查询词典 Meridian Gate

Ion gate is one of the important parts in an ion mobility spectrometer.The main function of the ion gate is to control the ions to fly into the drift tube in pulse mode.

在仪器的关键部件――离子门，研制了一种成本低，制作工艺简单的离子门，该离子门相邻金属丝间距为0.75mm，同时考查了离子门处电压特性对迁移谱的影响。

The main factors determined IMS resolutions are the initial ion gate pulse width and diffusion in the drift tube. We conclude the homogeneity of the electric field in the drift tube through analyzing the relation between resolution and ion gate pulse width and drift tube temperature. It is still concluded that inhomogeneity of the electric field has much influence on IMS resolution, which is generally ignored previously.

IMS分辨率最主要的决定因素是离子门脉冲的开门时间和离子在迁移管内的扩散效应，根据在不同离子门开门时间和不同温度下所作的分辨率关系曲线，我们推断出了迁移管内电场的均匀情况，并且得出在一般的IMS工作条件下，迁移管内电场的不均匀对分辨率也有很大的影响，这在以前人们讨论IMS的分辨率时通常被忽略，并没有引起足够的重视。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.
