Methods: We evaluated a consecutive series of intercollegiate athletes treated operatively with 4.5-mm cortical screw fixation for grade III syndesmosis sprains. At 1 week after surgery, patients were allowed to begin range of motion exercises, progressive weightbearing, and gradually return to full activity as tolerated. Outcome measures included time to return to full activity and, at final follow-up, the Sports Ankle Rating System scores.

The activities in different sections of the Gaoqing fault in the Huagou gas field were analyzed using 3D seismic data. The activities of the fault segment associated with the Huagou gas field were strong during the Guantao\|Minghuazhen period, while the activities on east and west sides of the gas field were weak at that time. The Huagou gas field is well corresponding to the strong activity segment of the Gaoqing fault on the plane. The process of gas migration in the Huagou reservoir is divided into two phases:(1)After mantle\|derived magmatogenetic gas including CO2, N2, and He entered the Gaoqing fault, the gas migrated to the top of the fault by the action of buoyancy or pressure, then the gravitative differentiation occurred. For the top of the fault is closed and both sides of fault is sealed, the gas assembled to some degree in the Gaoqing fault;(2)When gas was accumulated at a large scale in the Gaoqing fault, the gas migrated towards the reservoirs along the two sides of the fault and was accumulated in sandstone.

利用三维地震资料，对济阳坳陷花沟CO2气藏区高青断裂走向上不同区段的活动性进行了分析，指出：花沟CO2气藏所对应的高青断裂区段，在馆陶组—明化镇组沉积时期活动性强，而气藏的东、西两侧，馆陶组—明化镇组沉积时期断裂基本上不活动；花沟CO2气藏与馆陶组—明化镇组沉积时期高青断裂活动性强的区段在平面上有着良好的对应关系；花沟CO2气藏的运聚过程分为2个阶段，在第1阶段，幔源岩浆成因的CO2、N2和He等气体进入高青断裂后，在浮力或压差作用下向断裂顶端运移，并发生重力分异，由于断裂顶端封闭、两侧封堵，CO2、N2和He等气体在高青断裂中实现了一定程度的聚集，而在第2阶段，当CO2、N2和He等气体在断裂中聚集到一定程度，便在压力驱动下向断裂两侧砂岩储层运移，并在其中聚集成藏。

Then, according to phase space reconstruct technique from one-dimensional and multi-dimensional time series, the quantitative criterion and rule of system chaos which combine neural network, analyses, computations and sort are conducted on EEG signals of five kinds of human consciousness activities. The author finds that statistic results of the determinism computation in time series indicate that chaos characteristic may lie in human consciousness activities, and central tendency measure is consistent with phase graph, so it may become one division way of attractor; approximate entropy of different subjects exists discrepancy; correlation dimension and Lyapunov exponent of different consciousness activities indicate that attractors of human activities are all fractional; nonlinear quantitative criterion and rule, which unites neural network, can distinguish different styles of consciousness activity in principle, and the result of sortation takes on that consciousness activity type of arithmetic is distinguished more easily than that of abstract.

采用一维与多维时间序列相空间重构技术和系统混沌的定量判据准则，结合神经网络，对五种思维作业方式的脑电信号进行了分析、计算与分类，发现确定性计算的统计结果表明人类的意识活动中可能蕴含混沌特性，中心趋向测量(Central Tendency Measure，CTM)与相图吻合较好，可作为EEG吸引子的区分方法之一；功率谱分析反映出单个受试者的各种意识形态的差异很小，但是不同意识活动谱中的活跃频段还是略有差异的；个体之间的近似熵存在差异，同种状态下近似熵大的人可能具有更好的创新性；关联维数和Lyapunov指数的计算结果表明大脑的运动落在具有分维的奇怪吸引子上；非线性量化方法与神经网络相结合，可对人脑思维活动进行较好的分类，并且从分类结果来看数理计算类思维活动较抽象类思维活动有着更好的区分度。

The testis index, testis volumes were same as the annual changes of testis mass. The curves of annual variation were all unimodality.2 The spermatogenetic cycle of Myospalax cansus comprises seven stages with significant features: Stage I , from February to April, the testis were at the stage of spermatogonia proliferation. In this period, testis index and the number of spermatogonia began to rise. Other spermatogenic cells had not yet formed; Stage II to III, from March to April, primary spermatocyte meiosis period. The testis index was highest in this stage, and spermatogenic cells were in spermatocyte stage, the primary spermatocyte meiosis generated to secondary spermatocyte; Stage IV, from April to May, spermatocytes continued to split, germ cells appeared in seminiferous tubules; Stage V, in May, sperm formation, spermatids of seminiferous tubules were transformed to spermatozoa, a large number of sperms existed in the lumen; Stage VI, spermatozoa emission period, from May to June, testis index were a significant drop and mature spermatozoa excluded gradually; VII, the testicular activity ceased basically from July to September, November to January of the following year, the spermatogenic activity ceased completely. Therefore, Myospalax cansus are animals of seasonal reproduction, spermatogenesis cycle is discontinuous type.

睾丸系数、体积和重量的年周期变化规律一致，变化曲线呈现单峰型。2甘肃鼢鼠雄性生殖腺的年周期活动由7个特征明显的时期构成：Ⅰ期，2～3月份，精原细胞增殖期，睾丸系数开始上升，精原细胞进行有丝分裂，其他生精细胞尚未形成；3～4月份为Ⅱ～Ⅲ期，初级精母细胞成熟分裂期，睾丸系数达到最大，生精细胞大多处于精母细胞阶段，初级精母细胞减数分裂生成次级精母细胞；Ⅳ期，4～5月份精母细胞继续进行分裂，精细胞在生精小管内出现；Ⅴ期，5月份，精子形成期，曲细精管中精细胞变态成精子，在管腔中存在大量的精子；Ⅵ期，精子排放期，5～6月份，睾丸系数显著下降，成熟精子从生精小管上脱离，逐渐排除；Ⅶ期，精原细胞停滞期，7～9月份睾丸生精活动基本停滞，11～翌年1月，生精活动完全停止。

In 1999, we began to sort out the research results and carry out the second-round experiment. The original aim of this research project is to resolve the problems in actual situation and sets up a bridge between problems and experience, so that educational research can play a particular role in the teaching practice. It is a dynamic process of practice—problem settling---reparctice---problem resettling.

本课题的研究本身是一项行动研究，是由实际工作人员和研究者合作进行的，将实际工作者的实践活动与研究者的学术性探究活动相互联系的一种研究活动，具体而言是在上海市实验学校领导的支持下，由学校老师共同参与共同进行的一项研究。1997年度和1998年度学校连续两年将小学和初中阶段进行的综合模块课程研究立为学校的科研项目，1999年度课题进入研究成果的整理阶段并开始进行第二轮实验。

Beijing, the capital of the Preparatory Committee for the 60th anniversary of National Day spokesman told reporters that, to ensure that the national day celebrations proceed smoothly, the scene of the celebration of the organization of running-in, since the August 29 night to early this morning, in Tiananmen Square area has been included National Day mass demonstrations Festival special adaptive training exercises and military parade in the content of a special drill first National Day celebrations.

国庆60周年，首都演练开始新华网北京8月30日电首都国庆60周年北京市筹备委员会新闻发言人向记者介绍，为确保国庆当天庆典活动的顺利进行，现场磨合各项庆祝活动组织工作，自8月29日夜至今日凌晨，在天安门地区先后进行了包括国庆群众游行、联欢晚会专项演练和阅兵适应性训练等内容的首场国庆庆祝活动专项演练。

The analyzing aboved is made from earthquake's space distributing, periodicity, migration phenomenon, repetition, strength, frequency, b value etc., according to data of earthquake station net in Shaanxi Province and microseisms station net watching results in Xi'an area. 3 group faults which are NEE, NW and EW direction control earthquake activities in Guanzhong area. Epicenter depth mostly is 5-25km and in shallow-focus earthquake. Earthquake in east area of Guanzhong was stronger and weaker in the West in history. Fen-Wei earthquake belt showed more activity. Microseisms and small seisms is main movement in recent earthquake, it has 8-10years' period of movement and show the trend that they are strong in the West but weaker in the East. And frequency and biggest magnitude of earthquake is supplement each other. In next years earthquake frequency will lessen but strength enhance, about M4. It presumes there is earthquake climax period in Guanzhong area in 2040 and M5-6 earthquake is happened at that time.

本文在对关中地区区域构造及重磁异常特征的分析基础上，根据陕西省地震台网监测资料及西安地区微地震台网监测成果，从地震的空间分布特征、周期性、迁移现象、重复性、强度、频度、b值分析等方面，对区域地震活动特征、关中地区地震活动规律进行了分析研究，关中地区地震活动主要受北东—北东东向、北西向、东西向三组方向的断裂控制，震源深度多为5—25公里，均属浅源地震，历史地震表现为东强西弱，东部的汾渭地震带表现出较强的地震活动性，近代地震活动主要以微震或小震为主，存在着8—10年的活动周期，近期表现出西强东弱的趋势，地震的频度与地震最大震级呈互补关系，未来的几年间，地震频度会有所减少，强度会增大，将有可能发生4级左右的地震，推测在2040年左右，关中地区将进入地震高潮期，届时将可能有5—6级左右的地震发生。
