The filling process naturally causes an increase in oxygen content, including the remaining oxygen after vacuum filling (particularly for the bottle itself has not been purged or purged inadequately). This oxygen in the filling machine liquid tank and air content in the bottle neck enters the capper.

灌装过程造成的含氧量增加，包括抽真空后（特别是未经抽真空或只经一次抽真空的瓶子）瓶中的部分残留氧、灌装机贮液缸中的氧及灌装完成并卸压后瓶子离开灌装机进入压盖机的过程中瓶颈空气的含量。

Let them go on not supplying weapons. Nature abhors a vacuum, Putin told reporters in Caracas.

让他们继续不提供武器好了，自然界不喜欢真空，普京在加拉加斯告诉记者说。

The company has a complete system of vacuum sintering carbide seven lines, annual production capacity of 100 tons.

To ensure smelt is successful, 5 steel study furnace of 2 vacuum induction controls carbolic element component strictly.

为保证冶金胜利，五钢探讨二所真空感觉炉严励掌控炭因素成分。

Reducing afterblowing and using the carburant with low nitrogen content are important measure. The kinetics of nitrogen removal from liquid steel under vacuum with reaction between carbon and oxygen was studied on the multi-function induction furnace. The following conclusions were obtained by experiments: The nitrogen removal was obtained by the nitrogen transfer through the liquid steel diffusion layer at 67Pa and 110Pa pressure, and by the gas-liquid surface chemical reaction at 2000P.

结果表明：真空度对脱氮机理有影响，67Pa～110Pa时脱氮为一级反应，2000Pa时脱氮为二级反应，1340Pa时为混合控制；即使在。1％的条件下，碳氧反应亦可显著提高脱氮速度常数促进深脱氮，在RH内通过加强碳氧反应来提高脱氮率理论上是可行的；当钢液内存在内生或外来固态粒子时，有利于钢液中CO及N〓气泡的形成及排除，这时气泡内p〓≈0，有可能使钢液中氮含量低干与系统真空度平衡的氮含量。
