0 a chemical element that is a soft, silver-white alkaline metal. Caesium reacts strongly with other chemicals and is used in photocells. -- 铯（金属元素，银白色，质软，化学性质活泼，用于制光电池）
It is found that the addition of as little as 1% of caesium profoundly alters the properties of the plasma.
Equations (3a)-(3f) express the law of mass action applied to the two ionization stages of noble gases and caesium.
Over the next 10 days, an area of about 1000# km, containing many villages and farms, was heavily contaminated with plutonium, caesium and radioactive iodine.
Those formed in mixtures of noble gases and caesium, in particular, are also of importance in different laboratory situations; for example, plasma etching and ion-beam etching.
The observed plasma formed from atomic hydrogen generated at a tungsten filament that heated a titanium dissociator and one of potassium, rubidium, caesium and their carbonates and nitrates.
Again, this is primarily ascribable to the variations in ne due to the presence of caesium, although the inclusion of electron-atom collisions provides a non-negligible contribution as well.
Three hundred and six samples of milk were analysed for both caesium 134 and caesium 137.
They are a means of ensuring that caesium does not come on to the market from young unfinished lambs.
