    摘要: A multi-energy static security CT system comprises at least one N-stage image chain structure (5) and a baggage conveying belt (4) provided at an inner side at the bottom of the N-stage image chain structure (5). The N-stage image chain structure (5) and the baggage conveying belt (4) are fixed at a pre-configured positions by means of a machine frame (8). The N-stage image chain structures (5) are sequentially arranged in a forward direction of a baggage channel, and adjacent N-stage image chain structures (5) are offset relative to each other. By exposing radiation sources in the N-stage image chain structure (5) at different times, the static security CT system generates an image having a higher temporal resolution and more energy spectrum levels than an image generated by a spiral CT system. Also provided is an imaging method implemented by means of the static security CT system.

    摘要: A low attenuation single mode optical fiber includes a core layer and claddings. The core layer has the relative refractive index difference (RRID) Δ1 ranging from −0.1% to +0.1% and the radius R1 ranging from 4.0 μm to 6.0 μm. The claddings have three claddings layers surrounding the core layer. The RRID of the first cladding layer Δ2 ranges from −0.2% to −0.6%, and the radius R2 thereof ranges from 10 μm to 22 μm. The RRID of the second cladding layer Δ3 is less than Δ2. The RRID and radius of the first cladding layer and the RRID and radius of the second cladding layer satisfy the relationship of: V=(Δ2−Δ3)×(R3−R2), and the value of V ranges from 0.15% μm to 0.8% μm. The third cladding layer is all the layers that closely surround the second cladding layer, and the RRID of each layer is greater than Δ3.
