Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。

5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

From the point of view of structure,bamboo cell wall ratio,amount of bundle per unit area,fraction of bundle sheath,fraction of vessel increase from the root to the top of the bamboo,while fractionof parenchyma.Single bundle sheath area decreases with the increase of height.Fiber length,fiber width and vessel length increase from the root to the top andget theirs maximum value at the length of 17th node to 23rd node and thendecrease.Fiber length and width ratio slightly decreases while vessel widthincreases with the increase of height.

从构造角度来说，竹材胞壁率、单位面积维管束个数、纤维束比量、输导组织比量从基部到到梢部随着高度增加而增加，而薄壁组织比量、单个维管束纤维束面积随着高度增加而减小；纤维长度、纤维宽度、导管长度从基部到梢部随着高度的增加而增加，在第17竹节到第23竹节达到最大值，而后下降，纤维长宽比随着高度的增加而缓慢下降，导管宽度随着高度增加而一直增加。

The results showed that soil wind erosion was the near-surface wind-sand activity. The sediment particle saltates mainly in 7.5-43.5 cm. Wind sediment amount decreased along height, which correlate well with power function, exponent function and logarithm function. The sediment particle composition was influenced strongly by wind erosion intensity and topsoil characteristics. However, the regularity of sediment composition was distinct in a definite paticle size in different heights. Wind erosion amount increases with wind speed exponentially, which was influenced by times that the wind does.
