Just the CTK content, the ABA content in its tiller node were most significantly related and most significantly negatively related to the tiller number of intervarietal hybrid respectively, but beside the CTK content, the ABA content in its tiller node were significantly related and significantly negatively related to the tiller number respectively, the IAA content were also most significantly related to the tiller number of interspecific hybrid, this may be the reason why the interspecific hybrid had a high fertile spike heterosis.

品种间杂种分蘖盛期分蘖节仅细胞分裂含量与分蘖数呈极显著的正相关，而脱落酸含量与其分蘖数呈极显著的负相关。而种间杂种分蘖盛期分蘖节中的细胞分裂素含量与其分蘖数显著正相关、脱落酸含量与其分蘖数呈显著负相关，另外其分蘖节中的生长素含量也与其分蘖数呈极显著正相关，IAA在种间杂种中的共同参与可能是种间杂种具有较强的分蘖成穗能力的原因。

Therewas a significant characteristic of the vertical distribution of soil enzyme activity,the relationship analysis indicated that there was a significant positive relationshipbetween the catalase activity and OM,and total N,and effective P、K,and ex-changible Mg,there was a negative relationship between the catalase activity andBase Situatiou percentage,and Total Contents of Base;the activity of the polyphe-nol oxidase was positively related with OM,and negatively related with total N andexchangible Ca clearly;The urease activity decreased with CPR increasing,and thechange of the former two kinds of soil enzyme actirity was not significantly withCPR increasing,It is possible to be related with maned disturbance frequently.

随着代次增加，有机质和交换性Ca下降明显；土壤的CEC和交换性酸分别下降了8.8—16.1%和6.8—18.5%，因此，其养分总量亦逐代降低，其中有机质下降幅度最大；土壤酶的活性具有明显的垂直分布特征，相关分析表明，过氧化氢酶活性与土壤OM、全N、有效P、K和交换性Mg有极显著的正相关，而与盐基总量、盐基饱和度呈明显的负相关。多酚氧化酶活性与OM呈显著负相关，与全N、交换性Ca有显著相关。脲酶活性则有随连栽代次增加而有下降趋势，前两种酶在代次之间变化不明显，可能与频繁的土壤干扰有关。

It is analyzed that the main reasons for negative metacentric height are seepers of cabin in the superstructure. According to the types of curves of statical stability, the righting methods are discussed. It is suggested that the stability should be restored first and then the warship balanced.

In alkali metasomatic rocks, potassium is in reverse correlation with gold; and sodium is in reverse correlation with uranium, it is very important to ore-formation of uranium and gold.

研究中还认识到，在碱交代作用形成的碱交代岩中，钾与金负相关，钠与铀负相关，这对铀、金成矿有着重要的意义。

Objective To compare the superiority of different collection methods for pharynx nasalis secretion by throat swab and nasal catheter.

目的 比较咽部分泌物咽拭子取材和负压吸引奔导管取材的优越性。方法采用咽拭子和负压吸引鼻导管两种方法取咽部分泌物，分别用GICA法、免疫荧光法检测30例急性呼吸道感染患者的咽部分泌物中的流感抗原。

When inspects the connection degree between the objective project and the ideal point or negative ideal point is inspected, the existence of an opposit set is fully considered. By introducing the connection vector distance, the relative similarity scale is calculated, which to some degree improves the the traditional TOPSIS method.

该方法将理想点与负理想点视为确定不确定系统中相互对立的集合，在考察目标方案与理想点或负理想点的联系度时，充分考虑了对立集合的存在；并通过引入联系向量距离的概念，计算相对贴近度，从而在一定程度上克服了传统TOPSIS法的不足。

Single factor analysis: The total score of SCL-90 was obviously correlated with age, gender, parents＇ educational level and expectation, and school atmosphere （P〉 0.01）. It was negatively correlated with positive rearing pattern （affectional warm, understanding）（P〉 0.01）, but positively correlated with negative rearing pattern （punishment, firm control, excessive interference, partialism or rejection, and denial）.
