查询词典 emittance

Venetian blind radiators can be replace by the variable emittance thermal suite in thermal control system of spacecraft, and it is one of key technologies for microsatellite.

引 言目前，在许多航天器的热控系统中，采用机械式热控百叶窗，控制航天器与空间环境的热交换，以实现航天器热控目标。

Those ions will perform stable oscillation nearby the beam orbit while their mass is larger than a critical mass. The accumulation of trapped ions nearby the beam orbit, interacting with beam, can cause the tune shift of beam, blowup of beam emittance, increase of local vacuum pressure, and can even lead to the occurrence of beam instability.

这些被俘获的离子在束流轨道附近的积累并和束流的相互作用，会引起束流振荡频率的漂移和展宽、束流发射度的增加、局部真空度的恶化等各种负效应，有时甚至会导致束流不稳定的发生，从而影响储存环的正常工作，在这种情况下采用离子清洗方法将离子清洗掉对保证储存环的长期、稳定的运行是必要的。

Limits to the minimum spot size, imposed by space-charge effect, emittance and spherical and chromatic aberrations of the lens, are investigated by means of a five-order radial trajectory equation, the K~V envelope equation and an analytical method.

理论上，利用推导的非线性轨迹方程、K-V包络方程及解析方法研究了空间电荷效应、发射度、透镜球面像差和色散像差对最小焦斑直径的限制并对聚焦实验布局和参数进行了优化选择。

The purpose of this thesis is tomeasure the beam emittance on TIF.

本论文是为完成TTF上束流发射度的自动测量而做的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
