This paper applies simulation and actual data to make a comparative analysis of the effects of the four different references:average reference,linked mastoids reference,Cz reference and zero reference realized by the recently-developed REST(reference electrode standardization technique) for calculating the center of mass of EEG.

针对脑电头皮电位质心的计算问题，用仿真和实际数据计算比较了平均参考、连接耳参考、头顶参考和新近出现的近似零参考技术方法的差异，结果表明，采用REST可使得电位质心的计算误差在多数情况下更小。

In the third and the fourth taches, people with their eyes covered by red cloth strip to pursue an heart-to-heart intercourse.

第三和第四环节都是在眼睛被红布条蒙上的状态下进行的，意在追求一种心与心的交流。

In addition, the flash point in the spy must be noted that the pace of opening to get faster, when you came bunker, even if your heart with the goal of quasi-poor months thousands of miles away, it must be the first time off guns, Regardless of hit or not, immediately flash back bunker, if you are in life, then adjust the location of the prospective heart, ready to attack next.

另外，闪狙中有一点一定要注意，就是开抢的速度一定要快，当你闪出掩体，就算你的准心与目标差个十万八千里，也务必要第一时间甩枪，不论打中与否，马上闪回掩体，如果你还有命在的话，调整准心位置，准备下一次攻击。

I do not know Yuandufushu or Yuantianyouren, it can not be the scorching sun drying my cold heart, cool thoroughly, no Qudu the courage and the capital, dare not look forward to the next results, gambling, I lost All, gambling, I do not have the courage to find the heart gamble, I know that a White Piaoxiang bar where the wind and drift!

我不知道要愿赌服输，还是怨天尤人呢，烈日无法晒到我冰冷的心，彻底的凉了，再没有去赌的勇气和资本了，不敢期待下一次的结果，赌，让我输掉了一切，赌，让我没有勇气去寻找心的赌注，我这一张白纸吧知道飘向哪里，随风而飘！

To investigate the the body shape strength and kinematics thateffects sprint expert performance 17 healthy male sprinters weremeasured using SongxiaM9000 high speed vidicon in the field; body shape of sprint athlete were tested by steel rule; Meanwhile shoulder were tested at 60, 240and360 deg/sec velocities ; lower limb were tested at 60, 240 deg/sec velocitues using Biodex-II tesing and rehabilitation system in the laboratory This research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theoryThe result show that (1) The results of correlation indicate that 100M performance related to the shoulder fast flexion torque and hip flexion/extension torque^ ankle fast dorsiflexion torque ;(2) The upper arm relaxing enclose and lower limbs length effect 100Mperformance;(3) The biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100M performance.

使用松下M9000高速摄像机对100米跑动过程中的运动员进行录像，同时测试短跑运动员100米成绩，利用爱捷录像分析系统获取运动学参数；用人体测量尺测试短跑运动员的肢体围度；同时采用Biodex-Ⅱ型等动测力及康复统，测试运动员上肢肩关节及下肢髋、膝、踝3个关节的等速屈伸肌力。在角速度60°／s、240°／s和360°s下测试肩关节等动向心收缩肌力；在角速度60°／s9慢速和240°／s及120°／s下测试下肢3关节等速向心及离心肌收缩肌力。分析肢体围度、各关节肌肉力量和运动学参数与100 影响河北省二级以上短跑运动员专项成绩的因素。一身体形态、力量素质和运动学参数米成绩的内在联系，为合理制订短跑力量训练和完善短跑理论提供理论依据。结果表明；肩带肌群肌力矩确实与100米成绩呈显著高度相关，同时髓关节屈伸力矩比、踝关节背屈力矩与100米跑成绩呈显著中度相关，可能《是影响100米的因素之一。（2）上臂紧张围、上臂放松围与100米跑成绩呈显。著中度相关；最大肩关节伸角、肩关节摆动幅度和最大肘关节伸角与 100 米成绩呈显著中高度相关。

Lonely ,the Soliloquize of youth; desolated ,the solitary life ; Injustice ,the condition of let alone ;reasonable,the sadness loney.all this had been covered with sunshine of glitter and golden,any unhappiness and sad sorrow will wave between the lines .we always want to remain energy to study the behind things of the youth ,the persue,the hopeless.heart's free ,words are free .

孤独的青春独语，寂寞的生命荒凉，冷漠闲置的委屈，独自伤悲的理由，一切的来去都镀上了灿烂而张扬的阳光，任何的沉重与心伤都在夏日的灼烧下变成澎湃在文字里的点点渴望。关于青春，关于追逐，关于迷惘，我们总想保留旺盛的精力去接隐藏在其后的命数。心是自由的。文字是自由的。

On the bases of heating up amethyst, smoky quartz and yellow quartz; observing the change of their color; determining their absorbency and drawing the absorbency curve in different temperature and on the bases of the results of atomic absorption spectrometry, we discussed the stability of the color centers in quartz crystal.

通过在不同的温度下加热水晶，观察加热后的颜色变化，测定不同温度下的吸光度。根据各色水晶吸光度曲线特征及其在不同温度下的吸光度变化，结合原子吸收光谱分析，探讨有色水晶中空穴心的类型和稳定性。

The vast immensities of the universe do not fit in their little minds, so they bring them down to size.

浩淼无边的宇宙都盛不下他们小小的心，这些心把这宇宙变小了。

Compared with traditional method by solving a Jacobi matrix, calculating account is greatly decreased because only displacement and center of buoyancy need computing while those elements of waterline plane are not required.d Based on the research mentioned above, the paper presents the computer programmes of compartment definition, free surface effection, and some modules of the programme of the intact and damaged stability calculation.

与传统的拉格朗日乘子法相比，该优化方法公式推导简单，而且每次迭代只需计算水线面以下的排水体积和浮心坐标，不需计算水线面上的面积、漂心、惯性矩等要素，计算方法直接简便。 4在以上理论研究的基础上，开发了舱室定义，自由液面修正的计算机软件；编制了船舶完整、破损状态下的浮态、稳性计算的部分模块。
