This investigation shows that exotropia was found more frequently in distance lateral phoria in myopes. Stereopsis acuity negatively correlated with the degree of my-opia and subjects with a lower stereopsis acuity had a higher degree of myopia. There was no significant correlation between distance lateral phoria and stereopsis acuity.

It is revealed in the study that the heavy metal concentration of Pb,Cu,Zn in the leaves of urban trees (Sabina chinesis,Platycladus orientalis,Euonymus japonicus,Platanus acerifolia, Prunus cerasifera) is significantly related with the relative heavy metal contents in atmospheres of different urban regions of Yantai city, while no such relationship is found in heavy metal Cd, and that the heavy metal amounts of Pb,Cd,Cu,Zn in urban soils had no direct impacts on the heavy metal concentrations in leaves of urban trees.

通过对烟台市区不同大气污染区域绿化植物叶片中重金属Pb，Cd，Cu，Zn富积量和大气与土壤中相应重金属的含量研究分析发现，植物叶片中重金属Pb，Cu和Zn的富积量与大气中Pb，Cu和Zn的相对含量呈显著的正相关，而植物叶片中Cd的富积量与大气中重金属的相对含量相关不显著。

The results of the physiological and biochemical indexes in callus tissue of Poncirus trifoliata tested under calcium carbonate(CaCO3) stress indicated that except total iron content, the negative correlations among CaCO3 concentration and peroxidase activity, superoxide dismutase activity, catalase activity, active iron content, soluble protein content and callus growth were recorded.

提要测定碳酸钙(CaCO3)胁迫下枳壳愈伤组织的某些生理生化指标的结果表明：除全 Fe 含量外，CaCO3浓度与过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性、活性Fe含量、可溶性蛋白质含量、愈伤组织增重均呈显著或极显著负相关，与培养液pH值呈显著正相关；随着培养的进程， POD活性、活性Fe和可溶性蛋白质含量、愈伤组织增重呈降低趋势， SOD和CAT活性先升后降，含高浓度CaCO3的培养液 pH值仅在20日左右略有降低。

Compared to healthy controls, GTCS presented decreased gray matter volume in the bilateral thalamus, frontal lobe, insula and cerebellum regions. There were no regions showing significant increased gray matter volume. Correlation analysis revealed that bilateral thalamic, left medial frontal gyrus, left middle frontal gyrus and left precentral gyrus GMV had negative correlations with the frequecy of epilepsy.

通过GTCS患者组与正常对照组的比较，发现GTCS患者的双侧丘脑、双侧额叶、双侧岛叶、双侧小脑等区域的灰质体积有比较明显的减小，但没发现有意义的灰质体积增高的区域；患者双侧丘脑、左侧中央前回、左侧额内侧回、左侧额中回和其发病频率呈负相关，没有正相关的区域。

But compared with the preinjury level, the latencies of MEPwere little shorter in TMS group and longer in sham TMS group,theamplitudes of MEP were higher in TMS and sham TMS group except lowerin hindlimb of sham TMS group.

两组大鼠患侧MEP潜伏期与神经功能缺损评分呈显著正相关，波幅与神经功能缺损评分呈显著负相关(P＜0.01)。

There existed very significant negative correlations among the microenvironment air temperature,surface temperature and the content protopectin and Ca in different periods and times,and very significant positive correlations between the humidity and the content of protopectin and Ca.

Then the author analyzes empirically China's terms of trade from 1981,and the causes of the change in the net barter terms of trade by means of regression analysis ,which can be quantitied.we get the results that China's net barter terms of trade had a declining trend while its income terms and factorial terms of trade had been improved,and the net barter terms of trade positively correlates with actual tariff rate,exchange rate and negatively correlates with GDP,besides,the factors which can not be quantitied such as pure price fighting,inappropiate tariff sytem,foreign-invested enterprises's tranfer pricing and region trade agreement also lead to the above trend of China's net barter terms of trade,and the change in China's net barter terms of trade had a neglect impact on international trade benefit.

得出中国价格贸易条件总体上存在下降趋势，收入、要素条件呈现改善的趋势；实际关税率、汇率与价格贸易条件存在正相关关系，GDP指数与其负相关。出口企业恶性价格竞争、不合理的关税体制、外资企业的转移定价、区域贸易集团是造成中国价格贸易条件下降的非量化因素。此外，本文分析了1981-2004年价格贸易条件变动导致的中国国际贸易利益变化，发现价格贸易条件变动对中国国际贸易利益产生了一定的负面影响。最后，本文在分析中国价格贸易条件变动环境的基础上，认为中国工业化阶段不高、贸易限制性政策实施空间的减小、&合成谬误&现象及知识经济时代的到来会在一定时期内对价格贸易条件变动不利。
