  1. In this paper, high heat penetration into a moving particulate bed is described mathematically with a comprehensive heat and mass transfer model. the distribution of gas velocity and pressure, the temperature field of gas and solid in the moving particulate bed are examined for different conditions. the results show that thermal penetration into the moving packed - bed particles by fluid flow in porous media is high only in the position near the gas entrance. the thermal penetration thickness tends to increase with the fluid flow velocity and decrease with the particle moving velocity. in the region of thermal penetration, the porosity of solid bed has significant effect on gas field and pressure loss. it is feasible to reduce the gas pressure loss by a larger width / height packed bed in design and operation. the correspondence between thermal infection depth and particle bed height would be helpful to keep high oapacity of reactor and reduce the cost of operation

    針對移動顆粒床中物料層內的高溫氣體滲流傳熱現象，考慮滲流與傳熱的相互作用，採用局部非熱平衡假設建立了多孔介質滲流傳熱物理數學模型並進行了數值計算.研究了不同情況下床內填充多孔介質中的流速、氣固溫度和床層壓力損失.計算結果表明，高溫熱氣對移動床顆粒料層的熱滲透主要發生在滲流入口端區域，增大入口滲流速度以及減小床層物料下移速度將導致物料溫度沿床高慢速下降，熱滲透深度擴大，熱滲透作用區域內的物料溫度水平提高.在熱滲透作用區域，孔隙率對流場和壓力損失有很大的影響.研究結果對于移動顆粒床反應器的設計與運行具有一定的參考作用
  2. The english understand by " marine risks " only risks incident to transport by sea, such as collision, stranding, fire, penetration of sea water into the holds of the ships, etc. in other words, under " all marine risks " recoverable loss will only be confined to those arising from perils of the sea and maritime accidents only

    英國人對「海洋運輸貨物險」只理解為海運中的意外風險，諸如船舶碰撞、擱淺、起火、海水侵入船艙等，換句話說，投保「一切海洋運輸貨物險」 ，其損失的賠償只限於因海上災難和海運意外事故所引起的損失。
  3. The lamp shade adopts pyrex with good light penetration and less penetration loss

    玻璃罩材料為耐熱玻璃，透光性能好，透射損失小。
  4. The most benefit was at right - angles impact with a gradual loss of benefit at higher obliquity ' s, dropping to zero at about 55 degrees obliquity, and actually improving the penetration ability of the shell by making ricochet more difficult at a higher obliquity

    這種效果在垂直擊中時最好，隨著入射角的增大而逐漸減弱，達到55度時效果消失，角度更大時則因為不容易製造跳彈，反而會加大彈頭的穿甲能力。
  5. Building penetration loss
