变体

Martensitic transformation is a kind of specific and valuable transformation in Ni - Al applied field.

镍铝合金中的马氏体相变是一种特殊的并且在应用领域有重要价值的相变。

It was also shown that the properties of the martensitic steel obtained by impact has been improved.

实验表明，冲击后马氏体相变材料的力学性能发生很大变化，硬度及强度可提高2倍，在一定应变率下冲击后，断裂韧性也有所改善，这对利用冲击相变改善材料性能有重要意义。

Increasing the milling time continually,α-Fe of monophase BCC transfer to FeC intermetallic compound.

从X-ray衍射谱的分析可看出，这是由于样品发生了相变，从单相体心立方结构的α-Fe固溶体向FeC金属间化合物转变。x=1的样品，经255h球磨后，样品成为单相Fe5C2金属间化物，它具有单斜晶体结构。

The cell vacuolar degeneration, membrane structural necrosis, mitochondrin edema, mitochondrin vacuolar degeneration and lysosome myelinization were found in the endothelial cells.

1胞核内也可见纳米细菌，细胞空泡变，膜性结构类似坏死，部分线粒体水肿，空泡变，溶酶体呈现髓鞘图像。

There were nanobacteria in the nucleus and intracellar and extracellar endothelial cells under transmission electron microscopy after co-culture. The cell vacuolar degeneration, membrane structural necrosis, mitochondrin edema, mitochondrin vacuolar degeneration and lysosome myelinization were found in the endothelial cells.

混合培养后的内皮细胞透射电镜观察见细胞间、细胞内均有纳米细菌存在，细胞核内也可见纳米细菌，细胞空泡变，膜性结构类似坏死，部分线粒体水肿，空泡变，溶酶体呈现髓鞘图像。

Based on the leave of Pistacia vera L..Qualitative and quantitative analysis of phenol from Pistacia vera L. and effect on cell ultrastructure of Pistacia vera L tissue.The extracting technology phenol content from Pistacia vera L.

本文以阿月浑子植株与外植体为材料，采用化学方法与色谱-质谱方法对阿月浑子中总酚以及酚类物质成分进行了定性和定量分析，并用透射电镜观察了外植体褐变的发生对细胞超微结构的影响。

A model describing the relationship between recovery stress and temperature is developed based on the modified Clausius-Clapeyron equation. A composite model based on the Tanaka model is used to calculate the thermal expansion strain of composite, and the relationship between the martensitic fraction and temperature. Results show that this relationship is nonlinear, affected by prestrain and the heating-cooling history.

利用Tanaka模型以及在Tanaka模型基础上所建立的复合材料的模型，分析了TiNi合金丝/Al基复合材料的热收缩应变，以及复合材料中TiNi合金丝发生逆相变过程中马氏体分数与温度的关系，结果表明马氏体分数与温度之间的关系并非近似线性，而是随着预应变的不同、加热冷却过程的不同而变化的，在具体的使用时应根据不同的情况具体分析。

The in situ investigation of the effects of stress induced martensitic transformation on fatigue behavior in TiNi shape memory alloy was conducted using a quester remote measurement system.

原位研究了TiNi形状记忆合金中应力诱发马氏体相变和逆相变对疲劳行为的影响。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

Results: Axial scanning including vertebral arch can show spondyloschisis and other signs. These contained widened or stenosis of the spinal canal, stenosis of he lateral recess, the double margin sign, deformity of the lateral recess, the double margin sign, deformity of the intervertebral disc, denegeration of the joint facet and thickening of the ligamentum flavum. Scotty dog sign were showed in images reconstructed along the direction of vertebralarch.
