选择适当的觇标类型，不断改进造标工作，对于大地测量工作的多快好省有着极为重要的意义。特别是对低标的选型、改进和重新设计的问题，是大家很关心的。在不同时期，不同地区，根据不同的材料来源，应该有符合实际情况的良好的觇标类型。总的来讲，这方面经验还不多。这里发表内蒙古自治区地质局测绘大队设计制造的“钻杆标”，他们充分利用了废钻杆制造寻常标，经过试验、改进、鉴定，正式用于生产取得了较好的效果，这是一件可喜的事情。有条件的单位都可以试用这个办法。这样不仅利用了废料，而且可以大量节约木材，减轻搬运，节约投资，一举数得。当然，也可以考虑和试验用其他有效办法，但须经过实践验证，并经有关部门鉴定后再推广。
Choosing the right type of bidding and continuously improving the bidding is of great importance to the generosity and speediness of geodesy. In particular, we are very much concerned about the selection, improvement and redesign of low standards. At different times and in different regions, depending on the source of the materials, there should be a good type of standard that meets the actual situation. In general, there is not much experience in this area. Here published Inner Mongolia Autonomous Region Geological Survey and Design Brigade design and manufacture of “drill rod standard”, they make full use of the ordinary production of waste drill pipe standard, after testing, improvement, identification, formally used in production has achieved good results, this is a Good thing. Conditional units can try this solution. This will not only use the waste, but also save a lot of wood, reduce handling, saving investment, a matter of course. Of course, you can also consider and test with other effective methods, but must be verified by the relevant departments and then promote the identification.
