查询词典 larch

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。

The reasons why quarter-sawn board of Larch had smaller wet compressing shear strength than flat-sawn board of Larch for repeatedly boiling samples were as follows: first of all, antiswelling efficiency between springwood and summerwood of Larch was different; secondly, pits of Larch had great effect on this aspect.

造成桦木反复煮沸压缩剪切强度径切板的比弦切板的要大的主要原因是在弦切面木射线是被横断的，因此，在弦面上留下射线管胞的孔隙，在反复煮沸时这些孔隙成为了水分的通道，因而使桦木反复煮沸压缩剪切强度径切板的比弦切板的要大。

Not long ago, the wind with the greatest whole world casts Chinese larch capital to allege publicly, financial crisis makes the copartner loss of Chinese larch capital a few dollars, face the future that the loss of a huge sum and inaccuracy decide, warning of Chinese larch capital says: Does hot the Kingdom of Wei of postscript paper procuress ask Lv rafts merchant which lid of astounded of ?

Lanzhou University,Lanzhou,730000The difference between the spectral reflectance curves of healthy and diseased larch canopies is obvious.In this work,we chose the larch plantations as the study object.Firstly,we selected 14 larch canopy samples and measured their spectral reflectance and photosynthetic pigment contents.Then we selected 8 spectral parameters to set up a series of linear regression models.

以吉林省延边州敦化、和龙两市林场中健康的和遭受落叶松早落病侵害的人工落叶松林为调查对象，在对野外采集的14个落叶松冠层样本进行光谱测量及光合色素含量测量的基础上，选取8个对落叶松冠层光合色素含量变化反映敏感的光谱参数参与建立其光合色素含量的一元线性回归和多元逐步回归模型。

The main reason why quarter-sawn board of Larch had greater dry compressing shear strength than flat-sawn board of Larch in normal conditions was great difference between springwood and summerwood of Larch.

造成桦木径切板胶合强度试件的常态压缩剪切强度比弦切板的小的主要原因是由于桦木木材本身弦径向强度的差异，即桦木径向的顺纹抗剪强度比弦向的大。

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现，小径木落叶松的径壁具缘纹孔数目较多，且多具纹孔膜，小径木落叶松除在树脂道中含有树脂外，在一部分管胞胞腔内以及一些木射线细胞中也含有树脂，在产生缺陷的小径木落叶松锯材中，连续加热方式下锯材的开裂缺陷最为严重，波动2时次之，波动6时几乎没有开裂现象；小径木大青杨心材导管中的层状浸填体含量较多，且径壁具缘纹孔较为密集，管间纹孔呈互列方式，绝大多数纹孔具有纹孔膜，干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生，其中连续加热干燥试验锯材的皱缩现象最严重，波动2时次之，波动6时干燥试验锯材的皱缩缺陷最小。
