查询词典 cryptomeria

Sugi (Cryptomeria japonica D.Don) wood specimens were dried with radial restraint using superheated steam at up to 180°C, and the resulting restrained shrinkage stress was examined.

试验研究了日本柳杉在120-180℃高温高压过热蒸汽条件下，干燥过程中所伴随的收缩应力的发生发展特征，以及温度和相对湿度对径向收缩应力的影响。

The above ground biomassof black locust and cryptomeria stands takes a greater percentage of the totalbiomass than that of water fir and chinese fir stands.

在落叶期，水杉的林冠截留率明显较柳杉林小，而和刺槐林相近，但在盛叶期却明显较刺槐林高，而与柳杉林相近。

To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

Shanlinsi Forest Recreational Park is located more than 2000 meters above sea level. Looking over the forest, it is full of towering cedars and cypresses with a natural and primitive breath of air. In this vast forest area, there is a well-known pristine eco-forest and dead cryptomeria trees standing tall in the swamp. Such desolate beauty makes people feel really lonely.

海拔超过二千公尺的杉林溪，放眼过去尽是高耸的杉树、桧木林，有著自然而原始的气息，而在这片面积广大的森林中，有一片鲜为人知的原始生态林、一片因为九二一阻塞河道形成的沼泽地，一棵棵死亡的柳杉笔直的朝向蓝天，有种孤寂、苍凉的美感。

The similarity was the highest between Fraxinus velutina Torr and Morus alba, the second was Populus alba, and Cryptomeria Japonica was the last.

其中与桑树的同源性最高，其次是银白杨，最后是日本柳杉。

In this study, the influence of feedstock size (2×2×5 cm^3、2×2×10 cm^3、2×2×15 cm^3) on the fundamental physical and chemical properties of slow pyrolysis products, e. g. wood charcoals and vinegars were examined. The slow pyrolysis was conducted by using steel kiln at the heating rate of 100℃/hr, pyrolysis temperature of 700℃, and holding time of 1 hr and the feedstock were Cryptomeria japonica and Acacia confusa.

本研究系利用慢速热解法将国产柳杉与相思树依不同尺寸(2×2×5立方公分、2×2X×10立方公分、2×2×15立方公分)以固定床式机械窑，在升温速率100℃/hr下，将试料加热至700℃并持温1hr，探讨材料尺寸对热解产物木炭与木醋液基本性质之影响。

This paper analyzed the carbon isotopic ratios of tw o cryptoMeria, collecting froM West TianMu Mountain, Zhejiang, and studied th e t ree-ring carbon isotopic ratios evidence, for the atMospheric CO2 concentrati on change after Industrial Revolution.

植物在同化大气CO2过程中产生碳同位素分馏，因此，树轮中稳定碳同位素比值（1 3C/12C）不仅是重建古气候的工具，也是过去大气CO2浓度变化的敏感指示器。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
