The degree of hydrogenation of methyl benzoate might be controled by adding the promoters and changing the nano-size of ZnO. For hydrogenation of methyl benzoate to benzaldehyde, the active-structure of a catalyst should be modified to decrease the absorption of benzaldehyde on the surface of it, because benzaldehyde absorbed is hydrogenated easily. Using 30-40％ZnO/γ-Al〓O〓 or Li-30％ZnO/γ-Al〓O〓, a higher selectivity to benzaldehyde is obtained. Hydrogenolysis of methyl benzoate to toluene or benzene is carried out effectively using a catalyst modified. For instance, 45.3％ selectivity to benzene and 100％ conversion of methyl benzoate at 420℃ was obtained over 10％ZnO/MCM-41 with the nano-size particles of ZnO (2.4nm).

也可以通过助催化剂的添加和活性组分的纳米化，并根据苯甲酸甲酯多步加氢反应的特点实行加氢深度的调控：苯甲酸甲酯选择性加氢制苯甲醛中，由于苯甲醛容易进一步加氢，需要对活性结构进行调变，以减弱苯甲醛的吸附，使用30-40％ZnO/γ-Al〓O〓催化剂或Li调变的Li-30％ZnO/γ-Al〓O〓催化剂，可获得较高的苯甲酸甲酯加氢制苯甲醛的活性；采用同样的方式，苯甲酸甲酯选择性氢解为甲苯或苯也获得了较好的结果，如使用ZnO纳米化的10％ZnO/MCM-41催化剂，在420℃，可获得45.3％的苯选择性，苯甲酸甲酯完全转化。

Among these traits is the tooth, which consists of two characteristic mineralized tissues, a highly mineralized surface layer (enamel in tetrapods and enameloid in fish) and a softer body, both supported by basal bone.

Starting from human resources capitalization in the financial accounting, the effect of human resources capitalization upon enterprise management is analysed using comparative and analytical method. It is held that the effects are mainly shown in the contents of financial statements and the changes in structures, in current gains and losses and taxations, the enterprise cupital, enterprise financial management and enterprise operation management.

从人力资源资本化在财务核算中表征入手，运用对比分析方法，分析了人力资源资本化对企业管理的影响，认为这一影响主要表现在使财务报表的内容和结构发生变化、对当期损益与纳税的影响、对企业投资资本的影响、对企业理财的影响以及对企业经营目标的影响等方面。

The high temperature metallurgical properties of several burdens for Anyang steel were investigated. The results showed that RIof high basicity sinters was better than others, but the RDI(low temperature reduction degradation index) of it was the highest; the RDI and molten dripping property of pellets and lump ores were well, so we can get rational burden structure by combining sinters for blast furnace.

系统分析了安钢炼铁生产中几种常用炉料的高温冶金性能，结果表明，安钢自产高碱度烧结矿具有较好的还原性，但其低温还原粉化率却是最高的；酸性球团矿及块矿则有着较好的低温还原粉化指数及良好的熔滴性能，能够与高碱度烧结矿搭配形成合理的综合炉料结构，满足高炉冶炼要求。

刚化技术和刚化材料是空间充气展开结构的一项关键技术。

The structure of sulfonated polys from DB is similar to that of sulfonated poly(arylene thioether phosphine oxide)s from TB. The latter could be regarded as the"product"of the former provided that the ether unit of the former was replaced by the thioether unit. The studies illustrated that the latter exhibited much better oxidative stability than the former. This is due to the fact that the thioether unit of the former was oxidized into the sulfone or sulfoxide unit in Fenton reagent, which inactivated the adjacent benzene rings and thus retarded the degradation reaction.

从结构上看，后者可以看成是前者的醚基团被硫醚基团取代后的&产物&，其耐氧化性能比前者好得多，这是因为后者的硫醚基团在Fenton试剂中被氧化成为砜或亚砜基团，而砜或亚砜基是钝化基团，钝化了与之相连的苯环，阻碍了降解反应。

Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃，沸点560℃，相对密度1935，F外围电子结构为5d46s2，在化学反应时很容易丢掉1—6个电子，也能得到1—2个电子，所以氧化数为0、±1、±2、＋3、＋4、＋5和＋6，以＋6价化合物最稳定，如WO3不溶于水，空气中的钨会形成薄层三氧化钨保护层，钨能与氟在室温下化合，红热并无潮气时能与溴、碘化合，红热时还能和水反应生成WO3，室温下钨可与王水反应，但热的浓盐酸和硫酸只能与其起微弱反应，但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应，高温下不能与碳、硼和硅反应生成二元化合物，工业上广泛使用钨钢和碳化钨，纯钨用来制灯丝、电子管和X射线管的发热元件，硅化钨可制半导体元件，钨工业生产是将白钨矿石或黑钨矿石精炼。
