This paper studies the electrode combination of 3D tunnel DC focused method. At first, the authors calculate and analyze the current distribution of two point power sources with the same electrical property, and indicate that as currents exclude each other, current density has a maximum at a certain depth along the perpendicular bisector of the two point power sources and the depth is directly proportional to the distance between them.

本文研究了三维坑道直流聚焦法电极组合，首先计算分析了两个同性点电源的电流分布规律，指出由于电流的相互排斥作用，电流密度在这两个点电源的中垂线下一定深度处产生最大值，这个深度与这两个点源之间的距离成正比。

The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

从自扩散系数、横向弛豫和质子距离等NMR测定参数推测，在浓度为0.26 mmol/L（318 K）的N，N′-双-α，ω-丙烷溴化铵(16-3-16)溶液中形成了近似球形的胶束，胶束表面的带正电荷的铵基极性头呈锯齿状排列以减弱分子间静电排斥力的影响。

In the summer of 1998, over two frantic weeks in July, I wrote an essay titled The Future of Online Learning .(Downes, 1998) At the time, I was working as a distance education and new media design specialist at Assiniboine Community College, and I wrote the essay to defend the work I was doing at the time.

在西元一九九八年夏天，七月的两个疯狂的星期里，我写下了一篇文章《在线学习的未来》（唐棣芬，1998）当时，我从事远程教育工作，是一名阿西尼博因社区大学的新媒体设计专家，我写这篇文章是为了捍卫我当时的工作。

When a capillary tube, in whose inner hole an optical fiber has been fixed and whose axial deviation amount between an outer peripheral surface of the capillary tube and a core center of an end surface of the optical fiber is 1.5 mum or less, is inserted into the insertion portion of the thin tube and the end surface of the optical fiber is fixed at a position at which a distance of the end surface to a focal point position of the partially spherical lens becomes -40 mum or less, emission light has an emission light bend of 0.2 DEG or less with respect to the center axis of the thin tube.

当将光纤固定在内孔且外周面与光纤的端面的纤芯中心的轴偏移量在1.5μm以内的毛细管插入细管的插入部，并且将光纤的端面固定于部分球面透镜的焦点位置±40μm以内的距离的位置上时，出射光曲率为出射光相对细管中心轴在0.2°以内。

From this test results, it is obtained that the maximum lateral displacement occurs at a depth of about 0.75L; land upheaval build up rapidly and reach the maximum when the pile tip arrive at depth of about 6 m; and the increment. of excess pore water pressure reaches the maximum when the pile tip arrive at the piezometer level; while the maximum excess pore pressure presents a hysteresis quality with radial distance.

由测试结果可知，最大的侧向位移发生在距地表0.75L附近，地面隆起从桩贯入开始迅速发展，并在桩压入到6m左右时达到最大值，测点处超静孔压增量的最大值发生在桩端到达该点所在水平面时，而超孔压的最大值沿径向有滞后性。

It was absolutely a cute apartment at an unbelievable cool location, with everything you need: fresh food with reasonable price at walking distance, yammi back-street Chinese fast-food restranut with friendly uncle-like owner, fatanstic bars with cold beer and, most of all, a beatiful beach with smily sun-shine. Nothing could be better.

它真是酷的不能再酷了：步行可以买到物美价廉的鱼菜；后街有香喷喷的中式速食，老板大叔很亲切；海边的酒吧供应爽劲的啤酒；最要命的就是迷人的阳光沙滩。

On the other side of the old man, at some distance from him, there lay with head thrown back the motionless figure of a young soldier with a waxen pallor on his snub-nosed and still freckled face, and eyes sunken under the lids. Rostov looked at the snub-nosed soldier and a shiver ran down his back.

老头子身旁的另一个人离得相当远，他头往后仰，一动不动地躺着，这是个年轻的士兵，翘起鼻子，苍白如蜡的脸上长满了雀斑，翻着白眼，罗斯托夫望了望这个翘鼻子的士兵，一阵寒凉掠过他的脊背。

The principle of the method is as follows: The method employs a transmission grating plate placed over a sample surface at a small distance h. According to diffraction theorym an incident light wave is divided into both reflected and transmitted diffraction waves at the grating plate.

该方法的原理如下：该方法采用了透射光栅放置在一个小的距离超过每小时板样品表面据衍射theorym事件光波分为既反映和传播的格板衍射波分歧。

But to go on; After I had thus secur'd one Part of my little living Stock, I went about the whole Island, searching for another private Place, to make such another Deposit; when wandring more to the West Point of the Island, than I had ever done yet, and looking out to Sea, I thought I saw a Boat upon the Sea, at a great Distance; I had found a Prospective Glass, or two, in one of the Seamen's Chests, which I sav'd out of our Ship; but I had it not about me, and this was so remote, that I could not tell what to make of it; though I look'd at it till my Eyes were not able to hold to look any longer; whether it was a Boat, or not, I do not know; but as I descended from the Hill, I could see no more of it, so I gave it over; only I resolv'd to go no more out without a Prospective Glass in my Pocket.

我一直凝望着，看得我眼睛都痛得看不下去了。当我从山上下来时，那船影似的东西已完全消失了，我也只好随它去了。不过，我由此下了决心，以后出门衣袋里一定要带一副望远镜。我走下山岗，来到小岛的尽头。这一带我以前从未来过。

Caesar had already arranged his winter quarters on the Danube, and had brought up his army to within five days' march of the advanced posts of the enemy; and the legions which he had ordered Saturninus to bring up, separated from the enemy by an almost equal distance, were on the point of effecting a junction with Caesar at a predetermined rendezvous within a few days, when all Pannonia, grown arrogant through the blessings of a long peace and now at the maturity of her power, suddenly took up arms, bringing Dalmatia and all the races of that region into her alliance.

凯撒已将多瑙河畔的冬营部署妥当，挥军进至据敌军最后的目标仅仅五日行程之地，而森提乌斯·萨土恩尼乌斯受命所率诸军团距敌军差不多也是同等距离，不日之内将与凯撒在一预先指定之地点会师。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
