摘要： A GC-IMS system is disclosed in embodiments of the present invention. The system comprises a sample transfer device. The sample transfer device connects the gas chromatograph to the reaction region and, the sample from the gas chromatograph is transferred to the reaction region by the sample transfer device directly, instead of not through the ionization region. With the GC-IMS system, generation of sample molecular ion fragments can be avoided so that the spectrum is brevity and is easily identified; moreover, the application field of the GC-IMS system is extended to a range of analysis of organic macromolecule samples which have a high polarity, are difficult to volatilize, and are thermally instable. On the other hand, the GC-IMS system overcomes the defect of ion destruction due to neutralization reaction among positive and negative ions so as to evade the detection.

摘要： Human body back-scattering inspection systems and methods are disclosed. In the invention, X-rays modulated by the flying-spot forming unit having spirally distributed flying-spots have a distribution having alternating peaks and valleys on the irradiated surface. In this way, scanning starting times can be precisely controlled to cause two devices to have scanning starting times that are different by a half of a cycle. That is, the beams outputted from one device are at maximum when the beams outputted from the other device are at minimum. In other words, even if the ray source of one device emits rays, it will not significantly affect imaging result of the other device. In such way, the two devices may emit rays and perform scanning at the same time, and thus the total scanning time is reduced.
摘要翻译：公开了人体背散射检查系统和方法。在本发明中，由具有螺旋状分布的飞点的飞点形成单元调制的X射线具有在照射面上具有交替的峰和谷的分布。以这种方式，可以精确地控制扫描开始时间，以使两个装置的扫描开始时间不同于周期的一半。也就是说，当从另一个装置输出的光束为最小时，从一个装置输出的光束是最大的。换句话说，即使一个设备的射线源发射光线，也不会显着影响其他设备的成像结果。以这种方式，两个装置可以发射光线并同时进行扫描，因此总扫描时间减少。

摘要： An inspection system included a ray source to emit a ray, a detector to receive the ray, a detection region for placing an object under inspection, and a moving device to move the ray source and the detector around the detection region. Conventional scanning blind zones such as both sides of a human body, both sides of arms and both sides of legs can be completely eliminated. In addition, it is not necessary for a human body under inspection to carry out an action such as turning around to change his or her posture. Therefore, ineffective time can be minimized in the entire detection and a passing rate of persons under inspection can be improved. Furthermore, an inspected person's mental feeling of being controlled due to change of posture can be greatly improved, and his or her mental discomfort and conflicted moods can be reduced.
