    摘要: This invention discloses a method of producing virus-free potato minitubers, which includes the steps of selecting virus-free test-tube plantlets and stem sections cut from seedlings grown 30 days after cuttage of such virus-free test-tube plantlets as cuttaging seedlings, choosing vermiculite as cuttage medium, treating the cuttaging seedlings with plant growth regulators, keeping the growth conditions of the cuttaging seedlings at 25.degree. C. during the daytime and 12.degree.-17.degree. C. at night, relative humidity 95-100% during the early stage and 60-70% at the later stage, and a light duration of ten hours a day with illuminance of 400-600 lux, along with suitable field management of water and fertilizer. The virus-free potato minitubers can be harvested in 30 to 60 days.

    摘要: Methods, systems, and devices for wireless communication are described. A base station may determine a mapping configuration for antenna ports that includes mapping antenna ports with high spatial correlation to frequency resource and mapping antenna ports with low spatial correlation to time resources. The base station may apply a common coding mechanism to channel state information reference signals (CSI-RSs) having a timing domain and transmit the CSI-RSs using antenna ports with high frequency separation. A user equipment (UE) may receive the CSI-RS on the channel and identify a joint correlation metric based on a frequency correlation and a spatial correlation between CSI-RS and the channel. The UE may determine a channel estimate for the channel based on the joint correlation metric.

    摘要: A method, an apparatus and a system for migrating VPN Routing and Forwarding (VRF) instances are disclosed. The system includes: a first BGP process, configured to: send a VRF instance and configuration information of BGP peers in the VRF instance to a second Border Gateway Protocol (BGP) process; instruct a Transport Control Protocol (TCP) to back up a TCP link to the second BGP process in a hot backup mode, where the TCP link is related to peer sessions of the BGP peers in the VRF instance; and the second BGP process, configured to: receive routes in an Adjacent Ingress Routing Information Base (Adj-RIB-IN) sent by the first BGP process unit. In the embodiments of the present invention, BGP peers services of the VRF instance are not interrupted, and the sessions are not disconnected; a peer device cannot perceive the migration process of a router completely; and changed routing information in the migration process is updated after the migration.
