除了通过金属连接造成的传导性干扰，地网导体上的电流在电缆上产生的辐射干扰也在文中有所分析。

Doping Cr into perfect TiO2 (110) surface can create the new active surface state different from that of oxygen defect surface ,AM and transition metals deposited TiO2 (110) surface. Its active surface state is the Cr 3d occupied state near EF and the value of band-gap drop from 3.13eV to 1.16eV, so photocatalysis reaction can perform in visual light area after doping Cr into perfect TiO2 (110) surface.

TiO_2(110)面掺杂Cr 可以产生不同于氧缺陷、碱金属及过渡金属负载的新表面态，其表面态为靠近E_F 的Cr3d 电子占据能带，带隙由原来的3.13ev 降至1.16eV，因此，掺Cr 后TiO_2 可在可见光区发生光催化作用。

SCE on second order differential oscillogram, and the height of this pair peak of β-CD on the oscillogram decreased with the increase of Cu(superscript 2+) or rutin, phenobarbital, L-plenylalanine and amantadine hydrochloride concentration.

SCE处产生一对可逆、灵敏的峰，当加入Cu(上标 2+)、芦丁、苯巴比妥、L-苯丙氨酸、盐酸金刚烷胺等金属离子或有机物时，β-CD的二次微分示波图上的峰高降低。

To provide a theoretic reference for anti-adversity moriculture, we investigated the synergistic effects of H2O2 and Fe(superscript 2+), Cu(superscript 2+), Zn(superscript 2+) on free radicals damage and activities of protective enzymes in the leaf discs of mulberry in this paper.

研究了H2O2与Fe(上标 2+)等金属离子产生的自由基胁迫对桑树生理特性的影响，旨在为桑树的抗逆栽培提供理论参考。

By analyzing the behavior of metallic surface plasmon wave, the resonance condition and origin of frustrated total reflection are got.

分析了金属表面等离激元波的行为，得到了等离激元波与入射电磁波的共振条件及受抑全反射的产生原因。

Normally some coarseness will happened after sandblast treated ,which help to enhance the adhesive power.

Metal separations, resulting from imperfections at the edges of the plate or skelp, parallel to the surface, which turn toward the ID or OD pipe surface when the edges are upset during welding.

由于钢板或管坯边缘存在的缺欠所产生的平行于对焊表面的金属分离，当焊接过程中对焊边顶锻时，这些缺欠超者管子内表面或外表面翘曲。

Metals of low electrical resistence will be different to spot weld, whereas those of high resistance,such as stainless will produce a spot weld readily.

所输送的焊条在焊点处熔化，低电阻的金属很难应用点焊，而高电阻的，比如说不锈钢，能够很容易地产生点焊。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
