limiting loop
解釋
控制環-
Because of the absence of a limiting hernial sac, mechanical sbo usually occurs in cases of transmesenteric hernia ( fig 8 ), and it is impossible to differentiate closed - loop obstructions caused by herniation through the mesenteric defect from those caused by prolapse of the intestine under adhesive bands
由於後者沒有局限性的疝囊，機械性sbo通常發生在腸系膜疝的病例中（圖8 ） ，而且不能區分經腸系膜缺損疝導致的閉合性腸梗阻與粘連帶下的腸脫垂導致的閉合性腸梗阻。 -
Saturated sand are testes in the laboratory under the undrained cyclic loading condition with static - dynamic dual purpose triaxial compression test apparatus, which is designed under the cooperation of hohai university and marui co. ltd japan. the results indicate that the stress path approaches from a initial stress point to the failure lines as cyclic loading goes on, and eventually converges on a certain limiting stress path in the vicinity of the failure lines. the stress - strain curve, however, does not converge on a closed hystersis loop ; the shear strain rapidly increases in looser sand or gradually and continually increases in denser sand
利用河海大學與日本圓井株式會社共同研製的新型的多功能靜動三軸儀進行了飽和砂土循環扭剪不排水試驗，研究表明，對于松砂，剪應變幅度快速地由微小增加到百分之幾甚至百分之十幾，對于緊砂，剪應變幅度逐漸地由微小增加到百分之幾甚至百分之十幾；經試驗初步研究表明用初始有效平均正應力歸一化的有效應力路徑很好的一致性。
