There are many merits of autofrettage of the composite material barrel with metal inner. One of them is that it can increase the elastic-plastic strength limits and possesses higher anti-plastic failure properties than pure metal barrels.

对带金属内衬的复合材料身管，自紧有许多优点，一方面可以提高身管的弹塑性强度极限，且经处理后的复合材料身管比纯金属身管具有更高的抗塑性破坏能力。

A calculation model of radiation heat transfer between the pressure tube and calandria tube of TACR, which is based on grey body radiation model and electronic network method, has been established.

本文以灰体辐射模型和电网络分析方法为基础建立了TACR压力管和排管间辐射换热的计算模型，利用该模型计算了给定温度边界和热流密度边界的情况下，压力管和排管间的辐射换热能力。

Methods: 28 goats (total 56 tibia), 12-month-old,no limit on male or female, 15~18kg.24 goats of them were were divided into three groups — experimental group A: allograft tubiform bone with autoallergic cancellated bone stuffed in.

28只成年山羊(实验组24只，对照组4只)，12月龄，雌雄不限，体重在15～18kg，共56根股骨分四组——实验组A：同种异体骨管＋管内自体松质骨；实验组B：同种异体骨管＋管内脱钙骨基质混合自体红骨髓；实验组C：同种异体骨管＋管内重组合人工骨；对照组：单纯同种异体骨管。

This paper put forward a kind of optimization method based on genetic algorithms for bidirectional flow laterals diameter on sloping field. This method could get the optimal diameter and control criterion of irrigated quality such as average flow and uniformity. Meanwhile, the running control parameter such as the optimum crotched position and intake pressure of laterals could be determined.

提出了一种基于遗传算法的坡地双向毛管管径的优化方法，能获得毛管最优管径和灌水器平均流量、灌水均匀度等灌水质量控制指标，同时能确定毛管最佳分流点位置和毛管进口压力等运行控制参数。

Methods High frequency ultrasonography of normal cubital and carpal tunnel were performed in 30 healthy volunteers.

应用高频超声观察30例正常人的肘管及腕管的超声解剖并对20例肘管综合征、10例腕管综合征患者术前行超声检查。

The major etiology of cubital tunnel syndrome is chronic injury with sustained compression of ulnar nerve around elbow joint.

结论］肘部的创伤及慢性劳损可以导致肘管弓状韧带出现肥厚增生，引起尺神经卡压磨损，这是肘管综合征最常见的病因；其他病因还包括慢性骨关节炎，占位病变和先天异常；尺神经可被机械性卡压和磨损，出现慢性缺血缺氧，导致肘管综合征的发生；详细的体格检查和术前的肌电图检查是诊断肘管综合征的主要手段，在诊断时应注意该病与其他部位迟发性尺神经麻痹的鉴别。
