There was a positive correlation between each of them and MVD. VEGF expression was positively correlated with lymph node metastasis and C-erbB-2, negatively with ER, PR, PS2 status, thereas no statistical correlation between VEGF expression and age, tumor size, clinical stage.

实验还发现有淋巴结转移组VEGF mRNA水平明显高于无淋巴结转移组，有统计学显著差异（P.01），VEGF mRNA表达水平与ER、PR、Ps2表达呈负相关关系，三种方法测得VEGF表达水平均与C-erbB-2表达呈正相关关系，但却与肿瘤临床分期，患者年龄，肿瘤大小无关。

The result shows that: a positive correlation is found between the amount of application of chemical fertilizer and some factors, such as farming hours, attitude towards risks, total family incomes and the proportion of agricultural labour and non-agriculturallabour. A negative correlation is found between the amount of application of chemical fertilizer and other factors, such as farmers' educational background, their cognition of chemical fertilizer, and the channel of information. The agricultural incomes and planting areas seem to be not notable inflecting factors.

研究结果表明：户主的从农时间、风险态度、农户家庭总收入、以及劳力与非农比例情况对农户施肥量成正向相关关系；户主的教育程度、农户对于化肥的认知情况、信息渠道、施肥方式、是否施用有机肥、农户对于化肥利用率的认知以及农户对于污染认知程度等因素对农户施肥量成负向相关关系；农业收入和种植面积的影响则是不显著的。

In respect to board\'s structure: There exist positive correlation between firm value and setting directorate specialty committee;negative correlation between firm value and board scale,separation of the chairman and general manager;but an inverted U-shaped relationship between firm value and the ratio of family- director.

在董事会结构方面：董事会专业委员会设置与企业价值正相关；董事会规模、董事长与总经理两职分离与企业价值存在负相关关系；而家族成员董事比例与企业价值之间呈倒U型关系。

The results showed that except pods of main inflorescence, the other characters of the sterile and normal cytoplasms had not significant difference by t test. The correlation coefficients of length of main inflorescence, No. of first time branches and glucosinolates between sterile and normal cytoplasms was at 5 percent significant level, but correlation coefficients of the others was not significant. There were positive effects of male sterile cytoplasm on glucosinolates and weight of 1000 seeds, but different effects on the other characters when combinations were different.

结果表明：考察的12个主要性状中，除主序角果数不育胞质杂种F1和可育胞质杂种F1检验差异达5%显著水平外，其余11个性状2种胞质杂种F1上标 t检验差异不显著；主序有效长、第一次分枝数、硫苷等3个性状的可育胞质与不育胞质间线性相关关系显著，其余9个性状的线性相关关系不显著；NEA不育胞质对多数组合的硫苷和千粒重有优良相对效应，对其余性状的相对效应则组合不同正负效应不同。

结果表明，东海翼足类总丰度和出现频率有明显的季节变化，均为秋季最高，夏季次之，春季最低；总丰度在各个季节基本上呈东海南部高于北部、外海高于近海的分布趋势；春季的尖笔帽螺、夏季的锥笔帽螺、秋季的蝴蝶螺和冬季的马蹄螔螺是导致总丰度季节变化的最主要的种类；冬、春和夏3个季节丰度变化及4季总丰度的变化同表层或10 m层水温有非常显著的线性相关关系，与底层温度及盐度的相关关系不显著。

The prewashed samples and postwashed samples were analyzed by seminal fluid assay.RESULTS:(1) The positive rate of semen HBV DNA was 21.05%(12/57) with 4.7810~4copies/ml on average; the positive rate of serum HBV DNA was 81.82%(45/55 with 2.3310~7copies/ml on average. There is positive rank correlation between semen HBV DNA copies and serum HBV DNA copies;(2 There were 7 positive cases in 21 samples before washing, the 6 cases except one were positive after washing;(3) there arepositive rank correlation between viability、round cells、 abnormal morphology and semen HBV DNA copies.
