Targeted gene replacement (TGR) is an important technique for gene function analysis.

目标基因替换是基因功能分析的重要手段。

Sediment deposition in Three Gorges Reservoir (TGR) is likely to increase significantly after the filling of TGR.

三峡水库蓄水运用后，库区泥沙淤积将显著增加。

With the formation of the Three Gorges Reservoir Area (the TGR Area), the water quality of the TGR Area has also aroused public attention.

随着三峡库区的形成，三峡库区水环境的质量也引起了公众的注意。

With the completion of the Three-gorge Project (TGP), the residence time of the water body will be prolonged, and the eutrophication within TGR will be aggravated.

随着三峡工程的全面完工，库区内水体滞留时间的进一步延长，三峡库区水体富营养化趋势将会进一步加剧。

Non horizontal Multi Layer Finite Element Model is applied in this paper to simulate the flow and the concentration of Wanzhou Reach in The Three Gorges Reservoir(TGR).

本文采用斜分层有限元模型模拟了三峡水库蓄水前后万州江段的流速场和浓度场。
