Abstract : in the research of internal combustion engine, recordingin - cylinder pressure and temperature is an essential technique to study the thermal cycle of internal combustion engine. the combustion analyzer developed in this study will give both the measurements at sampling points per crank angle or sampling cycle, calculate and show the real time parameters which decide the working process of internal combustion engine, such as pressure accelerating rate, indicateed mean effective pressure, cycle - to - cycle variation, heat release rate, etc. compared with the imported congeneric products, the analyzer has many advantages such as chinese interface, low price, easy operateing, convenience in maintainance and easy upgrading
文摘:為了測錄內燃機缸內的壓力及溫度，開發了一種內燃機燃燒分析儀.該分析儀由國產高速數據採集卡及自行開發的控制軟體組成.它不僅能精確設置每度曲軸轉角內采樣點的個數和採集循環數，而且在採集過程中能實時計算和表徵內燃機工作過程的壓力升高率、平均指示壓力、循環變動率、放熱率等參數.經實際使用以及與國外產品相比表明，此分析儀具有全中文界面、價格低、操作簡單、使用維護方便、功能便於擴充等優點I fancy d i could make all but the wheel, but that i had no notion of, neither did i know how to go about it ; besides i had no possible way to make the iron gudgeons for the spindle or axis of the wheel to run in, so i gave it over, and so for carrying away the earth which i dug out of the cave, i made me a thing like a hodd, which the labourers carry morter in, when they serve the bricklayers
可做輪子卻不那麼容易，我簡直不知從何處著手。此外，我也無法做一個鐵的輪子軸心，使輪子能轉動。因此，我決定放棄做輪子的念頭，而做一個灰斗似的東西-就是小工替泥水匠運泥灰用的灰斗，這樣就可把石洞里挖出來的泥土運出來。The interpolate technology just like a " ruler ", the resolving power of the " ruler " affect that the sampling points are arrayed correctly on time axis, and is determined by the multiple of the double slope integral amplifier. so it is core in the whole project. the project apply the complicated program logical device ( cpld )
內插技術的應用使得隨機采樣理論能夠得以實現，內插技術相當于測量用的「尺子」 ， 「尺子」最小分辨能力決定了最後采樣點重新在時間軸上位置排列的真實可靠程度，這里尺子的最小分辨能力是由雙斜率積分時間擴展器放大倍數決定的，所以說該模擬充放電放大電路在整個方案中是個很關鍵的部分。The main achievements are as follows : the theory models of defect mfl field are set up ; based on the magnetic dipole model and finite element model, the distribution of defect mfl field is simulated in the dissertation ; the component of flux density ( magnetic filed ) parallel to the surface of pipe is detected by a circumferential array of hall probes ; the factors including defect geometry parameters, defect surface angle and shape, pipe material, field intensity, vehicle velocity, background magnetization, operating pressure and remanent magnetization and so on influence the mfl signal characteristics
採用霍爾元件作為缺陷漏磁檢測傳感器，獲得管道軸截面漏磁場切向分量的漏磁信號；研究了缺陷外形尺寸、缺陷傾角和形狀、管道材質和磁化強度、檢測儀移動速度、管道背底磁場、管內壓力和剩磁對漏磁信號的影響。提出了各通道增益放大、各路漏磁信號偏離調整、波形微分、數字濾波和平滑等漏磁信號預處理方法；分析了等空間采樣的漏磁信號轉換為等時間采樣信號的必要性，研究了漏磁信號的小波去噪方法。The assisting mechanism of hammer in dredge haul is to accumulate energy with wire pull, draw inner pole firstly, release by pin framework, acceleratc core piece, strike hammer shell, produce great instantaneous wallop, drag dredge to break op stone immediately, restore with reposition spring, and work again finally
該機構在拖網取樣時利用鋼纜拉力蓄積能量拉動內部拉桿，並通過銷軸機構釋放能量加速沖擊芯塊，撞擊殼體產生巨大的瞬時沖擊力，拽動拖網破碎巖石，然後使用復位彈簧使機構復位，重新工作。Simulation comparisons verify the superior performance of the tri - state pwm technology. experimental results indicate that the current - controlled tri - state pwm switching power amplifier based on sample - hold strategy has high frequency bandwidth and fast dynamic response in a wide load range, which can well meet the demands of high - speed magnetic bearing
模擬結果驗證了電流三態調制技術的優越性能；實驗表明本文研製的基於采樣-保持策略電流三態調制開關功放具有結構簡單、效率高、紋波小、電流動態響應快、頻帶寬、受負載影響小等優點，能很好地滿足高速磁軸承的要求。However, we should not neglect a detail that the images have been placed along the timeline in a disorderly and unsystematic way : from the egyptian pyramid to the head of george washington, various images of people and events of all ages are put together in pell - mell ( at least seemingly so )
但同樣不應當忽視的一個細節是，時間軸中的影像是零散無規律的，古埃及的金字塔、華盛頓的頭像、古往今來各種各樣的人和事被混亂（至少貌似混亂）地擺放在一起。分享友人
