本文用化学方法制备的葡甘聚糖酯从结构上看具有表面活性剂的亲水亲油及聚合物两方面的特性，实验证明，在合适的取代度范围，当葡甘聚糖酯浓度在0.1%～0.01%时，其有较强的乳化力。

It thus became possible to study the cathode rays, and also the fluorescence they caused, outside the discharge tube and Lenard concluded from the experiments that he then did that the cathode rays were propagated through the air for distances of the order of a decimetre and that they travel in a vacuum for several metres without being weakened.

但是后来，1892年他在波恩大学做赫兹的助手时，赫兹让他观察了他的新发现，赫兹将一片盖上铝箔的含铀玻璃片放入放电管，当用阴极射线轰击铝箔时，铝箔下面发出了亮光。

The internalizing methods in America, Japan and European countries were introduced in the thesis, and the applicability of all the methods was analysed demonstratively. Three instruments adapted to Chinese situations were brought forward as follows:a Tax on the heavy polluted traffic modes; b Charge on the obviously unreasonable transport distances; c offer transport subsidies with the taxes and fares to the modes with low external cost.

文中重点介绍了美国、日本和欧洲国家运输业外部成本内部化的途径，并对各种措施在我国的适用性进行了实证性分析，提出以下三种适合我国国情的运输业外部成本内部化的方法以供参考：(1)对污染大的运输方式征收一定的税费；(2)对明显不合理的运输范围收取费用；(3)将征收的税费补贴给外部成本低的运输方式。

The property of the algorithms on linear problems is studied and the Broyden's methods have been proved that they are not descant. More precisely, the distances between the sequences obtained by solving the linear problems and the solutions of the linear problems do not decrease under any vector norm.

笔者研究了将该方法用于求解线性方程组时的内在性质，否定了一个自然的推测，指出它在解线性方程组时不是一个下降的算法，即所得到的点列与方程组的解之间的距离在任何向量范数意义下都不具有单调下降性。

It was designed to measure distances and determining location of objects.

它的目的是确定测量距离和位置的物体。

Although Arab mariners clearly plied the Maritime Silk Route, trading on a large scale over great distances,"this is the first Arab dhow discovered in Southeast Asian waters," says John Guy, senior curator of South and Southeast Asian Art at the Metropolitan Museum in New York,"and the richest and largest consignment of early ninth-century southern Chinese gold and ceramics ever discovered in a single hoard."

尽管无疑阿拉伯水手明显定期往返于海上丝绸之路，跨越非常远的距离进行大规模的贸易，纽约大都会博物馆南亚和东南亚艺术馆高级馆长约翰·盖伊说："这是在东南亚水域发现的第一艘阿拉伯独桅帆船，并且这是有史以来在一个单一场所发现的，9世纪早期南部中国最丰富、最大的货物发运。"

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
