Firstly, based on the two-hop nonregenerative relaying system, an equivalent channel gain model for the two-hop regenerative relaying system is induced. Afterwards, the overall transmit power is allocated to the subcarrier pairs using water-filling approach. Finally, the above conclusions are generalized to the multi-hop relaying system.

首先在2跳非再生中继方式基础上，推导并给出了2跳再生中继方式下的等效信道增益；然后利用注水定理在子载波对间进行功率分配；最后把上述结论推广到多跳中继系统中。

Above all, the optimum synthetic condition of the photoactive compound is that acetone/water (85:15, volume ratio) is applied as the solvent and Et3 N is applied as the catalyst.

得到合成感光剂的最优条件：丙酮和水作溶剂的体积比为85：15，三乙胺作催化剂。

The adsorption percentage of Agby CCTS was above 99% at pH 3.0 and Agcould be eluted from CCTS with 8 mL 0.5 moL/L hartshorn.The Agin water was preconcentrated with CCTS and was then determined by GFAAS.

研究结果表明：在pH 3.0时，CCTS对银的吸附率达99%以上，其饱和吸附量为0.6 mg/g；采用8 mL 0.5 moL/L的氨水可将吸附在CCTS上的银定量洗脱。

The results show that Pd (superscript 2+) combines with KBr and cetyl pyridinium bromide into a ternary ion association precipitate2(PdBr4) in the aqueous solutions, which floated above the surface of water phase with clear interface.

结果表明，在水溶液中，Pd(上标2+)与溴化钾、溴化十六烷基吡啶形成不溶于水的三元缔合物2(PdBr4)，此三元缔合物可浮于水相上层分成界面清晰的液－固两相。

From overburden layer s,semipervious layers above depression-cone level drainage consolidation,porous media(geo-formation) compression and water compression,the ground settlement mechanism is analysed during foundation pit dewatering.

从降落漏斗水位以上覆盖层、弱透水层的排水固结过程到多孔介质的压缩、水的压缩三方面分析了深井降水引起地面沉降的机理，得出降水引起地面沉降的压缩层厚度主要为降落漏斗水位以上降深范围内的覆盖层和弱透水层厚度的结论。

The stores and houses was most all old, shackly, dried up frame concerns that hadn't ever been painted; they was set up three or four foot above ground on stilts, so as to be out of reach of the water when the river was overflowed.

此外便是灰堆，破旧的鞋靴，破瓶子，破布头和用旧了的白铁器具。围墙是用各种板子拼凑的，在不同的时间里给钉牢的，歪歪斜斜，很不雅观。

The stores and houses was most all old, shackly, dried up frame concerns that hadn't ever been painted; they was set up three or four foot above ground on stilts, so as to be out of reach of the water when the river was overflowed.

所有商店、住家大多是干木头搭的房子，东倒西歪的，也没有刷过油漆。离地有三四英尺高，底下用木桩撑着，这样，大水漫过来时，房子不会进水。屋子四周都有小园子，不过上面仿佛没有栽什么东西，所以杂草丛生，只长些向日葵。

The micelle shape transformation of tert-octylpheny phenol polyethylene glycol ether (TX-100), sodium dodecyl benzene sulfonate and tetradecyl trimethyl ammonium bromide in heavy water solutions was studied by 1H nuclear magnetic resonance spectroscopy, including an NMR self-diffusion experiment. These experiments showed that the surfactants formed several shapes of micelles (spherical, ellipsoidal, and rodlike) at the respective concentrations which were far above their critical micelle concentration.

运用核磁共振一维氢谱和自扩散实验方法研究了聚乙烯乙二醇异辛酚醚(TX-100)、十二烷基苯磺酸钠和十四烷基三甲基溴化铵三种不同类型的表面活性剂在重水溶液中的胶束形状转变，发现它们在临界胶束浓度以上的各自相应浓度都有胶束形状的变化（由球状转变为椭球状或棒状）。

The experimental results indicated that the yield of 2,6-DMN can reach above 38%, when the usage of dimethylnaphthalene was 2g, the temperature reached 18℃, the reaction time was 2.5h, the mole ratio of water-free aluminum trioxide to dimethylnaphthalene was 0.8, the mole ratio of transmethylation agent tetramethylbenzene to dimethylnaphthalene was 1.0, the usage of methane trichloride was 15mL.

结果表明，2-甲基萘(2-MN)使用量为2g时，反应温度为18℃、时间为2.5h、n：n（2-甲基萘）=0.8、n：n（2-甲基萘）=1.0、二氯甲烷用量为15mL时，2，6-DMN的收率可达38%。

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。
