针叶树

For conifers which do not form an abscission layer at the base of the cone, shakers have been partially or completely unsuccessful.

对于球果基部不能形成脱离层的针叶树，摇树机的作用不大，或者完全不起作用。

In some conifers adventitious roots can form the largest part of the root system.

在一些针叶树不定根形成的根系统的最大部分。

It claims the world's only parasitic conifer and nearly two-thirds off the world's species of Araucaria trees, all of which are endemic.

它宣称是世界的唯一地方性的寄生针叶树和世界三分之二地方性的南洋杉树的种类。

Between these extremes lie the sal -dominated moist deciduous forest of eastern India; the teak -dominated dry deciduous forest of central and southern India; and the babul -dominated thorn forest of the central Deccan and western Gangetic plain.

在印度的上述热带雨林带和针叶树林带之间，印度东部以潮湿性落叶林带的婆罗双树为主，印度南部和中部则以干旱落叶林带的柚木树林为主，印度中部的德干高原和恒河平原则以热带旱生林带的阿拉伯相思树为主。

Major tree species found here include conifers, such as Korean pine, larch and Olga Bay larch, and coniferous-broadleaf trees such as white birch, oak, willow, elm and Northeast China ash.

主要树种这里找到包括针叶树，如红松，落叶松和奥尔加湾落叶松，和针叶树，阔叶树，如白桦，柞木，柳树，榆树和东北灰烬。

This text has made detailed exposition with macroscopic and the microscopic structural feature of the softwoods, emphatically in timber discern and nature classification, and in detail described some to represent the tree seed macroscopic and the microscopic characteristic, still shoot the timber to cut into slices through the optics microscope, in order to explain the main structural feature of the softwoods more ocularly.

本文就针叶树材的宏观与微观构造特征作了比较详细的阐述，着重于木材识别和性质分类上，并对一些代表树种的宏观与微观特征做了比较详细的描述，还借助光学显微镜拍摄木材切片，以便更加直观地说明针叶树材的主要构造特征。

The average percentage of tracheid volume is over 90% for softwoods species. Gas permeability of softwoods is in close relationship with the flow of gas through the tracheids.

针叶树材气体渗透性与气体在管胞中的流动特性和规律紧密相关，研究管胞的气体渗透流阻，可以获得关于针叶树材气体渗透性更深入的认识。

We have a lot of cone bearing plants around our school. Do you know what a cone bearing plant is?

我们学校附近种了很多的「针叶树」，你们知道什麼是「针叶树」吗？

One study found that conifers with the fungus are twice as likely to survive a drought as those without.

一个研究发现有有真菌的针叶树比没有真菌的针叶树有两倍可能在干旱中幸存。

The thorough knowledge of the gas permeability of softwoods can be gained by the flow-resistor of tracheids for the flow of gas.

本文从针叶树材管胞解剖结构出发，运用流体力学理论，导出了管胞 3个纹理方向渗透气体流阻的数学表达式，并由此计算了针叶树材管胞的气体渗透系数。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
