The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.
GUS组织化学染色结果表明,在MPBQ MT启动子驱动下,报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达,且在茎、叶、种荚中表达量较高,而在根、花瓣和种子中则没有观察到GUS基因的表达,表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。

Theresults indicated that the initial desorption rate of As was higher than As, but thefinal desorption percentage of As was two times higher than As; that in therange of pH(6.5-8.5), the desorption of As was the lowest(pH=6.5),and thepercentage increased with the pH value increasing or deescalating, but for the As,thepercentage increased with the increase of pH; that the supersonic accelerated desoptionof arsenic and the final percentage was lower than non-supersonic; that on the conditionof UV-light ,in a word, it took negative effect to desorption The"reproduced process"has been used in the procedure of regeneration.
实验结果表明,初始阶段,三价砷的脱附率高于五价砷,但最终脱附率三价砷低于五价砷;三价砷、五价砷在不同温度下的脱附实验表明三价砷的最佳脱附温度低于五价砷的最佳脱附温度;在pH=5.5-8.5时,随着pH的增大,五价砷的脱附率具有先减小再增大的趋势,在pH为6.5时脱附率降至最小;在pH=5.5-8.5时,三价砷的脱附率随pH的增大而增大;不论是三价砷还是五价砷的脱附过程,超声波条件都会促进脱附速率(来源:ecABC论a4文网www.abclunwen.com)的增加,并且最终的脱附率要高于无超声波条件下的脱附率;紫外光照条件下,随着光照时间的增加,两种价态砷的脱附率会达到一个较高的值,再降低。总体而言,紫外光照的存在不利于脱附的进行。

The results show that although both Ni substitution and Mg vacancies are effective in desorbing hydrogen at lower temperatures, the substitution of Ni at the Mg site is energetically more favorable than the formation of Mg vacancies. The Ni atoms of NiF2 can replace some Mg atoms of MgH2 systems, the reaction of NiF2+3MgH2=MgF2+Mg2NiH4 during mill process is accelerated, thus, MgH2 with the higher stability can be changed into Mg2NiH4. Because of a ternary hydride Mg2NiH4 with lower stability forming, the dehydrogenating properties on Ni doped MgH2 systems are improved.
结果表明:Ni替代Mg和创造Mg空位对MgH2体系解氢而言,均发挥有益作用,而形成Mg空位所需能量(6.51 eV)高于Ni替代Mg所需能量(2.12 eV),表明低温下Ni替代Mg对MgH2体系解氢而言更有利,至此NiF2中的Ni替代MgH2中的Mg,有利于加速化学反应NiF2+3MgH2=MgF2+Mg2NiH4向右进行,使结构稳定的MgH2发生转变,生成结构不稳定的Mg2NiH4,这样体系解氢过程不是通过MgH2,而是转变为通过Mg2NiH4进行,因此,Ni掺杂提高了MgH2体系的解氢性能。

When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires. The coercivity of the Fe nanowire arrays in the diameter of 16nm is 2000Oe at 300K, and it will increase to 2800Oe when the temperature decreases to 5K.
不同直径的Fe纳米线的磁滞回线均表明沿着线的方向均表现出shearing effect,表明其中存在一个等效退磁场,它来源于线间的偶极相互作用。16m的Fe纳米线的矫顽力室温下为2000Oe,5K时则达到2800Oe。
