It was shown that the stable carbon isotope composition of beef tissue was primarily dependent on the diet the animals were fed,meanwhile theδ~(13)C values of cattle tail hair, defatted muscle and crude fat all enhanced with the increment of the proportions of C4 constituents in diet, but those values were on the contrary with the enhancement of the proportions of C3 constituents. Moreover, allδ~(13)C values of different tissues were significantly correlated with the content of C4 and C3 plant material. So, the main component of cattle feed could be investigated with the help ofδ~(13)C values. Theδ~(15)N values of beef tissues were affected by feed composition to some extent, but it had no regularity. The cattle tail hair and defatted muscle enriched in 13C to their feeds gave different results between the two groups, but cattle tail hair enriched in 15N much more than defatted muscle and in the proportion of 3‰- 5‰, plus, cattle variety and individual had effect on the proportion of enrichment.

结果表明，牛组织中碳同位素组成主要受饲料的影响，牛尾毛、脱脂肌肉、粗脂肪中的δ~(13)C值随着C4植物含量在牛饲料中的比例增加而升高，随着C3植物含量在牛饲料中的比例增大而降低，并且均与C4、C3植物含量呈极显著的相关性(P.01)，用牛组织中的δ~(13)C值可以调查牛饲料中的主要成分；牛组织中的氮同位素一定程度上受饲料因素的影响，但未随饲料组成成分的改变而呈现规律性变化；牛尾毛、脱脂肌肉相对饲料对13C的富集比例两组试验结果不一致，牛尾毛对15N的富集比例大于脱脂肌肉，富集比例约在3‰- 5‰，饲料种类、牛个体等因素对富集比例均有一定影响；牛尾毛、脱脂肌肉、粗脂肪中的δ~(13)C值三者之间相关性达到极显著水平(P.01)。

本文认为中国地区间的经济增长，不仅存在着显著的"俱乐部收敛"特征，即按东中西划分的区域内部人均产出具有明显的聚集现象；而且存在着条件收敛的特征，即在具有相同的人力资本、市场开放度等结构特征的经济地区间存在着一定的增长收敛趋势。本文实证分析的结果还显示，各地区间工业化水平的差异和产业结构的变动对增长收敛性构成显著的影响。

The authors choose the proper regress methodology ac- cording to the characteristics of our panel data.

在根据面板数据本身的特征选择适宜回归技术的基础上，通过研究发现，在通过家族控股上市而形成的民营上市公司中，年度内董事会会议次数对企业的市场价值有显著的正向影响，而在通过兼并重组取得控股地位的民营上市公司中，这种影响并不显著；在考虑控股股东现金流权与投票权分离程度的调节作用后发现，随着控股股东现金流权与投票权分离程度的提高，年度内董事会召开会议次数的增加有利于企业市场价值的增加。

We find strong evidence that the turnover of provincial leaders largely hinges on provincial economic performance relative to their immediate predecessor.

我们发现如下现象：(1)经济绩效对这些省级官员的晋升有正的影响，其中任内平均经济绩效的影响较当年绩效的影响更大，更为显著；(2)在相对绩效考核中，在任官员相对于前任的经济绩效对其晋升有着显著的正影响，而他们相对于周边省份的绩效对升迁的影响则相对有限；(3)经济绩效对升迁的影响随时间不存在明显的变化趋势。

objective to study the intensity of magnetic field on a special meridian magnetic applicaˉtion.methods a special meridian magnetic application is found the variations of the intensity of magnetic field when it is in vitro,nipped by fingers and stuck on skin of meridian and non-meridian.results the variation of the inˉtensity of magnetic field and the difference of the two poles have a statistical significance when the special meridian magnetic applicationon straight line and interval10mm compares to on other conditions above.conclusion owing to a definite directivity of the magnetic field gradient is produced when the magnetic application on the meridians,it is hopeful to carry out the effects of the tonic and vent by acupuncture.

目的 研究循经传感磁疗贴的磁场强度变化。方法一种特制的磁疗贴，在体外、指捏、敷贴于皮肤表面的经络走行和非经络走行区时所测得的磁场强度变化。结果当该磁疗贴直线排列，间隔10mm时，与单独磁疗贴的初始相比，磁场强度发生明显变化，且具有两极差异；敷贴于皮肤经络走行区，与体外及非经络走行区相比，磁场强度变化显著，尤其在手阴经的走行区域，具有显著的统计学意义。结论该磁疗贴在经络走行线上形成的磁场梯度，具有明确的方向性，有望实现针刺产生的补与泄的作用。

It is shown from the study results that (1) SSC has obvious neap-spring and seasonal variations with periods being 14.7 days and 368 days, respectively, on an average, SSC during the spring tide was 2.96 times as much as that during the neap tide, and SSC in winter was twice as much as that in summer;(2) correlation coefficient between daily SSC and tidal range on the same day in a mean neap-spring period of 15 days was 0.86, and correlation coefficients between tidal range and daily SSC with one day and two day lag were 0.99 and 0.93, respectively, which indicates that the effect of tidal range variation on SSC has a one day or two day hysteresis;(3) the monthly mean SSC was negatively correlated with the monthly mean water discharge at the Changjiang River Datong station, especially well with the water discharge with a lag of 19 days.

悬沙浓度具有显著的大、小潮和季节性变化，变化周期分别为14.7 d和368 d，平均而言，大潮为小潮的2.96倍，冬季为夏季的2倍；2）平均大、小潮半月周期中日悬沙浓度与同日潮差之间的相关系数为0.86，与前1日潮差之间的相关系数为0.99，与前2日潮差之间的相关系数为0.93，反映潮差变化对悬沙浓度的影响有1~2d的滞后效应；3）月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤其与流量滞后19d的相关性最好。

The results of empirical research indicates that: Nonrecurring gains have a significant positive impact on the stock price, instead nonrecurring losses don't have a significant impact on the stock price; Nonrecurring gains and losses have an obvious information noise, and nonrecurring losses have greater information noise than nonrecurring gains; Nonrecurring gains and losses of the listed companies when the absolute value of more than 10% of the return of extraordinary items have greater information noises than the companies which has the absolute value of less than 10% of the return of extraordinary items.
