The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.

结果表明：暴露于过大气的吸气剂表面覆盖着H2O、CO2及碳氢化合物等，Zr和V主要以氧化态存在；在吸气剂加热激活过程中，V的氧化物在200℃开始还原；激活过程导致表面近金属态Zr的富集以及部分金属碳化物的生成；随着温度的升高，H2O、CO2及碳氢化合物逐渐从吸气剂表面脱附，在200℃以上，主要脱附气体为H2，整个激活过程未发现O2；ZrO2还原为近金属态或金属态，主要是由于ZrO2中的O通过向吸气剂内部扩散而离开吸气剂表面所致。

CPT significantly inhibits the early stages of the Con A-induced T cell activation and proliferation, and detents the T lymphocytes in G0/G1 phase.

In addition,we give an explanation for the origin of the different conductive mechanisms in the insulating phase,i.e.,the variable range hopping originate from the energy gap produced by the dimerized Ir-Ir chains,while the thermal activation originate from the non-dimerized Ir.

另外，指出了CuIr_2S_4体系在低温绝缘相的导电机制，跃迁电导项来源于Ir-Ir二聚所产生的能隙，而热激活电导项来源于未二聚的Ir。

The results show that in the sintering process of clinker more La and Ce are distributed in the silicate phase, which form into solid solution with it ; The dopping effects of La and Ce induce the aberrance of stress field of diffusive medium, which decrease the activation energy of particles diffusing, and accelerate particles diffusing during the solid state reaction.

结果表明，稀土元素La和Y在熟料煅烧过程中更多地分布在硅酸盐相中形成固溶体；稀土离子的掺杂作用，导致扩散介质中应力场的畸变，降低了质点的扩散活化能，从而对固相反应中的质点扩散起促进作用。

Activation of the surface DORs causes a slow Ca〓 elevation by both inositol 1, 4, 5-trisphosphate receptor-mediated intracellular Ca〓 release and extracellular Ca〓 entry, resulting in a slow and long-lasting increase in intracellular Ca〓, exocytosis, DOR insertion and CGRP release.

激活DOR引起的DOR的上膜是依赖于LDCV与细胞膜的融合和细胞内的钙离子升高。激活DORs可以引起胞内IP3钙库的释放，和一种不通过电压依赖性钙通道的外钙内流；从而引起DOR的上膜和神经肽的分泌。
