| 1. | Balanced depth of compression zone 界限受压区高度 |
| 2. | Depth of compression zone 受压区高度32 |
| 3. | The gas drainage technique with short boreholes in stress reduced area for mining face with outburst hazard 高突工作面卸压区浅孔抽放技术 |
| 4. | Research on technology of draining methane off shallow borholes in a stress - relaxation area of working face 工作面卸压区浅孔瓦斯抽放技术研究 |
| 5. | When the ductility of steel bar is bad , the ductility of section will be bigger with the improvement of the ductility of steel bar 钢筋延性较好,则构件截面延性随截面相对受压区高度的减小而增大;钢筋延性较差,则构件截面延性由钢筋延性控制。 |
| 6. | According to simulated results , we can get the range of side pressure relief at the mining face , at the upper coal or the lower coal under the peculiar condition 根据模拟结果得出:特定开采条件下,上部或下部不同煤层采煤工作面侧向却压区范围。 |
| 7. | 9 pieces of rc test beams were fabricated , the fbg sensors and strain gauges were mounted in the tensile steel , compress concrete and cfrp of the tested beams 制备9根rc试验梁,将fbg传感器与电阻应变片同时预置于实验梁内(受拉钢筋、压区混凝土及碳纤维复合材料中) 。 |
| 8. | Then limiting load is decreased . ( 6 ) horizontal load can increase the coefficients of the modulation of moment when value of is little while decrease it when is large ( 6 )在中支座截面相对受压区高度较小时,有水平荷载的框架其弯矩调幅系数要大于只有竖向荷载的框架。 |
| 9. | The following conclusions are reached . ( 1 ) the relative height compressive zone of section or the axial force is bigger , the rotational capacity of the section is weaker 得出了以下主要结论: ( 1 )截面相对受压区高度、截面所受轴力显著地影响预应力框架梁截面的延性。 |
| 10. | This model transacts and calculates pull and press section of reinforcement concrete by different methods : the reinforcing steel bar element model is adopted at pull section and the reinforced concrete enblock model is adopted at press section 该模型用不同方法处理计算钢筋混凝土拉区和压区:拉区钢筋采用杆件单元模型,压区钢筋混凝土则采用整体式模型。 |
