KB Term:

CompositeUnitOfMeasure

这是由其他单位的复合函数所决定的 UnitsOfMeasure Class 的实例，当中的每一个可以是一个 CompositeUnitOfMeasure 或是一个 NonCompositeUnitOfMeasure。

Relationships
Parents	函数量	A FunctionQuantity is a PhysicalQuantity that is returned by a Function that maps from one or more instances of ConstantQuantity to another instance of ConstantQuantity. For example, the velocity of a particle would be represented by a FunctionQuantity relating values of time (which are instances of ConstantQuantity) to values of distance (also instances of ConstantQuantity). Note that all elements of the range of the Function corresponding to a FunctionQuantity have the same physical dimension as the FunctionQuantity itself.
	测量单位	A standard of measurement for some dimension. For example, the Meter is a UnitOfMeasure for the dimension of length, as is the Inch. There is no intrinsic property of a UnitOfMeasure that makes it primitive or fundamental, rather, a system of units (e.g. SystemeInternationalUnit) defines a set of orthogonal dimensions and assigns units for each.
Children	UnitOfArea	Every instance of this Class is a UnitOfMeasure that can be used with MeasureFn to form instances of AreaMeasure.
	UnitOfAtmosphericPressure	UnitOfAtmosphericPressure includes those instances of UnitOfMeasure used to measure atmospheric pressure (barometricPressure), e.g., InchMercury.
	UnitOfFrequency	Every instance of this Class is a UnitOfMeasure that can be used with MeasureFn to form instances of FrequencyMeasure.
	UnitOfVolume	Every instance of this Class is a UnitOfMeasure that can be used with MeasureFn to form instances of VolumeMeasure.
