    摘要： High pressure sodium lamps have been subject to progressive reduction in pressure of contained sodium with attendant reduction in lighting quality. It has now been discovered that modification of lamp components permits the pressure of contained sodium to be maintained at higher levels. Emission materials enclosed within the lamp are altered to limit reactive oxygen in the lamp atmosphere. A thermionic electrode is equipped with an improved emission mix composition as illustrated in areas A and B of the triaxial plot of Figure 3 and an oxygen getter is intermixed with the mix composition. The oxygen getter is a metal which forms a highly stable oxide and may be at least one selected from the group consisting of titanium, zirconium, hafnium, tantalum and yttrium.

    摘要： A material and an article comprising the material are disclosed. The material comprises a plurality of structural components (100). The structural components (100) are configured in a series of increasing structural component size classes. The series has a base unit size class (102) and at least one modular size class (104), and a component of the at least one modular size class (104) comprises a plurality of components of the next smaller size class in the series. The structural components of the base unit size class (102) comprise at least one bulk phase (103), and the structural components (100) are bonded together at interfaces (112). Mechanical damage originating within a modular size class structural component (104) is energetically favored to propagate in a distributed fashion among the plurality of structural components contained within the modular size class structural component (104).
