| 1. | Does the ability to map the unknown deserve less credit from society than the ability to retrace the known ? 预测未知的能力,难道不如追究已知的能力值得社会推重吗? |
| 2. | But french school did not hold in esteem the concept of world literature 但是, “世界文学”的概念并不被法国学派所推重。 |
| 3. | With the rapid development of aero science , it requires the aero engine ratio of traction to weight is higher and higher 随着航空科技的飞速发展,要求提供推重比越来越高的航空动力。 |
| 4. | The limited special edition of leehom s latest album . with one bonus 2004 calendar card and bonus vcd , featuring 4 mv 现推重装出击版,随碟附送2004琉球写真年历卡,及bonus vcd ,收录王力宏4首冠军主打mv |
| 5. | To seek theoretical support from history - on zhou zuren ' s high praise in the 1930 ' s for inspiration essays of school quot; gong an quot; of late ming dynasty 30年代周作人推重明末公安派性灵小品原因考察及其他 |
| 6. | The results showed that the thrust - weight ratio reached 1 . 04 for the launch weight 5400kg in the condition of specific impulse near 600s 结果表明:在发动机工作比冲接近600s的情况下,对于起飞质量为5400kg的飞行器而言,推重比为1 . 04左右。 |
| 7. | To optimize specific impulse to 700s or 800s , the thrust - weight ratio could be improved to 1 . 23 or 1 . 41 , it is enough to achieve the launch requirement for this vehicle 进一步将比冲优化至700s或800s ,可以将推重比提高至1 . 23或1 . 41 ,这样就完全能够保证发射任务的完成。 |
| 8. | The purpose of this paper is to make extensive study on the essence of impingement / effusion film cooling , and the research results will be applied in futural study on the higher performance aeroengine 本文旨在对冲击-发散复合冷却技术开展机理和基础性研究,研究成果可应用于更高推重比级发动机预研。 |
| 9. | With the development of multi - variable control technology and aero - propulsion technology , future excellent engine must have the character , which is high ratio in thrust and weight low fuel and long use life . therefore the control system of aero - engine has also been becoming more and more complicated . the precision of control system is also extra higher 随着高推重比、低油耗、长使用寿命、高机动性航空发动机的研制,现代航空发动机需要控制的变量越来越多、精度越来越高,因此,航空发动机控制系统变得越来越复杂,传统的航空发动机控制系统是采用机械液压控制。 |
| 10. | Compress disk is the very important rotational component in the areoengine . when the compress disk is working , the grads of temperature and stress between the rim and the center of the disk are great . in order to raise the thrust - weight ratio of the disk and reduce oil consumption . the best prospective way is the dual alloys disk used 压气机盘是航空发动机上一个很重要的转动部件,压气机盘工作时,轮缘和轮毂温度梯度和应力梯度较大,为了提高飞机发动机推重比、减低耗油量,要求压气机盘的工作温度、使用性能更高,双合金盘制造是最有发展前景的技术。 |
