再发生

The strengthening effect is attributed to recrystallization and the shape of pores during heat-treatment at 1800℃.

在1800℃真空热处理过程中发生的碳化硅再结晶以及气孔形状的变化，是其强度较高的主要原因。

Vascular endothelial growth factor is an important angiogenine. There is accumulating evidence shows that expression of VEGF in mature chondrocyte can promote cell redifferentiation and caryocinesia activity. VEGF plays a key role for chondrocyte to survival and proliferation during the chondrogenesis.

对成熟软骨细胞分泌表达蛋白的研究发现，软骨细胞表达一定水平的VEGF以提高软骨细胞有丝分裂活性并促进其再分化，在软骨发生发育过程中，对软骨细胞的存活与增殖起着重要的作用。

The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells. In the presence of auxin, the parenchyma of the leaf gap at the node is initiated firstly, then, develops blastemata that form buds in a cluster on the node without callus. These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明，茎段和叶片启动形成愈伤组织，其不定芽通常发生在愈伤组织的周边区，茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂，不形成愈伤组织而直接器官分化成芽原基，并在节结处产生一圈成簇的不定芽，表明元宝草不同部位的细胞启动及器官分化调控存在差异。

Our concern here is with situations in which such a redistribution takes place.

我们在这里要关心的就是会发生此类财富再分配的情况。

Because attraction between agent and reagent at all instants varied, with inverse proportion of increase and decrease, with incessant circular extension and radial reentrance.

因为起作用者和被起作用者之间的吸引力无时无刻不在发生着变化，而这又与持续不断的环状扩张和放射再突入的增减形成反比例。

The key to making code reentrant is to ensure mutual exclusion whenever accessing global variables or shared registers.

使代码可再入的关键在于确保在访问全局变量或共享寄存器时互斥现象发生。

Although we are still betting on reflation, we think the non-manufacturing data will need to pick up before this happens.

虽然现在我们还在对通货再膨胀进行打赌，但是我们认为，在发生这种情况之前，有关非制造业的数据还需要上扬。

Results: The 45 patients were followed up for 6 to 18 months, the fracture was healed without complication of vascular and nerve injury, shoulder function recovered completely, no steel plate loose and break, no refracture.

结果：45例得到随访，随访时间为6～18个月，骨折均愈合，无神经血管损伤并发症，肩关节功能完全恢复，无钢板松动、断裂和再骨折发生。

PMMA is the most used lesion filling at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage; Bolster for self-replacement can rebound vertebral body height, and Balloon-PKP and Sky-PKP can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used.

PMMA是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用造影剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；术前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂且价格昂贵的球囊－PKP及Sky-PKP；进行PVP时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

聚甲基丙烯酸甲酯是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用对比剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；成形前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂及价格昂贵的球囊后凸成形及骨膨胀椎体后凸成形；进行经皮椎体成形时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
