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。Based on the principles of restoration ecology and main aim of karst vegetation restoration at present, take huajiang canyon with a typical degraded vegetation area located in southwest guizhou as an example, we study bio - ecological features of the volunteer plants with some economic values and the soil environment, for the purpose of making some models of the pioneer plants to popularize

文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映Based on the study of strength degradation of material in the fatigue process, a strength degradation model is proposed. a stochastic differential equation, which controls strength degradation, is obtained from the model randomized by markov process. by using the theory of stochastic, the distributions of residual strength at any given lifetime and lifetime of any given residual strength are attained. under a few suitable hypotheses, inverse gaussian distribution of fatigue life is derived, and verified by means of experimental data. the result shows that the model and the method are reasonable
