应生产厂的迫切要求,本刊将《环形预应力混凝土电杆国家标准》和《环形钢筋混凝土电杆国家标准》审议稿提前分期发表,供生产厂参考。这两个标准是由建材、电力、铁道、邮电等四个系统经过三年来的大量调查研究、反复修改后提出来的,尚待审议并报送国家标准总局批准。 In response to the urgent requirements of the production plant, this publication publishes the deliberations of the “National Standard for Ring Prestressed Concrete Pole” and “National Standard for Circular Reinforced Concrete Pole Rods” in stages for reference by the manufacturer. These two standards were proposed by the four systems of building materials, electric power, railways, post and telecommunications, etc. after numerous investigations and studies and repeated amendments over the past three years. They have yet to be reviewed and submitted to the National Bureau of Standards for approval.
