建立了东天山地区古生代构造演化成矿格架,将该区镁铁质-超镁铁质岩体的分布新划分为7个带,四顶黑山发现寒武纪层状岩体,拓展了找矿空间。确认新近发现的卡拉塔格红山为上金下铜的“紫金山式”铜金矿床,成矿期为中生代,红山矿床氧化带中付针绿矾等7种矿物属国内首次发现。红山矿区中深部具寻找大型斑岩铜金矿的潜力,外围梅岭铜金矿区亦具有大型潜力。查明了白石泉—天宇镁铁质-超镁铁质岩体的期次与产状和空间形态。建立了图拉尔根铜镍矿区的构造格架,确定了含矿岩体的侧伏方向,浅层地震和大地电磁测深探查发现已知含矿岩体向深部变大,在北侧还发现了新的矿致异常。经两万米钻探验证,在预测区见矿厚度达50~260m,岩体延深加大(200m→800m)、延长变长(600m→1300m),规模已到大型。 The Paleozoic tectonic evolution mineralization framework was established in the East Tianshan area. The distribution of mafic-ultramafic rock mass in this area was divided into seven zones, and the Cambrian stratigraphic rock mass was found in the four Montenegro mountains. Mine space. It was confirmed that the newly discovered Calataghu Red Mountain is the “Purple Mountain Type” copper-gold deposit of Shangjixia Copper and the first discovery of seven minerals belonging to the Mesozoic and Oxalis in the oxidation zone of Hongshan deposit in China . The potential for finding large porphyry copper-gold deposits in the middle and deep parts of Hongshan Mining Area is also evident in the Hongshan Mining Area. Large-scale potential is also found in the outer Meiling copper-gold mining area. The occurrences and spatial patterns of the Baishiquan-Tianyu mafic-ultramafic rock mass were identified. The tectonic framework of the Tulargen copper-nickel mining area was established, and the side volt direction of the ore-bearing rock masses was determined. The shallow earthquakes and the geomagnetic sounding surveys found that the ore-bearing rock mass became larger toward the deep part and that on the north side Found a new mine induced abnormalities. After drilling for 20,000 meters, the thickness of the mine reaches 50-260 m in the prediction area, and the extension of the rock mass increases (200m → 800m) and lengthens and lengthens (600m → 1300m), reaching a large scale.

每年两会,“建议恢复繁体字”的提案都会刷屏,呼吁恢复繁体字的人认为,简体字导致了文化传统的断裂,令人痛心疾首。甚至有学者认为,废除繁体字,使年轻一代的历史感情和敬畏淡漠,与“文革”爆发有密切的逻辑联系。  虽然这些说法看上去很有道理,不过简体字并不是1949年之后才出现的,它的历史可能比大多数人想象得要漫长得多。  古代书法家很早就写简化字  支持繁体字的一个著名段子说,汉字简化之后,“親不见,愛
