查询词典 lattice

If P is a convex lattice polygon, and its pair-wise disjoint family of translates are also lattice polygons, whose union contains every lattice point, it is called a TLP .

若P为凸格点多边形，其内部边界不交平移覆盖平面格点集，则称之为可平移格点多边形TLP。记顶点数为v的TLP的内格点数的下确界为i ，得出i(5)=i(6)=1，i(7)=i(8)=4。

基于格矢量量化的图像水印：本文提出了基于格矢量量化的多比特盲水印算法，不需要原始图象就可以实现水印信号的检测和译码。

If a phototypesetter is an intermittence type, the memory of controller is used only to buffer a section and the buffer of whole page lattice is unnecessary. If a phototypesetter is an uninterruption type, a section of lattice is only generated and buffered for every time and then be converted into black-white sectional information, whose information quantity is much less, by microprogram for buffering whole printed sheet. On scanning, the black-white sectional information is real-restored into lattice to output.

当照排机是&走走停停&类时，控制器的存储器只需缓冲一段，而不必缓冲整版点阵；当照排机是&不许停顿&类时，则用分段方法每次只生成一段点阵并缓冲，然后用微程序把这一段点阵转换成信息量少得多的黑白段信息作整版缓冲，扫描时在实时下把黑白段信息复原成点阵输出。

Based on the production of other researchers such as professor Xu Yang and professor Qin Keyun, this paper discusses the structure and properties of lattice implication algebra, tautologies in some lattice-valued systems, automated reasoning methods, lattice-valued propositional logic system.

本文的工作是在徐扬教授、秦克云教授等研究成果的基础上，对格蕴涵代数的性质、结构、格值命题逻辑系统中的重言式、自动推理方法、格值命题逻辑系统等进行了一些研究。

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。

Dynamic characteristics of Kiewitt cable-supported lattice shells ;2. Stability and static analysis of cable-supported lattice shells ;3.
