  size class
Tree species diversity of different layers reacted directly to the change of gap size class.
      
The gap size class with more seedlings did not correspond to size class containing more medium-size trees.
      
The biomass fractions of a given root size class compared to the total root biomass differed among plantation population types.
      
These results suggest that "fine roots", which are traditionally defined as an arbitrary diameter class (i.e., >amp;lt;2 mm in diameter) may be too large a size class when compared with the finest roots.
      
I investigated the influence of sampling method, habitat use, and size class on the sex ratio of Atlantic sand fiddler crabs in a Georgia, U.S.A., salt marsh.

Pollen grains of Wightia and related genera of Bignoniaceae and Scrophulariaceae were examined under LM and SEM with-an attempt to show how the genus Wightia correlates with the two families and therefore further determine its position systematically, and at the same time to clarify Chinese species within the genus Wightia,

本文通过光学显微镜和扫描电镜对岩梧桐属Wightia Wall.花粉进行了深入的观察,并与紫葳科和玄参科部分属种作了详尽的比较。结果认为,从花粉的大小等级、萌发孔特征、外壁内外层比例等看,岩梧桐属花粉与玄参科的花粉更类似,而与紫葳科的相距较大。孢粉学支持把岩梧桐属置于玄参科。该属的国产种,根据花粉的大小和外壁纹饰特征的差异划分为两个种较为合理和自然,不该合并为一个种。

Guotas are active elements for geoscience development. But nowdays the quotas of exploration survey units are in low level and have been run into difficulty. This article takes a detailed discussion around the four topics: 1. quarntee the fulfilment of output and economic effect quota substitute administration, and breaking up into several orders and allocating bonus. 2. equalitarianism or bonus share according to person' s position.

定额对促进地质工作起积极的作用,但当前地勘单位定额工作普遍存在水平偏低、执行困难的状况,本文拟就四个方面进行了论述:①以包代管,层层承包,层层节约分成提奖;②奖金按官职大小的“等级” 系数分配或平均主义;③“一线紧,二线松”,引起生产人员不满;④制定定额有两怕,既怕水平高了“鞭打好牛”,又怕低了职工多拿奖金。这些因素对今后地质工作定额的修改具有参考作用。

In an investigation of the effects of interference competition on size hierachy(sizeinequality)in spring wheat(Triticum aestivum L.)and oilseed rape(Brassica campestris),size inequality,esp.that of oilseed rape,appeared to increase with population density,theinequality in reproductive output estimated by dry mass of ears or siliques was greater thanthat in plant dry mass,the size inequality in vegetative growth periods was less striking thanthat in the maturing period,and the nearest neighbour distance(NND)of individuals wasrelated to their size.Such results support the interference competition model in which largeplants are able to usurp more resources and suppress the growth of their smallerneighbours.

本文报导了春小麦(Triticum destivum)和油菜(Brassica campestris)种群内个体间的干扰竞争对个体大小不等性的影响。结果表明,小麦和油菜种群的个体大小不等性随种群密度的加大而提高,油菜提高的趋势比小麦明显。植株生殖枝干重的大小不等性较生物干重大。植株营养期的大小不等性较成熟期为小。相邻植株的距离与个体大小有一定相关性。试验结果表明,个体间的干扰竞争是植物种群个体大小等级形成的重要因子。即种群内较大的个体抑制了较小个体的生长,从而加大了植株大小的相对差异和种群生物量集中于少数较大的个体的趋势。
