织缺损的修复，由于所涉及的学科多、方法复杂，故而至今尚无一种满意的修复方法。

DNA single strand breakages are more prone to be repaired than double strands breaks and DNA-protein crosslinks.

4PAHs和非烃组分诱导的细胞DNA单链断裂自发修复能力较强，而DNA双链断裂和DNA―蛋白质交联修复率极低。

Results IPS Empress2 was same as IPS Empress1 in color and shape of prostheses,margin sealing and second caries of a butments,IPS Empress2 was better than IPS Empress1 in fracture of prostheses sig nificantly (P＜0.05),IPS Empress2 all-ceramic bridges was better than po rcelain bridges with gold alloy in color of prostheses (P＜0.05),it was same as porcelain bridges with gold alloy in fracture of prostheses and shape of prostheses,margin sealing second caries of abutments.

结果 IPS E mpress2全瓷冠的颜色、形态、基牙龋患率、修复体的边缘密合度、边缘着色与IPS Empress 1无统计学差异，在修复体折断率方面IPS Empress2低于IPS Empress1(P＜0.05)， IP S Empress2全瓷桥在颜色方面好于金合金基底烤瓷桥(P＜0.05)，其他方面无统计学差异。

This paper discussed the existing fractions of nickel in natural soil, transformation of nickel fractions in soil and the effect of organic chelators on phytoextraction and biomass.

本文讨论了土壤中镍的存在形态以及有机螯合剂对土壤中镍形态的影响，并从植物吸收Ni的机制出发，阐述有机螯合剂对植物吸收Ni和植物生物量的影响，分析了植物修复的螯合诱导技术的一些局限性，并对植物修复螯合诱导技术提出展望。

The results show that from the interface to surface the microstructure of the cladded coating is composed of plane grains,tiny grains and fine dendritic grains. The two main compositions of Ni and Cr homogeneously distribute in the section.

结果表明，熔覆修复层的显微组织从界面往上依次由平面晶、细晶层和中部细小的树枝晶构成，主要元素Ni和Cr在截面内均匀分布，原有Cr层与熔覆层内的Cr元素呈连续状，构件修复区以外的铬层与基体的结合未受激光熔覆的影响。

Technology of galvanoceramic is a process of fabricating ceramometal restorations utilizing 99.9% pure gold copings by electroforming techniques, electrodepositing a metal onto a suitable substrate in specific electroforming apparatus.

金沉积烤瓷修复技术是指通过专用的电镀仪，利用电铸原理，在模型上电镀出含99.9％纯金的金沉积冠，然后在其表面进行烤瓷的修复技术。

Methods:The wounds of 131 patients （164 limbs）were thoroughly debrided and closed as early as possible.After the debridement, 107 limbs were treated with external fixation , 34 limbs with unreamed interlocked tibial nails, 11 limbs with steel plates , and so on.

131例（164肢）患者入院创面反复冲洗清创，早期修复软组织为主，提供软组织修复的初期稳定，选择合适的固定方式，外支架固定107肢，不扩髓绞锁髓内钉固定34肢，钢板内固定11肢，石膏外固定7肢等。

More broadly, demonising finance and bankers makes it politically harder to repair the financial system, which involves working with, and even rewarding, them.

从政治上来说，丑化金融业、银行业的高级从业者，会增加修复金融系统的难度，因为要修复金融系统，还是需要这些从业者的参与，甚至是给他们一些奖励。

They are all lack of skin appendages, such as hair follicle, sebaceous gland and eccrine sweat gland, and the "functional tissue engineering skin" can not be constructed.

表皮干细胞作为皮肤组织的特异性干细胞，与创面修复紧密相关，是维持皮肤新陈代谢的主要功能细胞和皮肤及其附属器发生、修复、改建的基础。

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。
