The significance of the standard with meteorological conditions, such as wind, including the instantaneous velocity at an average speed, 2 minutes, 10 minutes on average speed, the general weather forecast PuFu wind is 2 minutes?

气象意义的风具有标准条件，比如风速时距，包括瞬时风速、2分钟平均风速、10分钟平均风速，请问一般天气预报中的蒲福风力等级是2分钟的吗？

The monthly reanalysis data set and the anal yzed precipitation data set are used to study the interannual variabili ty of Somali Jet and its influences on the interhemispheric water vapor t ransport and on the East Asian summer climate. It is indicated that SMJ plays a key role in the water vapor transport between the two hemispheres.

利用美国国家环境预报中心和美国国家大气科学研究中心再分析月平均气候资料以及Xie和Arkin分析的月平均降水资料（1968～199 8年），针对索马里低空急流的年际变化及其对东亚夏季降水的影响问题展开了分析研究。

The median time spent on the entilator was three days (interquartile range two to six days) among patients who did not deelop pneumonia, and 11 days (interquartile range six to 19 days) among patients who deeloped entilator-associated pneumonia.

没有发生肺炎的病人使用呼吸机的时间平均为3天（四分位距为2到6天），而发生呼吸机相关肺炎的病人呼吸机平均使用时间为11天（四分位距为6到19天）。

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。

2As for cement-soil of different dates or formula, it is shown by the results of testing that their macrophysics indices correlate closely with the structural indices. Moreover, the micro-structural change under the unconfined compression is revealed.

分析了不同龄期、不同配方下的水泥土样宏观力学指标与其微结构参数——平均结构因子' F 、各向异性系数 A 、平均形状因子' f 的紧密相关关系，同时揭示了水泥土芯样在无侧限抗压过程中强度破坏的内在微观机理。

This paper concerns submanifolds with constant mean curvature in Euclideanspaces or unit spheres.

本文考虑欧氏空间或单位球面中平均曲率为常数的子流形，主要考虑极小的，即平均曲率为零的子流形。

Results The infection rate in dogs decreased from 18.5% and 14.7% before implementation of the control measure to zero in 3-4 years in Hutubi and Wensu Counties respectively. Prevalence of hydatid disease in new born sheep was reduced by more than 85% in comparison to the same age sheep before the control program in both counties.

结果 经过连续3~4年实施"犬犬驱虫、月月投药"措施，呼图壁县和温宿县的家犬细粒棘球绦虫平均感染率分别从实施前的18.5%和14.7%降为0；两县新生绵羊的棘球蚴平均感染率比控制模式实施前降低了85%以上。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
