衰减

Through establishing the priori estimates for the approximation solutions, we pove the existence of global generalized solution by using the compactness principle and obtain the global property for the generalized solutions in the space L〓. At the last, a new method is used to prove the uniqneness which is a good results, at some extense, under generalize conditions.

运用De Giorgi的最大模估计方法，证明了解的整体上界估计和准衰减型的估计，进一步，在边值和初值具有正的下界条件下，证明了解的一致下界估计，得到了深刻结果。

And the ex-perimental result shows that the decay time can be extended by exter...

由实验结果可以看出外加电场使衰减时间略有延长。

The composite analysis of the 5 major ENSO events since 1980's show that, through the meridional wind anomaly, the extratropical atmospheric disturbances play a role in triggering the occurrence as well as in the development and decay of ENSO.

合成分析了20世纪80年代以来5次主要的ENSO事件，发现外热带大气扰动通过经向风异常不仅对ENSO的发生起到重要的触发作用，而且影响到ENSO的发展和衰减。

"We have found that the power of the male heart falls by 20-25 per cent between 18 and 70 years of age," Professor Goldspink said.

葛兹平克教授说：我们已经发现男性在18到70岁之间心脏活力会衰减20%至25%。

Based on a simulation of asphalt mixtures' grade,asphalt binder content and air void in factual construction conditions,asphalt mixture samples at various segregation levels are obtained by gyratory testing machine,then integrated performances of asphalt mixture are tested.

在室内模拟试验中，考虑施工时混合料级配、用油量、空隙率等关键指标的变异性，采用旋转压实成型试件，定量测试真实离析水平下材料性能衰减程度。

The infrared spectra indicate that polyurea microcapsules have been successfully synthesized;all the TG thermographs show microcapsules containing n- hexadecane can sustain high temperature about 300 ℃ without broken and the DSC measurements display that all samples possess a moderate heat of phase transition; thermal cyclic tests show that the encapsulated paraffin kept its energy storage capacity even after 50 cycles of operation.

红外谱图显示合成了聚脲微胶囊，热重曲线表明含正十六烷的聚脲微胶囊能够耐受大约 300 ℃高温，差示扫描量热测试表明所有样品均具有合适的相转变热，冷热循环实验揭示微胶囊能够维持储热容量不衰减。

The spatial variation of seismic ground motions include the influences of the three factors of geometric incoherency effect,wave-passage effect,and local site effect.

引起地震动空间变化的原因主要是由地震波传播时的行波效应、相干效应、衰减效应和场地效应引起。

On the other hand, the grazing would also weaken the regrowth of some shrubs which had the higher content of crude protein such as Indigofera inchangensis Craib and Dalbergia hupeana Hance., so the grazing intensity to make these shrubs not to decrease even disappear in the shrubby commnuity should be carefully controled.

而对于某些粗蛋白质含量较高的灌木种，如宜昌木兰和黄檀等，放牧会影响其再生，故应严格控制其放牧强度才不致使其从灌木群落中衰减甚至消失。

There were five kinds of NpCpTiCl〓, in which Np was pyrolyl , indolyl ; 7-azoindolyl , indazolyl , and benzimidazolyl respectively. All of them were prepared by the reactions of CpTiCl〓 with the anions of the relevant ligands, and characterized by elemental analysis, IR, or NMR.

此外，半茂体系的催化活性都随铝／钛比的增加呈上升而后衰减型，当Al／Ti比为500左右时活性达到最高，这个值远低于茂金属催化剂活性达最高时的Al／Ti比，即茂金属配合物比半茂配合物需要更多的MAO来活化，并稳定形成的活性中心。

Twelve tumors were solid and three contained cystic components. Nine were inhomogeneously hypoechoic. Two were homogeneously hypoechoic. Two were inhomogeneously isoechoic. Two were homogeneously isoechoic. Two contained microcalcification. One with acoustic shadowing. Twelve were well-defined and three were ill-defined. Fourteen were regular and one was irregular. Four had acoustic halo. Six were ecstatic. Nine were not ecstatic. Thirteen were examined with color Doppler ultrasound. Nine had abundent branched blood flow within the tumor and ring blood flow around. Two had short linear blood flow within the tumor and ring flow around.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
