关于某个函数的参数

newfire201

函数：
db_add_t_nod_res_by_type( <num>, <rtid>, <rcid>, <layerids>, <nids>, <csys_type>, <cid>, <results> )
在帮助文档里，各参数的解释如下：

Input:
INTEGER	<num>	Number of nodes/results input.
INTEGER	<rtid>	Existing result type ID.
INTEGER	<rcid>	Existing result case ID.
INTEGER  ARRAY	<layerids>	(num) sized array of layer ID  for the result at each node.
INTEGER  ARRAY	<nids>	(num) sized array of node IDs.
INTEGER  ARRAY	<csys_type>	(num) sized array of coordinate  system types where: -1=Unknown, 0=Global, 1=Nodal, 2=Element, 3=User,  4=Material, 5=Ply, 6=On Edge, 7=On Curve, 8=Data Dependent.
INTEGER  ARRAY	<cid>	(num) sized array of CIDs  (csys_type=3).
REAL ARRAY	<results>	(num,6) sized array of tensor  results at each node/layer.
Output:
INTEGER	<Return Value>	This function returns a value of  0 when executed successfully and a non zero value to indicate a change in  status or an error.

但我不明白nids与cid是什么意思，怎么用啊？解释也看不懂

nids是节点ID的数组，cid是指当csys_type=3（用户坐标系）时坐标系ID的数组。
