  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. Through the experimentation for the physical performance of cfpb masonry under local compression, the author has observed the deformation and failure of cfpbm. based on the mathematical statistics and regression analysis of the experimental data, the author derived a feasible and common formula for counting the cfpbm ' s local compression strength regarding the different local compression locations, analyzed stress distribution of local bearing masonry under beams end, and provided the calculating formula on effective supporting length of beam end in brick masonry. as the results of experiments demonstrate, owing to the cfpb ' s own holes " system, the beneficial effects, the bounding effect of surrounding masonry and the spread effect of force, have not developed completely

    試驗結果分析表明：由於多孔磚自身的孔洞結構，砌體內部的圍箍作用和力的擴散作用未得到充分發揮，局壓強度雖較軸心受壓強度有所提高，但仍低於同情況下實心磚的局壓強度；當有上部荷載作用時，對砌體局壓有利的懸臂卸荷作用和內拱卸荷作用均不明顯，因此在推導梁端局壓強度計算公式時，未考慮此可能存在的有利影響，計算偏安全；局壓強度提高系數公式除採用規范公式（二項式）的表達式，還用對數式進行了回歸推導，得到了一個較為普遍的公式；論文還對梁端局壓的梁端有效支承長度計算公式進行了回歸推導。
  3. This article presents a mathematical calculation model of kinematic parameters for the unusual shape beam pumping unit by analyzing its geometry relationship and kinematic characteristics

    異形游梁式抽油機的游梁后臂有效長度隨曲柄轉角而變化，故無法利用常規游梁式抽油機的解析方法來計算其運動參數。
  4. Even if experimenters bounce the beams to and fro to increase the effective length of an interferometer ' s arms to more than 100 kilometres, the expected difference in length between the two beams ' paths still amounts to less than a hundred - millionth of the diameter of a hydrogen atom

    盡管已經讓激光束反復反射來使激光干涉管臂的有效長度增加到超過了100公里，但在光路路程之內，兩束光波長差仍小於氫原子直徑的一億分之一。
  5. The simulation data of the flexible projecting beam with different crack flaw is different. so we can build bp neutral - work to identify the position and the length of the crack in the flexible projecting beam by the simulation data. the input vector of bp neutral - work is the simulation data becomes, the training object is the position and the length of the mapping crack

    Bp神經網路是一種多層的前饋型人工神經網路，可實現從輸入到輸出的任意非線性映射，所以選取bp神經網路可以有效地實現從觀測信號到裂縫所處位置以及裂縫長度的非先行映射，以達到對柔性懸臂樑上裂縫缺陷的智能診斷。
