There are many kind of platinoid minerals in the Cu-Ni-Pt deposit of basite and ultrabasite rock in the area of Danba, Sichuan, such as:(1) telluride, tellurbismuth and tellurantimony,(2) antimonide,(3) arsenide,(4) native element.

四川丹巴地区基性、超基性岩型Cu-Ni-Pt族元素矿床中，含有多种Pt族元素矿物，主要有：(1)碲化物及碲铋化物、碲锑化物类，(2)锑化物类，(3)砷化物类，(4)自然元素类。

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。

With the fast development of the world trade and the technology of navigation, a vessel is becoming larger in size, higher in speed, more specialized in use and automatic in manoeuver; the seamen are much more multinational, and some sea areas are undergoing a heavier transportation pressure. All of these make the navigation environment worse and svessels manipulating ability lower, especially in those narrow channels.

但是，随着现代世界贸易和航海技术的飞速发展，船舶向大型化、高速化、专用化、自动化发展，船上配员向多国籍化发展，局部地区交通运输日益繁忙，尤其是在狭水道操纵安全，使得船舶航行环境变的恶劣和船舶运动性能也有所降低。

Cloudina was known as the first animal acquired mineralized skeleton at the terminal Neoproterozoic,but it was not the only exception that could secret minerals. More evidence of diverse skeletal animals came from deposits before the Cambrian"big bang". A relatively diverse tubular microfossil assemblage is described from the Terminal Neoproterozoic Dengying Formation of South Shaanxi, China.

末元古纪以Cloudina为代表的管状动物化石是目前世界上公认最早的具矿化骨骼的生物类群，在世界许多地区都有发现，但它并不是当时唯一的矿化生物类型，更多的动物骨骼化化石证据在寒武纪大爆发之前的沉积物中时有发现。

Based on palynological data,we suggest that the retreat of the Tethys and Parat ethys from southern and Central Asia in Eocene and the uplift of Qinghai-Xizang Plateau in Miocene have largely shielded the monsoon climate northwestward,and have resulted in the Tertiary aridification in NW China.

文章依据孢粉资料讨论我国西北地区第三纪时期植被的演变情况，认为始新世时古地中海和副古地中海自南亚及中亚地区的撤退，以及中新世时青藏高原的隆起对东亚季风的屏蔽，都对西北地区的干旱化起了重大作用。

A great diversity of land cover types is present in urban areas. This diversity makes urban areas spatially and spectrally heterogeneous, and in turn makes urban environmental modeling challenging.

都市地区的土地覆盖物是多样的，这使得都市地区在空间上及光谱上非常的异质化，也使得都市地区的环境模式化非常困难。

In order to understand the influence of alien plant in Guanzhong region and pretect local agriculture,we would study the allelopathic effects and their risk assessment of Erigeron annuus,Amaranthus retroflexus and Eleusine indica for main crops.

为了解外来植物对本地区栽培作物的影响，保障农业生产的持续安全性，我们对一年蓬、反枝苋、牛筋草3种关中地区常见外来入侵植物对关中地区主要栽培作物的化感作用和危害风险进行了评价。

There are some grass seeds recommended for ecological restoration , for example, Kentucky bluegrass, ryegrass, coronilla, festuca arundinacea, sword-bamboo and euonymus fortunei.3Regarding JBA,YQS, and CXL fertilizer as addition agent of the ecological material, magnetic fertilizer as ecological fertilizer, the material take on character such as water holding capacity, fertilizer retaining, prime cluster structure and binding power, which realize the destination of ecological protection of the abrupt rock slope.4Ecological material protection slope techniques, which is suitable for abrupt rock slope in high-cold area, has been formed elementarily.

高寒地区生态护坡的草种应选用具有抗寒、抗贫瘠和适宜粗放管理的冷季型草种，推荐使用的川西高寒地区生态护坡植物种属为：草地早熟禾、黑麦草、小冠花、高羊茅的草种组合，剑竹灌木种，以及小叶扶芳藤藤蔓植物种。(3)适当配比的高分子材料JBA、YQS和生态肥料CXL作为生态基材的添加剂可使基材具有保水、保肥、优质团粒化和粘结性能，从而达到生态护坡的目的。(4)开发了JYC生态护坡基材，初步形成了一套适合川西高寒地区岩质陡边坡生态基材防护的技术方法体系。来源：Ac9BC论文网www.abclunwen.com

Vegetation fractions in different districts of Wuhan were calculated based on remote sensing images (TM images and ETM+ images) in 1988,1991,1996 and 2002 by employing method for dimidiate pixel model,and the vegetation fraction maps of different periods were generated to analysis the temporal change of vegetation fraction of Wuhan area.

利用1988、1991、1996和2002年4个时相的TM和ETM+遥感影像为数据源，以归一化植被指数像元二分法为植被覆盖度估算模型，计算了武汉地区不同时期的植被覆盖度，生成了该地区不同时序的植被覆盖度图，以此分析武汉地区植被覆盖度的时空变化。

Nowadays is an era of economization and information, more and more people would like to live in the place nearby waterhead and beautiful landscape. Zoology of this place is fragile, and easily invaded by disaster. When anti-disaster investment is implemented at this place, disaster fatalness is degraded, environmental quality is improved, more and more people move to this place, more and more enterprise invest over there, what all this will help to raise land-value and promote area flourish. This is the indirect effect caused by anti-disaster investment.

在当今经济化和信息化的时代，人们更希望居住在靠近水源、山川秀丽的地方，而这此地方往往生态脆弱、易受灾害侵袭，对这些地区进行防灾投资，可以使该地区受灾的危险性降低，环境质量得到改善，从而促使更多的家庭来本地落户、更多的企业来本地投资，促进了地价的上扬和地区的繁荣，这是防灾投资的间接效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
