| 1. | In sicp / al composites , the main defects are hole and very inhomogeneous distribution of sic particles 在所测的sicp al复合材料工件中的缺陷主要是sic粒子分布不均匀以及材料中存在气孔。 |
| 2. | Scanning electron microscopy ( sem ) was employed to examine the worn surfaces ^ shape of wear debris ^ dispersion of nano - a ^ os and wear mechanism 采用扫描电子显微镜观察、分析磨损表面形貌,磨屑形状,纳米粒子分布情况及磨损机理。 |
| 3. | So based on the given operating range , the reasonable pore rate and position of heterogeneous pores distributor can be determined to obtain the distribution of particles as homogeneous as possible 所以应根据不同的操作条件选择合适的变孔径分布板,以得到较均匀的粒子分布。 |
| 4. | The numerical analysis shows that the existence of ( superscript - ) meson condensate has an obvious influence on the particle fractions of neutron star matter 研究表明, (上标- )介子凝聚的存在对中子星物质的粒子分布有明显影响,使(上标- )粒子出现推迟, (上标+ )粒子出现提前。 |
| 5. | In the second part , a few kinds of particles with different densities and sizes were picked and used to study the trajectories and the distributions inside the pump impeller 在第二部分工作中,精心选择几种不同密度、不同大小粒子,进行叶轮流道内粒子运动轨迹和粒子分布的实验研究。 |
| 6. | Here based on the kinetic theory , we have mainly discussed the distribution function of the component particles in qgp which is in quasi - equilibrium . our discussion can be divided into two aspects Jtwa硕士学位论文w一步m仅盯e厂stiesis本篇论文的工作就是研究近平衡态下qgp成分粒子分布函数的特性。 |
| 7. | The results indicated that the obtained thin films at different treatment conditions existed great difference . tio2 nanometer particles distributed homogenously on the film a and its surface was uniform , compact and crack - free 而在500 ,热处理lh所制膜上纳米粒子分布均匀,所生成的次级颗粒很小,表面粗糙度也很小。 |
| 8. | In the theoretical framework of the relativistic mean field , the influences of ( superscript - ) meson condensate on the equation of state and the particle fractions of neutron star matter including delta isobars are studied 摘要在相对论平均场理论框架下研究了(上标- )介子凝聚对包括共振态的中子星物质状态方程及其粒子分布的影响。 |
| 9. | For the clouds over xi ' an region , the quantity calculations of the backscattering cross sections for various reflection mechanism of cloud are dealt with . the results calculated show that the major contributions for the backscattering cross s ection come possibly from average cloud diameter , clear - air and humidity turbulence and also from distributions of cloud particles , especially , at higher frequencies 再分析了云的后向散射机理,计算了西安地区云的后向散射截面;表明影响云的后向散射截面的主要因素为云滴平均半径、大气湿度湍流及云粒子分布,在较高频率时更显著。 |
| 10. | The present dissertation discusses two issues in the laser plasma interaction . in the first part , we introduce the basic concepts about laser plasma interaction and simulation , and give the simulation results concerning the influence on the propagation of the laser pulse in plasma , exerted by the spatial modulation on the surface of the preformed plasma 第一部分简单介绍了激光等离子体相互作用物理与模拟的一些基本情况和基本概念,并模拟研究了靶表面等离子体的空间调制对激光传播的影响,分析了等离子体温度诊断问题及激光等离子体相互作用过程中粒子分布函数的特征。 |
