枞树

Joey : Okay, and ah, this one here is a Douglas Fir, now it's a little more money, but you get a nicer smell.

好，这是一棵道格拉斯枞树，这个比较贵一点，但也比较香。

The mask is 75 feet tall and made of Douglas fir from WashingtonState.

桅杆75英尺高，由华盛顿州道格拉斯枞树制成。

Intended to evoke the grand lodges of the Pacific Northwest, the brick complex sits on 181 acres, framed by rolling hills, groves of Douglas fir trees, a meadow, and the McKenzie River.

太平洋西北的大旅馆，这个旅馆是由砖复杂的建成了一八一英亩的框架，由连绵的山丘，树林的道格拉斯枞树，一个草甸，和麦肯齐河构成的。

Out on the road the sunlight almost hurt, and he thought about the Cascades and fir trees and breezes along the Strait of San Juan de Fuca, near Kydaka Point.

外面公路上阳光炙人，他想的是喀斯喀特山脉和基达卡附近圣胡安。德。福卡海峡沿岸的枞树和清风。

The results of conversion show that the serious disc must be rejected because its reliable L-HCCF life is greatly less than an overhaul period. Finally, the load distribution of centrifugal and vibration force on labe is derived. Using two method, load on the crack labe gradually reducing and keeping constant with the crack propagation, a crack propagation analysis of fir-tree slot is carried out, and the calculating L-HCCF crack propagation life of slot on the unload method, which is nearly 3 times longer than that on constant method, is 20 times shorter than the pure low cycle life, and agree well with the experimental's.

最后，分析了离心力载荷和振动载荷在榫齿上的分布，进行了榫槽榫齿的有限元计算；提出了枞树型榫槽的卸载概念，并按带裂纹榫齿上的承载随裂纹增长而逐步减少和始终保持不变两种处理方法，进行了复合疲劳裂纹扩展及其寿命计算，由计算得出卸载下复合疲劳裂纹扩展寿命较单纯低周疲劳寿命下降二十多倍；按卸载处理的疲劳裂纹扩展寿命是按恒载处理的三倍多，前者与试验吻合，而后者则偏差较大。
