降低速度

To avoid the rebar cage uplifts, the speed of concrete casting should be lowered down when the concrete is cast to about 1m under the rebar cage's bottom; when the casting progresses to 4m above the bottom of the rebar cage the tremie should be lifted up to ensure it's bottom is 2m above the rebar cage's one, and then the normal casting speed can be resumed.

为防止钢筋骨架上浮，当灌注砼顶面距钢筋骨架底面1m左右时，应降低砼灌注速度，当砼上升至钢筋骨架底面4m以上时，提升导管，使其底口高于骨架底部2m以上，即可恢复正常砼灌注速度。

A continuous increase in FS increased L value, A-lys, SF, pressure and torque; but decreased TI, NSI, WHC and OAC; chewness increased from 4r/min to 8r/min, but decreased rapidly when FS raised from 12r/min to 16r/min, there was a little change between 8r/min and 12r/min, there was also changed unsignificantly between 16r/min and 20r/min.

随着喂料速度的升高，产品的亮度指数、有效赖氨酸含量、剪切力、压力和扭矩逐渐升高；组织化度、氮溶解指数、水分保持能力和吸油性逐渐下降；当喂料速度由4r/min升高至8r/min时，咀嚼性逐渐升高，由12r/min升高至16r/min时，咀嚼性迅速降低，8r/min与12r/min之间变化很小，16r/min与20r/min之间变化很小。

It could be seen that, reduce the crystalize temperature could raise the crystallizing rate, but the completness of the crystal reduce.

由此可以看出，降低结晶温度提高结晶速度，但晶体的完整性降低。

In order to illustrate the phenomena occurred in the technological experiments, the infiltration dynamics of liquid aluminum into porous media was simulated in accordance with the laws of similitude. The results show that (1) the relation between the displacement of infiltration front and the advancing time is 〓;(2) the pressure of infiltration changes with time according to 〓;(3) the distribution of pressure in the direction of infiltration length is P=a〓+b〓L.(4) the change of temperature or viscosity of molten aluminum affects infiltration velocity in fillers of diameter in the range of 1. 5～5. 5mm very little, but this velocity in fillers of diameter 0.5mm is reduced with the decrease of AL temperature.

为了说明工艺试验中显示的各种现象，作者根据相似原理，采用模拟试验研究了铝液在多孔介质中的渗流过程，得到铝液渗流动力学规律如下：（1）渗流前沿位移—渗流进行时间关系为〓；（2）渗流压强随渗流时间的变化规律为〓；（3）渗流压强沿渗流长度分布为P=a〓+b〓L；（4）铝液温度降低或粘度加大时，对大于1.5mm的颗粒之间的渗流速度影响不大，但使0.5mm颗粒之间渗流速度减小。

In our study after adding the helpsoak reagent into the gold ore,some minerals have the chemical reaction with it,increasing the gold cyaniding speed,the leaching rate has achieved 90%~92%.

在氰化过程中，Cu容易形成Cu2沉淀覆盖在矿物表面上，阻碍金的继续浸出。氰化刚开始，金的浸出速度快，18h后氰化浸出速度降低，26h后金的氰化浸出停止。

A vocal speed increases since some pitch periods is deleted from a vocal signal sequence. However, if pitch periods is inserted or deleted, it causes the phases uncontinuous and the sound pulsated.

插入部分基音周期使语音速度降低，删除部分基音周期能使语音速度提高。

Experimental results show that the reaction between hydrochloric acid and sludge under airtight condition is an equilibrium reaction, the reaction rate decreases exponentially with the increase of the initial pressure, the system gelling time increases with the decrease of the pH value, and the plugging performance of the waterglassgel enhanced foam system is superior to that of ordinary foam system due to the small foam diameter and high interfacial film strength.

实验结果表明：盐酸与污泥的反应在密闭条件下是一个平衡反应，且其反应速度随初始压力的增加呈指数降低；体系的胶凝时间随着pH值的降低而增加。由于体系的泡径小，界面膜的强度高，因而水玻璃凝胶增强泡沫体系的封堵效果明显优于普通泡沫体系。

According to the velocity filed mentioned above, the contour of the drawing die was rationally designed. To prove its applicability and superiority, FEM software, MARC and SUPERFORM, were used to simulate the drawing process of cross tube in "conical die" and "streamlined die".

本文以十字形钢管为研究对象，开展对异型钢管拉拔成形过程研究，首先结合挤压流线理论，设计了&流线型&拉拔速度场模型，这为改善金属流动状态、降低能耗创造了良好条件；紧接着以&流线型&速度场为理论依据，对十字形管拉拔模具的凹模轮廓进行了合理设计。

In the process of wood drying, because that the dry rate on the surface of wood is ten times than which inside, the moisture content of wood on the surface reduce to the fiber saturation point first, and begin to shrinkage, but the moisture inside content of wood is far higher than the fiber saturation point, the higher the standard criterion in wood drying, the more obvious of shrinkage.

摘 要：在木材干燥过程中，由于木材表面水分的蒸发速度比木材内部水分移动的速度大10倍左右，因此木材表面的含水率首先降低到纤维饱和点，并开始发生干缩，而此时木材内部的含水率还远远高于纤维饱和点，干燥基准越硬，这种现象越突出，木材发生开裂的可能性就越大。

In addition, the leakage coefficient decreases with the decrease of gap width at the same rotational speed.

研究结果表明：用相对流量系数（转动时的流量系数与静止时的流量系数的比值）与速比（周向速度与轴向通流速度的比值）的函数关系表征泄漏量随转速变化的规律时，存在一个临界速比约等于1.0；低于这个临界速比时，转速对泄漏量的影响不明显；高于这个临界速比时，泄漏量随转速的增大而减小，在很高的转速下（6000r/min以上），泄漏量至少减小了5.1%；相同间隙下，泄漏系数随着压比的提高而近似线性增加；相同转速下，随着密封间隙的减小，相对泄漏量逐渐降低。
