Results Complications of deep white candidiasis infection inside the hospital mostly took place among patients suffering from chronic respiratory diseases, malignant tumors and nosohemia,accounting for 59.09%.Infection was in direct proportion with the length of hospitalization.The chief factor leading to infection was the long-term use in large doses of wide-spectrum antibiotics,especially the use of the third-period cephalosporins,which are wide in spectrum and strong in killing bacteria.White candidiasis infection results from the composite action of multiple dangerous factors. Ofthose infected,40.91%used hormone and 11.36% used immunosuppressive agents as well as radiotherapy and chemotherapy. The application of trauma examination and curing also created conditions for the occurrence of infection.

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm，与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比，具有向短波长方向移动的特点，据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩；长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征，而基性超基性岩石显示Fe2+和Fe、MgOH特征，利用不同的铁价态和次要矿物可以区分它们：ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度；砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物，在221 μm（band 6）存在有特征的吸收谱带，并且在165 μm（band 4）具有较高的反射率，而蓝片/绿片岩在221 μm（band 6）反射率较高，不具有明显特征吸收谱带，同时其在165 μm（band 4）反射率较低，因此蓝片/绿片岩ASTER band4/band6 比值低。
