Wastewater from a pharmaceutical factory preparing traditional Chinese medicines was used as substrate. While degradation of substrate by IC ( Intermittent Cycle) technology was examined the ability of biological removal of phosphorus and nitrogen, technological conditions and mechanism were also studied. 本文以中药制药废水为对象,探讨了IC(IntermittentCycle)工艺在基质降解的同时,其生物除磷的能力,各种因素对生物磷、氮去除的影响,以及工艺条件和机理。
However, cracks initialized in the diffusion layer between substrate and bond coat when TBCs were tested with low cycle fatigue at high temperature. 而在高温低周疲劳条件下裂纹是在粘结层与高温合金基体的扩散层处。
High-quality GaAs epilayer is obtained by employing the technologies of the tilted Si substrate, optimization the low temperature Al ( GaAs) As buffer layer and thermal cycle annealing. 通过探索有偏角衬底、Al(GaAs)As低温缓冲层和循环热退火等技术的最优条件,在Si衬底上外延生长出了高质量的GaAs材料。
