醉机的CO2吸收剂钠石灰进行不同时期细菌培养，菌株污染新的钠石灰进行菌落计数， 80例气管插管全身麻醉病人在手术麻醉结束前对病人的气管导管端、麻醉机的呼气端、吸气端、钠石灰行细菌培养。

The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.

结果表明：暴露于过大气的吸气剂表面覆盖着H2O、CO2及碳氢化合物等，Zr和V主要以氧化态存在；在吸气剂加热激活过程中，V的氧化物在200℃开始还原；激活过程导致表面近金属态Zr的富集以及部分金属碳化物的生成；随着温度的升高，H2O、CO2及碳氢化合物逐渐从吸气剂表面脱附，在200℃以上，主要脱附气体为H2，整个激活过程未发现O2；ZrO2还原为近金属态或金属态，主要是由于ZrO2中的O通过向吸气剂内部扩散而离开吸气剂表面所致。

The influence of particle size of Ti powder and sintering temperature on the sorption properties of Ti-Mo getters has been studied.

研究了Ti粉粒度及烧结温度对吸气剂性能的影响。

Three kinds of Ti-Mo getters were made using Ti powder with different particle sizes.

以3种不同粒度的活性Ti粉制备Ti-Mo吸气剂。

Introduces the characteristics and performance s of the non-evaporation getters NEGs St707 and St101 and some problems are proposed to deal with in their applications,based on relevant literatures and experience got from practice.

根据文献和实践经验，综述了非蒸散型吸气剂 St70 7和 St10 1的性能特点以及 NEG在实际应用中要注意的问

In the ultra high vacuum activation, reduction of the vanadium oxide started at a lower temperature (250℃ to 300℃), and the reduction of the titanium oxides started at a higher temperature(300℃).

当吸气剂置于高真空激活时，钒的氧化物在较低的温度(250℃~300℃)开始被还原，钦的氧化物在稍高于钒的温度(300℃)也开始被还原，400℃时表面已经有大量的金属钦的存在，而Zr的氧化物在(100℃~400℃)激活过程中，则没有明显的变化。
