Long-term chemical N and P fertilization increased soil Cd concentration significantly,but soil Cd accumulation.
结果表明:在完全不施肥的自然农业生产条件下黑土Cd浓度略有增加;长期定量施用氮磷化肥使黑土Cd浓度显著增加,但不同化肥用量对黑土Cd积累的影响无显著差异;长期施用猪粪可显著增加黑土Cd的积累,且近年来有加速积累的趋势,含Cd饲料添加剂可能是猪粪中Cd的重要来源;施用氮磷化肥对黑土Cd的有效性无显著影响,长期施用猪粪则可显著提高黑土Cd的有效性。
After annealing at 600℃, the test removes the bigger Cd precipitates (>5μm) and improve CdZnTe wafer s transmittance, FWHM and EPD.
在CdZnTe晶体生长时,有时会产生大颗粒的沉积相,严重的影响了CdZnTe晶片的质量,通过电子探针测试证明其为Cd沉积相。
