falling block
解釋
落下式閉鎖-
Roll over protective structure ( rops ) is a device which installs on out of construction vehicle. the main functions are : when the vehicle rolling over. rops can prevent the vehicle from rolling over further, and reduce the possibility of rolling vehicle injures operator ; when the vehicle traveling on freezing soil. concrete and rock, it has large resist continuous impact ability ; when the vehicle overturning rops can support the whole vehicle. arrangement of falling object protective structure ( fops ) can block objects ( such as trees, rocks ) so that supply protection for operator. this problem is that research rolling over and falling objects protective structure of bulldozer by learning research condition of rops / fops and relative lay down international standard. on the base of theory analysis. detrudes counting formula of rops / fops deformation through founding mechanics analysis model of rops / fops at the stage of elasticity and plastoelastic. and finds a set of feasible nonlinear finite element analysis counting. lt calculates rops / fops plastoelastic deforma variable of 320hp bulldozer, bulldozer has been carried out by optimizing design method
其主要功能是：當車輛滾翻時， rops能刺入未凍土壤而阻止車輛的進一步滾翻，降低滾翻的車輛對系著安全帶司機軋傷的可能性；保證rops在碰撞和沖擊變形不大的地面（如凍土、混疑土上、巖石）時，能具有相當大的抗連續沖擊能力；當車輛已經處于顛覆狀態時，已經變形的rops應能支撐住整車。落物保護裝置（簡稱fops ） ，其構件的布置方式要能遮蔽墜落的物體（如，樹木、巖石等） ，以便對司機提供適當的保護。本課題主要通過了解國內外有關對rops fops的研究情況和有關國際標準的制定，對大型推土機傾翻和落物保護裝置進行研究，在理論分析的基礎上，通過建立rops fops的力學分析模型，推導彈性、彈塑性階段rops fops變形的計算公式，建立一套可行的rops fops的非線性有限元分析計算方法。 -

At the crossing of the 21th century, the three famous authors in the contemporary literature field all selected the un - normal perspective narrate, the block - head young master in the a - lai ' s novel of " the dust falling to the ground ", the madman in jia - pingwa ' s novel of " shanxi opera ", the moving soul in the shi - tiesheng ' s novel of " the journey of my dingyi ", selecting the perspective inherited luxun ' s tradition in " the diary of the madman ", it is a reference from the west and latin america ' s modern expression skill, it is making great efforts when they face the dilemma under the new situation
摘要世紀之交，當代文壇頗具影響力的三位作家不謀而合地選擇了非常態視角敘事，阿來《塵埃落定》中的傻子少爺，賈平凹《秦腔》中的瘋子引生，史鐵生《我的丁一之旅》中的行魂，這一敘事視角的選取既是對源自魯迅《狂人日記》中「狂人」傳統的承續，也是對西方、拉美等文學現代表現技巧的借鑒，更是新的歷史條件下敘述面臨困境時的創新努力。 -
