  1. Pass through mechanical model calculate, discover the vault and arch foot part in the tunnel secondary lining thickness is weakness part, so at the design and construction must strengthen these part

    通過力學模型計算,結構在拱腳與仰拱交接處以及拱頂部位為隧道二次襯砌混凝土結構的薄弱部位,設計和施工時應著重加強。
  2. Past investigation found the rock in the right dam foundation composing of granite ( _ 4 ~ 3 _ 5 ~ 1 ) in dyas - trias, which has a very complicated mechanical environment. the complicated phenomenon is as follows : tectonism, alteration, rock mass demobilize, rock mass stress release and other factors. because of this several weakness rock zones and a loosen rock mass zone are develop in the right dam foundation

    前期的調查表明其右岸巖體力學環境復雜,表現為:構成右岸壩基(肩)巖體主體的二迭三迭紀花崗巖( _ 4 ~ 3 _ 5 ~ 1 )受構造變動、蝕變、風化卸荷等因素的影響形成了壩基軟弱巖帶和壩肩上部卸荷鬆弛巖體。
  3. The influence that the zr / ti ratios have on the ceramic crystal structure and its properties are studied through the research carried out about the relative respects of the fabricated samples. the increase of zr / ti ratio can result in the crystal structure transformation from the tetragonal to the rhombohedral, it can also induce the weakness in the stability of the ceramic crystal structure, for example, the drop in the curie temperature. in order to enhance the relative low mechanical quality factor of pzn - pzt system piezoceramics, component addition pb ( mn1 / 3sb2 / 3 ) o3 ( hereafter abbreviated as pms ) are introduced in to form a new psudo - tetragonal system ceramics

    為獲得具有高的機電耦合系數kp ,高的機械品質因數qm的高性能壓電陶瓷,採用二次合成法制備了不同zr ti比的鈮鋅酸鉛-鋯鈦酸鉛基( pzn - pzt )三元系壓電陶瓷材料,研究了zr ti比變化對陶瓷結構和性能的影響規律,發現zr ti比增大除了可以使陶瓷的相結構由四方相向三方相轉化外,還降低了陶瓷的結構的穩定性,使tc溫度下降。
  4. Theuhmwpe fiber has the high strength and high modulus characteristics, and the other mechanical properties are as well more outstanding, so the uhmwpe fiber gets the extensive application development in the each realm, particularly in the military protection realm. but the uhmwpe fiber exsits surfacial nonreactivity, with the weakness of the poor adhesion ability with the other materials

    超高分子量聚乙烯( uhmwpe )纖維具有高模、高強的特性,其他機械性能亦比較突出,故uhmwpe纖維在各個領域尤其在軍事防護領域得到日益廣泛的應用。但是, uhmwpe纖維存在表面惰性,與其他材料的粘合能力差的缺點。
