The difference between the Malthusian pessimists and the cornucopian optimists," says Postel,"comes down to little more than an assumption about grain land productivity over the next several decades—specifically, whether yields will grow at closer to the 1 percent rate of the 1990s or the 2 percent rate of the previous four decades.

波斯特尔说：&在未来数十年內，持马尔萨斯人口论的悲观主义者和众多乐观主义者的争论焦点，不过是估测农田谷物的生产力而已。具体来说，谷物产量增长率是接近二十世纪九十年代的1%速率，还是接近过去四十年的2%速率？&

Because of inappropriate operation between oncoming straight and left-turn vehicles of signalized intersections of urban areas in Taiwan the department of traffic ever offered corrigible opinions involve in right of way, center of intersections adjudging hard and indirectly encouraged to accelerate left-turn vehicles. But all still lack quantification analysis. Therefore, this problem is worth studying.This study will aim at safe passage of oncoming straight and left-turn vehicles for at-grade signalized intersections. So, this study will be based on row's theory, theory of traffic conflicts, and take many factors into consideration, such as the width of the intersections, types of the intersections, center of the intersections, the size of the vehicles, the location of the vehicles, the radius of turn, paths of operation, the speed of the vehicles, the types of collisions, the angle of road, and also deduce formulas of coordinate of paths. The main method used in this research is the simulation of different situations. By the method, the analytic model of safe passage of oncoming straight and left-turn vehicles for at-grade signalized intersections will be established, and this study will also subsume critical speed of conflict and expected number of times of safe passage. Finally involved rules of safe passage will be proffered.

鉴於台湾都市地区路口对向直行左转车辆常遭受对向车辆不当驾驶行为干扰，因而道路交通主管机关曾针对路口对向直行左转相关道路交通法规可能产生之对向直行左转路权判断不易、路口中心处不易区分、间接鼓励路口转弯车加速左转等问题提出检讨之修正意见，唯整体考量仍缺少〝量化〞分析，系一值得研究之课题，因此，本研究将针对号志化平面路口对向直行左转车辆安全通行问题於法规层面上之特殊性，以交通冲突理论、路权理论为基础，并考量路口宽度、路口型式、路口中心处、车辆尺寸、转弯半径、运行轨迹、行驶速率、行车位置、最终碰撞型态、道路交角等因素，先行推导车辆行驶轨迹座标公式，再利用情境模拟分析法，进行号志化平面路口对向直行左转车辆安全通行分析，分析过程中则纳入冲突临界速率与安全通行期望次数理念，并根据路口对向左转车辆安全通行轨迹、速率集中分布范围之分析结果及相关理论，研拟号志化路口对向左转车辆安全通行轨迹、速率，及对向直行左转车辆路权判断原则，以供驾驶者路口直行左转安全通行之参考。

This text first from desert, desertification, concept appraised to desertification start with, explain the desertificated purpose and meaning further, desertification purpose lying in explaining why the land is desertificated, desertificated course and desertificated development degree and speed appraised, the fragility of the natural environment, and the reason that the land depredate.

先从荒漠、荒漠化、荒漠化评价的概念入手，阐述了荒漠化评价的目的意义，进而说明土地荒漠化的原因、荒漠化过程和荒漠化发展程度、速率，自然环境的脆弱性，以及土地退化的原因等。

Speed: the amplitude of the velocity (the length of the velocity vector) but without the direction that velocity has.

速率：速度的幅度，但是它不附带速度的方向，物理学角度讲它是一个标量。

The multidimensional measure, with quantitative and qualitative measures combined, may offset the void left by any singular unidimensional measure, either quantitative or qualitative in nature.

提出一个从组织创新的数量、速率、效果以及效率等方面综合评价创新能力的四维概念与度量模型，将传统的定量与定性指标结合在一起，突破了一维定量或定性测度的局限性。

Besides, the detection of a number of target navigation parameters can be estimated. The goal of this paper is to present a PCA electric field algorithm for calculating the target headings, size/velocity rate and port/starboard location in relation to the electric sensor axis. This PCA algorithm is based on the simultaneous analysis of the three components （longitudinal, athwartship and vertical） of the electric signature in order to compare the time evolution of their waveforms as a way to determine the target parameters.

此外，还可估算探测大量的目标航行参数：目的是提供一种主分量分析电场算法，以计算相对电场传感器轴线的目标航向、尺寸／速率、左右舷位置：此种PCA算法基于同时分析电场特性的3个分量，以便比较这些波形随时间的变化，作为确定目标参数的方法。
