With PA1010 as matrix material,maleic anhydride grafted ethylene-propylene rubber as toughener,PA1010／MGEPR blend was prepared by means of Brabender PLE331 Rheometer.The apparent viscosity,non-Newtonian indx and melt activation energy of the blend were determined,and the rheological properties of the blend were centered on in our study.

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.

研究表明：桉树不同家系间木材物理力学性质和化学组成存在差异；粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异，株间、株内木材材色存在变异；桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异，在同一家系或同一无性系中，株间和株内也存在着相同的变化规律；桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关，侵填体含物越丰富，纹孔附物越多，桉材越容易皱缩；最大瞬间皱缩是能产生更大干燥降等的临界点，在制定干燥工艺时，必须在最大瞬间皱缩发生时，采用温和条件，使已产生最大瞬间皱缩的细胞尽可能多的恢复，尤其不能使其产生永久变定；在常温条件下，影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量；而对于瞬间皱缩和最大瞬间皱缩，几乎所有细胞都参与它们的形成过程；对于易皱缩的桉树木材，间歇干燥是最有前途的干燥方法。

The CCT curve s under deformed and undeformed conditions were obtained by way of thermal dilation and metallography.

用 Gleeble-1500型热力模拟试验机研究了含钛高强度钢变形奥氏体在连续冷却过程中的相变规律，用膨胀法结合金相法建立了该钢变形和未变形奥氏体的连续冷却转变曲线，并探讨了该钢的热轧可行性。

The effect of undissolved ferrite amount on contact, impact and bending fatigue properties were studied. The stress relaxation and grain refinement due to occurring of plastic deformation are main reasons of improving the fatigue life.

就未溶铁素体含量对接触疲劳、多冲疲劳及弯曲疲劳性能的影响机理进行研究，局部的应力集中因铁素体发生塑变而得到松弛和细化晶粒是提高疲劳寿命的主要原因。

According to range of the focal distance, dropping UV glue which is crystalline and unexpensive into lens cavity with UV rays, and then forms as soon as solidifies the convex lens. Combining UV curing glue convex lens and variable focus lens, the focal distance range achieves the 8.3~24.5 mm low focal distance effect.

於此之后根据变焦效果的需要，利用UV胶透光性佳、成本低，将UV胶滴定於透镜腔体中，形成一凸透镜，藉由变焦透镜与UV胶透镜结合，焦距变化达到8.3~24.5mm范围的低焦距效果。

First, each morphometric character is related to fork length by linear regression analysis and each relationship is considered as a unit character.

首先，以每一非体节形质对尾叉长做廻归判定，其次，以变积分析法比较各个非体节形质，在雄雌间及各海域标本间之异同。

The equations of the towed cable motion are based on Ablow and Schechter model and six degree-freedom ordinary differential equations are used in the analysis of the motion of a towed body. The partial differential equations are discretized by finite difference method and the transient values of towed body depth and cable tension are computed by Newton Iteration when the heave compensation system performs and the length of the cable varies.

拖缆动力学模型基于Ablow and Schechter模型，拖体采用水下运载体六自由度方程模拟，运用有限差分法离散偏微分方程组和牛顿迭代法计算变缆长情况下拖体深度与拖缆各点张力的动态取值。

Creep cracks seem always to initiate at inherent casting pores and slowly propa-gate anisotropically along the (001) planes, perpendecular to axis of stress applied, upto the final fast fracture. Creep cracks can also nucleate at fractured carbides or at in-terfaces between carbides and matrix in the alloys containing more carbon.

结果表明：单晶的蠕变断裂具有明显的晶体学特征，蠕变裂纹总是从已有的铸造的显微疏松处萌生；对于含碳量较高的材料，碳化物及其与基体的界面也是裂纹萌生的有利位置；这些已萌生的裂纹在外加应力轴垂直的(001)面上各向异性地扩展，直到由于承载截面的逐渐减小而导致最终破坏。
