In Alma it states,"Yea, he had been strengthening the armies of the Nephites, and erecting small forts, or places of resort: throwing up banks of earth round about to enclose his armies…the Nephites were taught…never to raise the sword except it were against an enemy… they had cast up dirtround to shield them from the arrows…the chief captains of the Lamanites were astonished exceedingly, because of the wisdom of the Nephites in preparing their places of security…they knew not that Moroni had fortified, or had built forts of security in all the land roundabout …the Lamanites could not get into their forts of security…because of the highness of the bank which had been thrown up, and the depth of the ditch which had been dug round about…they began to dig down their banks of earth…that they might have an equalchance to fight…instead of filling up their ditches by pulling down banks of earth, they were filled up in a measure with their dead…And caused them to erect fortifications that they should commence laboring in digging a ditch round about the land…And he caused that they should build a breastwork of timbers upon the inner bank of the ditch: and they did cast up dirt out of the ditch against the breastwork of timbers".

在阿尔玛书说：『他加强了尼腓人的军队，建造了小型堡垒，或凭藉处所；在周围筑起了堤岸来拱卫他的军队……尼腓人已被教导……除非抵抗敌人，决不举起剑来……他们在周围堆上了污泥来防避拉曼人的箭……这时拉曼人的总队长们非常的吃惊，由於尼腓人在准备他们的安全处所上所表现的智慧……因为他们不知摩罗乃已在周围各地的每一个城巿建筑了防御工事，或防御堡垒……拉曼人除了经由入囗处外，无法进入他们的防御堡垒，因为那土岸已堆得很高，那周围的壕沟已掘得很深……他们就开始去掘他们的土岸，使他们也能得到一条通往他们军队的小路，使他们能有一个均等的作战机会……非但没有推倒土岸来垫没他们的壕沟，反而将他们死者和伤者的身体垫进了不少……并吩咐他们建筑防御工事……他吩咐他们在濠沟的内堤上建造一道木头的胸墙；他们从濠沟中挖出污泥来，靠著木头胸墙堆起来

The survey of similar Orbal oxidation ditch is focused on the velocity distribution of concentration ellipse shape and concentric circles shape represented in oxidation ditches, analyzes the rationality of its device allocation and the problems shown in velocity profile, proposes the improved treatment.

现场同类Orbal 氧化沟流场的实测研究了椭圆形和圆形两种Orbal 氧化沟的水力现象，分析其设备配置的合理性，针对流速分布中出现的问题进行分析并提出了改进的措施。

Caterpillar rock trencher will play an important role in practical pipeline laying process.

在管道施工建设中，对石方段的管沟开挖一直采用传统的爆破成沟的施工方法，而履带式岩石开沟机在管道敷设的实际应用中可以发挥重要作用。

The interdental distance between the mesial groove of the first molars and distal groove of the second molars was measured on the maxillary dental casts. The interdental distances at the end of experimental tooth movement and retention were calculated. The effectuality of retentive appliances was evaluated by comparing the tooth movement distances between the experimental side and control side.

在加力结束后和保持结束后即刻制取上颌石膏模型，测量所有模型的第一磨牙牙合面近中沟与第二磨牙牙合面远中沟的距离，计算加力结束后与保持结束后的距离，比较实验侧与对照侧的牙齿移动距离，评价保持装置的有效性。

The formation of gullies can significantly increase soil losses from agricultural lands and severely impact ecology and environment. Yet current soil-loss assessment programs are unable to address these erosional channels. Furthermore, domestic research in this field is in its beginning.

切沟的形成极大的增加了土壤流失总量并导致严重的生态环境问题，但在目前的土壤流失评价项目中很少包含切沟内容，国内在这方面则更是基本处于起步和资料积累阶段。

To put it simply, as is usually the life of the zipper, a similar emphasis on the dentate沟纹square, arc-shaped than the traditional 25% more space.

简单来说，就像通常生活中的拉链，强调类似齿状的方形沟纹，比传统的圆弧状还多出25%的空间。

In order to solve the problem of absenting rationality and system-on design method of level ditch of runoff harvesting, based on theory analysis, the systematic design methods and calculated formula were put forward.

为解决现行水平截流沟设计方法缺乏合理性和系统性的问题，从理论分析入手，给出坡地水平截流沟的系统设计方法和具体的计算公式。

Henges—circular banks of earth paralleled by an internal ditch—earth barrows and mounds, circular timber structures, monoliths, and circles and horseshoes of stone were all common throughout Neolithic Britain and parts of continental Europe.

内缘有沟的环状土丘、土坟与土冢、圆形木材结构、单独巨石以及排列成环状和马蹄形的石块，在新石器时代的英国及欧陆某些地区都很常见（严格来说，史前巨石柱群并不像它名字中的henge所暗示的、是内缘有沟的环状土丘，因为它土丘跟壕沟的位置是相反的）。在它演变过程的不同阶段，史前巨石柱群反映了许多这样的传统。

The author also analyzed the difference of soil moisture between furrow and ridge, inside and outside of film, wide and narrow furrow under water control condition, put forward the index of soil moisture for postponed irrigation of maize, expounded the influence of water control in later stage on products and soil moisture of monoculture Maize.

在控水条件下，分析了垄背与垄沟、膜内与膜外、宽沟与窄沟的土壤水分差异，提出了玉米推迟灌头水的土壤水分指标，并阐述了后期控水对单种玉米产量及土壤水分的影响。

To get properly oriented, view the MPEG movie ("cine" button, next to the sagittal image) of the entire dataset, and find the central sulcus by first locating the marginal sulcus in the medial parietal lobe.

要正确定位中央沟，可以观看全部数据的MPEG影像点击矢状面影像旁的&cine&），并首先确定位于顶叶中部的边缘沟的位置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
