| 1. | Clouds are sometimes seeded with silver iodide to induce precipitation .
人们有时在云里播撒碘化银，以诱使降雨。 |
| 2. | Aircrafts fly above and beside the storm clouds and drop tiny silver iodide crystals into them, triggering rainfall .
飞机飞行于风暴云之上及其周围，向风暴云中撒播碘化银晶粉以激发降雨。 |
| 3. | Unlike dry ice pellets , the particles of silver iodide do not evaporate when released
与干冰粒不同，碘化银微粒在投放时并不蒸发。 |
| 4. | The thickness of the silver iodide film is controlled by the concentration of the iodine and the reaction time
碘化银膜的厚度主要由碘化的浓度和时间来控制。 |
| 5. | Silver iodide nano - powder has been produced by salt of silver and iodide in an alcohol solvent . the optimal conditions of the process has been studied by latin square experiments
摘要乙醇中采用银盐和碘化物制备碘化银纳米微粉。用拉丁方格实验法确定合成过程中的适宜条件。 |
| 6. | Release of silver iodide ( agi ) into an existing supercooled cloud ( i . e . , air temperature between - 39 and - 5 celsius ) can convert water vapor to ice crystals , which is called sublimation
将碘化银播洒至已形成的过冷却云中（既空气温度在- 39摄氏度? - 5摄氏度）能将水汽转化为冰晶，这个转化过程被称为凝华。 |
| 7. | While the concentration of the iodine is o . oim and the reaction time is 60s , the thickness of silver iodide film is about 0 . 7um . in this condition , the silver iodide has two crystal types , the main type and few y type , and the transmission efficiency reaches the maximum
在碘化浓度为0 . 01m ( i _ 2的ccl _ 4溶液) ，碘化时间为60s左右，碘化银的晶型主要为和型，其中型较多，膜厚约为0 . 7 m ，此时空芯光纤的传输率最高。 |
| 8. | These offices , set up over the past 15 years , deploy artillery , rocket - launchers and aeroplanes to seed clouds with chemicals （ usually silver iodide ） that encourage droplets to form and fall where needed , or prevent the formation of destructive hailstones
在过去的十五年中，这类办公室相继成立，它们调动大炮、火箭发射器和飞机，利用化学品（通常是碘化银）来"播云" ，作用要么是促进雨滴形成后降到需要雨水的地方，要么是防止破坏性冰雹形成。 |
| 9. | Because of the restriction of the performances of the infrared materials , we decide that the hollow waveguide should have the structure of single layer dielectric coated metallic film according to the general analysis of process controllability and transmission capability . the dielectric we choose is silver iodide , made from silver and iodine , and the optimum thickness is about 0 . 77um
因材料性能的限制，通过传输性能以及工艺可控性综合分析，确定制备的空芯光纤为单层电介质涂覆金属膜结构，电介质膜定为碘化银，理论厚度为0 . 77 m左右，由银膜直接碘化得到。 |
