The I-V characteristics of the diodes with 100μm diameter indicated that as the densities of V-defects on GaN films increased from 4.1×105cm-2 to 1.03×107cm-2, the Schottky barrier height decreased from 1.44eV to 1.19eV and the reverse bias leakage current at -1V is increased sharply from 10-10A to 10-7A . Further studies on a single V-defect using conductive atomic force microscope demonstrated that the value of forward current biased at 8V at V-defect side-walls appears to be one order higher than that of plain region, indicating that the conductivity mainly occurred at the side-walls of V-defect.

实验结果发现，随著V型缺陷密度由4.1×105cm-2增加至1.03×107cm-2，在氮化镓表面蒸镀镍金属所制成直径为100μm的萧基元件之所属能障从1.44eV下降至1.19eV，而且在-1V的操作下反向偏压漏电流从10-10A急遽的攀升至10-7A；为了了解V型缺陷对厘米尺寸n-GaN萧基元件电流传导机制之影响，我们进一步的利用导电原子力显微镜(Conductive Atomic Force Microscopy， C-AFM)，特别针对单一个V型缺陷进行微观电性之量测。

The reconstruction of large chest wall defect should be required divided management according to the location, region and degree of the defect. There are different flaps for covering soft tissue defect. Latissimus dorsi muscle flap with many advantages is the first choice.

结论巨大胸壁缺损需要分层修复，胸廓缺损可以用鈦网或聚丙烯网片修补，软组织缺损需要根据缺损部位、大小和范围及周围组织情况选择不同的修复方法。

However, vascularized bone autograft can't provide suitable donor for big mass bone defect, large segment defect and bone defect with joint because of limitation of quantity, size, shape etc of donor. So, people thinks of vascaularized bone allogeneic transplantation .

不过，因受供体数量、规模、形体等因素的限制，对于大块、大段以及包括关节的骨缺损，带血供之自体骨移植，颇有力不从心之感，而同种异体骨移植的实行，似可提供一种新的、有效的手段。

The micro mechanism considers that the inclusion in material, called micro defect crack, is the nucleus of internal crack initiation, interaction, between the stress field of the micro defect crack tip as loading and strain field of crystal lattice caused by crystal point passim (as vacancies or interstitial atom, H, O, N et al), will trap the point passim, and cause the enrichment of point passim around the micro defect crack.

其中疲劳裂纹内部萌生的核心是材料中的第二相粒子、夹杂物或微空洞，称为微裂纹；而微裂纹的长大是材料中间歇原子或空位等点缺陷在微裂纹尖端富集沉淀的过程，微裂纹的长大速率受到点缺陷富集扩散速率和疲劳载荷的双重影响。

The influence of the defect on the torsional stiffness and the stress distribution are calculated and analyzed by finite element method. The defect widths range from one-tenth of the femur outer diameter(0.1D) to (0.3D), and defect lengths range from 1D to 5D.

计算结果表明：骨缺损长度为D时，对股骨扭转刚度和剪应力分布的影响较小；骨缺损长度从2D增至4D时扭转刚度急剧减小，而且剪应力的最大值位于骨缺损中心。

According to the corneal thickness measured, a 7.0mm Hessburg-Barron corneal trephine was used to incise cornea into different deep defect in respective experimental group and placed 7.75mm SIS implant over the corneal defect.The implant was continuous sutured over the defect.The reaction of white rabbit corneal was observed and recorded everyday within postoperative observation period constituted 105 days.

根据所测量的家兔角膜厚度，使用直径7mm的HessBurg-Barron负压环钻分别对三组实验家兔的角膜植床取不同的深度，植入直径为7.75mm猪小肠黏膜下层，并将其连续缝合于植床上。

DATA SYNTHESIS:①Technical choice of gene therapy for bone defect: Human bone morphogenetic protein was the most often used objective gene in the gene therapy for bone defect at present, which had been identified in the models of rabbit, murine, caprine and dog in the application of plerosis of bone defect.

资料综合：①基因治疗骨缺损的技术选择：人骨形态发生蛋白基因是目前骨缺损基因治疗中应用最多的目的基因，已在兔、鼠、羊和狗模型中证实其对骨缺损的修复作用。

Mallory trichrism staining exhibited light blue samples. Eight weeks following repair, CT showed round blunt defect edges in the coronal position, which had bony pustute connection with gel materials. Density at the defect region significantly increased. 3D reconstruction suggested that defects became small. After hematoxylin-eosin staining, abundant fibrous connective tissue appeared in defect regions, with bony tissues. Mallory trichrism staining revealed that maroon mature bone tissues were found, surrounded by light blue chondroid tissues.
