高温光谱仪

The resulting materials were characterized by x-ray diffraction, Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Photoluminescence. Those spectra reveal that by adding SiO2 to YAG:Ce precursor, the lattice constant decreases while vacancies are generate due to the co-dopant ions (Si4+) replaces in the place of Al3+ sites of YAG:Ce system. YAG:Ce phosphors with Y3+ dodecahedral site replaced by Ce3+ and diffused effectively as an activator, as a result the photoluminescence intensity increased about ~20-30%.

研究成果显示，掺杂SiO2之YAG：Ce萤光粉经过高温热处理后，由X光绕射、红外线吸收光谱仪以及核磁共振可以得知，当SiO2添加量增加时，YAG：Ce晶格常数会因为Si4+取代Al3+的四面体晶格位置而变小，同时产生将YAG：Ce之铝离子空位缺陷，使活化中心更有效地在YAG：Ce主体中扩散取代Y3+的十二面体晶格位置，提高其发光性质约20~35%。

The muffle kiln was used in the small scale experiment of sintering, and the atomic-absorption spectrophotometer was used to determine the contents of heavy metals in the samples. This study investigated the migration characteristics of 6 heavy metals in the sintering process of MSWI fly ash, and analyzed the influence of temperature, residence time, modeling pressure, additive and etc. onto the migration characteristics of heavy metals.

首先，采用高温箱式电炉对垃圾焚烧飞灰进行了小型烧结实验，使用原子吸收光谱仪对烧结前后样品中重金属含量进行测试，考察飞灰烧结过程中6种重金属(Cd、Pb、Cu、Ni、Cr和Zn)的迁移情况，并分析烧结温度、时间、成型压力、添加剂等因素对各种重金属迁移特性的影响。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
