x-bridge

基本解釋

Based on the coupled vibration theory, dynamical models and equations of motion were set up respectively to an X-style arch bridge and vehicles.
采用車橋耦合振動理論，分別建立了鐵路車輛和提籃拱橋的動力模型及其運(yùn)動方程。
Compare with the traditional concrete-filled tube arch bridge, the X-shaped arch bridge has the predominance on the stability in cross, the span and the bearing capacity and so on.
相對于傳統(tǒng)鋼管混凝土拱橋而言，提籃拱橋在縱、橫向穩(wěn)定性、橋梁跨度和承載能力等方面具有獨到的優(yōu)勢。
Furthermore, from the stability analysis of the X-type double ribs arch bridge, this paper show how changes inclined inward angle would affect the stability, and the optimum design is presented.
其次，從變寬度X型肋拱橋穩(wěn)定性分析出發(fā)，給出內(nèi)傾角度對穩(wěn)定的影響并特別提出了最優(yōu)角度。

If it senses that you've fixed your gaze on a specific location for more than a few seconds, a nose-bridge mounted HD camera will take a 50 x 50 pixel snapshot and compare it to its image database -- much like Google Goggles.
