The dark - gray traction current deposits belong to internal - tide deposits, it develops sandstones and siltsands, and charactered with lenticular, wave, flaser bedding, bimodal cross - bedding and ripple mark
深水牽引流沉積為內潮汐沉積類型，巖性為細砂巖、粉砂巖，以發育透鏡狀、波狀、脈狀層理、雙向交錯層理、波痕等沉積構造為特徵。By the phenomenon came from critical sand - gravel granular mixtures slope experiment, the falling causation, form, scale, and preventing principal in sliding - sand slope were discussed. the causation can be drawn : the slope received sands from the slope top continuously ; non - uniform degree and granular size in strong weathering environment may be changing ; and the restrain in slope foot was weakened. these factors, cause the fal
結合乾燥沙石臨界單面坡實驗現象觀察，對溜砂坡災害的產生原因、崩塌特性及防治原則進行了討論，提出溜砂坡崩塌的三個主要成因：寒凍風化引起上部沙粒來源的持續不斷；坡面的風化作用使顆粒進一步均勻、細化，造成原來處于亞臨界而穩定的坡面達到臨界而容易失穩；坡腳對牽引式崩塌的制衡作用削弱，易受坡腳干擾而誘發。The testing result in sandy soil shows that the law that the principal parameters of the knives exert influence on the draft approximately approaches to the result theoretically driven out, and a pair of knives has been chosen to be a favourable one with satisfactory performance and smaller draft for the plastic film mulched corn field through the contrast tests to number of pairs of knives
砂質壤土中的試驗表明，鏟刀主要參數對牽引阻力的影響規律與理論推導結果相近。通過多副鏟刀的對比試驗，選取出對玉米茬地進行起膜、起茬作業時，性能良好，牽引阻力較小的鏟刀。Besides, the result of experimental study also indicates that the relationship between the forward speed of operation on the field of sandy soil and the draft appears exponential relation
試驗研究表明在砂質壤土中鏟刀作業速度與牽引阻力成指數關系。The acceleration time process of road surface plainness is got by using two integral calculus of the acceleration time process which is measured by five - wheel equipments. this data is worked as the input of the road surface for theoretical calculation. the result of experiments mostly fits that of calculation, and then the multiple - acceleration power spectrum distribution of the artillery and tractor are acquired
在瀝青路面、破損鋪磚路和砂石路面上以不同速度進行了平穩隨機激勵牽引試驗，用五輪儀測量得到的加速度時間歷程進行兩次積分的方法得到路面不平度的時間歷程做為路面輸入進行對應的理論計算，試驗結果和計算結果基本相符，得到了火炮和牽引車多個加速度功率譜分佈。Finally, your personal pets should be current on vaccines, including bordetella for dogs. what do we provide ? we provides the basics - food and litter, training crates, collars and leashes
