The XRD data indicates that, Ag crystalloidal nanoparticles exist in the films as the annealing temperature above 300℃. As the contrast, non-crystalloidal Ag was found in the films annealed below 300℃. The AFM image of sample imply that, in the Ag layer was first prepared films, nanocomposite films consist of nanosized Ag particles embedded in MgF2 matrix.

Yeah,this right here goes to everyone that has last someone come on ,check it out seems like yesterday we used to rock i laced the frack you lock the flow so far hanging on the block for dough no'torious they got to know that life ain't always what it seems to be words can't express what you mean to me even though you're gone .we are still a leam through your family,i'll fulfill your dream in the future can't wait to see if you'll open up the gates for me reminiscence sometime ,the night they try to block it out ,but it plays again when its real feelings hard to conceal can't image all the pain i feel give anything to hear half your breath i know your still living your life after deathy every step i take, every move i make every single day, every time i pray i'll be missing you thinking of the day when you went away what a life to take what a band to break i'll be missing you i miss you b.i.g.

是的，就在这里去所有有最后一个来吧，看看看来我们昨天用于岩石我的frack浓黑的流动你锁定到目前为止，挂在那块面团没有'torious他们必须知道生活不总是似乎是什么不能用言语来表达你对我而言意味着什么即使你离去的时候，我们仍然是一个定义通过你的家人，我会实现你的梦想在未来等不及想看看如果你要为我打开大门有时，他们铭记试图阻止它，但它在脑中重现当它真正的感情就很难隐藏吗所有的痛苦无法形象时，我的感觉付出一切，只为再听到你的呼吸我知道你deathy后仍然生活我踏出的每一步，我的每一个举动每一天，每次我祷告我会想念你思想的一天当你走了吗什么是生活什么乐队来帮忙我会想念你我想你b.i.g。

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

实验结果显示：烧成的熟料溶出条件宽松，二次反应程度弱；溶出浆液在170℃左右直接进行加压脱硅，脱硅后溶液的硅量指数大于200，再加入适量的石灰进行深度脱硅，即使溶液中氧化铝浓度超过200g/L时，精液的硅量指数也大于600，且得到的水化石榴石中二氧化硅饱和系数大于0.28；通过加入晶种和采用新的碳酸化分解工艺制度，产品中的SiO2 含量降至0.025%， Na2O含量小于0.37%；加入表面活性剂，不仅能将碳分母液蒸发至Na2OT浓度大于300g/L，而且还可有效减缓表面上结疤的形成速度。
