  1. 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。
  2. This paper stuffed with twelve important grain and vegetable crops, studied the injury symptom, dose reaction, injury threshold value and influential factor of main pollutant so2 on various plants, tested the dynamic transformation of pod, cat, mda, soluble protein, free pro and chlorophyll of resistant plant and sensitive of these physiological biochemical transformation with plant resistant ability. meanwhile, simply studied the protective role of the five compounds on plant. the result indicated the followings

    本實驗以12種重要的糧食和蔬菜作物為研究對象，研究了主要大氣污染物二氧化硫（ so _ 2 ）對不同植物的傷害癥狀、劑量反應、傷害閾值以及影響因素，測定了抗性和敏感植物在受到so _ 2污染后植物體內過氧化物酶（ pod ） 、過氧化氫酶（ cat ） 、丙二醛（ mda ） 、可溶性蛋白質、游離脯氨酸和葉綠素的動態變化，並分析了這些生理生化變化和植物抗性的相互關系，同時還對5種化合物溶液對植物的保護作用進行了初步研究，結果表明： 1
  3. Resistance ability from endogenous protective enzyme systems in the plants was enhanced by heavy metal stress inducement in restricted range, while defence reaction crippled as the aggravation of the damage

    植物內源保護系統的保護作用受到脅迫后在一定限度內能被誘導加強，防禦反應隨著重金屬離子毒害程度的加重而減弱。
  4. With the accomplishment of this system, the level of airspace management and evaluation is improved, and the means of airspace management and evaluation is enhanced. at the same time, the general protective ability of airspace management system can be improved
