查询词典 prism level

I hope that once upon a time a manufacturer decides to pick up this design and produces a modern 8x50 Porro prism binocular, with a reasonable price tag (which could be around 700 Euro), and on a quality level of this old Zeiss.

我期望先前某厂家决定再启用这个设计生产现代化的8x50保罗镜，有一个合理价格（应该大约700欧元），并且质量水平和这个老Zeiss镜一样。

Since 1988, the phase-correction coating (also called P-coating) was implemented, which shifted the level of contrast to that of the better Porro prism binoculars. The present sample was made around that time and already contains the P-coating.

从1988年起，phase-correction 镀膜被应用，相对更好的保罗棱镜望远镜的镀膜，它拉近了等级，当前样品就是那时生产的并且使用了P镀膜。

On the base of other researcher, the *** from the basic equations of stable current field to derived the expressions of boundary problems under 3-D condition. Without considering the EM effect and using the generalized variation principle, we can get the corresponding variation equation. Thronging subdivide the 3-D model, interpolation, analysis, and general synthesis with the triangular prism element, we can carry out the simulation on frequency-domain IP\'s parameters under level and undulate topography.

在前人工作的基础上，在忽略电磁效应的情况下，从稳定电流场的基本方程出发，推导了三维区域满足的边值题目，用广义变分原理得到相应的变分题目，通过用三棱柱单元对大地模型进行剖分、插值、总体集成，最后解方程，得到每个节点上的复电位值，最后实现了水平和起伏地形等条件下的激电参数的数值模拟。2。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
