The constant search for a more effective infantry weapon led in the 1990s to the concept of small - calibre high - explosive fragmentation grenade shells designed to burst over the heads of their targets, thereby permitting the attack of troops in defilade, ie hiding behind cover
源於上世紀八十年代的對更加有效的步兵武器的不斷研究得出了小口徑高爆破片手榴彈的外殼設計用於殺傷目標頭部的概念，從而形成了對隱藏於工事及掩體的部隊進行攻擊的手段。From studies of these characteristics of structures, palaeontology, drilling, well logging, seismic profile, salt chemistry and lacustrine sedimentary system, it is recognized that the new characteristics occur in of section pukou and in huaiyiri sag, and the huge thickness of salt rocks is formed by the crust salt materials upwelling along deep fracture in the form of hot bittern and entering lacustrine basin in this area
通過該區構造、古生物、鉆井、測井、地震、鹽巖化學及湖盆內沉積體系等特徵的研究，認為淮陰凹陷浦口組二段和三段的沉積構造有其特殊性，巨厚的鹽巖層是殼深部鹽類物質沿深大斷裂上涌以熱鹵水形式進入湖盆的結果。A port tyre crane has various parts and complex structure, which is made up plenty of beam - bar and shell elements, manual calculation can not guarantee the precision while finite element method needs onerous structure modeling and a great deal of date input. the finite element analysis and modeling of the port tyre crane are difficult because of complex structure and various loads. in order to fit further more design and exploitation of the same type as well as the upgrade of the production i study a kind of parametric software for structure analysis of the port tyre crane, it can reduce the difficulty of modeling and structure analysis as well as improve efficiency
港口輪胎式起重機部件繁多、結構復雜，由數目眾多的梁桿與板殼組成，其結構設計和力學分析使用傳統的手工計算方法難以保證精度，有限元方法則需要繁重的結構建模和大量的數據輸入，並且要求分析人員具有相當的力學知識和有限元基本理論。港口輪胎起重機結構的復雜性、載荷工況的多變性導致港口輪胎起重機結構有限元建模和分析工作效率低、難度大。針對這種情況本課題研發了一套港口輪胎式起重機結構的有限元參數化分析軟體，以適應同類機型的進一步設計開發和產品升級換代，降低建模和分析的工作難度，提高工作效率。Based on the studies of the " bedding " and " sedimentary relic " of granite in the proterozic strata at huangqikou of the middle part of helanshan, the authors think that the proterozoic granite in the area was produced by metasomatic metamorphism, which formed during the time when the earth crust became thinner
對賀蘭山中段黃旗口元古代地層中存在於花崗巖中「層理」 、 「殘留體」等地質現象進行研究，認為該地區花崗巖是由元古代沉積巖經過變質交代作用而形成的，這種變質交代作用可能發生在古元古代，在秦祁賀三叉裂谷活動之前地殼變薄的大地構造環境下形成。分享友人
