Thirdly , the air - air missile ' s model is studied , and set up guided missile motion equations that passes through the area of the down wash . using the preceding down wash distributing data , the fly situation and orbit changes in initial stages of the guided missile launch have been studied 再次，对空空导弹的模型进行了研究，并建立了导弹穿越旋翼下洗区域的运动方程，运用前面的下洗分布数据，研究了导弹发射最初阶段的运动情况和轨迹变化。
In the second part of this dissertation ( chapter 6 and chapter 7 ) , it is demonstrated that in low multiplicity sample , the increase of the fluctuation of event factorial moments with the diminishing of phase space scale , " erraticity " , are dominated by the statistical fluctuations 在非对心碰撞中，初始坐标空间中的方位角不对称性将导致末态粒子相对于“反应平面”的角依赖性。微观上讲，末态动量空间的大的各向异性来源于碰撞最初阶段的大量的再散射。
Through comparing xu zhi - mo with his contemporaries in the whole development process of new poetry , the author states that xu zhi - mo ' s poetry gift made him the first summit of the initial phase of new poetry and then analyzes the most distinct aesthetical features of his poems : the senses of gentleness and flexibility , charm and modality 摘要作者把徐志摩放在整个新诗发展过程中进行分析，通过把他与同时代的其他新诗人进行比较，说明徐志摩与生俱来的诗人禀赋使他的诗成为中国新诗最初阶段的第一个高峰，进而深入分析其诗歌最明显的美学特征：轻柔感、音乐感、形式感。
The observation that some components , e . g . endotoxin , are released at the same rate in two successive handling steps , and that others ( e . g . fungi ) are mainly released initially , shows that the exposure period to different components from the same material differs in duration 继续观察到，有些组成，例如内毒素，在连续两次实验步骤中释放速率是相同的，而其他(例如真菌)主要则是在最初阶段就释放到空气中了，此结果显示，同样材质的不同组成，其所暴露的时段是不相同的。
However , at the initial stages , because the development of wfms lack unified general standard and limited to the level of software at that time , the workflow products of different company have heavy difference such as the function , the support technology adopted , developing technology and the interface . so they ca n ' t be compatible each other nearly 然而，在工作流管理系统开发的最初阶段，由于缺乏统一的、普遍遵循的标准以及限于当时软件支撑技术的水平，导致不同公司的工作流管理系统在功能上、所采用的支撑技术上、开发技术上和接口上都呈现出非常大的不同，几乎彼此都不能兼容。
Previous studies looking at this topic may have failed to identify a link because they focused on women at least 6 weeks after their last menstrual period . by contrast , most miscarriages occur earlier in pregnancy , usually within three weeks of conception . in the study reported in the proceedings of the national academy of sciences early edition , levels of the stress hormone cortisol levels were measured in the urine during the first 3 weeks of 22 pregnancies 此前就这一课题进行的多次研究之所以未能成功确认两者之间的联系，其原因或许在于研究人员总是将注意力放在那些停经已达6周之久的孕妇身上，但大部分流产都发生在妊娠的最初阶段，通常是在怀孕开始后的3周内。
