The correlation coefficient between 1 mol / l ntljoac extracted k and k uptake by corn plant was much lower than that with resin membrane k . 4 . the k adsorbed on resin membrane after extraction was easily desorbed by 0 . 5 mol / l hc1 solution . the k desorbed in the first time had a very significant correlation with k uptake by corn seedling in the - k treatment of pot experiment 用1mol l中性nh _ 4oac提取的土壤速效钾与盆栽耗钾试验中首茬玉米吸钾量之间的相关系数较低，虽然也达到了极显著水平，但明显低于树脂膜室内埋置法提取的土壤钾与玉米吸钾量之间的相关系数。
Upon using an artificial neural network ( ann ) a new short - term climate forecast model with the monthly mean rainfall in june in the north of guangxi as predictand is established making empirical orthogonal functions ( eof ) to the 36 predictors ( 15 ssa predictors , 21 500hpa height predictors ) with over 0 . 05 significant correlation level of previous 500hpa height and sea surface temperature ( sst ) field , and selecting the high relative principal components , at the same time , a new approach of constructing ann learning matrix is developed . predictive capability between the new model ( principal components ann model ) and linear regression model for the same predictors is discussed based on the independent samples and historical samples 本文通过对广西北部6月平均降水量(预报量)同北半球月平均500hpa高度场和北太平洋月平均海温场进行相关普查，选取了前期36个同预报量相关显著水平达到0 . 05以上的预报因子( 15个海温场预报因子， 21个高度场预报因子) ，并运用自然正交函数展开方法对这36个前期预报因子展开，取其中同预报量相关程度高的主成分，结合人工神经网络技术，提出了一种新的构造人工神经网络学习矩阵的方法，建立了一种新的短期气候预测模型。
In the hillslope , d ( ) , c ( ) and k ( ) of soil water have high spatial correlation . d ( ) , c ( ) and k ( ) are significant affected by soil water content , capillary pore and sand content bulk density and non - capillary pore aperture are significantly affected on permeability rate . correlation analysis indicates that it is significant correlate 在坡面上，含水量、毛管孔除和砂粒含量对土壤水的扩散率、比水容量和导水率的影响较大;容重和非毛管孔隙对渗透率的影响较大，相关性检验达显著和极显著水平。
At the same time , the results of analysis of molecular variation ( amova ) revealed that the variance of inter - populations and inter - groups affected the total variance of fenneropenaeus chinensis significantly . the analysis of genetic structure indicated that the coastal population of yellow sea and bohai sea was constituted of several populations that has differentiated , which proofed the hypothesis of kong jie . 2 群体分级分析结果也验证了shannon指数和nei指数的结果， amova分析表明：中国对虾总群体的遗传变异有78 . 81是由群体内个体间的遗传变异引起的，同时， amova分析表明中国对虾在组间和组内/群体间的变异对总变异的影响已达到了极显著水平。
To qinmai11 with high n efficiency , the order of contents of protein and protein components in grains among n form treatments was conh2 - n > nh4 ( superscript + ) - n > no3 ( superscript - ) - n , the difference in contents of protein , globulin and glutenin in grains among three different n form treaments was significant 高氮吸收型小麦品种秦麦11籽粒蛋白质及其组分含量均表现为酰胺态氮处理铵态氮处理硝态氮处理，处理间蛋白质含量、球蛋白含量、谷蛋白含量的差异达到显著水平。
( 3 ) the effect of enhanced uv - b radiation on productivity of maize the results show that the productivity of maize was decreased because of the photosynthesis of maize seedling , but the decrease was not prominent since the photosynthesis of grown - up plant was not affected ( 3 ) uv - b辐射对玉米产t的影响通过对增强uv - b辐射下玉米产t的检测分析表明，虽然uv -百辐射降低了玉米幼苗的光合作用，但因其成株的光合作用未受明显影响，因此玉米产t虽有所下降，但未达显著水平。
The lowest species diversity occurs in the community iv in which microlepia sino - strigosa ching is the dominant species , while the highest species diversity occurs in the community i . in the communities studied , the total related differences vr are from 7 . 19 to 4 . 95 , and the test statistics w are from 229 . 96 to 49 . 95 , which indicates a notable positive correlation among species which have consanguineous relationships each other in the communities and the communities are in a fairy stable period . from the test of the interspecific relatedness among species in the communities we know that s . tsinyunensis present negative correlations with all the concomitance species , among which there are 8 species pairs of notably negative correlation and 51 species pairs of extremely notable negative correlation 4 )群落主要物种间联结性检验中，对各个群落调查的物种和种对依次为(从群落) ： 20种44对、 11种38对、 16种42对、 13种16对、 11种26对、 14种51对、 14种20对、 17种51对，其中缙云黄芩与群落中其主要伴生物种间全部表现为负联结，其中有9个种对间联结性达到显著水平，有50个种对间联结性达到极显著水平。
Third , the results indicated that global social support is negatively related to both work - to - family conflict and family - to - work conflict . objective support is negatively related to family - to - work conflict . coefficient of correlation between subjective support and work - to - family conflict was n ' t significant , and so are both subjective support and family - to - work conflict 第三、总的社会支持与工作家庭冲突和家庭工作冲突之间均呈显著负相关；客观支持与家庭工作冲突之间达到显著的负相关；主观支持与两者的相关则均未达到显著性水平；对支持的利用度与工作家庭冲突的负相关达到极显著水平。
In the end , cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as metoorological covariates could more validly evaluate efficiency of cloud seeding operations and significant level of ca - fcm method was higher than the other methods , because it adopted cluster analysis which highly improved the correlativity between rainfall distributions in the control area and target area , and used grid interpolation which enhanced exactness of calculating precipitation rainfall , and chose atmospheric precipitable water as the covariant which increased the inferential accuracy of natural rainfall on the cloud seeding operational area 最后，得到以降水量和整层大气可降水量为协变量的ca - fcm方法，由于采用聚类分析( ca )方法，提高了对比区和影响区相关性；采用网格插值技术提高了雨量的计算准确度；引入了不受催化影响的物理协变量(整层大气可降水量) ，提高了作业区自然降水量估计值的准确性；所以评估效果最好，显著水平高于0 . 05 。
Quality besides micronaire value and elongation of relevance not significant , other quality traits of both showed significant level ; yield and quality traits associated single boll weight and the first half of the average length uniformity index significantly related , and the breaking strength of correlation was significant , and micronaire value was negatively correlated ; lint and micronaire value elongation reached significant levels and a very significant level , and on average half the length uniformity index , breaking strength of correlation was significant but was negatively correlated 品质性状间除了麦克隆值与伸长率的相关性不显著之外，其余品质性状间均呈现出极显著水平；产量性状与品质性状的相关性中单铃重与上半部平均长度、整齐度指数相关性显著，与断裂比强度相关性极显著，与麦克隆值呈负相关；衣分与麦克隆值、伸长率分别达到显著水平和极显著水平，与上半部平均长度、整齐度指数、断裂比强度等相关性极显著但呈负相关。
