Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。

It was also found that the chromosomes paired well and formed a rod heteromorphic bivalent in the hybrid F1[73(36)9-1×CSDT 1BL]. Whereas 73(36)9-1 produced mainly configuration of 20''+1'+t' when test-crossed with CSDT 1BS. It showed that the translocation occurred on chromosome 1B short arm, and this segment came from rye chromosome 1RL. In the present paper we discussed also the way in which the translocation might be caused, and concluded that it was formed through reunion of two kind telocentrica (1BL and 1RL) after simultaneous misdivision of two univalent chromosomes (a wheat chromosome 1B, and a rye 1R).

同时还发现，73（36）9-1和"中国春"双端体的1BL能很好地配对并形成一个棒状的异形二价体，而它和CSDT 1BS的染色体则主要产生20+1′+t′的构型，从而证明易位发生的可能途径，推断是由于在F1花粉母细胞中的两个单价体（一个是小麦染色体1B，一个是黑麦染色体1R）同时进行错分裂之后产生的两种端着丝点染色体（1BL和1RL）重新并合形成的，因而冬小麦73（36）9-1可能是一个自发产生的易位系。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

The results showed that at the anaerobic phase, the PHB concentration in the cell and orthophosphate concentration of the anaerobic effluent obviously increased, the poly-P concentration in the cell decreased, and the cucci and bacilli with a size of 1.0~1.5 μm were dominant and formed grapy cellular cluster. At the anoxic phase, the PHB concentration and orthophosphate concentration decreased significantly, the amount of poly-P increased, and the elliptical cucci of 0.5~1 μm and spheral bacilli of 1.0~1.5 μm were dominant. At the aerobic phase, the PHB and orthophosphate concentration almost reduced to zero, the poly-P increased significantly, cucci appeared single or in pair, and the contour of sphere was blur and almost disappeared.

And the strengthening mechanism can be described as follows: WC cemented carbides have interlaced short-clubbed grain, and in the bend strength test, the microcrack generates at WC/WC grain boundary, and may be blocked by interlaced fine-clubbed grains during extending, which induce the intergranular pulling-out. Due to the pulling-out mechanism, fracture-extend energy is greatly expended, thus bend strength is increased. The wear mechanism is groove wear and spalling of WC grains.

热机械合金化合成的WC-Co硬质合金比传统方法制备的同类WC合金具有更高的强度，其机理是：热机械合金化合成的WC合金具有交替排列的短棒状组织，在三点弯曲试验中，微裂纹萌生于WC/WC晶界位置，受到交错排列的短棒状晶粒的阻碍，裂纹扩展以短棒状晶粒的拔出方式进行，极大地消耗了裂纹扩展的能量，从而提高了弯曲强度；合成试样的摩擦磨损过程以犁沟磨损和WC颗粒的剥落为主要特征。
