retardance 中文意思是什麼

retardance 解釋
延遲性
  1. In this paper, we design a new film stack by use of multi - frequency design idea, which decrease the film thickness of high refraction layers greatly, and the damage threshold of it will be improved hopefully. and at the base of this film stack, by optimizing the film thickness of several outmost layers, we design the hr film at 45 incidence for 632. 8nm and 1315nm with 180 ? or 90 phase retardance at 1315nm

    隨著高功率coil輸出功率的進一步提高，傳統的設計膜系已逐漸不能滿足需要，為此我們利用倍頻的沒計思想，設計出了一種新的高反射膜系，與傳統的設計膜系相比，此膜系大大降低了高折射率層的厚度，使得膜系的損傷閩值有望得到極大提高。
  2. In order to control the polarization characteristics, the phase retardance mirror must be used. additionally, in order to suppress the reverse wave in ring resonator, the phase retardance mirror must also be used to preserve the polarization characteristics of the reflected reverse wave by suppressor. the conventional film stack ca n ' t satisfy the high power coil development requirement

    另外，通過對高功率coil用環行非穩腔內倒向波抑制的分析表明，為實現倒向波的抑制，倒向波被反饋到腔內正向波中的部分必須保持偏振狀態不變，否則，起不到倒向波抑制的作用，這也需要用到高反射位相延遲鏡。
  3. Forests as an adjuster for ecological balance in mountain areas play important roles in soil and water conservation, runoff and silt retardance etc. especially, forests are regarded as " forest reservoir " due to their great hydrological regulation functions through canopy, undergrowth, litterfall and soil layers

    森林是山地生態平衡的重要調節器，特別是其水源涵養、理水保土、緩洪滯淤的功能對于山地面積大的福建省顯得極為重要。森林通過林冠層、林下植被層、枯枝落葉層以及土壤層發揮良好的涵養水源、保持水土、削峰滯洪等「森林水庫」的功能。
  4. Study of toughening flame retardance high impact polystyrene by sbs and poe

    蜜棗對流乾燥傳質特性的研究
  5. At last, the designed hr phase retardance films are produced by use of the e - beam evaporation equipment, then the phase retardance and the reflection of it are measured by lambda 900 spectrophotometer and the type of m - 2000ui ellipsometer. and the error of hr phase retardance film is analyzed

    在此膜系的基礎上，通過對最外面幾層薄膜厚度的優化設計，最終設計出了45入射、對632 . 8nm和1315nm雙波長高反，並在1315nm處有180和90位相延遲的高反射膜系。
  6. In this paper, the methods to enhance the flame retardance and thermal stability of epoxy resins by introducing the compounds containing silicon or phosphor elements to epoxy matrix were reviewed in details

    摘要介紹了在環氧樹脂中引入含硅組分來提高其耐熱性和韌性、引入含磷組分改性環氧樹脂提高其阻燃性方面的研究進展。
  7. Features : has good chemic stability, endure the erosion of common chemicals, possesses good air - tightness, fire retardance, water - tightness and grinding resistance

    具有良好的化學穩定性，能抗耐一般化學藥品的侵蝕。具有良好的氣密性、耐燃性、耐水性和耐磨性。
