Considering the influence of material original flaw , the thesis gave the 4 # 125t crane of no . 3 steel - making plant of maansan steel co . for example to analyze the designing and remaining life of the crane ' s girder by using damnification limits design method . the method was based on the theory of rupture dynamics and the principle of disrepair - security 本文以马钢第三炼钢厂4 # 125t铸造起重机主梁下盖板大面积可见裂纹情况为例，考虑材料初始裂纹的影响，在断裂力学理论和破损?安全设计原则的基础上，采用损伤容限设计法来重新计算铸造起重机的设计寿命；并对正在服役的铸造起重机计算其剩余寿命，为铸造起重机的安全运行提供了较可靠的理论依据。
Again , because the ion influx technique have a little damnification on the skin - deep structure for the cdte thin films , among the experiment , we have let the doped cdte thin films be annealed a hour with n2 atmosphere at 500 , and then slowly cooled until the room temperature . via the test and analyse , heat treatment has very important effect on the comeback of crystallattice surface disfigurements . finally , the films were characterized by x - ray diffraction ( xrd ) , scanning electron microscopy ( sem ) , ultraviolet visible ( uv ) and the hall effect measurement 再次,由于离子注入会对薄膜表面的结构造成损伤,本实验把被注入离子的cdte薄膜在n2气氛中500下退火1个小时,然后缓慢冷却至室温。经测试分析,热处理对晶格表面缺陷的恢复有很重要的作用。最后,利用xrd 、 sem 、紫外可见分光光度计及hall测试系统研究其结构,表面形貌和光电性能。
This paper deploys research about the damnification identify , employ capacity and reinforce technology with reason of double bend arch bridge through finding out disease position of construct and cause , colligating these result of the actual bridge detection and load test and analysis and research on the theoretics of damnification , and so on , despending on a lots of measure and means , finding out its present condition and checking structure internal force through choosing the proper mechanics model according as a lots of prototype information 本题以安徽省省道s310上k139 + 000处的大店岗桥为实例，从检测入手，利用各种检测方法和手段，了解双曲拱桥的现行工况，并依据各类原型资料选择合适的力学模型进行结构内力验算，通过荷载试验、理论分析等方法，查明结构的病害部位和形成原因，综合实桥检测结果和荷载试验结果以及损伤理论的分析研究等等，展开对双曲拱类桥型的损伤鉴定、使用能力和合理加固技术方法的研究。
The main contents of this paper is according to the structural characteristic of forced vibration , making use of the varying quantity data of free frequency of two different physical cantilever beam on the structural damage experiment basis , then using the bp network , genetic algorithm and the genetic bp algorithm to build up relation model between position , extent of structural damnification , and the varying quantity of free frequency 其主要内容就是根据结构受迫振动特性,利用试验测得两根不同物理性质悬臂梁在受损伤产生裂纹前后的固有频率改变量,使用bp网络、遗传算法、遗传bp算法,建立了结构损伤的位置、程度与结构固有频率损伤前后改变量之间的关系模型。
In conclusion , the method of enzymolysis combined with hplc to extract cp i from pigskin was proposed . this method showed the adventages of high performance , high selectivity and easily amplification . acoording to the experiments of identifying the physico - chemical property and the biosafety of cp i , it was concluded that cp i had high bioactivity and no toxicity effect , and that cp i had the ability to protect cells from oxidative damnification 综上所述，利用酶解和高效液相色谱制备相结合的方法可以从猪皮中分离纯理学硕士学位论文: i型胶原蛋白的制备、鉴定及其抗uva氧化损伤作用的初步研究化cpi ，该方法具有高效性，高选择性和易放大性;理化性质鉴定及生物安全性试验表明，该物质为纯活性胶原蛋白，无毒副作用;同时对体外细胞的uva氧化损伤具有较好的保护作用。
The detecting and measuring instrument used for detecting and measuring surface tension by means of bio - solution and sense finding methods at moving conditions is developed in order to detect and measure surface tension adsorptive ratio and diffusivity of the active substance of the alveolus surface and other life - forms . the alveolus burned by breath in the high temperature condition or damnified with serious sickness will destroy the active substance of the alveolus surface . detecting and measuring surface tension of the active substance of the alveolus surface and other life - forms can help us determine the extent of pathological changes or damnification of the alveolus or other apparatus which can produce the active substance . lt is the research problem of the modern times medicine 生物液智能表面张力动态测试仪是为测试肺泡肺液表面活性物质的表面张力、吸附率和扩散率以及其它生物液的表面张力而研制的。高温条件下通过呼吸而烧伤肺部，或者因某些严重的疾病而损伤肺部都将会破坏肺部表面活性物质。通过测试肺泡或其它生物液表面活性物的表面张力，可以帮助我们测定肺泡或其它产生活性物质的器官病变损伤的程度。
