查询词典 sphere gap

However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.

把两种或两种以上材料组合起来实现优异性能材料的方法是一种经常使用并行之有效的方法，本论文就是对GaP、GaAs与GaN形成合金系GaP_(1-x)N_x和GaAs_(1-x)N_x进行基础性研究的结果，人们预测这种合金系的禁带宽度应在磷化镓的2.261eV(或砷化镓的1.43eV)到氮化镓的3.39eV之间，如果能制成上述合金系则是很有意义的，它是很有希望的蓝色发光材料。

本发明提出一种打印机，它保持输送皮带与在输送皮带的输送方向上延伸较长距离的打印头之间的间隙沿着输送方向均匀一致，并且增加或减小沿着输送方向的均匀间隙。

Works on the bending roll system of four-roll rolling mill, the workroll shape variation caused by the force of bending roll and the contact stress between rolls was researched with the FEM software ANSYS, the maximum deformation of the work roll was calculated, and the curve of the gap adopting the Least-Squares method was fitted, which set the base of the further calculation of load-gap shape.

以四辊轧机的弯辊系统为研究对象，利用有限元分析软件ANSYS研究弯辊力和辊间接触应力引起工作辊形状的变化，计算工作辊弯曲的最大变形量，并用最小二乘法对辊缝曲线进行拟合，为进一步计算有载辊缝形状提供可靠的理论依据。

Result With young elm forest-pumpkin strip intercropping, since the branch tendril covered the gap between pumpkin planting-ditches and elm forest land, the soil moisture was remarkably increased. And the water use efficiency under intercropping increased by 23.7%-163.3% compared with the sole cropping. Elm-pumpkin strip intercropping changed the sequential succession trend of the grasses growing in the gap of the pumpkin planting-ditch, annual grasses became the dominant vegetation, and the feeding nutrient matter content and yield of the annual grasses increased significantly.

榆树幼林与南瓜间作后，瓜蔓覆盖地面，显著提高了南瓜行间和榆树林地的土壤水分含量，林－瓜间作地水分的利用效率较单作提高了23.7%~163.3%；间作改变了南瓜行间杂草群落自然演替的方向，一年生杂草成为优势物种，其饲用营养物质的含量和产量较林带间杂草显著提高。
