On the basis of introducing the channel and system model of wireless optical communication,average bit error rate of uncoded and RS coded system with channel side information were analyzed,and compared with Turbo coded system from the following two aspects:received optical power and Log-amplitude fluctuation variance.

在介绍无线光通信信道及系统模型的基础上，推导了无线光通信未编码系统和RS编码系统在已知信道边信息条件下的平均误码率，从接收光功率和对数振幅起伏方差方面对RS码编码系统和Turbo编码系统的性能进行比较。

Expect for a few pittings,the N+1-implanted surface had a best fineness (average roughness Ra≈4.2nm), close to the unimplanted original surface.The N+2-implanted surface had a black dendritic area,and had a poorer fineness (Ra≈16nm).While in the N+10-implanted surface appeared a ripple structure,with the poorest fineness (Ra≈40nm).

但其表面形貌各异：N+1注入的表面除存在少量点蚀坑外，光洁度最高(平均粗糙度Ra≈4.2nm)，接近未注入前的原始表面(Ra≈3.5nm)；N+2注入的出现黑色枝状区域，光洁度次之(Ra≈16nm)，而N+10注入的则出现&波纹&状结构，光洁度最差(Ra≈40nm)。

The scheme can achieve high quality of unvoiced speech in 96bits/frame.

objective to investigate the treatment effect of wolter crook plate on distal clavicle fracture and acromioclavicular dislocation.methods thirty two patients underwent surgical repairs with wolter crook plate.results twenty seven cases were followed up for 12 months.according to karlsson,the excellent result was found in 19 cases;good in 8 cases;poor in 0 case.no complications such as infection,non union,plate failure,or redislocation after removal of the plate was found.conclusion the implant of wolter crook plate provides sufficient stability to allow active shoulder exercises immediately after surgery,which is worthy of clinical practice.

对32例锁骨远端骨折及肩锁关节脱位患者采用wolter钢板内固定治疗。结果本组27例获得随访，平均随访时间12个月，根据karlsson疗效评定标准：优19例；良8例；差0例。未出现感染、骨不连、钢板断裂以及内固定取出后再脱位等并发症。结论 wolter钢板固定能提供足够的生物力学稳定性，可允许患者进行早期功能锻炼，且肩关节功能恢复较好，有一定的临床推广应用价值。

In Canada, the differential was only about 20 percent and this approximated the average gap in other auto-producing countries.

在加拿大，唯一的差别是百分之二十左右，这近似的平均差距在其他汽车生产国。

The results showed that the hardness of CGHAZ is decreasing,bainite ferrite strip coarsens,the shape of M－A constituents transforms strip into block,its size becomes large,and its bulk extends, with increasing of t8/5.In addition austenitic,M－A constituents in γ grain boundary coarsens and manifolds with increasing of t8/5.They all deteriorate the toughness of pipeline.And the extended zone of impact fracture shows brittle.

结果表明，随着t8/5的增加，粗晶区硬度逐渐减小，贝氏体化铁素体粗化，且其间的M－A组元由条状转变为块状，平均弦长增加，体积分数增大，奥氏体晶界M－A组元增多变粗，管线钢的韧性恶化，抗裂性变差，冲击断口扩展区呈脆性断裂。
