Moving average method is one of time series forecasting method, if time series have no apparent tendency moving, using moving average method can accurately reflect actual situation.

移动平均法是一种时间序列预测法，当时间序列没有明显的趋势变动时，使用移动平均就能够准确地反映实际情况。

When performing a moving average, you average over a number of periods.

当你使用一个移动平均，你对一段时间的数据进行了平均。

If the daily stock does not change the law of average, the moving average line constitutes MA.

如果将每日股价不规律的变化平均化，就构成了移动平均线MA。

Among them, the gaseous hydrocarbon yield of coal samples equally increases by 34%, and that of mudstone samples equally increases also by 30% or more.

There exist strong negative correlation between crystal size and crystallinity of illite in altered mylonite of low strain and low water/rocks ratios, and positive correlation between crystal size and crystallinity of chlorite in altered untramylonite of high strain and high water/rocks ratios.

在岩石应变较弱、水／岩比较小的糜棱岩带，伊利石的平均结晶大小与结晶度成负相关，而在岩石应变较强、水／岩比较大的超糜棱岩带，绿泥石的平均结晶大小与结晶度成正相关。

With Mab 2A3, the first positive cells were detected at the limb bud stage of the embryos. Distinguishable positive haemocytes with a diameter of about 7μm appeared in embryonic-nauplius. At the following nauplius I stage, configuration of haemocytes became more integrated and clear. Their diameters were almost similar to those of haemocytes from adult shrimp. With Mab 1H11, the first positive granular haemocytes were identified at the stage of embryonic-nauplius which existed in clusters with positive punctate fluorescence of granules distributed around the periphery of granular haemocytes.

通过对包括囊胚期、原肠胚期、肢芽期、膜内无节幼体期和无节幼体Ⅰ期在内的中国对虾胚胎的间接免疫荧光检测，最早在肢芽期胚胎中检测到2A3阳性信号；在膜内无节幼体期，2A3阳性血细胞平均直径约7μm，聚集成簇；在无节幼体Ⅰ期，血细胞形态更加完整清晰，平均直径已与成体对虾血细胞相似。1H11阳性大颗粒细胞最早在膜内无节幼体期胚胎中出现，这些细胞同样成簇存在，在其细胞质外围可见点状荧光。

The result shows:(1) the value of R in situ is higher than 0.8, which is lower than that in lab;(2) the averaged value of relative error in spring tide is higher than that of in neap tide and the value is less than 15%.(3) the particle size is the main factor that influences the precision of OBS, while the biology, the color of particle and water, the air bubble in water have some effect on it.

主要结果有：(1)现场OBS标定R值比室内标定偏低，但也在0.8以上；(2)大潮平均相对误差值变化比小潮大，在悬沙浓度低于1.5kg/立方公尺条件下，大小潮悬沙浓度平均相对误差都在15%以下；(3)悬沙粒径大小是影响OBS观测精度的主要因素，生物、泥沙颜色、水色和水中气泡等因素也对观测结果产生一定影响。

On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

三年平均而言，冬季悬沙浓度为夏季的2.0倍，大潮悬沙浓度为小潮的2.8倍；(2)平均的大-小潮半月周期变化中日悬沙浓度与同日潮差之间的相关系数为0.86，(显著性水平0.01)，与提前1日潮差之间的相关系数为0.99(显著性水平0.01)，与提前2日潮差之间的相关系数为0.93(显著性水平0.01)，反映潮差变化对悬沙浓度的影响有1-2天的滞后效应；(3)芦潮港月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤以流量滞后19天的相关性最好。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
