落叶松的

As a result,the ray tracheid inner wall has sawtooth thickening obviously.The pit of cross field is windows and pine shape.The ratio of the tracheid length to width is about 50.Airdry density is about 598kg/m3.The shrinkage of difference is about 1.8;1%NaOH extraction and cell...

结果表明：紫杉木材射线管胞内壁锯齿状加厚明显，交叉场纹孔多为窗格状，偶尔为松型；管胞的长宽比平均值约为50，气干密度平均为598kg／m3，差异干缩约为1.8；1％NaOH抽出物、乙醚抽出物、纤维素含量较落叶松高，木素含量比落叶松低，其它化学指标与落叶松相近。

This study provides an effective and reliable method for identification of different larch species.

Prince Rupprecht larch will expand northeastward about 280 kilometers in 2050yr,and mo...

在未来气候条件下，长白落叶松和华北落叶松将可能替代目前占主导地位的兴安落叶松。

According to the transition probability matrix combining with stand original distribution, the change of stand structure in fifteen years was modeled.

根据转移概率参数和进界生长参数可以得到落叶松的转移概率矩阵，结合其初始分布可模拟15年后林分的结构变化。

In this paper, we analyzed the larch extract tannin, aminom ethylation of larch extract tannin, quaternization of cationic larch extract tannin and amphoteric larch extract tannin (sulfonation of the larch extract tannin quaternary ammonium) by infrared spectral analysis, confirmed the quarternization and sulfonate groups, and measured its water treatment properties such as flocculation, scale inhibition, results showed that quaternization of larch extract tannin and amphoteric larch extract tannin have better water treatment ability, can realize the multifunction.

本论文采用红外光谱法对落叶松单宁、胺甲基化落叶松单宁、阳离子落叶松单宁季胺盐、两性落叶松单宁进行了化学结构分析，并对其水处理剂性能如絮凝、阻垢进行了检测。实验结果表明：落叶松单宁季胺盐和两性落叶松单宁均具有较佳的水处理能力，是性能良好的一剂多效工业水处理剂。

But the basic results had inercommunity that both the precipitation of last summer and relative moistuer from September to October in last year, indicating that the increment of Larix leptolepis associated with precipitation and groud temperature of spring closely in the area.

创新点在于：本研究依据15株日本落叶松解析木资料及10项气象因子资料，采用逐步回归及关联度分析法较系统地探讨了影响豫西日本落叶松生长的气象因子，为日本落叶松引种、栽培及抚育管理提供重要依据。

They left it to wind through a slashy cut, leading the horses through brittle branchwood, Jack, the same eagle feather in his old hat, lifting his head in the heated noon to take the air scented with resinous lodgepole, the dry needle duff and hot rock, bitter juniper crushed beneath the horses' hooves.

他们就不走正道了，带着马穿树丛。杰克，头上戴着顶插着那片鹰羽的旧帽，仰头呼吸空气，空气中充满各种味道，灌木树脂的，干的落叶松的，烫的岩石的，还有马蹄下黏的踩碎的苦松针的。

Through investigation on relationship beween larch pure crop needle cast condition and forest soil in county Yitong of province Jilin, getting conclusion: pure crop needle cast condition growing on white betonies is more serious than growing on deeply brown soil.

通过对吉林省伊通县落叶松人工纯林落叶病病情与林地土壤关系调查发现：生长在白浆土类土壤上的落叶松纯林病情明显重于生长在暗棕壤土类土壤上的落叶松纯林。

If he had remained among the larches all night, he would have heard nothing of the stir at the Grange; unless, perhaps, he might catch the gallop of the messenger going to Gimmerton.

如果他整夜都待在落叶松的树林中，他就听不到田庄里的骚动；除非，也许他会听到送信人到吉默吞去的马蹄疾驰声。

Above all, on days such as this, when the blue eyes of Spring laughed from between rosy clouds, when the sunlight shimmered upon my table and made me long, long all but to madness, for the scent of the flowering earth, for the green of hillside larches, for the singing of the skylark above the downs.

当春天从玫瑰红的云彩中露出她的碧眼，当阳光在我的书桌上闪烁时，我渴望的发疯般地闻一闻那百花绽放的大地的芳香，看一看那山坡上落叶松的葱郁，听一听高地上云雀的歌唱。

The big eared hedgehog, the little owl, the sand gecko, the three-toed jerboa, and every show needs a villain - saw-scale - the viper!

大耳刺猬，小猫头鹰，沙壁虎，三趾跳鼠，每场戏都需要反派角色：蝰蛇。
