Slip, , is defined as the difference between synchronous speed and operating speed, at the same frequency, expressed in rpm or in percent or ratio of synchronous speed. Thus
Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.
1)Synchronous motors are those that run only at Synchronous speed i.e. constant speed. But Motor can run in various speeds. 2)Synchronous motors runs at same speed of magnetic filed. but if one consider case of induction motor the rotor rotates at different speed than revolving magnetic field. there is slip between field and rotor.

Checked Stephen J. Chapman's Electric Machinery Fundamentals page 287. It says: Short Circuit Ratio (SCR) for the synchronous generator is the ratio of the field current required for the rated voltage at OPEN circuit to the field current require for the rated armature current at SHORT circuit.
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
Probably... What ratio? X/R? X0/X1? X0/R0? Xd /Xd''? etc.
Formula to calculate the ratio
Synchronous impedance is also known as the EMF method. It is a ratio of open circuits to short circuits, when they both are referred to the same field excitation.
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit

No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.
