3. Rotor
(2) Vector diagrams of an induction machine as a particular case of a transformer The mutual induction flux Φm is defined by the value of the magnetizing current Im which is equal to the vector sum of the current 1 and the referred current . Neglecting the losses in the steel, it may be assumed that the flux =m is phase with the current m . Let us introduce into the discussion the fictitious fluxes 1 and 2 coinciding in phase with the currents 1 and 2 and proportional to these currents so that
3. Rotor
(1) mmf equation Since in an induction machine the stator and rotor mmfs F1 and F2 both rotate in space with the same speed and in the same direction, it may be assumed that they are stationary in respect to each other and, consequently, create a common rotating sine wave of mmf Fm.【9】The mmf sine wave in this case must be shifted in space in respect to the mmf F1 by an angle that makes the resultant mmf Fm sufficient for setting up the emf equilibrium of the main magnetic flux Φm necessary according to the conditions.

在资源分区方式中，操作系统预先决定把哪些资源分配给某个 用户计算使用，这种方法也称为静态分配，因为分配是在程序 执行前进行的。静态资源分配易于实现，但由于它不是从程序 的实际需要出发，而是根据程序预先提出的需求来做决定，所 以容易导致系统利用率下降。

5.1.1 Resource allocation and related functions
In the partitioned resource allocation approach, the OS decides on the resources to be allocated to a program based on the number of resources and the number of programs in the system. For example, an OS may decide that a program can be allocated 1 MB of memory, 2000 disk blocks and a monitor. Such a collection of resources is referred to as a partition. In effect, a set of partitions can be predefined in the system. The resource table can have an entry for each resource partition. When a new program is to be started, an available partition is allocated to it.

control the furnace. When the room temperature drops below a preset value, the thermostat switch closes turning on the furnace. Once the room temperature rises high enough, the switch opens turning off the furnace. The current through the switch provides a digital representation of the temperature variation: ON equals "too cold" while OFF equals "notion 1 Introduction
Fig.2-2 Components of a signal system
Section 1 Introduction
Many electrical signals derived from physical systems are obtained from devices called transducers. We have already encountered an example of an analog transducer, the thermocouple pair. It converts temperature difference (the physical variable) to a voltage (the electrical variable). Generally, a transducer is a device that converts a physical or mechanical variable to an equivalent voltage or current signal. Unlike the thermocouple example, however, most transducers require some form of electrical excitation to operate.
