C/1998 J1's track along the edge of the C3 field - where distortion is greatest - was problematic.

早期SOHO用在彗星上的天体测量方法还是很&老土&的：用彗星到太阳的方位角和距离来确定坐标。C/1998 J1 的轨迹是沿着C3视场边缘的，因此象差非常大，这就对旧方法造成了大麻烦。

Correlation and stepwise multiple regression between main chemical compositions of tobacco leaves and climate factors in different stages during the growing season in different tobacco-growing areas were performed under the same cultivation conditions.

根据纬度差异和地理方位，将我国主产烟区的7省12县分为南北两大烟区，采用统一栽培模式，对两区烤烟（Nicotiana tabacum L，）主要化学成分和大田生长期不同时段的气候因素进行多元相关及逐步回归分析，初步获得了两烟区烤烟化学成分的主导气候影响因子。

Imagine, if the good friend's real time and azimuth information are received in local bar and restaurant, that is an issue that makes a person cheerful certainly.

想象一下，假如在当地酒吧和饭馆收到好友的实时和方位信息，那一定是一件令人愉悦的事情。

Next, the user must replace azimuth news in time, so that invite a good friend,find oneself.

其次，用户必须及时更新方位信息，以便让好友找到自己。

In this paper,a three-level temperature control plan combining grade-control with PID control in terms of the range of temperature and time for the azimuth holding organ is proposed,and the parameters is optimized based on genetic algorithm.

The radar find and track the objects. As the same time, the azimuth and height information of the object will be sent to electronic collimation through UART.

雷达系统对空搜索，发现和跟踪目标，并将目标的方位、高低等信息通过串口传给电子瞄准镜系统。

After comparing the time domain approach of estimating azimuth and slowness in the f-k method with the frequency domain, it is shown that the time domain approach actually is not less accurate or efficient than the improved frequency domain approach, and in the case of signal-to-noise ratio is very low, the results obtained from the time domain approach are more reliable.

进一步对在时域中直接估算信号方位角和慢度的一种算法进行了分析，比较发现时域方法的计算速度和精度都不低于频域方法，且在某些低信噪比的情况下，前者可以给出更可靠的结果。

The given algorithm is simulated in various swaying conditions and compared, with the classical gyrocompassing approach The simulation results indicate that this method effectively improves the alignment performance, and the alignment time of azimuth is shortened by 50% as compared with that iu the gyrocompassing approachin the sam...

给出的算法在几种不同的晃动条件下进行了仿真计算，并和经典的陀螺罗经对准法作了比较。结果说明这种方法有效地改善了捷联惯导系统在晃动条件下的对准性能。在同样的模拟环境下，与罗经对准法相比，方位对准时间缩短将近一倍。

The constraints of the missile flying with SAR at the flight time are built, and the missile command acceleration is used as control variables to set up the objective function about the dwell time and the desired azimuth resolution. The control variables are optimized using the genetic algorithm, and an optimal trajectory is gotten.

首先建立了弹载SAR条件下导弹飞行的约束，然后以导弹指令加速度为优化变量，构造了与方位分辨率和波束驻留时间相关的目标函数，采用遗传算法进行寻优，设计得到了弹载SAR平台的优化弹道。

Because the scatterers at different range cells may have different Doppler characteristics, the range migration correction for moving ship is completed by coarse and fine correction procedures. The compensations of second and higher order phase terms are implemented in "range frequency - azimuth time" domain.

根据船体上不同距离单元散射点多普勒历程可能不同的特点，采用粗校正和精校正相结合的方法在距离频率-方位时间域进行二阶和高阶相位补偿，完成运动舰船目标的距离徙动校正。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
