请知道的回答,最好有详细解释和出处,谢谢
金星的两个翻译,有何不同,希望知道的人说明他们的区别,最好有来历和详细解释,谢谢,宁缺毋滥,hesper是长庚星

Hesper才是金星

phosphor和phosphorus是 磷 的意思。
“磷”:就是做火柴的那种东西,磷火,星光。
“金星”:又叫启明星、早上才出来的。
所以在诗里Phosphor就成了金星了

EFFECT OF STEAM TREATMENT AND PHOSPHOROUS ACID MODIFICATION OF HZSM-5 ON ITS PHYSICOCHEMICAL AND CATALYTIC PROPERTIES

Abstract:Physicochemical and catalytic properties of phosphorous acid modified HZSM?5 ze olites treated with 100% steam at 673,873,and 1073*!K have been investigated.T he structure of the samples was characterized by XRD.The acidity and distributio n of the acidic sites were studied by IR using pyridine as probe molecule and te mperature programmed desorption (TPD) of ammonia.The state of phosph orus were studied by XPS,showing that P (Ⅲ) was oxidized to P (Ⅴ),a model for the surface structure of the modification is proposed.Th e textural properties of catalysts determined by nitrogen isothermal adsorption ?desorption measurements suggest the isothermal type of all samples is a combin ation of type Ⅰ and type Ⅳ,all hysteresis loops resemble the H4?type in the IUPAC classification.The state of aluminum was characterized by 27 Al MAS N MR spectroscopy.AM1 (Austin model) semi?empirical method and cluster model method have been employed to study the stability of two possible phosphor us modified zeolite geometries,the difference was the bridging oxygen of phosph orus coordination with aluminum or the terminal oxygen of phosphorus coordinatio n with aluminum.The result showed that the terminal oxygen coordination was more possible according to the heat of formation (HF).The ?n??heptane cracking reaction was selected as probe reaction to investigate the activity of studied samples.?
Keywords:HZSM?5 zeolites;steam treatment;phosphorous acid modificati on;texture;cracking activity

亚磷酸和水蒸气联合改性的HZSM-5的物化性质和催化性能研究

吕仁庆 唐博 王震宇 王秋英 项寿鹤

摘 要:考察了由亚磷酸改性的HZSM-5在673、873和1073K温度下100%水蒸气处理样品的物化和催化性质.采用XRD表征了样品的结构.通过吸附吡啶红外光谱和NH3-TPD进行了酸性和酸分布研究.XPS的研究结果表明,P由+3价氧化成了+5价,并提出了可能的改性的表面结构模型.通过N2吸附-脱附等温线研究了样品的孔结构,样品的吸附-脱附等温线为Ⅰ型和Ⅳ型的复合型,滞后环为IUPAC分类的H4型.Al的状态由27Al MAS NMS表征.采用AM1(Austin Model Ⅰ)半经验量子化学方法和模型簇法筛选了磷改性可能的两种结构模型,其区别在于磷上的桥氧与铝配位还是端氧与铝配位,结果表明端氧与铝配位的可能性更大.以正庚烷裂化反应为探针反应考察了样品的活性.
