By using a one-dimensional variational (1D-Var) method, relative humidity derived from GMS-5 multi-channel satellite images and from NOAA-14′s TIROS Operational Vertical Sounder radiances were corrected by 6-h RH forecasts of the MM5 meso-scale NWP model.

这两种反演资料分别是用统计反演法反演GMS-5静止气象卫星多通道遥感信息得到的GMS反演地球大气湿度，和用同步物理反演法反演NOAA-14极轨卫星的TOVS晴空测值所得的TOVS反演湿度。

By using a one-dimensional variational (1D-Var) method, relative humidity derived from GMS-5 multi-channel satellite images and from NOAA-14′s TIROS Operational Vertical Sounder radiances were corrected by 6-h RH forecasts of the MM5 meso-scale NWP model.

本文采用一维变分法，并将MM5模式的相对湿度6小时预报作为背景信息，对1998年6~7月两种卫星反演地球大气相对湿度资料进行偏差校正试验，以提高其精度。

It is only the sorbed water in this first 10 mm that is exchangeable to buffer the daily variation in RH. Further progress in exhibition space climate buffering must wait on the development of absorbent walls with a high exposed surface area.

关于更进一步的研究，博物馆展出空间的气候缓冲控制应当等待有了合适的具有高度吸附表面的吸附墙体材料后，才能考虑应用于博物馆。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。

The reason of RH-KTB system performance declining is analyzed. Not only owing to entry temperature, pressure, flux of water vapor and condenser's bad effect, extraction ability of vacuum pump declines but also there are leaks in vacuum system result in system performance declining.

对系统性能下降的原因进行了分析，水蒸汽的人口温度、压力、流量的变动及冷凝器的冷凝效果不佳而导致的真空泵抽气能力下降以及系统泄漏是导致系统性能下降的主要原因。

In the simulation, the effects of the snorkel diameter, circulation flow rate , lift gas flow rate, oxygen content, and vacuum vessel pressure were taken into account.

对RH真空精炼时的脱碳、脱氧、脱氮和脱氢过程进行了动态模拟研究，考察了浸渍管直径、循环流量、吹氩量、氧含量和真空度对脱碳和脱气过程的影响。

Not only in low or wide temperature condition but also in higher temperature, Pt-Rh/Ce-Zr-Sr/Al_2O_3 can show high specific surface area raio and excellent stability. It is considered as the best catalyst, which has a promising industry application prospects.
