中文拼音 [pòlièwō]
破裂窩
英文
lacerate fossae-
The following conclusions are gained : ( 1 ) the located shear band prongs the ligament near the top crack tip and the structure may occur shear - mode fracture at the angle of 155 ? to crack when load is 87. 92mpa ; the mode of fracture of the flange joint structure is not possible to be void - mode ; ( 2 ) it is proved that loading and then unloading repeatedly can not increase the possibility of invalidation of the structure when the times of loading and unloading are not too more when load is operating pressure ; the structure is safe when the vessel is operating ; ( 3 ) in the fe model of the thesis, not considering the influence of water pressure test which is in the process of fabrication of vessel in fe results in larger deviation in analysi
得出了以下結論：在8792mpa的載荷下筒體一封頭連接結構處的集中剪切帶貫穿韌帶，可能發生沿與原裂紋線成155 「角方向剪切型斷裂；筒體一封頭連接結構不可能發生韌窩型斷裂； （ 2 ）在工作壓力下進行次數不多的反復加、卸載，結構不會破壞，也不會喪失安定性：結構在工作狀態下是安全的； m在本文的彈塑性有限元模擬計算中，對于裂紋尖端進行力學分析時，不考慮壓力容器製造過程中水壓試驗的影響，將導致計算結果出現較大的偏差； （ 4 ）筒體完全屈服時的載荷為92石3mpa ，封頭完全屈服時載荷為86Conclusion ( 1 ) depending on location ， size and invading extension of the tumor ， above different approaches are adapted selectively which can provide excellent exposure and allow for an aggressive resection of the tumor. ( 2 ) the tumor tissue of the cavenous sinus and foramen lacerum is resected carefully by microsurgery. ( 3 ) the dural deficiecy must be repaired and sutured tightly to avoid craniocerebral fluid leak
結論（ 1 ）前或和中顱凹底內外溝通性腫瘤應根據腫瘤大小、位置及侵犯范圍選擇顱面聯合入路、額顳-顳下窩入路或額顳-顳下窩入路結合面前徑路即可給于充分暴露並能在直視下廣泛切除腫瘤； （ 2 ）中顱凹底侵及海綿竇和破裂孔部的腫瘤應在較高放大倍數手術顯微鏡下仔細分離切除； （ 3 ）硬膜的嚴密修復是避免腦脊液漏及顱內感染的重要關鍵。Experimental results indicated that the polypropylene fiber can improve the workability of concrete availably, and can increase the presentation quality of structures with the voids and pits decreased ; the cracks of beam are controlled effectively, the width and length of crack decreased, the dispersibility of crack in beam face improved, and the ductility of beam increased ; and the cracking load of reinforced concrete beam is increased, the amplify up to about 30 %, simultaneity the ultimate bear capacity increased
試驗研究表明，使用聚丙烯纖維后，能有效改善新拌混凝土的和易性，並能增強混凝土構件的外觀質量，減少構件表面蜂窩、麻面、氣孔、細小裂紋等；同時，在破壞試驗過程中發現梁的裂縫能得到有效控制，裂縫寬度減小，裂縫的發展高度降低，裂縫的條數增加，提高了梁截面的裂縫分散能力，增強了梁中混凝土的韌性；提高了鋼筋混凝土梁的開裂荷載，幅度可達30左右，增強了結構的延性，提高了結構的抗裂性能和屈服荷載。In our country, most of bridges were built in 1960s or 1970s, which were based on that time traffic discharge and development planning, so design criterion of these bridges were very lower. in addition, it was inevitable to bring about cracks > concrete rupture, steel rust ^ honeycomb and water proof layer failure, because some established bridges were built by poor construction and maintenance during the course of operating period. all above mentioned lead to durability and bearing capacity could n ' t gain to design standard
由於我國很多橋梁建於上個世紀六、七十年代，基於當時的車流量和各方面的發展規劃，橋梁設計等級普遍偏低；另外，某些既有橋梁由於施工質量差和運營期間維護不到位，不可避免地會產生裂縫、混凝土破損、鋼筋銹蝕、蜂窩及防水層失效等缺陷，從而導致耐久性及承載力達不到設計要求。分享友人
