Experimental results indicate that for the polystyrene particle with a larger size, Umf changes with p-0.3, and for the sand particle with a smaller size, Umf changes with p-0.21. An empirical equation about Umf is proposed based on the experimental data: Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝ It is found that the bed expansion height increases with the increasing of gas velocity, and increases with pressure for fixed value of UUmf, when the pressure exceeds 0.7MPa, the influence of pressure on the bed expansion height is weakened.

研究结果表明，大粒径聚苯乙烯颗粒的Umf与p-0.3成比例，小粒径石英砂的Umf与p-0.21成比例，并根据实验值拟合出压力下最小流化速度公式为： Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝床层膨胀高度随气速的增大而不断增高，在相同UUmf下床层膨胀高度随压力的增大而增高，在大于0.7MPa时，压力对膨胀高度的影响减弱。

The MPR was used to measure the height and width of posterior arch in the point of vertebra artery overpass, the height of lateral mass benenththe posterior arch and the height and width ofC2 interarticular isthmus.

结果 寰椎椎动脉沟处后弓高度为4.54±1.17mm，椎动脉沟处后弓宽度为8.69±1.12mm，寰椎后弓下侧块高度为4.98±1.07mm，枢椎峡部高度6.95±2.24mm，枢椎峡部宽度6.75±1.39mm，男、女2组之间没有统计学差异。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

A new method and the principle is presented for plotting the critical metacentric height curve which meets IMOs intact stability criteria and weather criteria,and the critical metacentric height curve which meets 1976 SOLAS intact stability criteria. And the critical metacentric height curve is used in the Stability check of bulk grain carriers in accordance with the stability rules for bulk grain carriers.

本文还具体给出了满足IMO完整稳性和天气衡准的临界初稳性高度的求作方法，以及满足1976 SOLAS公约散装谷物船舶的稳性衡准要求的临界初稳性高度的原理和求作方法，并将由此得到的临界初稳性高度曲线综合运用到散装谷物船舶的稳性校核。

Height of Bitches --From28 inches upwards. There is no objection to a bitch being large, unlesstoo coarse, as even at her greatest height she does not approach thatof the dog, and therefore could not be too big for work as overbig dogsare.

雌性的高度：28英寸以上，只要不显得粗糙，不拒绝更大的雌性，她适合的最大高度不应该接近雄性的高度，就象不可能有太大的雄性一样。

A relationship between the frequency of occurrence and diversity of AM fungi and the elevation of the sampling sites for Swietenia macrophylla was observed. The elevation significantly affected the frequency of occurrence and diversity of Gigaspora and Scutellospora, but showed no significant influence to Glomus and Acaulospora.

通过对不同海拔高度Swietenia macrophylla根际AM真菌分布的分析表明，海拔高度显著影响着AM真菌的分布，Gigaspora属的真菌随海拔高度的增加显著升高，Scutellospora属的真菌则显著降低。

The results show that the reduction of free height of steel 44Si2CrV spring under compressive stress 900 MPa consists of two parts: plastic deformation of surface decarburized zone to hinder elastically deformed internal material recovering, making up 84% of total reduction of free height and creep of steel at ambient temperature makin...

结果表明，44Si2CrV钢弹簧在900 MPa的应力下压缩72 h，自由高度的缩短由两部分组成：表面脱碳层的塑性变形，造成对内部材料的牵制而使部分弹性变形不能恢复，由此所造成的弹簧自由高度缩短占总变形量的84％；钢的室温蠕变，占自由高度缩短的16％。

The diffracting optical element includes two layers equal in the height of the relief pattern and opposite to each other in the direction in which the height of the relief pattern varies in a period, and another layer differing in the height of the relief pattern from the two layers.

衍射光学元件包括在凹凸模式的高度上相等并在凹凸模式的高度在一个周期内变化的方向上彼此相反的两层，以及凹凸模式的高度不同于所述两层的另一层。

In the period of planned economy, China practiced a highly centralized planned management system, corresponding to which was a highly politicized administrative management system.

在中国的计划经济体制时期，实行的是高度集权的计划管理体制，与这种高度集权的计划管理体制相配套的，是一种高度政治化的行政管理体制。

Variance and correlation of the data was analyzed with SPSS software. It was found that height, width, and thickness are main factors influencing paper angle bead compressive strength; moreover there are linear relations between the height, the width, and the thickness of paper angle bead and the compressive strength, and the error of equation is ±3%.

通过SPSS软件对数据进行方差及相关性分析，确定了纸护角的高度、宽度、厚度是影响纸护角抗压性能的主要因素，并且高度、宽度、厚度值与纸护角抗压强度之间呈线性相关；最后利用SPSS的线性回归分析，得到纸护角的抗压性能与高度、宽度、厚度之间的线性回归方程，对方程进行验证，其误差为±3%。
