挖沟

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

We must dig a trench to drain away the water.

我们必须挖一条沟排水。

From nine to eleven he planned to dig a hole, or trench, and possibly find something good to eat buried in the dirt.

从九点到十一点，它打算挖个洞，或者挖条沟，这样做也许能找到点埋在土里的好东西吃。

From nine to eleven he planned to dig a hole, or trench , and possibly find something good to eat buried in the dirt.

而九点到十一点，它计划挖个坑，或挖条沟。或许能在泥土中发现什麼可以吃的东西。

We adopted many forestry techniques, including scarifying, weeding, draining, fertilizing, digging far-between dyke, choosing and breeding eximious clone. We also took measures of excavating aperture and irragating root, directly watering root, daubing remedy, stubbing died trees and sterilizing soil in the aperture.We carried through integrated preventional measures of chemical prevention and biological prevention, by using 200×CuSO4, 70% mancozeb 800×5% Chlorothalonil 800×, and Suillus grevillei. All of the meaures got favorable results. The preventional effect exceeded 72%. The incidence of disease descended from 15.5% in 1998 to 2.8% in 2002.This kind of disease was controlled on the whole.

自1998年开始，经过5年的系统研究，通过松土除草、排水施肥、挖隔离沟，选育优良无性系等林业技术措施；采用挖穴灌根法、直接浇根法、涂药法、死树挖除并对穴内土壤消毒等方法，使用硫酸铜200倍液、70％代森锰锌800倍液、5％百菌清800倍液和厚环乳牛肝菌进行化学防治和生物防治等综合防治技术，均取得了很好的效果，防治效果达72％以上，发病率由1998年的15.5％，下降到2002年的2.8％，使该病基本得到了控制。

Analyzed on dynamics and kinematics about rotary ditching machine , it is feasible and advanced on practice test.

通过对前置上切削旋转开沟机具运动学、动力学的分析和计算，以及对前置上切削旋转开沟功耗的分析，解决了小功率管理机挖深沟的问题；通过试验和生产考核，证明了该套机具可行性与先进性。

The ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.

对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究，结果表明：Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子（尤其是Ca2+），其雪层中的主要阳离子关系可在底部冰中得以较好的反映，但雪层中各离子浓度与海拔的相关性不明显，可能与海拔的跨度较小和挖取的雪坑较疏有关；雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。

They had built it to protect their ships, and had dug the trench all round it that it might safeguard both the ships and the rich spoils which they had taken, but they had not offered hecatombs to the gods.

达奈人的壕沟已不能阻挡特洛伊战勇的进攻，沟上的那道护墙亦然――为了保卫海船，他们筑起这堵护墙，并在外沿挖出一条深沟，却不曾对神祗供献丰盛的祀祭，祈求他们保护墙内迅捷的海船和成堆的战礼。

A boot-type jet trenching system is adopted which is towed by the supporting ship. It is mainly used for trenching hard sandy clay at the shoal area with water depth 0.8m to 30m. Diameter of the cable to be buried is up to 150mm, and the burying depth more than 2m. This system has advantages of simple structure, high burying speed and great trenching depth.

该系统采取滑靴型式的喷冲挖沟方式，理缆机由母船拖曳前进，主要用於水深在0.8~30m的滩海，底质为硬砂土和红胶泥层，埋设直径小於150mm的电缆，埋设深度大於等於2m。

Trough the analysis of stabilization safety on Tengzigou arch dam, some conclusions are obtained in the following:(1) Tengzigou arch dam is safe under normal poll level ;(2) stabilization safety factor of Tengzigou arch dam is about 4-5;(3) It is proved that combinatorial reinforcement measures are effective and feasible.

对藤子沟拱坝的数值计算和模型试验分析表明：(1)藤子沟水电站在正常蓄水位作用下，坝体和两岸坝肩是稳定的；(2)藤子沟拱坝的整体安全度大概为4～5左右；(3)东北院提出的对左岸泥岩层挖除处理并用混凝土置换的加固除险措施经研究表明该加固措施是有效、可行的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
