| 1. | Tio _ 2 can use a very small portion of solar energy because it only can be excitated only by ultraviolet radiation 由于tio _ 2只能被波长较短的紫外线激发,使其太阳能的利用率低。 |
| 2. | The luminous intensity of phosphor - powder synthesized by this method is 32mcd / m2 after the sample was excitated 300s , and the decay time of the sample is 350min 该法制备出的发光粉激发后300s时的余辉强度32mcd m ~ 2 ,测量余辉时间为350min 。 |
| 3. | Due to the success in yantan project , the similar method are applied in three gorges project , the maximal potential vibration excitated by hydraulic disturbance of hydrogenerator set in three gorges hydropower house are estimated 在此基础上将本文方法应用于三峡工程,对三峡厂房在机组垂直动荷载作用下的最大可能振动作了计算预测。 |
| 4. | There is no effective method to forecast and estimate the hydraulic vibration of hydraulic turbine up to now in the world , much less research in - depth for powerhouse structure resonance excitated by hydraulic disturbance of hydrogenerator set 目前国内外尚无完善的水轮机水力振动预估方法,而对机组水力振动引起的厂房结构共振更是未深入研究。 |
| 5. | Interactively teaching on web makes it certain to provide compound information of pictures , words , sound and animations . so , students " interests are excitated and the teaching becomes lively and ready to be absorbed 在web上进行交互式教学,可以实现图文并茂、声音动画等综合信息的传递,提高了学生的兴趣,使得课堂教学生动活泼,更易接受。 |
| 6. | Because of the resonant interaction between the reb electrons and the wave excitated by the embp instability , the reb electrons cannot transport continuously , but in form of current clumps . the transport velocity is close to the phase velocity of the wave 因为embp不稳定性所激发的波和束流电子之间的共振相互作用,束流电子不是连续地传播,而是以电流团的形式传播,传国防科技大学研究生院学位论文播速度接近于波的相速度。 |
| 7. | Thus , space - charge field in excitated photoconductor can intensity influence not only the shape of photo - electric current of pcss ' s , but also the terahertz out put of photoconducting antenna . in this paper , the forming and movement of space - charge field are simulated by means of fdtd method 触发条件下光电导体内部电场不仅显著的影响光电导开关产生超快电脉冲的功率、波形,而且对thz偶极天线的辐射功率也有明显的影响。 |
| 8. | The good agreement showed the validity of the analytical methods . a new scheme of the complex excitated lsm is also proposed , which incorporates the advantage of electrical excitated lsm and permanent magnet lsm . this technique has potential application in the field of maglev 论文还提出了一种混合励磁的直线同步电机的概念设计方案,它结合了电励磁直线同步电机和永磁直线同步电机的一些优点,在磁悬浮技术中有较好的应用前景。 |
| 9. | The works we have done as below : the design of whole structure of the non - confocal lif detection system ; the design of the device to couple excitated light into the smf , transport 532nm and 635nm laser direct to the detection area ; designing the device to divide , filter and detect the fluorescence signal 本论文研究这种微流控生化分析系统的激光诱导荧光检测部分。作为该系统的第一阶段研究工作,本课题进行了以下工作: 1非共焦型lif检测系统的总体结构设计。 |
| 10. | The outlines of thesis are as follows : for the configuration of gis and the characteristic of partial discharge , the thesis analyses the electromagnetic waves excitated by the pd signal and the reason of a coupler built in gis inducing pd signal in terms of the electromagnetic theory and antenna theory 主要工作有:针对gis结构及内部局部放电特点,分析了发生局部放电后信号所激发的电磁波传输特性,并从电磁场理论及天线理论角度分析内置传感器的局部放电耦合原理。 |
