After getting these four line-of-sight vectors, we inverse these data in special observation coordinate based on space analytical geometry, then we can get the vector that has three components on every coordinate, this vector will be treated as the total wind profile in the three-dimensional observation field, the result of this four-point method can basically reflect all the spatial and temporal variation of the atmospheric wind.

在得到视线方向风速矢量后，从选定的三维观测坐标系对这四个矢量进行空间解析几何的运算，可得到观测坐标系的各坐标轴上四个测量矢量的各坐标分量的标量和。从而以这个在三个坐标轴上都有分量的矢量作为在观测视场内的总的风场的风速矢量。

Through the study, we can conclude that improper slave function shows fairly good earthquake-reflecting capacity to earthquakes with MS 5.0 in eastern China, which can be regarded as comprehensive parameter to the medium-term and short-term earthquake prediction and can determine three elements of an earthquake more exactly.

利用模糊数学中异常从属函数方法对1990～1997年华东地区16种前兆观测方法，近5万组观测数据的综合前兆场进行了时空演化特征研究结果表明，异常从属函数μ对发生在华东地区的MS≥5.0地震有较好的映震能力，可作为中期、中短期预报的综合指标，对地震三要素可作出较为准确的判定

Heat may be measured in terms of any unit that can be used to measure energy, such as the joule or the kilowatt-hour.

一颗卫星可至少每天一次扫视地球很大的一部分，因此可对其它方法无法观测到的地区进行观测。

The relationship between barotropic tidal currents and sea level were established for the first 45-day period using the transfer functions and harmonic analysis, and then carry the prediction for the second 45-day period. There is very good agreement between the observed and predicted semidiurnal tidal current, the rms error is less than 3 cm s-1. However, prediction on diurnal tidal current is rather disappointing, the rms error is about 19 cm s-1, suggesting strong baroclinic tidal component may have a significant contribution to the tidal current, which is not registered in the sea level records.

利用转换函数与调和分析两种方法，验证水位预报正压潮流的可行性，将观测资料分为等长的两段时期，藉由第一段时期约45天的正压潮流与水位的关系，预报下一段时期约45天的正压潮流，结果显示半日潮流的观测值与预报值大致符合，其均方根约在3公分/秒以下；但是全日潮流的观测值与预报值的差异大，其均方根最大可达到约19公分/秒，推测其原因为斜压潮分量大而影响潮流，但是不会对水位资料造成影响。

Using Hwa-Lien and Wu-Feng-Shan radar data set respectively, the mean tangential wind component of Nock-Ten has been retrieved by original GBVTD method. It is found that the retrieved maximum mean tangential wind from HL is 14 m s-1 less than that solved by WFS data set. This large difference has been attributed to significant mean wind component perpendicular to the line connecting the radar and the typhoon center.

利用五分山和花莲雷达观测资料，分别透过GBVTD计算其轴对称切向风，结果显示，两座雷达计算之轴对称切向风最大值相差达14 m s-1，而这样的差异可归因於纳坦台风平均风垂直雷达观测分量较为显著所造成。

Based on the observation about the ramets characters of predominant clonal rhizome plants from wetland, their modular structure, reproductive allocation and population dynamics were measured and results indicate that:(1) There are 2 or 3 age classes of ramets and 3 types of tubers of Scirpus planiculmis population in terms of four times observation in three years.

对湿地优势根茎植物种群分株构件的年龄结构、构件性状、生殖分配及种群数量动态观测结果表明：(1)紧穗三棱草种群分株3年4次观测有2～3个龄级，球状根茎可划分为3个类型。

The method used in this paper can be applied in spatialization of other observed data and it is especially suitable when distribution of observation stations disperses.

该方法可供其它类型观测数据空间化、特别是在观测站点稀疏的情况下参考和借鉴。

The program compile with BASIC language and O'NILLs filter coefficient can be used for forward calculation with the gived model.with the input of the observed data and the assumeed model,one can obtain the observed curve and calcula- ted curve in the Same dual logarithm coordinate.
