I can't believe how bright the ejecta blanket is. 我真不敢相信那层残骸居然这么亮。
The expanding ejecta drive an outward-moving shock wave that races ahead of the ejecta into the interstellar gas ( bright outer rim). 膨胀的抛出物驱动着外行激波,领先于抛出物冲入星际气体(明亮的外缘)。

According to the shock theory, the ejecta produced by explosion form the pressure pulse, and it spreads in forms of either compression waves or expansion waves. 根据激波理论,爆炸产生压力脉冲并以压力波的形式传播,既有压缩波也有膨胀波。
Grain size analysis shows that the ejecta are composed mainly of fall deposit with an interbed of surge deposit, and the type of eruption is phreatomagmatic. 粒度分析表明,天池火山最近一次喷发物以空降堆积为主,夹一层薄层涌浪堆积,火山喷发类型为射气岩浆型。涌浪堆积碎屑物的分数维值为2.71。
In order more accurately to determine the mound shape of ejecta and use the directional blasting for various complex conditions, the author presents a simple mechanical model-whole throwing bits of rock move and fall with ballistic path. 在各种复杂条件下,为了准确地确定定向爆破抛掷土堆的形状,作者提出了一种简单的机械模型&整体弹道抛掷法。
Based on historical records, stratigraphic correlation and features of the deposits, it is estimated that the ejecta are the product of 1903 AD eruption. 根据历史记录、地层层序关系、堆积物特征的综合分析,推测堆积物的形成时间为公元1903年。
The projected radial velocities of ejecta are 120 and 97 m/ s. 两个喷出物的径向投影速度分别是120和97m/s。
Seeds from ejecta spit out by bats; 被吐出的果渣中的种子;
The experimental result shows that the axial velocity of back ejecta target material is faster than 2.9 mm/ μ s, while the simulation gives a velocity of 9.7 mm/ μ s under the ideal conditions. 实验表明,钽金属靶在强流脉冲电子束轰击下,回喷靶材的轴向速度大于2.9mm/μs,而模拟结果表明理想情况下回喷靶材自由面的轴向速度可达9.7mm/μs。
Extraterrestrial impact events can produce an impact stratigraphical sequence consisting of impact melt-sheet in crater, proximal ejecta-blanket and tsunami nearby crater, and distal ejecta layer in distal sites. 地质历史中的地外物体撞击地球事件可在撞击点、近源区和远源区分别形成撞击坑熔融岩体、近源溅射岩席及海啸沉积和远源溅射层等一系列撞击地层层序。
Based on the cluster multiple labeling technique, a novel cluster detection algorithm is presented as an analysis subroutine in two-and three-dimensional molecular dynamic simulations of ejecta that take place as a planar shock wave encounters a free metal surface. 在团簇多重标号技术基础上,提出了团簇探测的新算法,并以此作为大尺度二维和三维分子动力学模拟冲击加载金属材料微喷射粒子团簇分析的子程序。
In the research of recent eruption history of the Tianchi volcano, a set of recent ejecta were recognized through field investigation, grain size analysis and petrochemistry analysis. 在开展长白山天池火山近代喷发历史的研究中,通过野外考察、粒度分析、岩石化学研究,识别出了一套新的火山喷发物。
The study of thermal activity and volcanic ejecta in terms of thermal radiation data and the combination of remote sensing and other techniques is presented. 使用热辐射数据以及将遥感与其它技术相结合能够研究火山区的热活动和火山喷发物。
Magnetic reconnection is involved in formation and ejection of coronal mass ejecta and plays a role in coronal heating and facilitates the entry of solar wind plasma and electromagnetic energy into magnetosphere. 磁场重联被认为是日冕物质形成和抛射的一种重要机制,在日冕加热和太阳风等离子体能量向磁层的输入过程中起着重要的作用。
Meanwhile, the ejecta model is one of sub-models of space debris evolution model and environmental engineering model. 同时,溅射物模型也是空间碎片环境工程模型与演化模型的子模型之一。
