  1. In this paper, the definitions of soil macropore and macropore flow, their types, characteristics, generation mechanisms, and experimental methods in laboratory and field were introduced, and the research progress in their determination techniques, including dye tracing, slice up penetration curve, tension infiltration apparatus, x - ray ct scanning, and radar exploration were summarized

    摘要介紹了大孔隙及大孔隙流的定義、多種表現形式及其重要特徵、產生機理和室內外實驗研究概況，以及染色示蹤、切片、穿透曲線、張力入滲儀、 x射線ct掃描攝像和雷達探測等方法的研究進展，揭示這些實驗方法的優點與存在的問題。
  2. That is, the partially penetrating sand drain ground is viewed as the double - layered ground, and its consolidation is analyzed with 1 - d consolidation theory, through the transformation from 3 - d consolidation to 1 - d consolidation in the region of sand drain. this can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under - lying soft layer. to the double - layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory

    然後，在充分考慮豎井區井阻、塗抹作用以及土體結構損傷破壞對固結影響的基礎上，將未打穿豎井地基合理地轉化為雙層地基，按一維固結理論計算，克服了傳統固結計算方法在豎井處理區與下臥層交界面處存在孔壓間斷的缺點；在此基礎上，從超載預壓法的基本原理出發，分析了雙層地基超載預壓固結、沉降機理，推導了多級等速加、卸載情況下雙層地基的固結計算公式，進一步完善了雙層地基固結理論。
  3. The result, two years of r & d on, is a launch collection of six styles, each made from japanese steel, each with patent - pending and each dispensing with anything extraneous to focus on assorted new mechanisms : a flat bar with sections that open out to keep it in place once passed through the button - holes ; an s - bend that swivels to lock into a square shape ; and, most radically, a cufflink with a twist mechanism that, rather than pull the two ends of a shirt - cuff together, creates a space between them, making room for an outsized watch

    經過兩年的研發，該公司的成果是發布了一個由6種款式組成的系列，每種款式都由日本鋼鐵製造，每種都將申請專利，每種都省去了無關的設計、將重點放在各式各樣的新裝置上：一塊扁鋼條，上面附有向外張開的部件，使袖扣穿過紐扣孔后就能固定住；能夠旋轉的s型彎曲，可以固定進一個正方形的外形中；更為激進的是，一款具有扭曲設計的袖扣不是將襯衫兩端連接在一起，而是在它們之間創造出一定空間，為一隻特大號手錶留出了地方。
  4. Subassemblage and prestressed concrete frames are assembled by precast prestressed beams and columns with tendons in the joints of the frames. these beams and columns are hoisted in site and the tendons are passed through the moire pipes. so prestressing force are brought to the joints of the frame. these tendons also can assume the moments at the end of the beams in ordinary condition

    預壓裝配式預應力混凝土框架是採用工廠化生產的預制柱和預制預應力梁，運至現場直接吊裝，樑柱就位后，將后張預應力筋穿過樑柱預留孔道，對節點實施預應力張拉預壓。
