| 1. | Analyses on the first strong precipitation process in 2006 summer in changzhi city 长治市2006年夏季首次强降水过程分析 |
| 2. | The heating rate of the precipitation process is also adjusted to correspond to the rainfall amount observed 此外,降水过程的加热率亦会相应地调整,以符合实况观测的雨量。 |
| 3. | Two cases of spring stratus precipitation processes occurred during march 30 to april 2 , 2003 and april 4 to 5 , 2002 have been analyzed in this paper 本文对2002年4月4 5日和2003年3月30日4月2日河南省两次春季层状云降水个例进行了分析。 |
| 4. | In this process , the moisture of the initial field between the lifting condensation level and the cloud top at the point where rain is observed is adjusted to allow precipitation process to be switched on 在这个过程中,初始场中降雨区域上空,位于抬升凝结高度与云顶之间的湿度会予以调整,作用是要启动降水过程。 |

| 6. | Additionally , it was the precipitation process of suspended phosphorus that played a relative important role in phosphorus removal in cold periods , and that was adsorption / complexation of dissolved inorganic phosphorus in warm periods 此外,低温期悬浮磷的沉积作用除磷效率高;高温期溶解无机磷的吸收络合作用除磷效率高。 |
| 7. | The test results have showed that the w - cu powder produced by the homogeneous precipitation process has a near spherical shape , a particle size ranging from 50 to 200nm and a uniform distribution of w and cu gradients 研究结果表明,均相沉淀法制备的w - 30wt . cu复合粉末颗粒明显呈球状, w 、 cu组分呈均匀、弥散分布,透射电镜观测显示其粒径范围在50 - 200nm之间,为超细粉体。 |
| 8. | Abstract : new methods of preparing rare earth doped yag phosphors , which contain sol - gel , macro - molecule network gel and precipitation process , were summarized . the structure , luminescence property and grain sizes of the phosphor powders were also described 文摘:本文总结了稀土离子掺杂的钇铝石榴石发光粉末合成的新方法,包括溶胶-凝胶法、高分子网落凝胶法、沉淀法等,并介绍了这些发光粉的性能。 |
| 9. | The key to the stochastic modeling is to build a suitable stochastic model of precipitation . in resent years , most models of precipitation process have been developed under some hypothesis or using advaced mathematical tools , but the applicability of these models is not strong 地区干旱随机模拟研究的关键是建立合适的降雨过程随机模型。目前给出的大多数降雨过程随机模型,尽管运用了较多的假定条件或高深的数学工具,但适用性不强。 |
| 10. | The main contents of this dissertation are summarized as follows . ( l ) by investigating and preparing the ceo2 nanoparticles with various precipitators we choosed the cerium ( iii ) nitrate , hydrogen peroxide and ammonia as the materials to prepared the nanoparticles by a two - stage precipitation method the process differents from the general precipitation process 试验的主要研究内容: ( 1 )通过不同沉淀剂的制备研究,选择以硝酸铈、双氧水和氨水为基本原料,经过铈( )离子的氧化和铈( )离子的沉淀两个主要过程制备纳米二氧化铈。 |
