Silver accessories are not actually the argentiferous quantity 100%, that is because joins in the pure silver 7.5% alloy, let the silver the gloss, brightness and degree of hardness have the improvement.

它与9.999银有所不同，因为9.999银的纯度比较高，非常柔软难以做成复杂多样的饰品，而925银能做到。925银饰品其实并不是含银量100%，那是因为在纯银中加入的7.5%的合金，让银的光泽、亮度和硬度都有所改善。

Results: The light microscope pictures of group A(no ［α-32P］ ATP in the perfusate) showed that there was no specially labeled silver pellet in or out of rat liver cell.

The major thermal decomposition products are silver nanoparticles and behenic acid. The gas products from thermal decomposition of silver behenate were detected by MS. Carbon dioxide was first emerged, subsequently water, hydrogen, acetylene and some small molecule alkenes appeared.

采用MS对山嵛酸银在整个热分解过程中所释放出的气体产物的跟踪检测发现，首先是二氧化碳气体的放出，接着是氢气和水，随着温度的进一步升高，又伴随着乙炔和一些小分子的烯烃产生，当温度进一步升高到500℃左右时，被山嵛酸钝化的银纳米粒子逐渐失去了有机分子，最终的热分解产物为金属银。

The thermal behavior of silver behenate has been studied by infrared spectroscopy, X-ray diffraction, combined thermogravimetry-differential thermal analysis-mass spectrometry. The results indicated that complicated phase transitions took place while heating silver behenate,but there were two distinct thermal transitions. During the first transition at 138°C, the alkyl chains of silver behenate were transformed from an ordered into disordered state.

通过采用粉末X射线衍射、红外光谱、热重-差热分析与质谱联用技术，对山嵛酸银纳米晶体的热行为研究发现，山嵛酸银受热发生了一系列相转变，它有两个明显的突变：即在138℃左右，山嵛酸银的烷基链从高度有序转变为无序状态；在231℃左右，山嵛酸银发生了热分解，其主要分解产物为银纳米粒子和山嵛酸。

The effect of zeolites ion-exchanged by transition metals on thermal catalytic cracking reaction is studied. The product distributions of the cracking reactions catalyzed by theβor ZSM-5 zeolites exchanged with transition metals are different from that catalyzed by corresponding Hzeolites, which means the mechanism of cracking reactions has varied. Group Ⅷ metals Fe, Co, Ni and Cu, Zn are shown to be of strong catalytic activity of oxidative dehydrogenation, while Ti and Cr are not of oxidative activity. Catalyzed by zeolites or catalyst containing Ag, conversion of thermal catalytic cracking reactions and the yield of ethylene increase while the yield of propylene does not decrease. Silver can not only promote the formation of carbonium ion, but also convert carbonium ion into free-radical via redox reaction. The weak adsorption of olefins on silver reduces the occurrence of hydrogen transfer and dehydrogenation. As a result, the yield of light olefins is favored by silver in the catalyst.

采用过渡金属交换的分子筛作为催化剂，进行催化热裂解制取乙烯的反应，研究发现，在β沸石分子筛和ZSM-5分子筛中引入过渡金属后，催化热裂解反应的产物分布与相应的氢型分子筛相比有了较大的变化，说明过渡金属的加入对于催化热裂解反应的机理具有影响，Ⅷ族金属如Fe、Co、Ni和第Ⅰ、Ⅱ副族Cu、Zn表现出较强的氧化脱氢活性，产物中氢气、焦炭的产率很高，Ti、Cr则未表现出氧化作用：分子筛及催化剂中引入银后，催化热裂解反应的转化率和乙烯的产率有了提高，丙烯产率没有很大的变化，说明银在催化热裂解反应中能够促进正碳离子的生成，又有可能通过氧化-还原作用部分改变反应机理，促进了自由基的生成，并且由于银对烯烃的吸附很弱，其氢转移反应和脱氢、加氢活性比较低，有利于烯烃产率的提高。

Investigation of silver minerals in these ore deposits shows that the silver-bearing tetrahedrite and freibergite are among the most important or main industrial silver minerals.
