1. 读数值正负的确定，水平仪读数值的正负根据气泡移动方向和水平仪移动方向来确定。如两者方向一致，读数为正值，表示被测表面向上倾斜，如两者方向相反，读数为负值，表示被测表面向下倾斜。 2. 读数基准的选择，水平仪读数基准有二：一是按水平读数，它是以水平仪的零位线为基准进行读数，这时的读数值表示被测面在一定长度上对自然水平面倾斜的高度差（水平仪必须做好零位检定调整），亦是被测面对自然水平面所倾斜的夹角，二是按相对水平读数，这时的读数值是表示被测面所选基准线方向倾斜的夹角或在一定长度上所选基准方向倾斜的高度差。

水平仪怎么读数: 水平仪放在1m的台面上，泡泡往左边跑1格，那就是左边高了0.02mm；那放在2m的台面上，也往左边跑了1格，这情况下怎么理解呢。两次平行度一样的吗？麻烦高手们指点下。... 水平仪放在1m的台面上，泡泡往左边跑1格，那就是左边高了0.02mm；那放在2m的台面上，也往左边跑了1格，这情况下怎么理解呢。两次平行度一样的吗？麻烦高手们指点下。展开

请高手帮我翻译一下这一段。。。: Carbonnanomaterialsarenovelmanufacturedmaterials，havingwidespreadpotentialapplications.Adsorptionofhydrophobicorganiccompounds(HOCs)bycarbonnanomaterialsmayenhancetheirto... Carbon nanomaterials are novel manufactured materials， having widespread potential applications. Adsorption of hydrophobic organic compounds (HOCs) by carbon nanomaterials may enhance their toxicity and affect the fate， transformation， and transport of HOCs in the environment. In this research， adsorption of naphthalene， phenanthrene， and pyrene onto six carbon nanomaterials， including fullerenes， single-walled carbon nanotubes ， and multiwalled carbon nanotubes was investigated， which is the first systematic study on polycyclic aromatic hydrocarbons (PAHs) sorption by various carbon nanomaterials. All adsorption isotherms were nonlinear and were fitted well by the Polanyi-Manes model (PMM). Through both isotherm modeling and constructing “characteristic curve”， Polanyi theory was useful to describe the adsorption process of PAHs by the carbon nanomaterials. The three fitted parameters (Q0， a， and b) of PMM depended on both PAH properties and the nature of carbon nanomaterials. For different PAHs， adsorption seems to relate with their molecular size， i.e.， the larger the molecular size， the lower the adsorbed volume capacity (Q0)， but higher a and b values. For different carbon nanomaterials， adsorption seems to relate with their surface area， micropore volume， and the volume ratios of mesopore to micropore. Quantitative relationships between these sorbent properties and the estimated parameters of PMM were obtained. These relationships may represent a first fundamental step toward establishing empirical equations for quantitative prediction of PAH adsorption by carbon nanomaterials and possibly other forms of carbonaceous (geo-) sorbents， and for evaluating their environmental impact. In addition， high adsorption capacity of PAHs by carbon nanotubes may add to their high environmental risks once released to the environment， and result in potential alteration of PAHs fate and bioavailability in the environment. 展开
