在工程设计中,异步电动机的起动方式应首选全压起动,但由于各种条件限制实际使用中常常采用电抗器降压起动和自耦变压器降压起动方式。假如全压起动时起动电压即为标称电压Un,起动电流为Iq,起动转矩为Mq。电抗器降压起动时起动电压与标称电压之比为k。自耦变压器降压起动时,变压比即为起动电压与标称电压之比k。请分别回答采用电抗器和自耦起动方式的下列问题。自耦变压器降压起动时,起动电流的表达式为()。
A. kIq
B. Iq
C. k2IqIq/k
Your network consists of a single Active Directory domain. All domain controllers run Windows Server 2008 and are configured as DNS servers. A domain controller named DC1 has a standard primary zone for contoso,com. A domain controller named DC2 has a standard secondary zone for contoso,com. You need to ensure that the replication of the contoso,com zone is encrypted. You must not lose any zone data. What should you do()
A. On both servers, modify the interface that the DNS server listens on.
B. Convert the primary zone into an Active Directory-integrated zone. Delete the secondary zone.
Convert the primary zone into an Active Directory-integrated stub zone. Delete the secondary zone.
D. Configure the zone transfer settings of the standard primary zone. Modify the Master Servers lists on the secondary zone.
