第四三角队在进行较大面积的平原高级控制的选点工作中,曾取得了一些经验,现在提出来供同志们参考。 1.高杆大旗和竹质看标为了标志明显,根据黄河水利委员会的测量工作经验和我们在两个多月的实际工作,认为在平地村庄树林隐蔽地区,边长在15K M以下时,要用1M×1.5M面积的红白旗;边长在20KM左右时,就用2M×2.5M的大红白旗;如果边长近30KM时,标旗还得酌情增大,所用的旗杆的高度至少要超出周围一般树林5M以上。同时应注意绑旗时最好用细麻绳或棉索绑,如果用铅丝绑,就不能使铅丝头露在外面,因为旗下垂时会挂在铅丝头上飘不开,会减低它的作用。
The fourth triangle team has obtained some experience in the selection of high-level plain high-level control and is now proposed for reference by comrades. 1. In order to clearly mark the high pole banner and bamboo quality, according to the measurement work experience of the Yellow River Conservancy Commission and our practical work in more than two months, we believe that in the hidden areas of the plain villages and forests, when the side length is below 15K M, To use 1M × 1.5M area of the red and white flag; side length of 20KM, with 2M × 2.5M Dahongbaiqi; if the side length of nearly 30KM, the flag has to be increased as appropriate, the height of the flagpole used at least More than 5M above the surrounding general forest. At the same time, attention should be paid to the best use of fine hemp ropes or cotton ropes for the flag-binding. If lead wire is used, the lead wire should not be exposed on the outside, because its hanging time will hang on the wire head and will reduce its effect. .
