We use in 316 steel pipes chromium content should after 16%-18% the steel joins elements and so on chromium, can change the steel the performance, like the example steel's molecular structure is evener, produces compact oxide compound protective film in the steel superficial change and so on, thus sharpens the stainless steel anti-corrosive ability greatly.

我们所使用的316钢管中铬的含量应该在16％-18％钢中加入铬等元素后，就能改变钢的性能，如例钢的分子结构更均匀，在钢的表面更易生成一层致密的氧化物保护膜等，从而大大提高耐腐蚀的能力。

Methods Three-dimensional gels of type I collagen containing rabbit keratocytes were incubated in the presence of different concentrations of exotoxin A (0.1,1.0,10 mg·L-1),cultivated for 24 h at 37℃, the change of keratocytes in morphology was observed under the light microscope,and the amount of lactate dehydrogenase was measured by enzyme linked immunosorbent assay.

To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.

研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。
