D In determining if risk of collision exists the following considerations shall be among those taken into account: Such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change such risk may sometimes exist even when appreciable bearing change is evident, particularly when approaching a very large vessel or a when approaching a vessel at close range.

在断定是否存在碰撞危险时，考虑的因素中应包括下列各点：（1）如果来船的罗经方位没有明显的变化，则应认为存在这种危险；（2）即使有明显的方位变化，有时也可能存在这种危险，特别是在驶近一艘很大的船舶或拖带船组时，或是在近距离驶近他船时。

Prominence a wide variety of shapes and movement characteristics, in general can be divided into four categories:(1) quiet prominence, change is slow, longer life expectancy, up to the number, and with the presence of sunspots related to sunspots for a long time, it is also a little more;(2) the activities of prominence, from a quiet prominence changes years, the movement is faster, but lower than the sun's surface escape velocity, so mostly circular, the material eventually thrown off the plane back to Japan;(3) the outbreak of prominence, activities of the most intense one, and sometimes velocity can exceed the Sun the surface escape velocity, reaching 100 km D seconds, or even higher altitudes of up to one million kilometers, 20,000 kilometers thick;(4) crown-shaped prominence, looks like clouds, is a rather exceptional prominence.

日珥有各种各样的形状和运动特征，大体上可分为四类：（1）宁静日珥，变化缓慢，寿命较长，可达数目，并与黑子的存在有关，黑子多时，它也多一些；（2）活动日珥，由宁静日珥变化而来，运动速度较快，但低于太阳表面逃逸速度，因此多为环形，抛出的物质最终仍落回日面；（3）爆发日珥，活动最激烈的一种，有时运动速度可超过太阳表面逃逸速度，达100公里D秒，甚至更高，高度可达上百万公里，厚达2万公里；（4）冕形日珥，貌似浮云，是一种比较特殊的日珥。

With the implement of urbanization, there're thousands of small towns to construct. However, corresponding criterion still haven't come out ,such as water and drainage quota, which result in no standard to refer to, what's more, absenting systemic researches on variation rules and coefficients of total water and wastewater in towns. Therefore, the construction of many towns takes on luxury evidently.

随着城镇化战略的实施，目前我国有数以万计的小城镇亟待建设，但是，与小城镇建设相匹配的基础设施建设规范尚未出台，致使小城镇给排水工程建设过程中无标准可依，更缺乏小城镇用水量和排水量变化规律以及变化系数的系统研究，贪大求全、不讲科学地追求高标准的现象较为明显。

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.

我们并发现溅镀Fe之温度与瓦数，并不会对结构或是磁性质有显著的影响，Fe厚度的改变虽然也不会改变结构，但是对Cr/Pt/FePt/Fe磁性质却有明显的变化，当Fe厚度薄时(3、5 nm)，在Fe和FePt界面仅有弱的交换耦合力产生，Fe厚度是10 nm时，此时交换耦合力为最强，厚度再增加到15、20 nm时，Hc反而略为上升，同样的我们量测DCD曲线，也证实了Fe厚度10 nm的确有交换耦合力存在。

The major content of this thesis are as follows:1 Performed FEM analysis before strengthening, and to find out the reason for the cracking and present a strengthening scheme;2 Performed nonlinear FEM analysis before and after strengthening, and to get the varying rule of the relative displacement between the on-site cast concrete side wall and that between the precast concrete arch and the floor, as well as the stress distribution of the gallery;3 Performed on-site observation experiments on the 7~th gallery, and to get the varying rule of the relative displacement between the on-site cast concrete side wall, as well as that between the precast concrete arch and the floor.4 The results of the computation were compared with those of experiments, which verified the effect of the strengthening.

本文的主要工作有： 1 对加固之前的廊道结构进行有限元计算，找出廊道底板开裂的原因，提出加固方案； 2 对加固前后廊道结构进行非线性有限元计算，得到加固前后廊道两现浇边墙相对位移、拱顶与底板相对位移随水库水位变化的规律和廊道结构的应力分布情况； 3 进行廊道加固前后现场观测试验，得到廊道两现浇边墙相对位移以及拱顶与底板相对位移随水库水位变化的规律； 4 对比分析加固前后现场观测试验与非线性有限元计算所得结果，论证加固方案的合理性，验证加固效果。

进而按照我国林业的总体发展目标及建设布局要求，在人口增长、基础设施建设等因素的变化的背景下，考虑到区域经济增长与林地面积变化的关系，我们提出有针对性地林地保护、林业发展的决策建议。

The Yellow River Delta that is one of three most largest estuary delta in China locates an intersect area between the Economy Circle around the Bohai Sea and the Economy Belt of the Yellow River valley. Natural resources like petroleum, natural gas, bittern and terrestrial heat enrich the Yellow River Delta area. Moreover, the natural endow of wetland resources, marine products resources and land resources abound in this area.

黄河三角洲是我国三大河口三角洲之一，地处环渤海经济圈和黄河流域经济带的交汇点，有丰富的自然资源，如石油、天然气、盐卤、地热等，同时具有巨大的湿地资源、丰富的海产资源、广阔的土地资源，土地利用变化剧烈，成为研究土地利用变化的热点地区之一。
