Actinolite and pyroxene phenocrysts separated respectively, from chlorite-actinolite schist and altered pillow basalt in the E'rou area of the eastern part of the Shuanghu-Longmuco suture zone, yield well-defined 40Ar/39Ar plateau ages of 235.9±2.6 Ma and 232.5±2.4 Ma. These nearly identical ages are interpreted as defining the age of the tectonothermal event of subduction-related collision along the Shuanghu-Longmuco suture zone.

在藏北龙木错－双湖缝合带东段双湖鄂柔地区，获得绿泥阳起石片岩中阳起石矿物的40Ar/39Ar坪年龄为(235.9±2.6)Ma和枕状玄武岩中蚀变辉石斑晶的40Ar/39Ar坪年龄为(232.5±2.4)Ma，两个年龄具有极好的一致性，记录了中三叠世晚期－晚三叠世早期沿龙木错－双湖缝合带发生俯冲碰撞作用的构造－热事件。

After filtration process, the results showed that the filtration effect of sewage was satisfactory. DTA and XRD patterns showed that the membrane calcined at 1000℃was composed ofγ- Al_2O_3, t -ZrO_2 and amorphism SiO_2, the phase transformation wasn't occurred until 1200℃.

DTA和XRD分析表明，经过1000℃煅烧后的复合膜中，主晶相为γ-Al_2O_3和t -ZrO_2，SiO_2以无定形态存在，复合膜经1200℃的热处理后仍然没有发生γ-Al_2O_3向α- Al_2O_3的相变。

Analytical results of differential scanning calorimetry DSC and X-ray diffraction XRD indicated that after compression molding,the melt temperature of PLLA crystals decreased while the degree of crystallinity increased.
