RESULTS ① rhBMP2/BCB used alone was capable of healing the defect in large part by 16 wk, with a similar repair process and mechanism to that seen with RBX;② use of rhBMP2/BCB in conjunction with vascularized periosteal graft exhibited stronger defect-repairing power, basically healing the defect by 8 wk. The repair process consisted of intramembranous and endochondral ossification that resembled the physiological repair during the fracture healing.

结果①单纯rhBMP2/BCB移植，可在16 wk使节段性骨缺损基本修复，其机制与过程与重组合异种骨相似；②rhBMP2/BCB与带血循骨膜联合移植，仅用8 wk即可修复骨缺损，其修复机制与骨折修复相仿，包括膜内成骨和软骨成骨两种机制。

Photonic quantum-well structures can be constructed by stacking 3 photonic crystals with the same photonic band gap and different defect modes. On condition that the defect mode of the PC in the well region is located into nontransmission frequency ranges of the PCs in the barrier regions, the confined photonic state appears and can completely transmit through the structure by tunneling. However, its transmission will be strongly prohibited due to vanishing of the photonic QW induced by shifting the defect mode frequency of either of the PCs in the surrounded regions to that of the middle PC.

把三块各带有一个缺陷的光子晶体结合起来，如果中央晶体的缺陷模处在两侧晶体的禁带中，缺陷模内的光波会受到两侧晶体的阻碍并被局域在中央晶体内，形成量子阱结构；若一侧晶体的缺陷模被移动到中央晶体缺陷模处，则只有一侧晶体阻碍在中央晶体缺陷模内传播的光波，量子阱效应完全消失，光的传输受到最大程度的阻碍。

The mechanisms of bone defect repairing by DBM+bBMP composite are realized by bone induction and conduction in the defect area, and its capacity of repairing bone defect is better than pure DBM. It is an ideal and effective osteogenetic implant substitute.

异体DBM复合bBMP材料通过骨诱导和骨传导两种方式修复骨缺损，其修复骨缺损的能力要优于单纯DBM材料，是一种较为理想，具有高效成骨活性的植骨材料。

BACKGROUND: Facial nerve defect seriously impacts the mental and physical health of patients as well as their quality of life. Pediceled neck muscle transplant and autologous nerve transplant have been used in clinical to repair facial nerve defect and restore the facial muscle function. However,there are disadvantages and limits of above methods which have restricted their wide application of them. It is a research hotspot for looking for a new material to repair facial nerve defect.

背景：面神经缺损严重影响患者身心健康及生活质量，临床采用较多的有带蒂颈肌移植术和自体神经移植术等修复面神经缺损，恢复面肌的功能，但上述方法均有其缺点和局限性，使其广泛应用受到限制，寻求一种新的修复面神经缺损的材料是目前研究的热点。

INTERVENTIONS: A full-thickness defect in articular cartilage was made on the femoral trochlear surface by a drill of 5 mm in diameter and 3 mm in depth. Rabbits were allocated into filling group(type Ⅱ collagen sponge was grafted into left keen joint defect) and control group(right knee joint defect site was set as control) according to random number table.

干预：在股骨滑车面钻孔为直径5 mm、深3 mm的全层关节软骨缺损，按随机数分为填充组(左膝关节缺损部位植入Ⅱ型胶原海绵)和对照组(右膝关节缺损部位作为空白对照)。

As to the defect divide,the thesis discussedfirst the problem of the most complex---design defect,and the focal point isdiscussing the new development about design defect in the Restatementof Torts,which means that in the standard of judgment we should adoptnegligence instead of strict liability,and that in adducing evidence TheReasonable Alternative Design should be put forward.

在缺陷的划分上，论文先论述了最为复杂的设计缺陷的问题，重点论述了美国《第三次侵权法重述》关于产品设计缺陷的新发展，即在判断标准上采疏忽责任而非严格责任，在举证上要求提出合理的可替代的设计问题。

Rabbits (48 laterals) were prepared as model of bone defect, divided into 3 groups, named complex group (24 laterals), in which, unilateral bone defect of 24 rabbits were implanted with cell + carrier complex; The rtificial bone group (12 laterals), in which, CPAB was implanted contralaterally;and blank control (12 laterals), in which, no any management was done contralaterally in bone defect of 12 rabbits.

24只兔(48侧)制作成骨缺损模型，分为3组，复合物组(24侧)，24只兔一侧骨缺损植入细胞+载体复合物；人工骨组(12侧)，12只兔对侧植入磷酸钙人工骨；空白对照组(12侧)，12只兔对侧骨缺损不作任何处理。

The results show that amplitude of defect signal is adversely affected by lift-off variations,but phase difference between defect signal and lift-off loci is almost unchangeable.After analyzing the characteristics of the phase difference with the chang of frequency,a conclusion that defect signal is approximately vertical to lift-off noise at a well-selected frequency is obtained.

结果表明提离增加会显著降低缺陷信号的幅值，但并不影响缺陷信号和提离轨迹之间的相位差，通过分析相位差随检测频率的变化规律发现：存在一个合适的频率可使缺陷信号和提离干扰之间出现90°的相位差。

Chapter two was developed the fundamental theorem of speech enhancement, in which the characteristics of speech versus noise, and the model of the speech formation as well, were analyzed. By Combining the conventional evaluating method for speech enhancement system with modern techniques, a new method was proposed, and an experimental system was eventually worked out.

本文以带噪语音为研究对象，开展了带噪语音增强的基础研究工作，从理论和实践上对语音增强的各种算法进行了深入而系统的研究，尝试了在原有谱相减法的基础上引入隐马尔科夫模型、矢量量化及人工神经网络等研究方法及手段并提出了相应的语音增强算法。

Speech recognition is one of the important contents of the speech signal processing, and how to increase the preciseness in speech recognition is the mainly intention of the speech recognition research.

语音识别是语音信号处理的重要内容之一，如何提高语音识别的正确率则是语音识别研究的主要目的。

I had a lovely dog named PiPi, he was one of my best friends.

我曾经有过一只小狗，它的名字叫皮皮，它很善良，它是我最忠实的朋友。

Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity.

我们猜测卵母细胞在不含丙酮酸的条件下老化的更快，并且卵丘细胞可能通过消耗不含葡萄糖的CZB中的丙酮酸从而促进卵母细胞老化。
