Coleophora obducta (Lepidoptera: Coleophoridae) is a defoliator of larch and exclusively latent in leaves. This article tested behavioral responses of C.

运用触角电位仪和&Y&型嗅觉仪测试鞘蛾对落叶松9种挥发物，即R-α-蒎烯、S-α-蒎烯、β-蒎烯、罗勒烯、水芹烯、3-蒈烯、月桂烯、莰烯和叶醇的EAG和行为反应。

The content of NH3-N of Coniferous mixed forest is higher than rainfall and other forest. The content of NH3-N of Corylus cornuta marsh is lowest. The purgative effect of NH3-N of Larix gmelinii plantation is better too.

樟落混交林的氨氮含量明显高于大气降水和其它林分类型，榛子灌丛的氨氮含量最低，落叶松人工林对氨氮的净化效果也很好。

Vertical zonation of plants, 700m here are pine, poplar, willow, pulling, etc. 8 kinds and a variety of economic trees. 1700m ~ 1000m between the growth of pine, birch, cypress, Lespedeza, etc., 1000m above with a small amount of Betula, Populus, weed, and six wood, Corylus, moss and so the distribution of irrigated grass, 1500m above the larch.

植物呈垂直分带，700m以下有油松、杨树、柳树、揪等8种及各种经济树种。1700m~1000m之间生长松、桦、柏、胡枝子等，1000m以上有少量桦、山杨、杂木林及六道木、毛榛、苔藓等灌草丛分布，1500m以上为落叶松。

Through the principal components analysis of 27softwoods,we found that the directionality of cell arrangements was accordant with theevolution order of Ginkgoaceae,Pinaceae,Taxodiaceae,Cupressaceae,the more evolutivewood species,the stronger directionality of cell arrangements along radial,but thedirectionality of cell arrangement along the radial of Larix spp.which was abrupt changedspecies was comparatively weak.

通过对27种针叶材的主成分分析，发现木材细胞排列方向性强弱基本符合银杏、松科、杉科、柏科的进化顺序，越是进化的树种木材径向排列的方向性就越强。另外，落叶松属等早晚材急变的木材径向排列比较弱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
