We grew fifteen plant species with and without non-coevolved polyphagous locusts and cosmopolitan, polyphagous aphids.

现在，对15个植物物种（包括以前已经表现出生存范围快速扩展的6个物种及9个相关的本地种）的生长状况所做的一项研究表明，向北-西欧扩展其生存范围的外来植物物种与本地种相比，暴露于地面下敌人和地面上广谱草食动物的机会都要少一些。

The adipose derived stem cells of inbreds train of rat wereinduced to differentiate into schwann-like cells and the cells were injectedinto the acellular nerve allograff.The proliferation or adhersion of these cells on the graft were observed by inverted microscope or ScanningElectronic Microscope. Activity of cells were detected using MTT. 10mmnerve gap of inbreds train of rats in two group were bridged by tissue-engineered peripheral nerve or autogenous nerve, the effect wereappraised by naked eye, recovery rate of sciatic function index,nerve-electrophysiological, histology, Transmission ElectronMicroscopy and quantitative analysis of recovery rate of myelinated fiberpopulations,diameter of myelinated fiber and thickness of myelin sheat.

For different silvicultural measures, the mechanical properties of Pinus sylvestris plantations were measured and analyzed. The results showed that the effect of silvicultural measures on many mechanical properties of Pinus sylvestris Plantations were not significant..In order to increase the mechanical properties of wood, growth-promoting and then get the better structure building lumber and glued lamination board, the stands on south slope or at the down of slope, and with density of 1.5m×1.0m, properly thinning could be selected. Results of this study can provide a theoretical base and good guidance for oriented breeding of Pinus sylvestris plantations.

摘 要：对不同培育措施的人工林樟子松木材力学指标进行测试和分析，结果表明：不同的培育措施（初植密度、间伐强度、坡向、坡位）对樟子松人工林木材的绝大多数力学强度指标有显著的影响，可选择阳坡、坡下、1.5m×1.0m、轻度间伐林分进行定向培育，来提高木材力学强度性能，从而加快林木生长，培育高产、优质的结构、建筑用材及胶合板材林。

To compare the growth characteristics of non-hematopoietic adult stem cells derived from rat fetal blood and rat bone marrow in vitro, and to study the differentiation of these stem cells into neuron-like cells in vitro,the fetal blood of pregnant rats and bone marrow of adult rats were sterilely collected; mononuclear cells were isolated by using standard Ficoll-hypague techniques and then cultured in DMEM/LG containing 10% fetal bovine serum.

为了比较大鼠胎血和骨髓中非造血成体干细胞（non-hematopoietic adult stem cells，NASC）体外培养过程中的生长特性及体外诱导两者向神经元样细胞分化的异同，在无菌条件下采集孕大鼠的胎血和成年大鼠的骨髓，用Ficoll-hypague分离液分离出单个核细胞后，种植于含10%胎牛血清的DMEM/LG培养液内。收获的NASC传代培养，用流式细胞仪检测细胞的免疫表型。

Under the highway into the village, the road on both sides will gradually enrich the landscape, and look out the window or the green stretches of undulating hills, or stones scattered to slowly flowing stream, all for the growth of the city's Children are strange and wonderful, they will be the side of the road or pigsties and laugh, or to give the cattle cars and the amazing way street full of persimmon, jujube, apricot, large fruit hanging over the branches, making the vertical branches are heavy ground, the tree may be the same as children and we are tired and happy, busy and happy with.

下了高速公路，进入山村，路两边的风景也就渐渐丰富起来，望车窗外或是翠绿的小山延绵起伏，或是石块散落地深涧溪水缓缓流淌，这一切对于生长在城市的孩子是新奇而美妙的，他们或是会为路边的猪圈而大笑，或是为会给车辆让路的黄牛而惊异，路边满是柿树、枣树、杏树，硕大的果实挂满枝头，使得树枝都沉甸甸的垂向地面，也许树儿和我们一样累而快乐着、忙碌而幸福着。

The effects of earthworm on soil enzyme activities,microbiomass carbon,microbiomass nitrogen and the growth of apple tree were studied by pot experiment,using the orchard cinnamon soil,brown soil and fluvo-aquic soil and two-year old'Red Fuji' appleMalus domestica Borkh.

以果园褐土、潮土和棕壤以及2年生红富士苹果(Malus domestica Borkh。)幼树为试材，在盆栽条件下，通过向盆土埋放蚯蚓，研究蚯蚓对土壤酶、土壤微生物量碳和氮以及苹果根系和新梢生长的影响。

This suggests that shoot apex is most sensitive to water stress and the ~(14)C-photoassimile distribution likely shifts from above-ground to root, being benefit to maintaining root growth and tolerance to water stress.

这表明茎尖对水分胁迫非常敏感，同化物向茎尖的运输受到抑制，运积重心由地上部转到地下部，从而有利于保持根系在胁迫条件下的生长，提高植物的抗旱性。

The EDX and EPMA analyses on crosssections of anodic films demonstrate that the anodic films on both aluminum alloys contain Al, O and S elements, with evenly distribution across the films.

此外在5056铝合金上的氧化膜中发现存在均匀分布的Mg元素，由此可见在氧化膜的生长过程中，Mg离子同Al离子一样，也在电场的作用下向外迁移。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
