The results showed that the influence of negative interactions among woody species in this subtropical plot was greater than other studied tropical plots. All the 52 examined woody species at the Fushan plot behaved as diversity repeller within a 50 m scale and did not show scale-dependent neutral behavior.

结果显示，种间竞争作用在亚热带的福山森林样区内的影响力比在热带样区更为显著，在50 m空间尺度下，所有检验的52种福山林木物种是多样性排斥者，并且其中性性质并不会因空间尺度不同而变化。

High precision format, unstructured dynamic mesh with a large displacement and multi-species gas flows were computationally expensive, the problem of resourceless and inefficient of single computer appeared. Parallel arithmetic based on PC-Cluster system for the oblique detonation wave flow and the muzzle flow include high speed projectile were discussed. The results proved that the rationality of parallel arithmetic provided a new method to simulate the complex chemical reaction flows. The present code represents a validated, efficient and versatile tool developed for the simulation of hypersonic multi-species chemical non-equilibrium flows.

高精度计算格式、化学反应源项的刚性和大位移的运动边界处理都给计算和存储带来了沉重的负担，单机资源不足和计算时间长的问题凸现，利用PC机和局域网资源建立分布存储式并行计算系统，并基于非结构动网格和分区算法开发了复杂化学反应流场数值模拟的并行计算程序，对高速飞行实验弹丸诱导的斜爆轰波流场和含有大位移动边界的膛口燃气射流场进行了并行模拟，有效地缩短了计算时间，扩展了计算规模，为复杂化学反应流数值模拟研究提供了新的手段。

My daughter asked in accordance with the doctor to check that the scar is too small, do not meet the requirements, it is necessary to us to review resow chest hospital may be to the side, the doctor said that the pay role resow large, the children reflected the adverse serious, but only under the provisions of CDC, as long as the species that are not allowed regardless of the success of another species of the second.

宝宝按照医生的嘱咐去检查了，说疤痕太小，不符合要求，要我们到胸科医院复查补种，可到了那边，医生说，补种的付作用大，孩子的不良反映严重，而且疾控中心才下的规定，只要种过，不管成功与否都不允许再种第二次。

Connected other characters, it was thought that the species which the reticulate type represents should be created coordinate classification with other species of the genus.

结合其它性状，认为网纹型所代表的两种植物应与本属中其它植物建立并列的分类单元。

It was suggested that much attention should be paid on woodland improvement and plant species selection, especially shrub species, before revegetation in similar areas.

退化人工林的防治重点应放在现有林的改良和造林植物种特别是灌木种的选择上。

The check list of the first cases of human parasitic diseases reported in China during 1871-2006 contained 128 species of parasitic pathogens,and among them 38 species were the newly revisional records.

对1871-2006年我国人体寄生虫病首例记录作了校订，128个病原虫种列表作了说明，其中38种为本文新订正的记录。

It manages and support the Rhododendron Species Botanical Garden for the display and cultivation of the species.

它管理和扶持杜鹃物种植物园展示和培育这一物种。

And, she said, the loss of one species can have a ripple effect on other species in the ecosystem.

并且，某种物种的灭绝会对生态系统中的其他物种带来连锁反应。
