Introduction : key forward direction back takeoff plum shooting from the space bar can be encountered enemy fire or obstacles to takeoff while shifting takeoff stationary or takeoff of aircraft and avoid life anqi otherwise reduce the value corresponding to pick up belongings scores increase 方向键前进后退起跳拾物空格键射击遇到敌人可射击或起跳遇到障碍要起跳同时移动或起跳躲避飞机和暗器否则生命值对应减少捡拾遗物分数会增加
The frequency analysis results show conclusions as follows : 1 . the relative valid spectral power is declined with the volume percentage of inclusions in terms of exponent curve and the tendency of negative direction is same to that of forward direction 当ly12铝合金细小夹杂物(小于0 . 16mm )的体积百分数从0 0 . 35时，在35 50mhz的频带范围内，超声波形的有效谱功率按近似指数曲线快速下降，沿相反方向检测时其变换趋势相同。
A patch antenna with air holes in the substrate has been designed . the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna . it is shown that the surface waves are significiently suppressed , the frequency bandwidth is improved , the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously ) 设计了一种基底钻周期圆孔结构的电磁(光子)晶体贴片天线，用fdtd方法并结合pml吸收边界条件对该天线进行了研究，结果表明本文所设计的基底钻孔型电磁晶体贴片天线取得了多方面的性能改善，与普通天线相比，基底中的表面波受到很大抑制，天线的带宽增加，远场方向图上天线的旁瓣和背瓣被明显削弱，向前辐射的增益由原来的12db增加到26db ，增加了14db ，比文献上报道的gonzalo等人的研究结果提高了4db 。
Image motion compensation ( imc ) is the key technology of high - resolution space camera . image motion speed is seperated into two vectors in image coordinate for the existence of the drift angle : the forward direction image motion speed and the crosswise image motion speed . in fact , drift angle control eliminates the crosswise image motion speed , so it is a part of image motion compensation 在空间照相，由于偏流角的存在，使得像移速度在像面坐标系存在两个分量：前向像移速度和横向像移速度，偏流角控制本质上是消除横向像移速度，因此，偏流角控制是空间相机像移补偿的一部分。
Considering the diffuseness of the n - n scattering in the forward direction results in an increased reaction cross section . and also the angular distributions calculated in the glauber theory including these two corrections are in good agreement with the experiment data . in the investigation of the halo nucleus reaction with a loosely bound structure , one has to consider the strong spatial correlations among its constituents 考虑了低动量转移的核子?核子两体散射在朝前方向上的弥散，使计算得到的反应截面增大，而且我们从弹性角分布的分析中得到考虑了有限力程修正的效应无论是在峰的位置还是角分布的绝对值都能更好地符合实验。

Then the reconstruction of curved surface of the covering parts was taken for an example , and the emphasis is laid on the identification and extraction method of the characteristic and the boundary , and the reconstruction method of curved surface . meanwhile it was given emphasis to the partition strategy of the data of point cloud , the forward direction design of the process of re , and so on 在此基础上，以覆盖件曲面重构为例，重点研究了点云数据的分块策略、曲面特征的识别和提取方法、曲面边界提取和曲面重构方式，以及反求过程中的正向设计等。
Different with the traditional ifog , light beams within mz - ifog transmit along the forward direction , which avoid the kerr effect noise and the interferometric noises brought by the backward scattering and reflecting light . mz - ifog also gains a high using efficiency of light source and a strong output signal . the principle of mz - ifog is analyzed 与传统sagnac干涉式光纤陀螺不同,此光纤陀螺结构简单,两路光信号采用前向传输,避免了后向传输光对光源的影响,也避免了后向散射、反射光带来的相干噪声以及光学kerr效应噪声,光功率利用率高,输出光功率大。
