利用电子探针、Ｘ射线能谱、红外光谱和Ｘ射线衍射。初步研究了健康的斑节对虾Ｐｅｎａｅｕｓｍｏｎｏｄｏｎ甲壳和患病对虾甲壳白斑的形貌、无机组成以及所含的钙化矿物。实验结果表明，健康对虾甲壳的内外表面的钙磷原子比分别为１．２—１．４和１．５６—１．６８；在透射光偏光显微镜下，可见到不均匀分布的大小不等的毛发状、树枝状和十字消光放射球纤状雏晶，有些鲕粒中心可包含石英微粒；红外光谱表明，健康对虾甲壳所包含的沉淀矿物主要是胶磷石。患病对虾甲壳表面白斑区的钙磷原子比可达３１．８３—４３．５６，其剖面中间层鲕粒除合少量硫以外，全部都是钙，偏光显微镜和扫描电镜照片清楚地显示泥晶状、放射纤维状、放射花瓣状微晶集合体逐步交代并覆盖胶磷石，红外光谱和Ｘ射线衍射谱都清楚地证实该矿物是方解石。
Using electron probe, X-ray spectroscopy, infrared spectroscopy and X-ray diffraction. Preliminary study of healthy Penaeus monodon Penaeus monodon crustaceans and sick shrimp chylomicron morphology, inorganic composition and contained calcification minerals. The experimental results show that the inner and outer surface of healthy shrimp shell calcium and phosphorus atomic ratio were 1.2-1.4 and 1.56-1.68; transmission light polarizing microscope, uneven distribution of the size can be seen ranging Hairy, dendritic and cross extinction of radioactive spherulites. Some oolitic centers may contain quartz particles; infrared spectroscopy indicates that the shrimp sediments of healthy shrimp carapace are predominantly phos- phinite. The diseased prawn shell surface white spot area of the calcium-phosphorus atomic ratio up to 31.83-43.56, the middle section of the ooze except with a small amount of sulfur, all calcium, polarized light microscopy and scanning electron micrographs clearly show that the crystal Shaped, radioactive fibrous, radiating petal-like aggregates of micro-crystals gradually covered and covered with phos phosite, infrared spectroscopy and X-ray diffraction spectra clearly confirm that the mineral is calcite.
