In this paper, it also analyses the disadvantages of methods in present pavement specification. by means of parallel field test experimentation, and gives the correlativities between test methods of specification and new pattern test methods, such as road surface profiler, ground penetrate rada test system, friction test vehicle, falling weight deflectometer. based on these correlativities, their test and quality control standards are formed
本文還分析了路面現行檢測方法存在的問題，通過現場不同方法的對比檢測，建立了激光平整度測試車、探地雷達測試系統、摩擦系數測試車和落錘式彎沉儀（ fwd ）等新型檢測方法和規范測試方法間的相關關系，從而提出新型檢測的質量控制標準。5. the methods of temperature - correcting on copper cylinders and copper spheres are discussed. the method of unitive temperature - correcting on plastic pressue - measuring elements is put forward for the first time. large quantities of quasi - dynamic calibration tests in different temperatures are carried out on the dropper - hammer hydraulic dynamic pressure calibration device and the unitive temperature - correcting formula which accords with the traditional correcting method is got
在落錘液壓動標裝置上組織了多批次的銅柱、銅球高低溫準動態校準試驗，探討了建立溫度誤差統一修正公式的可行性，建立了測壓銅球，測壓銅柱符合我國傳統修正方法的溫度統一誤差修正公式。Power bond graph is used to established the bond graph model of the lifting and dropping of hydraulic pile hammer and state space equation in the paper for hydraulic pile hammer is perplexing nonlinear system. in order to attain the graph that pressure, position, velocity, acceleration vary with time in the course of driving pile simulation procedure solving state space equation is designed on the basis of combining four - order runge - kutta method with predicator - corrector method, dynamic simulation of the hydraulic system is studied in matlab 6. 5. it is convenient to analyse dynamic characteristics of the hydraulic syste m, beneficial to the design and parameter optimization of the hydraulic system. in the final part of the paper, under detailed analysis of the control characteristics for double - acting hydraulic pile hammer with double cylinders, control system based on the programmable logic controllers founded on technology of modern compute is designed
由於液壓打樁錘液壓系統是一個復雜的非線性系統，本文採用功率鍵合圖法建立液壓打樁錘上行、下降的鍵合圖模型和狀態空間方程，通過四階龍格?庫塔法和預估?校正法相結合編制了模擬程序對狀態空間方程求解，在matlab6 . 5中進行液壓系統的動態模擬，獲得液壓打樁錘運動過程中壓力、位移、速度、加速度等隨時間變化的曲線圖。此曲線圖方便了對液壓系統動態特性分析，為液壓系統的設計和參數優化提供了有益的借鑒。最後，在深入分析雙缸雙作用液壓打樁錘控制系統的功能要求后，採用了以現代計算機技術為基礎的新型工業控制裝置? plc可編程式控制制器，設計出了雙缸雙作用液壓打樁錘的電器控制系統。Sun learned wu hao style t ai chi chuan from hao wei - chen, who was li i - yu s chief disciple. sun started studying with hao relatively late in his life, but his accomplishments in the other two internal arts led him to develop his t ai chi abilities to a high standard more quickly than is usual. he subsequently was invited by yang shao - hou, yang cheng - fu and wu chien - chuan to join them on the faculty of the beijing physical education research institute where they taught tai chi to the public after 1914
二十世紀五十年代初期，北京武術界成立過聯誼會，會址設在德勝門內北京匯通武術研究社，每逢北京武術界舉行聯誼大會演時，李瑞東先師的入室弟子、匯通武術研究社社長、著名武術家高瑞周老師出場表演他拿手的低架慢拳，就是李式太極拳（太極五星錘） ，獲得了武術界的好評。Steel die forgings - tolerances on dimensions - part 1 : drop and vertical press forgings ; german version en 10243 - 1 : 1999
