| 1. | The problem of the microvoid is of considerable significance .
微观空穴仍是极其重要的问题。 |
| 2. | There is no void .
不存在空穴。 |
| 3. | These crystal lattices may have imperfections, such as dislocations and vacancies .
这些晶格可能有不完善之处，例如位错和空穴。 |
| 4. | We now believe that these materials conduct by a process known as hole conduction .
现今我们知道，这些材料的导电过程是所谓“空穴导电”。 |
| 5. | Exciton is electron-hole pair held together by their mutual coulomb interaction .
激子就是由电子和空穴在相互间的库仑力作用下，相互维持在一起的电子--空穴对。 |
| 6. | The other way was to knock a bound electron off a neutral atom creating simultaneously an electron and a hole .
另一种方法是把束膊电子从中性原子中撞出，同时产生电子和空穴。 |
| 7. | Under application of an electric field, the electron and hole move in opposite directions at different velocities .
在电场的作用下，电子和空穴以不同的速度沿着相反的方向运动。 |
| 8. | All these prevent the electrons and holes from continuing their steady motion as quasi-free particles, and introduce scattering .
所有这些影响都会妨碍电子和空穴去继续它们作为准自由粒子的稳定运动，而引起散射。 |
| 9. | The cost for the deposition of the waste depends also upon the volume of the storage cavities and the maximum allowable radioactive concentration of the waste .
废料处理费用还取决于贮存空穴的容积和允许的废料最大放射性浓度。 |
| 10. | The process of photoluminescence refers to the radioative recombination of electronhole pairs generated by shining high energy light on a crystal .
光致发光过程就是高能量光子照射到晶体上之后，晶体所产生的电子一空穴对的辐射复合过程。 |
