首先

First of all, let's try the very basics.

首先，我们从最基本的开始尝试。

First, basing on point halving, this thesis proposed a new efficient algorithm of computing kP lQ on an elliptic curve over the finite field with characteristic 2 and analyzed the computational efficiency. When the ratio I/M of inversion to multiplication cost is small, this new algorithm is about 5%～30% faster than the traditional algorithms.

首先，基于半点运算给出一种计算特征为2的有限域上椭圆曲线双标量乘法kP lQ的新算法并分析了效率，当基域上求乘法与求逆的运算时间的比值比较小时，新算法的效率比已有算法提高5％～30％。

Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

First, commonly used methods of flight segment volume forecasting are systematically elaborated, Then theory basis of support vector machine and its principle are introduced, support vector machine model is inferred, the support vector machines algorithm is studied.

首先，系统地介绍了航空运量预测中常用的预测方法，并对几种常用方法的特点进行了分析比较。

The first thing you notice are Zubin Mehta's sideburns, as he stands on the podium in a newly released 1977 video of the Los Angeles Philharmonic at the Dorothy Chandler Pavilion, about to give the downbeat for Mozart's Bassoon Concerto.

首先，你的通知是祖宾梅塔的鬓角，他站在领奖台上，在新发布的1977年影片的洛杉矶爱乐在桃乐斯钱德勒亭，大约使悲观的莫扎特的巴松管协奏曲。

First of all, I'd wanted a chance to work with Jack Canty and Ryan Bates for a while.

首先，我要通缉的机会，工作与杰克canty和瑞安贝茨了一段时间。

Firstly, the most important thing is to recognize the type of battle.

首先，最重要的事情是确认战场的类型。

Above all, when the member is evaluated, the system matchs automatically corrupt font of character bawdry key, if the library appears in member commment,middle term group cannot refer a success.

首先，在会员评价时，系统自动匹配污言秽语要害字库，若会员评语中出现库中词组则无法提交成功。

First, the formal representation of the search environment is established, the multi-UAV is modeled as a controlled system and the predictive model of the system is presented. Considering the uncertainty of the sensor measurement and the environment, a Search Probability Map is defined and the updating method based on Bayes formula is presented. Based on SPM, information gain is defined to measure the search effects and used to be the optimization object in the predictive horizon. By using of GA, the solution of the optimization problem is got and it is taken as the input of the controlled system.

首先，建立搜索环境的规则描述，然后将多个UAV建模为一个控制系统，建立系统的预测模型，考虑到UAV传感器测量的不确定性和环境自身的不确定性，建立搜索概率图描述搜索环境的不确定性，给出了基于Bayes准则的搜索概率图更新方法，继而基于搜索概率图定义信息增益来衡量搜索效果，并将预测周期内的优化目标定为最大化信息增益，采用遗传算法进行求解，得到最优解作为被控系统的输入。

Firstly,we put more emphasis on:when you read in your university,you ought to be absorbed in acquiring knowledge and skills.

首先，我们更多地强调：你在读大学时应该集中精力学习你的专业知识和技能以及所有文化课。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
