In order to accurately describe the model we have introduced the following model A: pixel coordinate system B: image coordinate system C: camera coordinate system D: world coordinate system

The guiding coordinate system for setting the axes is the left hand coordinate system.

The values set in the G54 are ( ). A: Origin of workpiece coordinate system B: Offset of origin of workpiece coordinate system relative to origin of machine tool coordinate system C: Length deviation value of tool D: Offset of workpiece coordinate system origin relative to tool alignment point

The spatial dimension of an urban transportation system includes:

From this tower, people involved in air traffic control coordinate aircraft movement both in the air and on the ground. A: cooperation B: cooperate C: coordinate D: coordination

Which procedure is recommended to prevent or overcome spatial disorientation? （ ）

Which of the following statements is wrong about curl? A: The curl of a vector field is a scalar and a function of the spatial coordinate points. B: At a certain point M in the field,[img=84x28]1803b721c59068a.png[/img] means that the vector line of this point is spinning. C: At a certain point M in the field,[img=84x26]1803b721cd97fe6.png[/img] means that the vector line of this point is spinless. D: Curl have the dimension of circumferential area density.

The chronological order means arranging information according to the spatial sequence.

Chronological order and spatial order are especially useful in informative speeches.
