The carbon foam were prepared by self-bubbling at high pressure from AR pitch added sodium dodecyl benzene sulfonate and Span-40, respectively. The bulk density, pore rate, compressive strength, thermal conductivity at room temperature and crystallitic parameters of carbon foam were measured. The rheological properties of AR pitch and pore structure of carbon foam were investigated.

而后采用脱脂后水浴醇提的方式大量提取，结合大孔吸附树脂和硅胶柱层析

After SBF solution cultivation for some days, the Ca/P coating was very easily deposited on the porous surface that was constituted of cystiform polygon made up with irregular nanometer circles like honeycomb. The energy spectrum showed that n/n atom ratio is about 1.61:1 which is very similar to that of HA and human bone. The active surface of the porous titanium after acid-alkali treatment and SBF solution condition which calcium-phosphorus ions was supersaturated induced the formation of Ca/P deposition layer.

SBF溶液培养后发现沉积层由蜂巢状多边形胞状物组成，这些胞状物是由网状纳米环无规则排列构成，能谱测定钙、磷元素原子比n／n约为1.61∶1，与HA和人骨中的钙磷原子比很接近；通过对沉积机理的分析，认为微孔钛的活性表面和SBF溶液过饱和离子浓度的环境造成了液相中钙磷盐的沉积。

Methods: A bone pore and a large membrane flap of dacryocyst were made under endoscope, and the membrane flaps of dacryocyst and nasal cavity were sewed up and fixed to the deep surface of the inner canthus by selfmade needle in 42 patients (56 eyes) with chronic dacryocystitis.
