WANG Lang-ping, TANG Bao-yin, WANG Xiao-feng, WANG Song-yan, LIU Ai-guo, TIAN Xiu-bo (National Key Laboratory of Advanced Welding Production and Technology, Harbin Institute of Technology, Harbin 150001, China)Abstract: In order to increase the peak depth of nitrogen atoms during the nitrogen plasma ion implantation of Ti-6Al-4V alloy, the rare earth metal yttrium was used to increase the implantation and diffusion depth of nitrogen atoms. In the experiment, the yttrium ions were implanted under the voltage of 20 kV firstly, and then the nitrogen ions were implanted under 30 kV.

According to nitrogen and phosphorus contents in grain, leaf and stem of wheat parent materials, 133 wheat parent materials were divided into nitrogen high-efficient parents, low-ability parents in absorbing nitrogen and nitrogen low-efficient parents and team were also divided into phosphorus lowefficient parents, phosphorus-wasted parents and phosphorus high-efficient parents, cluster analysis was adopted in the paper.

根据小麦亲本材料子粒、叶片和茎秆的氮、磷含量，采用聚类分析，将133份小麦亲本材料分成了氮高效、吸收氮能力差和氮低效3类，和磷高效、费磷和磷低效3类，同时还筛选出了7个氮素利用效率和磷素利用效率均较高的亲本。

Based on the Minqin oasis Daejeon cotton irrigation district, systems research and analysis of cotton under different irrigation water and nitrogen coupling effect, the main conclusions of the pilot study are as follows:(1) The coupling effect of water and nitrogen under different furrow irrigation patterns shows that water and nitrogen application rate increased in the three furrow irrigation patterns will help improve cotton yield, but FFI limit the effects of water and nitrogen play, AFI and CFI not significant differences in the effects of cotton yield.

试验研究取得主要结论如下：(1)不同沟灌方式棉花的水氮耦合效应研究表明，棉花产量效应表明，三种沟灌方式增加施氮量和灌水量均有利于棉花产量的提高，但FFI限制了水氮效应的发挥，AFI与CFI的棉花产量效应差异不显著。

Although effects of nitrogen fertilizer on nitrogen accumulation and nitrate reductase in tobacco leaf had been extensively studied, impacts of nitrogen fertilizer on flue-cured tobacco leaf nitrogen metabolism in dry land and paddy field were not well documented.

试验采用裂区设计，以硝态氮和铵态氮两种氮素形态为主处理、5个供氮水平为副处理，在大田条件下研究了水田与旱地烤烟在团棵、旺长、脚叶采烤、腰叶采烤和顶叶采烤等5个生育期烟叶的总氮浓度、硝酸还原酶和谷酰胺合成酶活性的氮肥效应。

But when it came to different summer-sown maize, the straw of normal summer-sown maize absorbed less nitrogen absorption than grain did, while the straw of high oil summer-sown maize absorbed more nitrogen absorption than grain did. This it to say, high oil summer-sown maize need more nitrogen, when use N2, the nitrogen redundance was not happened, not like normal summer-sown maize.

但就各器官来说，普通夏玉米和高油夏玉米高氮时的表现有差异，前者全年籽粒化肥氮吸收量低于秸秆，而后者高于秸秆，表明高油夏玉米需氮量多，高氮时没有发生氮素冗余，而普通夏玉米却发生了氮素冗余，致使吸收的氮更多地残留在秸秆中。

Methods Fourty-seven cases of Pilon bone fracture were were performed with typing according to Ovadia and Beals standard, and Type Ⅰ was used plaster external fixation; Type Ⅱ was used the calcaneum skeletal traction plus manipulative reduction; Type Ⅲ was used open reduction and internal fixation and Ⅳ,Ⅴ were used limited internal fixation combined with outside clamp stand, meanwhile the patient were introduced to functional exercise and efficacy was evaluated.

对47例Pilon胃折患者按Ovadia和Beals标准分型，Ⅰ型采用石膏外固定；Ⅱ型采用跟骨牵引加手法复位外固定；Ⅲ型采用切开复位内固定；Ⅳ、Ⅴ型均采用有限内固定结合外固定支架的方法，术后功能锻炼，并进行疗效评定。

According to the types, injury time and capitulum radii fracture or elbow dislocation associated with or not, 66 cases of UCPF were randomly divided into two groups: Groups I and Group II, which were treated by internal fixation alone and by comprehensive therapies, such as internal fixation, external bracket fixation and the external and intern...

随访 1～ 2年，结果显示内固定加外固定支架术后早期锻炼并配合中药内服外敷外洗的疗效优于单纯内固定组，两者比较有显著性差异(P 。0 5 )。表明内外固定结合早期自主功能锻炼，中药早期活血祛瘀、消肿止痛，中后期舒筋活络、软坚散结，配合外敷外洗，能使肘关节达到既稳定又能最大限度地恢复功能的目的。

In comparison with traditional rigid fixation, the lumbar "U" shape dynamic fixation system may be a better fixation instrument for the lumbar degenerative disease, which can decrease intervertebral disc stress and prevent intervertebral disc cataplasia of the adjacent segment.

腰椎"U"形弹性内固定与刚性内固定相比，术后能明显降低邻近节段椎间盘内应力，有利于减少和预防邻近节段退变，有望成为进行腰椎内固定较好的一种装置。本文由中国论文范文收集整理。

ConclusionIn comparison with traditional rigid fixation, the lumbar "U" shape dynamic fixation system may be a better fixation instrument for the lumbar degenerative disease, which can decrease intervertebral disc stress and prevent intervertebral disc cataplasia of the adjacent segment.

结论腰椎"U"形弹性内固定与刚性内固定相比，术后能明显降低邻近节段椎间盘内应力，有利于减少和预防邻近节段退变，有望成为进行腰椎内固定较好的一种装置。

the pathologic basis on ouurence of cubitus varus is the collapse of medial humerus cortex caused by that the medial stress of fracture has been stronger than the lateral stress;the main reason for occurence of cubitus varus is the gravitational ulner deviation which has been caused by gravitational effect on distal end of fracture;The multilayer splintage is a elastic fixation system and a effective therapeutic method;The key to preventing cubitus varus is reasonable reduction and fixation and fixation and early exact x-ray appraisal.

结果：认为骨折的内侧应力较外侧强，使内侧骨皮质塌陷是产生肘内翻的病理基础：远折端受重力作用的重力性尺倾是产生肘内翻的主要原因；弹性固定系统的多层夹板固定，是有效的方法；预防肘内翻的关健是合理的复位与固定及早期正确的X线评价。
