weak strain
解釋
生命力弱的菌株-
Finally, the stress and strain distributions of dam foundation in which there have glacis weak surfaces are studied by means of nonlinear fem. with deducing parameters of weak surfaces gradually, stability of the dam against deep sliding is verified. therefore safety of dam and foundation would be estimated
5 、運用非線性有限元法研究了東張水庫重力壩含有緩傾角軟弱夾層的壩基應力、應變情況，用逐步降低夾層材料參數的方法核算大壩的抗滑穩定，以此評價大壩及壩基的安全性。 -
The native expressed product from e. coli bl21 ( de3 ) strain, however, showed weak activity against tmv. gp609 and zwemu were inserted into pemu - mcs - n, an expression vector for monocotyledon. and rhxjb was inserted into pkylx71 : 35s2
將dna一8001連接到pet一sa表達載體上，在大腸桿菌blzi （ de3 ）菌株中實現天然表達，表達產物對tmv的抑制效果很差，其原因可能是c一末端延伸序列的存在抑制了抗tmv活性的發揮。 -
It is indicated in the test that the influence of loading to strain in the grout was about in the range of 5 ~ 6m, and very weak beyond 4m. the distributions of strain and bond stress in the grout are attenuated in the minus exponential rule
試驗結果表明，加載對錨固段內的應變影響范圍大致在5 6m左右， 4m以外很微弱；錨固段注漿體內的應變與粘結應力分佈按照負指數規律衰減。 -
In this paper, systematic numerical test have been carried out to study the stability of surrounding rock mass with different distribution of weak interbed, different distance between weak interbed and limit of excavation, different thickness of weak interbed, in the different confining coefficient and representational surrounding rock mass graded ii, iii, iv. all of the numerical modeling is plain - strain type with elastic - plastic constitutive law and mohor - coulomb failure criterion, through the integrated numerical analysis program final. plentiful numerical test results have been drawn via analyse the deformation, tensile stress region, plastic region of surrounding rock and the stress status of shot - crete
大量的工程實踐表明，軟弱夾層對地下洞室圍巖穩定性的影響有著決定性的作用，本文以大型數值模擬分析系統final為平臺，採用彈塑性應力應變關系和m - c屈服準則建立平面應變問題有限元模型，對軟弱夾層的分佈部位、分佈距離、軟弱夾層的厚度對圍巖穩定性的影響以及在具有不同側壓力系數的地應力場中和、 、類代表性圍巖中軟弱夾層對圍巖穩定性的影響進行了系統的數值試驗，研究得出了軟弱夾層對圍巖位移、拉應力區、塑性區以及噴射混凝土層內力等影響豐富的量化成果，以便直接為工程設計人員提供參考。
