不平均的

A new approach to eliminate the ranges dependence based on angular frequency shifting in space domain was presented, in which, the nonhomogeneity of clutter is removed and the blind area of target detection is reduced due to the fact that the clutter of all the compensated range cells in every channel is moved to the place of the clutter of the desired cell by the different angular frequency shifts being added into spatial data along all Doppler channels for every compensating range cell.

第七章针对非正侧视相控阵机载雷达，由于杂波在距离上呈现出严重的非均匀性，尤其是在近程这种依赖距离的杂波谱呈现的非均匀现象更为严重，使得用于计算自适应权的协方差矩阵不可能直接由距离单元数据统计平均来估计得到，否则STAP处理及其降维技术难以获得理想的杂波抑制性能和目标检测性能，甚至恶化。

But to keep it simple, you can't reach the desired average speed under the given circumstances.

但是简单的说，在设定的条件下你是不可能达到理想的平均速度的。

1The nanocrystalline TiO2 film is prepared by sol-gel and appearance of the film is observed by SEM. The X-ray graph shows the film has lots of anatase and a few rutile TiO2, but does not have brookite TiO2. The average diameter of particle is 25nm according to Scherrer formula.

采用溶胶-凝胶法制备了纳米晶二氧化钛薄膜，通过扫描电镜观察了其形貌，X射线衍射表征显示出制备的薄膜具有大量的锐钛矿晶型和少量的金红石晶型，不含有板钛矿晶型，根据Scherrer公式计算出薄膜的晶粒的平均尺寸为25nm。

The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。

The main thing is hitting, but you need to get better at everything to play in the big leagues. You need to run, you need good hitting and you need the defense, too. I need to work on everything. I'm not a power hitter, but I want to hit for a good average. Maybe I'll hit in the second-hole, so I need to be good at bunting and moving runners over. That's my job, so I want to be good at it.

最主要的是打击，但是，要进入大联盟你在每个方面都要更好，你要跑得快，你要打的好，你要防守好，我要在每个方面都努力，我不是强力打者，但我想要能打出平均水准，将来，我也许会定位在第二棒，所以，我要有好的短打能力，推进跑者的能力，这是我的工作，所以，我想在这部份有很好的表现。

Berkshire past rates of gain in both book value and business value were achieved under circumstances far different from those that now exist. Anyone ignoring these differences makes the same mistake that a baseball manager would were he to judge the future prospects of a 42-year-old center fielder on the basis of his lifetime batting average.

过去伯克希尔真实与帐面价值成长的背景，与现在有很大的不同，若搞不清楚其间的差异，就好象是一位棒球教练在判断高龄 42 岁的中外野手未来潜力时，以他一生的平均打击率作为判断依据。

In this method, the outlier's density is considered smaller than the average density of data set and the none-outlier's density shouldn't decrease with its closed interval compression.

该方法提出了孤立点对象的密度要小于数据集的平均密度；非孤立点对象的密度不应因为封闭区间的收缩而减少。

EC Office of the second floor, something the average length 638 meters, 155 meters broad at its widest point north and south, a total area of 92,172 square meters, lawn area 36,000 square meters, the Green Square area of the total area of 40.31 percent, followed by drizzle in the Can smell in the air, in grass, under the scorching sun, will not have Zaore feeling, more than 6,000 pots of cockscomb, placed in a lawn like a small edge in the faithful guardians of the turf guarding the peace; 28 1 m high white Continental large flower pots stand at the rally on the east-west border, quietly played an "honor guard" role.

统办二号楼，东西平均长638米，南北最宽处155米，总面积92172平方米，其中草坪面积3.6万平方米，绿化面积占广场总面积的40.31％，在绵绵细雨之中能闻到芬草的气息，在炎炎烈日之下，也不会产生燥热感觉，6000多盆鸡冠花，摆放在草坪边缘像一个个小小卫士在忠实地护卫着草坪的安宁；28个一米高的洁白欧式大花盆伫立在集会区东西边界上，悄悄地扮演着"仪仗队"角色。

The optimization methods of database SQL query were studied and some available query optimization Methods were given out as follows: The incompatible data type should avoid to be used; More redundancy search parameters should be given as join condition in join query; In some condition, the number of note hitted to target was estimated by optimizing implement using the average density; Some other maths operating symbol should avoid to be used as condition parameters in WHERE clause; Some operating symbol and its sentence should avoid to be used also; When the cluster function was used,the WHERE clause should be paied attention to more,and so on.

作者单位：（重庆工学院商贸信息学院，重庆 400050）摘要：数据库SQL查询语句的优化，须注意：避免使用不兼容数据类型；连接查询中应多给连接条件提供一些冗余的搜索参数；某种条件下优化器只能使用其平均密度以估计命中的记录数；避免对WHERE子句中条件参数使用其它数学操作符；避免使用某些操作符及相应语句；聚簇函数的使用应注意WHERE子句。

On defining the conditional threshold of discretized density evolution, a method for designing the time-invariant quantized decoder with finite levels, which can approach the optimal time-varying one and hence the continuous decoding, is proposed.

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
