After retrofitting, air-conditioning load of the building reduced 89% and energy consumption reduced 83.5%.

经过改造后，建筑的空调负荷下降了89%，年空调能耗下降了83.5%，改造结果达到了的预期目标。

There was difference of malnutrition reduction among different minority g roups of Yunnan. However, the NPA aim for malnutrition reduction had not realize d up to 2000. Conclusion: Malnutrition is still a serious health problem in rura l children in Yunnan.

2 0余年来云南省儿童体格发育呈增长趋势，农村5岁以下儿童营养不良呈下降趋势，但下降幅度未达到国家NPA目标，5岁以下儿童营养不良仍是云南省农村儿童的主要健康问题。

Research results indicated that the underground biomass changes of three species differed obviously under different traffic treatment. Poa pratensis and Zoysia japonica underground biomass increased at the light traffic then declined. 'Barlexas' Tall fescue decreased with increasing traffic stress. Obvious root shallowing phenomenon is displayed through the increase of roots percent in surface layer and decline in deep layer. Moreover, traffic made the soil density and hardness increase.

结果表明：践踏胁迫下，3种草坪草地下生物量变化表现出较大差异，草地早熟禾和日本结缕草先增加后下降，高羊茅一直呈下降趋势；3种草坪草表层根系（0~5cm）所占比重明显增加，深层根系所占比重减小，根系的表层化现象明显；研究还表明，践踏使表层土壤容重和硬度增加，物理性质恶化。

The results showed that as to resistant material (R15), the activities of POD, CAT, SOD, APX increased and PAL kept stable in sheaths, in leaves the activity of POD、CAT and APX increased, SOD、PAL decreased; as to high susceptible material (478), the activities of POD and CAT increased in both sheaths and leaves, SOD increased in leaves but decreased in sheathes, both PAL and APX had no striking change.

其结果显示高耐材料R15的叶鞘中除PAL变动不大外，POD、CAT、SOD和APX活性都有不同程度的增加，其中POD活性变化最为剧烈，叶片中POD、CAT和APX表现上升，SOD、PAL表现下降；高感材料478的POD、CAT在叶片与叶鞘中均表现上升，SOD在叶片中上升、叶鞘中下降，PAL和APX均无明显变化。

The content of Z+ZR rose obviously and descended rapidly before and when gall started on swelling, respectively. The content of IAA in leaves was descending from anaphase to telophase of gall's swelling. The content of ABA in leaves was raised just before gall's swelling and that in sheathes was raised in anaphase of the gall' swelling, but there's no visible change in culm. There was no obvious change of GA 3 content in all parts and during growth and development.

其中 Z+ZR 含量在肉质茎膨大前即已明显上升，膨大开始后显著下降； IAA 含量在肉质茎膨大后期至末期才出现下降；叶片内 ABA 含量在肉质茎膨大前即开始上升，叶鞘内 ABA 含量在肉质茎膨大后期上升，茎尖内则无明显变化；各部位 GA 3 含量在整个生育期内无明显变化。

That means that although the economy is spiralling down, it is doing so more slowly.

这意味着虽然经济正急剧下降，但其下降的速度开始放缓。

That means that although the economy is spiralling down, it is doing so more slowly.

这意味着尽管经济正在呈螺旋型下降，但这个下降正在变得比较缓慢。

Falls in imports are often even starker: China's were down by 21% in December; Vietnam's by 45% in January.

进口额的削减通常更严重：中国12月份下降了21%，越南1月份下降45%。

Falls in imports are often even starker: China's were down by 21% in December; Vietnam's by 45% in January.

十二月，中国进口额下降了21%，一月里越南下降了45%。

The distribution characteristics of permafrost in this area were described based on drilling investigation. With the increase of altitude, the seasonally frozen ground zone is subrogated by patchy permafrost zone and then by continuous permafrost zone.

多年冻土分布具有明显的高度地带性，随高度增加，冻土分布呈现出季节冻土－岛状冻土－连续冻土更替，同时，多年冻土下界高程与经度明显相关，自西向东表现出下降趋势，下降率约为每经度150m，这一变化与降水在东西方向的变化有关。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
