田。Ciehang lizhun弱磁场基准(lowm典笋etic field pnl朋叮stan-d田d)利用亥姆霍兹线圈在较大的空间产生很均匀的标准磁场，其线圈常数由准确测量的线圈几何尺寸计算得到。 中国研制的亥姆霍兹线圈的骨架为O义幻~的石英管，用纯铜镀金(或无氧纯铜)导线绕制，分上、下两段，每段38匝。导线直径0.8~，娜距1~。两绕组中心平面的平均距离与其半径大致相等(对亥姆粗兹条件的偏离约为3~)。根据对线圈绕组几何尺寸的测量结果，计算线圈常数K为 K二2 .28 x 10一4(Tl^)石英骨架和绕组温度效应所决定的线圈常数的温度系数为 。‘=一7 .82 x 10一，ldeg当线圈内流过已知电流I(二IA)时，它所建立的标准场的磁感应强度为 B=天才由于亥姆霍兹线圈所建立的标准场很弱，受地磁场的影响很大，因而必须进行地磁补偿。流过线圈电流的不稳定度半小时内不大于1 x 10一“，在线圈中心点出复现磁场的标准误差小于1 x 10一6，年稳定度为10一‘量级，磁感应强度约为0.05mT一lmT。(陆祖良)
