The results showed that the rural residential land become fragmentized during the years 1995-2010. The indices of number of patches, area-weighted mean shape, mean fractal dimension of landscape structure in Suining county gradually increased. Interspersion and Juxtaposition index and Shannon's diversity index were decreased.

结果表明：1995~2010年徐州市睢宁县的农村居民点景观格局呈破碎化趋势，土地利用斑块数增加，斑块平均面积下降，面积加权平均形状指数上升，平均分维度小幅上升，散布与并列指数和香农多样性指数均在下降。

They use R/S analytic method to check up earnings yields, and find that both of earnings yields have long memory characteristic. It also performs short memory characteristic along with changes of sample"s initial time and interzone of time series. The average circular period of Shanghai"s stock market is 250 days, and Shenzhens is 400 days.

采用了R／S分析法对收益率进行检验，实验结果表明上证综指收益率和深证成指收益率都有长记忆特征，但随着样本初始时间和样本区间大小的不断改变，股市收益率在表现出长记忆性特征的同时，也表现出了短记忆性的特征；上证综指的平均循环周期为250天，深证成指的平均循环周期为400天。

The average thrusting duration was 20.9±0.5 seconds,and the average mating duration was 45.2±1.3 seconds.4 There was no copulatory lock during mating,and the male usually ejaculated following a single intromission after several thrusts.

平均抽动持续时间为20.9±0.5s，平均交配持续时间为45.2±1.3s.4东北虎在交配过程中无锁结现象，雄虎通常在一次爬跨多次抽动后即出现射精。

While 30-year mean temperature data from 624 meteorological stations in China was spatialized, the temperature was divided into regular component, which is affected by longitude, latitude and altitude, and irregular component affected by other local factors. They were spatialized with multiple variable regression and inverse distance weighted interpolation respectively. There was a correlation ratio of R=0.98 between temperature and geographical factors including longitude, latitude and altitude.

在对中国624个气象站多年平均气温数据空间化过程中，通过30秒分辨率的数字高程数据，把气温分解为受经纬度、海拔高度影响的规律性成分和受其它因素影响的非规律性成分两部分，并分别用多元回归和反距离权重内插方法对二者实施空间化，最后将空间化结果进行合成得到基於栅格的中国多年平均气温分布数据。

By performing an inverse Laplace transformation of the stretch exponential function a distribution curve of the diffusivity is obtained which is enables the molecular weight distribution to be extracted.The results show that the width of the molecular weight distribution increasing as the average molecular weight decreases during the degradation process.

结果发现，在降解过程中随着聚合物平均分子量的降低，体系中的分子量分布不断变宽，这一结果与GPC实验结果完全吻合，而且从PFG实验中得到的平均分子量变化趋势和随机断裂方式下的Monte Carlo模拟实验结果十分吻合，据此可以认为聚合物的降解是一个随机断裂的过程。

The concept of mean ionization potential of crystal is proposed, and the of Oxide Superconduetors is investigated in this paper.

本文提出了平均电离势的概念，并对氧化物超导体的平均电离势进行了研究。

By using the algebraic method, we obtain a new formula for the expected hitting time of random walks on strong-connected and aperiodic digrahs (irreducible and aperiodic Markov chain). From this formula, we obtain the explicit expressions for the expected hitting times of random walks on directed de Bruijn graph, directed Kautz graph and some graphs constructed from strong regular graph, etc.

利用代数方法给出了强连通非周期有向图上随机游动（即不可约非周期马尔可夫链）平均首达时间一个新的表达式，并利用这个表达式得到了有向de Bruijn图，有向Kautz图以及和强正则图相关的几类图上随机游动任意两点之间的平均首达时间。

Mean cold ischemia time was 17 ± 4 hours and mean warm ischemia time was 41 ± 17 minutes.

平均冷缺血时间为17 ± 4小时，平均热缺血时间41 ± 17分钟。

The average correlative coefficients of linear regression function for isochronous stress- axial strain curve are 3.92% higher than that of average correlative coefficients of linear regression function for isochronous stress- radial strain curve, so nonlinear creep property of the fine sandstone specimen in axial direction is correspondingly weaker than that in radial direction.

应力－轴向应变等时曲线线性回归函数的平均相关系数高出应力－径向应变等时曲线线性回归函数的平均相关系数3.92%，因此其轴向非线性蠕变特性相对于径向非线性蠕变特性更弱。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
