| 5. | It has revealed that emission can be obtained at field as low as 5 v / m , and the field emission measurements were carried out at pressure of 10 - 4pa
经过场发射测试,包银金刚石的阈值电场为5v / m ,场发射测试过程真空度为10 - 4pa 。 |
| 6. | In this research , field emission performances from diamond film growing through epitaxy method and diamond powders coated with sliver have been studied
本文研究了外延法生长金刚石薄膜和包银金刚石颗粒的场发射特性。目的在于探索金刚石的场发射机制。 |
| 7. | It can be seen from the experiment results that field emission performance of pure diamond is not very good . after eptitaxy and silver coating , its field emission performance can be well improved . it is expecting to realize low - voltage electron and high current density field emission
从实验数据上看,电泳金刚石的场发射效果不十分理想,但经过外延生长和包银处理后,场发射特性得到了明显的改善,这说明金刚石表面修饰对金刚石场发射有重要意义。 |
| 8. | The ag - coated composite powder is a kind of addition agent , which is of great value in the application in the fields of conducting resin , wave - absorbing materials and optical apparatus . the importance of the composites could be attributed to the good associativity between ag and the powder and the equably coating of silver on the substrate
包银复合粉体作为一种添加剂在导电浆料、吸波材料及光学器件等领域具备很高的应用价值，银与粉体具备很好的结合性并且能均匀包覆在基体表面达到上述应用要求的一个关键。 |
| 9. | Because pure silver is so soft , it should only be used when malleability is required , such as in handcrafted jewelry featuring weaving and other intricate designs . sterling silver is most often used for jewelry and household accessories because of its combination of beauty and durability . acceptable quality marks for sterling silver include
2折弯法：用手轻折银首饰，易弯不易断的成色较高僵硬勉强折动的成色较低经折弯或用锤子敲几下就会裂开的为包银首饰经不起轻折，且易断的为假货。 |
| 10. | The small amount of copper added to sterling has very little effect on the metal s value . instead , the price of the silver item is affected by the labor involved in making the item , the skill of the craftsperson , and the intricacy of the design . most high quality silver items are stamped with a " fineness " , " 925 " or " quality " mark
