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。

Water originates mainly from the Soviet Union, Mongolia and China border Tannu Shan (friendship peak 4374 meters) in two small rivers, the water flows south and a small tributary of the Irtysh River, the lake has a narrow strait sedge, grasses swamps, surrounded by Europe, the extension of the Siberian taiga south, spruce, larch, Xinjiang, Xinjiang red cedar, fir, Pinus forest, etc. there is moss and Hagoromo grass, water, etc. Ranalisma. After the Xinjiang Uygur Autonomous Region in 1980 approved the establishment of nature reserves Hanasi (has been approved as a National Nature Reserve).

水源主要来自发源于苏联、蒙古和中国边界的唐努山（友谊峰4，374米）的二条小河、出水向南流入额尔齐斯河的一条小支流、湖的两岸有狭窄莎草、禾草沼泽、四周有欧洲、西伯利亚向南延伸的泰加林、云杉、新疆落叶松、新疆红杉、冷杉、五针松等林下有苔藓及羽衣草、水毛茛等。1980年经新疆维吾尔自治区批准成立哈纳斯自然保护区（已被批准为国家级自然保护区）。

The maximum rate of decomposition of soil organic carbon insubtropical wetness area is red soil under coniferous and broad-leaved mixed forest＞yellowsoil under grass＞yellow soil under shrub＞yellow soil under broad-leaved forest＞red soilunder camellia oleifera; decomposition rate of yellow soil is faster than red soil. Themaximum rate of decomposition of soil organic carbon in subtropical wetness zone isyellow-brown soil under mixed forest in Nanjing＞red soil under adult fir in Yujiang＞redsoil under broad-leaved forest in Yujiang.

湿润亚热带地区森林土壤有机碳分解速率最大值出现在培养初期的一周内，其顺序：针阔混交林红壤＞茅草黄壤＞灌木林黄壤＞常绿阔叶林黄壤＞油茶红壤，同一植被下黄壤有机碳分解速率大于红壤，南京混交林黄棕壤＞余江杉木(32年)红壤＞余江常绿阔叶林红壤。

Along the country roads, the escarpments of pines and fir s were black-green

沿着这郊区的道路，斜坡上的松树和枞树郁郁葱葱

The house itself was under the guardianship of the fir, the mountain ash, and the acacia; and a thick screen of them altogether

宅邸本身处在枞树、山梨树和阿拉伯橡胶树的荫蔽之下，它们一起构成一道厚密的屏障。

This dissertation mainly includes the following four aspects:(1) Design of oversampled near perfect reconstruction DFT modulated filter banks. Firstly,the property of transfer function and aliasing transfer function are analyzed.

首先，分析了传递函数和混叠传递函数的性质，给出了因果FIR DFT调制滤波器组的系统延迟与线性相位分析和综合原型滤波器阶数的关系。

To increase hardware utilization and minimize cost, we combine inter and intra prediction by a reprogrammable FIR filter, which is further implemented with systolic array.

利用在解码的过程中一个巨块不会同时利用到内部以及相互预测的特性，设计了一套既可以处理内部预测也可以处理相互预测单一硬体架构来增加硬体使用效率以及降低成本。

From the results, it was found that sufficient resorcinol was needed for PRTF copolymer resins to have cold-setting property. The PRTF copolymer resins made from Taiwan acacia bark extractives with P/=1/1 had cold-setting capability at the ratio of resorcinol to bark extractives was 25/75, but 50/50 was needed for China fir bark extractives to have cold-setting property.

由试验结果得知，PRTF-B共聚合树脂中仍须有足够的间苯二酚始可具备常温硬化性，以相思树树皮萃取物为原料者，在P/=1/1时，间苯二酚与树皮萃取物之比例为25/75者具常温硬化性，而以杉木树皮萃取物为原料者，则间苯二酚与树皮萃取物之比例则须50/50始具有常温硬化性。

The DSC analysis showed that the cold-setting process of PRTF copolymer resins was an exothermic reaction, and the heat flow appeared mainly at the initial stage after the hardener added, and then trended to relax. The PRTF-B7 copolymer resin made from China fir bark extractives had the exothermic peak more obvious than those made from Taiwan acacia bark extractives.

以DSC分析显示其硬化过程为一放热反应，且在硬化剂添加后之初期反应较为明显，随后即趋於平缓，以杉木树皮萃取物为原料之PRTF-B7共聚合树脂有较明显之放热峰。
