他在草地上來回走動，慢慢地拖著兩只腳，蹭得地上的草沙沙作響，眼睛盯著靴子上的塵土他有時邁著大步，盡可能踩上割草人留下的腳印，有時數自己的腳步，計算走一俄里要經過多少兩條田壟之間的距離有時采幾朵長在田壟上的苦艾花，放在手掌上揉碎，然後聞那股強烈的甘苦香味。Abstract : aimed at the circumstances including deeper formation, wider wells " distance, few data in new exploratory zone and lower drilling success rate, etc., the paper discussed the drilling geological environmental factors such as seismic velocity and acoustic wave logging velocity, and put forward a set of technical methods including basical data treatment in deep exploratory wells, drilling optimal design and operations
文摘:針對塔里木盆地沙雅隆起井眼深、井距大的難點和新靶區探井參考資料少、鉆井設計盲目性大、鉆井成井率低等問題，分析探討了地震層速度和聲波測井速度等鉆井地質環境因素變化規律，提出了一套深探井鉆井基礎數據處理、鉆井優化設計和優化施工的技術方法。The main factors have been determined to be the depth and width of hole, the strength of surrounding rock, the types of detonator, the decoupling coefficient, burden and unit consumption form what has been discussed, the author make use of those major factors as standard of affection and studied bp neural networks " work principle, structure and defectiveness. a model of modified bp neural networks has been used to built model in order to identify selection and optimize of blasting in rock anchor beam. triumphant parameter design of blasting were selected as a example, in order to perform network of parameter design
確定以炸藥類型、最小抵抗線、孔深、炮眼間距、不耦合系數、線裝藥量、巖石強度和巖體完整度為主要影響因素；把改進的bp演算法應用在爆破參數優化設計中，建立以炸藥類型、最小抵抗線、炮孔深度、炮眼間距、線裝藥量、不耦合系數、巖石強度和巖體完整度為主要影響指標，選擇45例國內外成功的爆破參數設計實例為樣本，利用bp神經網路進行爆破參數優化設計，並通過現場保護層和巖臺修面爆破試驗以及對其松動圈范圍進行聲波測試，其測試結果最優的爆破方案其松動圈最小，這與神經網路進行參數優化設計的爆破方案相吻合。Because the rangefinders you will use this on have viewfinders that are designed for the angle of view of 50mm lenses, you will need a special viewfinder to put in the accessory shoe in order to properly frame your subject
