sublayer
subsurface stratum
Examples
- This form has also accumulated in the subsurface horizons of many soils in humid regions .
这种钙形态在湿润地区许多土壤的亚表层也有累积。 - Standard practice for subsurface site characterization of test pits for on - site septic systems
现场腐化系统试验坑亚表层场地特性的标准规程 - Standard guide for use of hollow - stem augers for geoenvironmental exploration and the installation of subsurface water - quality monitoring devices
亚表层水质检测装置安装和地理环境勘探中空螺旋钻使用的标准指南 - After analyzing purple soil sampled from neijiang , leshan ofsichuan provinec and yuanmou of yunnan province , the contrast results of microbe quantity feature between surface and subsurface purple soil were obtained as follows . the content of soil organic matter , total and available nitrogen , phosphorous and potassium of surface was higher than subsurface , not relating to the type of purple soil and soil utilization way . the quantity of microbe _ bacteria , actinomyces and mould in surface purple soil was higher than subsurface , which indicated that the organic matter and airy condition in surface soil was more suitable for microbes growing . there was the same tendency in profile change of microbe quantity in purple soil located in temperate _ humid climate of sichuan basin in contrast with dry _ hot climate of yuanmou , yunnan . the nutrient situation of purple soil in sichuan basin shown that state of surface was better than subsurface , while in yuanmou of yunnan the state was on the contrary due to the degradation of surface soil
实验室对四川内江、乐山和云南元谋不同类型紫色土表层和亚表层微生物数量特性的比较分析表明：土壤有机质、氮磷钾全量及其速效量均表现为表层高于亚表层，与紫色土类型和利用方式无关；三大类土壤微生物细菌、放线菌和霉菌数量均表现出表层高于亚表层，表明紫色土表层的有机质和通气性优于亚表层，适宜于这三大类微生物生长；温湿气候条件下的四川盆地和干热气候条件下的云南元谋其紫色土微生物数量的剖面变化具有相同的趋势，唯土壤营养状况在四川盆地紫色土中表现为表层优于亚表层，而在云南元谋紫色土中由于表层土壤的退化作用表现为亚表层优于表层的相反情况。 - Along the elevation gradient or succession series , the activity of alkaline phosphatase increased gradually . besides the surface sediments * alkaline phosphatase of sediments in every vegetation area has higher peak activity and vmax , but a lower km at the depth of 20 - 30cm . lt was proved that there was a remarkably active zone of the alkaline phosphatase in the sediments besides the surface layer
而各植被样带沉积物中碱性磷酸酶活性、 vmax除在表层有一高值以外，各植被样带在20 - 30cm处有一较高峰值，而km值在该处有一较低值，说明除了表层之外，在亚表层有一个令人注意的碱性磷酸酶活跃区。
