钼的

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

The molybdic acid aggregates with diameter of 1--2μm and length of several decades-micron can be obtained by the reaction of higher-concentration ammonium molybdate with HNO3 in a coexisting HAc or CTAB solution, repectively.

较高浓度的钼酸铵分别在醋酸和CTAB调节下与硝酸反应均可制备直径为1~2μm，长为数十微米的细长晶须，经过500~600℃烧结后则相应变为纳米级片状和颗粒状α-MoO3粉体；低浓度的钼酸铵在CTAB调节下与盐酸反应可制备不规则的晶体棒，经过烧结后得到颗粒状α-MoO3粉体。

Comparing the two kinds of catalyst, although the high conversion could been gotten at the optimum reaction conditions respectively, to the same conversion, the reaction conditions for ammonium molybdate catalyst were higher than that for sodium tungstate catalyst, that means the catalytic activity of ammonium molybdate is higher than that of sodium tungstate.

两种催化剂相比，虽然在最佳工艺条件下，均可使反应达到较高的转化率，但达到相同转化率时钨酸钠催化剂所需的反应条件比钼酸铵催化剂高，所以总体来说，钼酸铵催化剂的反应活性高于钨酸钠催化剂。

Imageological methods, such as ultrasound and molybdenum tarsget are not sensitive for the diagnosis of breast sclerosing adenosis. IHC staining of myoepithelium is an important for the diagnosis of breast sclerosing adenosis demarcated with breast cancer. Non-palpable lesion of breast sclerosing adenosis can be surgically exsected with the guide wire localization under molybdenum target.

B超、钼靶等影像学方法对于诊断硬化性腺病的敏感性较差；免疫组化染色肌上皮标记SMA、P63是鉴别乳腺硬化性腺病与乳腺癌的重要指标；对于不能触及病变的硬化性腺病可采用钼靶摄片下钢丝定位后外科切除。
