通過調節可調式拉法管的喉徑以及各壓力參數實現了輸送參數的相對最優，在一定程度上減輕了糧食顆粒在輸送過程中的破碎率。As this is a tight fitted pe which was temporarily reduced by 10 % of its original od through a special die before lined into the old system, which the pe pipes resumed the original od after release of tensile force
由於這是緊配合的聚乙烯襯管，在放入原來管道之前，原外徑暫時用專用模頭減少10 % ；當拉伸力釋放后，聚乙烯管道恢復原有的外徑尺寸。That is to say, the amount of the springback decreases with the increase of the pre - stretch force and lateral compression, and the decreasing trend is close to a linear relation, and when the lateral compression is large enough, the negative springback appears
理論分析和試驗均表明：回彈半徑隨著預拉力和側壓力的增大而減小，減小趨勢基本為線性關系，當側壓力足夠大時，出現負回彈。With the input of a vibration acceleration history of subway train, a full dynamic analysis of soil - pile - structure is carried out. the propagation of vibration wave on the ground and vibration responses of the huge platform and the storied buildings are analyzed. some conclusions are drawn as follows : ( 1 ) with the increase of the distance to the vibration source, vibration intensity of the ground decreases ; ( 2 ) the vibration intensity of the ground in vertical direction is slightly larger than that in horizontal direction ; ( 3 ) with the increase of the distance to the vibration source, the situation that the vibration intensity of each building in horizontal direction is maximum at highest and lowest story whereas minimum at the middle story changes gradually to that decreasing with the height of building ; ( 4 ) in vertical direction, the vibration velocities and accelerations at the end points of each story of a building are the nominal identical, which indicates that the vertical vibration of them is unanimous ; ( 5 ) the vibration intensity in vertical direction of a building is larger than that in horizontal direction ; ( 6 ) increasing of the elasticity of track is an effective way to abate vibration of ground and buildings
本文以北京地鐵八王墳車輛段地上超大結構（車輛段大平臺及其上的小區樓房）及其地基基礎為研究對象，在研究和分析有關資料的基礎上，用快速拉格朗日有限差分法軟體flac建立了二維數值分析模型，並以列車振動加速度時程作為模型輸入，進行了地基?樁基礎?地上結構的整體動力學分析，分析了地鐵列車運行產生的振動在地面的傳播規律及其對地上結構的影響，得到了如下結論： （ 1 ）隨著與地鐵線路距離的增大，地面的振動強度有減小的趨勢； （ 2 ）地面豎直方向的振動強度較之水平方向的略大； （ 3 ）隨著與振源距離的增大，在水平方向上，地上各幢樓房的振動強度由底層和頂層的最大、中間層的最小逐漸過渡到沿樓層增高而減小； （ 4 ）在豎直方向上，每幢樓各層端點的振動速度、加速度完全相同，表明樓房各層在豎直方向上的運動狀態一致； （ 5 ）各幢樓房豎直方向的振動強度比水平方向的大； （ 6 ）增加軌道彈性是減輕地面和地上建築振動的有效途徑。分享友人
