With longger fruit and more key fruits,moreover, the two traits showed significantly positive correlation (r=0.888). Of the 11 floral and fruit quantitative traits, the length and width of perianth segment and 6 other traits were different significantly among the three groups,which were successfully used in group-discrimination by means of the method of principal component analysis.

在所研究的11 个花果数量性状中，花被片长度和宽度等10 个性状在三大类群间差异极显著，主成分分析结果表明第1 主成分(贡献率69.11%)综合了各性状的主要信息，依据第1 主成分可以对三大类群进行区分，其中北美鹅掌楸类群第1 主成分值最大(变幅0.7156～1.3916，平均1.0408)，杂交鹅掌楸类群(变幅-0.0865～0.3959，平均0.2646)居于两个亲本类群之间，鹅掌楸类群(变幅-1.5443～-0.8855，平均-1.2426)最小。

Finally,as an application of the theorem,a new minimax inequality is given in general topological spaces.

最后，应用此非空交定理，在没有凸结构的一般拓扑空间中得到了一个新的极大极小不等式。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。

Pollcn morphology of 11 Heracleum species was examined under LM andSEM. It is shown that pollens of these specics are all of retangular type andequatorial constricted type, with polar views of 3-splitted round, obtuse triangle ortrianglc. Interspecific variations exhibit in pollen size and exine exolamelle.

对独活属11种植物的花粉进行光镜和扫描电镜观察发现，本属花粉为伞形科中比较进化的矩形型和赤道收缩型；极面观3裂圆形、钝三角形、三角形；花粉大小及外壁纹饰在种间存在明显差异。

Surprisingly, we found that a very short period of exposure to ovalbumin was sufficient to elicit early changes of remodeling.

令人惊讶的是，我们发现暴露于卵白蛋白极短时间足够显示重构的早期改变。

The carboxylation efficiency on May of 1 and 2 year needle of slash pine's half-sib was the lowest while the carboxylation efficiency on August to September of 1 and 2 year needle of slash pine's half-sib was the highest.

使用LI-6400便携式光合测定系统，研究了湿地松优良半同胞家系的光和CO2响应情况，结果表明：不同湿地松半同胞家系光响应曲线、CO2响应曲线的特征参数在家系品种间有极显著差异。

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.
