With the experiment part, the errors of sk - 21 nc machine tool have been measured, and a serial of data is gotten which lead to the error discrimination. ( 3 ) based on the kinematical theory of mbs, the calculation methods for the ideal center envelop curve of grinding wheel on cam grinding, the practical cutter track, inverse contour of cam, ideal nc instructions, precision nc instructions, the inner / outer normal and the fitting criterion of curve have been all discussed in detail in this paper
（ 3 ）通過精密加工的約束條件方程，探討理想刀具路線、逆變數控指令與實際刀具軌跡之間的映射關系，解決誤差補償技術提高加工精度的核心問題? ?當要求數控磨床的砂輪中心準確到達給定的理想點時，精密數控指令值究竟該是多少，如何能夠通過計算，獲得這樣的數控指令值，給出經修正的數控指令計算方法。 -
3, logging curve comparison results show that in the west part of south region there is a grade 4 normal fault, and the separation is 4 - 6 meters. five microstructure types and 8 top and bottom composition patterns have been proposed. the relationship between microstructure and deposition facies was studied and the genesis relationship was confirmed, that is, top microstructure is mainly corresponding to nature levee, contrasting to that of the bottom microstructure
提出了五種微構造類型及八種頂底微構造組合模式；並研究了微構造與沉積相的關系，發現它們之間存在一定的成因聯系，即頂面微構造中高點、鼻狀和斷鼻構造主要對應于邊灘微相，低點與溝槽微構造則主要對應于天然堤微相，而底面微構造正好與之相反。 -
In this paper, an approach of the systematic artificial neutral net was introduced into the analysis on the ship - against - bridges probability with a computer programs. based on the basic data of the present 12 typical bridges as the sample, 4 chief influential factors as the input coefficient, such as the bridge span, the water flow rate, the incline angle between water flow direction and the direction normal to bridge axis, and the curve in the course near the bridge area, with the ship - against - bridge probability as the output coefficient, the intelligent judging system of the ship - against - bridges probability reflecting the influence of the above input parameters is obtained after training
本文首次將人工神經網路系統方法引入了船撞橋概率的研究當中，編制了計算程序，成功地以現有12座典型橋梁的基礎數據為樣本，以橋梁跨徑、水流流速、水流方向與橋軸法線的夾角以及橋區航道彎曲度等4個船撞橋主要影響因素為輸入參數，以船撞橋概率為輸出參數，經訓練得到了能較好地反映上述輸入參數影響的船撞橋概率判斷系統。 -
The gradient falls off to the starting color based on a bell curve shape normal distribution to either side
漸變過程基於一個鐘形曲線（正態分佈）向兩端的起始色過渡。 -
The micro boundary layer experiment is carried out from 8mm to 14mm of a 15mm - long micro plane. re numbers vary from 35, 000 to 150, 000 and 4 different mach numbers are selected. some new characters are discovered, such as velocity curve factor is smaller than that of well developed normal scale turbulence boundary layer
微尺度平板邊界層實驗選取從總長度為15mm的微平板前緣8mm到14mm之間的7個站位， 4種馬赫數， 13個不同雷諾數（從35000到150000 ）的實驗狀態，發現了該尺度下邊界層流動的一些新的特點，如形狀因子比常規大尺寸下充分發展湍流狀態的形狀因子更小等。 -
In contrast to phase separation ( curve - fitting ) approaches which are largely mathematical, phase resonance testing is a physical technique. when a structure is vibrating in a normal mode, the undamped natural frequency and normal - mode shap of the structure are directly measured. in the classic phase resonance testing, the test data processing is simpler and the results are more accuracy
相對于相位分離法來說，相位共振法是一種比較直觀的物理識別方法，在結構做「純模態」振動時，通過物理測量直接獲得模態參數;試驗數據處理工作量小，且精度一般比單輸入系統高。 -
Research indicates that this idea is also applicable for the carbonate. to set up a suit of idea of travel time reading of carbonate interval and use real pressure data to correct it during plotting the normal compaction trend curve are rather important. the method is applied to the prediction of formation pressure in luojiazhai and dukouhe oilfield successfully
研究認為，此種方法在碳酸鹽巖剖面同樣適用，關鍵是建立一套適合於碳酸鹽巖剖面選取視泥巖層段的聲波時差讀值方法和在構建正常壓實趨勢線時，根據趨勢線所計算的泥巖段聲波時差值和實測正常壓力資料修正該趨勢線。
