同軸電纜測試：如果電纜是好的，主測試器bnc燈和遠程終端燈同時發亮，若不亮則該電纜是壞的 -
The main research is below : ( 1 ) the influence to intensity and rigid with corner angle ( 60, 75 and 90 degree ) of crack and the board axes ( 2 ) do a fem stress / strain and crack growth simulation analysis when the corner angle of crack and the board axes is 60 degree ( 3 ) do a intensity resume analysis for the structure which is repaired with a titanium patch in a mechanical way when the corner angle of crack and the board axes is 60 degree through simulation analysis for three failure criterion, we have : ( 1 ) in 60, damage extend quickly with damage analysis in hashin criterion ; it is slower for analysis in maximum stress or hashin - rotem criterion. ( 2 ) in special term ( physical condition incision, shape or maximum load ) the compression strength of the stiffened plate will decline 45 % ~ 50 % under compression loads
通過採用三個不同損傷判據的數值模擬模擬，得到如下結論： （ 1 ）在60時，用hashin判據進行的損傷分析，損傷擴展較快；最大應力及hashin - rotem判據進行的損傷分析，損傷擴展基本相當，且較慢； （ 2 ）在所給加筋板的物理條件、切口大小及形狀、最大載荷等一定的條件下，該加筋板在壓縮載荷作用下，其壓縮強度下降了45 50 ； （ 3 ）在本文提及到的機械連接修理方法以及載荷條件下，修理后的結構強度恢復能夠滿足戰時要求。 -
The repair effect was compared with various type of repair parameters such as patch thickness young ' s modulus and thickness young ' s modulus of adhesive layer. in the chapter iv, a thermalstatic mechanical loading analysis of the repair problem was made. for the single side repair, the patch material having the maximum mismatch in the coefficient of thermal expansion with that of the crack aluminum plate provides the better damage tolerance capability for single - side crack in the panel
模擬計算表明：粘膠模量增大， j積分值降低，修補效果與粘膠模量有關；隨著粘膠厚度的增大，修補模型的j積分值略有增大后再逐步減小，應合理選擇粘膠的厚度，盡量避免選擇j積分較大值時的粘膠厚度；隨著補片厚度的增加，修補模型的j積分值逐漸增大，到達一定量后又開始減小，因此補片的厚度需要合理選擇。 -
We suggested one kind of planar metamaterials with periodic patterns tiled by two resonant components, which consist of triangular and pentagonal patch arrays and a metallic ground plate interconnected by via arrays together
摘要設計了一種由兩種不同諧振單元套構而成並按周期排列組成的平面型異向性材料，該平面結構由三角形和五邊型的金屬貼片周期平鋪構成上表面，並通過金屬化導孔與下底板的金屬底板連接。
