短毫米波和亚毫米波接收机的发展现状

The specific property of atmospheric transmission at near submillimeter band is studied.

主要研究了在近亚毫米波段的大气传输特性。

During failover, one of the children becomes the master node and all replication starts flowing from that node.

在故障恢复过程中，其中一个子节点会成为主节点，而所有复制将从该节点开始。

You should now have all the components necessary to handle a failure of the master node, if it should occur.

现在您就已经拥有了处理主节点故障（如果它会发生）所需要的所有组成部分。

In clustered environments, probes are installed on all nodes, and each probe is configured as though that node is the primary node.

在集群环境中，探测器安装在所有节点上，每个探测器的配置方式都与主节点相同。

The --master option (-M) requires you to specify the master node where the master table dictionary is located.

master选项（-M）要求指定主表字典所在的主节点。

This example presents a simple HA cluster that consists of three nodes: a master node, a backup node, and a management node.

本例描述了一个简单的HA集群，由三个节点构成：一个主节点，一个备份节点，以及一个管理节点。

After you create a team project, you can manage and track work through the main nodes that were created for your team project.

创建团队项目后，可以通过为团队项目创建的主节点管理和跟踪工作。

The basic idea is to temporarily convert the nodes into a Linux system and from there they join the master node as member of a cluster.

其基本思想是将节点临时转换为Linux系统，然后作为集群的成员连接到主节点。

There can be up to 7 servers in a cluster, and any node can be the primary node.

一个集群最多可以支持7个服务器，并且任意节点都可以是主节点。

It is assumed that the Hadoop slave node has been configured a priori in such a manner that it registers with the Hadoop master node.

这里假设Hadoop从节点已经在之前配置完成，也就是它已经注册到Hadoop主节点中。

The storage server is connected to the master and backup nodes with a high speed myrinet or fibre-channel connection, as shown in Figure 2.

存储服务器通过高速myrinet或者光通道连接到主节点和备份节点，如图2所示。

The current emission was very stable at the pressure of 10-8 Torr. The drift was less than 2.5%.

在真空度为10-8Torr时，能得到较为稳定的发射，30min内发射电流的漂移在2.5%以下。

The measured optimum partial pressure of N2+ was 2.4 torr at a total pressure of 2 atm. in He/ N2 mixture. Kinetics of formation and quenching are analysed and discussed.

在He-N2混合系统中，总气压为2大气压时，测得最佳N2分压力2.4托，并讨论和分析了N2~+的形成和猝灭动力学。

The application of that new multiplier in extremely high vacuum measurements provides possibility on solving the measuring problem of 10~ (-13)~ 10~ ( 15) torr.

新型倍增器在极高真空测量中的应用，为解决10~（-13）～10~（15）托的测量难题提供了新的可能。

Vacuum degree of 1.2 × 10 7 Pa ( about 9.0 × 10 10 Torr) can be kept. It can meet the requirements of magneto optical trap operating in a vapor cell of Cesium atoms.

整个系统结构紧凑、性能稳定、操作方便，其真空度可保持在1.2×10－7Pa（约9.0×10－10Torr）左右，可满足直接工作在铯原子汽室中的磁光阱的要求。

By using Helium as test gas, the calibrations of ionization gauges were carried out within the range from 10~ (-3) to 10~ (-6) Torr and showed a good reproducibility.

用氦气作试验气体，在10~（-3）～10~（-6）托范围内进行校准，重复性良好。

Specifications Temperature: 173K 1073K continuously adjustable, accuracy ± 0.5 2K, Pressure: atmosphere to 10 MPa, Vacuum: 10 6 torr, Phases: gas solid and liquid.

性能指标温度：从173K－1073K连续可调，精度±0.5－2K；压力：常压至10MPa.真空度：10－6tor：相态：气固相及液相。

No,. 200 torr at the same temperature.

不是，25。200torr，在相同的温度下。

The vacuum box is outside of the optical box, can keep good vacuum at a level of 10-6 Torr. The vacuum box, vacuum pump and a refrigerator are composed of the cooling system of the camera.

光学箱外部是真空箱，是整个系统的机械支撑，保证良好的真空密封性能，和真空泵、冷冻机一起构成了相机的致冷系统。
