  1. The main purpose of this paper is to study crack growth rate of a class of nonlinear viscoelastic materials under the condition of constant load and small - strain. in this paper : the new test program is raised by referencing the existing test programs and by our trial and error ; in the new test program, facilities involved in the nonlinear viscoelastic crack tests are relatively few, the test process is relatively simple and the data obtained from the experiments are credible. on this basic, the calculation of j integral of nonlinear viscoelastic double cantilever beams specimens and the parameter of fracture work of corresponding nonlinear viscoelasticity are derived

    具體成果包括： 1 、證實了雙懸臂梁試件用於非線性粘彈性裂紋擴展實驗研究的優點：雙懸臂梁試件在實驗中能觀測到的擴展過程持續時間比較長，在計算j積分時，計算方法簡單； 2 、得到了改性聚丙烯材料用於非線性粘彈性裂紋擴展實驗的兩種有效的試件構形和相應的試件尺寸；採用不斷改善夾具的方法使得加載穩定； 3 、經過連續四個多月的時間得到了一組有用的實驗數據； 4 、得到了裂紋長度與時間的關系、裂紋擴展速度與時間的關系、裂紋擴展速度與裂紋長度的關系。
  2. By a lot of trial and error, a new - type lightweight fireproofing board is developed. the test results indicate this production has obvious characteristics such as high temperature resistant, moistproofing, low distortion, and fireproofing limitation of 3h. its safety and toxicity has been examined according to relative national criterion and standard and the results show that no deleterious and poisonous gas is produced after combustion

    經過反復多次試驗、篩選，研製出的隧道防火板質輕，具有一定的柔韌性，便於施工;耐溫、耐潮濕;變形小;耐火極限達3h ;安全毒性方面，參照室內空氣質量檢測標準等規范進行了測試，測試結果為:產品不釋放有害氣體，屬環保型材料;按照國家相關的材料規范檢測其毒性，檢測結果表明，產品在燃燒后不產生有毒有害氣體。
