其心材

Its lumber material is narrow for the alburnum, distributes in north compared to the south narrowly, light yellow arrives the yellow light yellow, the heartwood to brown brings slightly red; Has the resin, the durability is bad; The lumber texture, the density, standard natures and so on the festival receive the geography condition influence which grows, is widespread as a result of this lumber distribution, but therefore the lumber material the variation is greatly more obvious than because of the condition other tree seeds; The lumber weight is ordinary, solid.

其木材材性为边材窄，分布在北部的比南部的更窄，浅黄到黄色，心材浅黄至褐色略带红色；有树脂，耐久性差；木材的纹理、密度、节子等格质均受生长的地理条件影响，由于该木材分布广泛，所以木材的材性因条件而变异大比其他树种明显；木材重量一般，较结实。

Tree of India and East Indies yielding a hard fragrant timber prized for cabinetwork and dark red heartwood used as a dyewood.

出产于印度和东印度群岛的一种树，其木材坚硬芳香，因其细木工艺而享有盛誉，其深红色的心材可用来作染料木。

To stuff with waste wool or cotton.tree of India and East Indies yielding a hard fragrant timber prized for cabinetwork and dark red heartwood used as a dyewood.

出产于印度和东印度群岛的一种树，其木材坚硬芳香，因其细木工艺而享有盛誉，其深红色的心材可用来作染料木。

The results showed that the proportion of aspirated pits in the respective earlywood and latewood of the air_dried sapwood was increased to 99% and 81%, while that of heartwood was also as high as 97% and 86% because most of the bordered pits were aspirated at its green state.

结果表明，边材和心材的生材经气干处理后，其中边材的早材和晚材纹孔闭塞率增加至 99%和81%，而心材因为其纹孔塞在立木时就已发生偏移，其早材和晚材纹孔闭塞率亦高，分别为 97%和 86

Stainless steel or casting iron is clad on the external for current brake disc to sustain wear and high temperature. The core material is high specific strength and lightweight, for instance, aluminum alloy, titanium alloy, etc.

其材料结构为3层以上的多层金属复合板，外侧皮材为现行之煞车碟盘高耐磨耗性材料，如：不袗、铸铁，内部心材为高比强度、轻量化之材料，如：铝合金、钛合金等。

Objective:To establish methods for identification of Dai medicine,the heartwoods and leaves of Cassia siamea.

傣药&埋习列&的心材与叶进行生药鉴定研究，为其深入研究与应用提供鉴定依据。

Contents of Cu, Zn, Ni, Cr and Pb increased steadily in tree-rings from the heart-wood to sap-wood at both sites, reflecting the increase in the bio-availability in the Delta area during the past decades. Peaks in Cu, Zn, Ni and most obviously Cr and Pb, were found in rings formed after 1990. It was suggested that the recent increase of the heavy metals in soil and atmosphere in the Delta was the main source contributed to the elevation of the heavy metals in the pine rings.

结果表明：西樵山马尾松林地表层土壤Cu、Zn、Cd和Pb含量均超过其在广东省表层土壤环境背景值，鼎湖山马尾松林地表层土壤除Cd外其余重金属含量在背景值范围内；鼎湖山和西樵山马尾松木质部中Cu、Zn、Cr和Pb含量均呈现从心材到边材上升的分布格局，反映了珠江三角洲环境中可供植物利用的重金属在过去有了增加。
