| gen. | augmenting downstream flow | 下流域の流量増化 |
| gen. | constant downstream level gate | 下流定水位ゲート |
| radio | downstream chromakey | 後挿入クロマキー |
| comp., MS | downstream connection | ダウンストリーム接続 (A connection that enables a computer running Host Integration Server 2004 to support communication between a host and a client. Host Integration Server 2004 offers several types of downstream connection: 802.2 (Token Ring or Ethernet), SDLC, and X.25) |

| gen. | downstream facing | 下流表面工 |
| gen. | downstream fairing | ピア下流端 (of pier) |
| gen. | downstream fill | 下流側シェル |
| gen. | downstream lip of hood | フード放水口の外線 |
| comp., MS | downstream LU | ダウンストリーム LU (A logical unit (LU) used by a client to access a host connection through a computer running Host Integration Server 2004. A downstream LU uses a downstream connection, and passes information between the client and the host) |
| gen. | n downstream migration | 降河回遊 |
| gen. | downstream power increase | 下流出力増 |
| gen. | downstream region | 下流領域 |
| gen. | downstream regulated system | 下流調節システム |
| gen. | downstream regulation | 下流調節 |
| gen. | n downstream sector | 下流域 |
| gen. | downstream slope | 下流法下流面勾配、 かりゅうめんこうばい |
| gen. | downstream slope | 下流傾斜 |
| gen. | downstream slope | 下流斜面 |
| gen. | downstream slope | 下流面勾配 |
| comp., MS | downstream system | ダウンストリーム システム (A client, such as an IBM Communications Manager/2 system, that can access a host connection available on a computer running Host Integration Server 2004. Even though such a client does not use the Host Integration Server 2004 client/server interface, the client can use a downstream connection and a downstream LU to communicate with the host through Host Integration Server 2004. Host Integration Server 2004 passes the information between the downstream system and the host. With Host Integration Server 2004, a downstream system appears to the host as a logical unit, not a physical unit) |
