    本文從zroz相變增韌和微裂紋增韌兩種機制出發對實驗結果進行了深入研究和討論。
  8. Sem results showed that, microcrack induction ability of these materials was markness. in a word, the working performance, bond strength, elastic ratio, brittleness of structural adhesive modified by proper materials were improved, satisfied engineering requirement. its modifying technology was simple and convenience, has very high active extending sense and application value in structural adhesive modifying field

    採用適當的納米材料改性環氧樹脂結構膠的綜合性能優良，能滿足工程應用的要求，而且改性工藝簡單可行，在結構膠改性領域里有積極的推廣和應用價值。
  9. Abstract : a new process of modified treatment of diesel engine link was investigatea in this paper. it made the link get adaptable microstructure and hardness without microcrack

    文摘:提出了一套柴油機連桿調質處理的新工藝，使連桿在沒有顯微裂紋的情況下得到合適的顯微組織和硬度。
  10. The size of microalloyed carbides is very small and some is only 2 ~ 3nm. so microcrack extending can be restrained

    並且，由於微合金碳化物尺寸很小，可達2 3nm ，對于微裂紋擴展有一定的約束作用。
  11. And then a laminar structure was formed in the front of the crack tip. a microcrack might nucleate at the crack tip and propagate ahead perpendicular to the laminar structure

    首次發現純鎂裂尖變形以單系滑移為主，其斷裂過程是滑移減薄，形成層狀結構，然後裂紋垂直於層狀結構擴展。
  12. The result of sem - eds shows that the microcrack is on the surface of the wetted part, but not on the not wetted part. the crack is superficial and affects only thin outside layer, not penetrate aluminized layer

    掃描電鏡和能譜分析（ sem - eds ）的結果表明，樣品表面被液態鉛鋰合金所浸潤的部分出現微裂紋，而未浸潤部分沒有出現微裂紋。
  13. Double grid air counter ( dgac ) is a better useful nodestructive testing tool that was developed and researched in recent years and its advantage is real - time test by the emission of the low - energy electrons from the microcrack of the metal material

    雙柵極空氣計數管是近年來開展研製的一種無損檢測的有力工具，其特點是可根據金屬材料微裂紋處低能電子的發射實現實時檢測。
  14. The permeability behaviour of specimens ( concrete, mortar and paste ) with microcrack ( 0. 1 ~ 0. 35mm width ) is different from those without microcracks. water volume flowing across microcrack per hour will reduce with the increase of permeating time and the reducing is most significant in the first three weeks

    帶有裂縫試件水的滲透試驗表明：單位時間通過裂縫的滲透水量會隨著滲透時間增加而減小，在滲透實驗開始的三周內減小幅度最大，其後趨緩。
