查询词典 tropical

Thus, for three tropical cyclones occurred on different regions, three sets of altimeter-derived data of the sea surface wind and wave are selected, their structural features and relations between the wind and the wave under the influence of the tropical cyclones are analyzed respectively, finally, the most frequent occurring relations between the sea surface wind and the wave of the tropical cyclone over the South China Sea and two hindcast methods for wind field of typhoon based on altimeter-derived wind speed are presented.

据此，选取了高度计获取的3个出现在不同海域的热带气旋影响下的海面风、浪资料，进一步分析各个气旋影响下的海面风、浪结构特征及其关系，并给出了南海海域气旋海况下最可能的海面风、浪关系以及基于高度计风速资料的两种台风风场后报方法。

As a native of Litchi chinensis, China is abundant in germplasm resources in the tropical and south sub-tropical zone. In Hainan province, Some big wild litchi trees and batches of wild litchi have been found in the tropical origenate forestry of Bawang, Wuzhi, Jianfeng, Diaoluo, and Jingu Mountains. In addition, there are 4,000hm2 of litchi seedlings scattered on Hainan island. They comprise a huge gene pool of litchis germplasm resources,Which is both bases of seedling selection at present and source of genetic breeding in the future.

中国是荔枝的发源地，种质资源非常丰富，仅海南就有4，000hm~2荔枝实生树，此外，在坝王岭、五指山、尖峰岭、吊罗山和乐东金鼓岭上还有成片的野生荔枝，一起构成了一个巨大的海南荔枝种质资源库，既是我们目前进行实生选种的基础，又是将来杂交育种的源泉。

It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。

A tropical rain forest ; an ever-green forest that exists in tropical regions where precipitation is heavy all the year round ; there are vines , parasitic plants and overgrowth , as well as aerophyte besides those tall trees , bushes and herbaceous plants ; mainly distributed in the Amazon drainage basin in south America , the Congo basin , Malaysia , etc .

名 热带气候终年湿润地区的常绿森林群落。这些雨林区由于常年气候湿润多雨，除高大的乔木、灌木、草本植物外，还有繁茂的藤本植物、寄生植物、附生植物等。主要分布在南美亚马孙河流域、非洲刚果盆地及亚洲的马来群岛等地。例句去热带雨林里探险，必须扎上绑带。

Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。

As already mentioned, the first option will help conserve tropical forests and the cultures of numerous tropical-forest peoples, both Amerindian and caboclo.

正如我说过，第一个选择，将有助于保护热带雨林和文化的许多热带森林民族，无论是印第安人和卡巴克罗。
