These are monitoring, mapping, auditing, documentation and calculation. This technology may be applied to the monitoring of facilities and process systems, chemical storage mapping, the layout of fire-protection equipment and emergency escape routes, regular check listing of equipment and safety procedures, regulation and directive inquiries, measurement of fan performance and pipe balance designing.

行动监控的应用范围包括厂务及制程系统现有的所有监控工作，行动地图包括厂房化学品储存图、消防设施如消防栓灭火器防烟袋的分布位置图及紧急逃生路线图等，行动查核包括所有设备及安全措施的定期查核表单，行动文件则主要应用在法规标准及规定的查询，行动计算的内容主要是风机性能曲线及管路平衡设计的相关计算。

In this paper, taking nodal injection power and voltage operation curve of PV node as foundation, according to the basic property of numerical characteristics of random variables and relevant equations for probabilistic load flow calculation the expectations of nodal current, reactive power at PV node and power at balancing node as well as computing formula of covariances are derived by different methods; the computation accuracy of various algorithms are compared and analyzed.

文章以节点注入功率和PV节点电压运行曲线为基础，依据随机变量数字特征的基本性质和概率潮流计算的相关方程，分别采用不同的方法推导了节点电流、PV节点的无功功率及平衡节点功率的均值和协方差计算公式，比较和分析了各种算法的计算精度。

The theories proposed by Wilson (1994) were adopted to describe the fundamental behaviors of temperature and variation of suction of soil. The Darcy's law and Pick's law described the flows and evaporation of water respectively. Some proposed assumptions including the characteristic curve of volumetric water content and hydraulic conductivity were only related to the suction of unsaturated soil. The coefficient of latent heat for water was a linear function of temperature; and the heat conductivity was calculated according to the equation proposed by De Vries.

对于土体的温度和吸力变化特征，采用Wilson提出的理论加以描述，在此理论中，分别利用Darcy和Fick定律描述水和蒸汽的流动规律，土水特征曲线和水力传导系数假定仅仅相关于非饱和土吸力，水的潜热系数是温度的线性函数，温度传导系数采用De Vries建议方程加以计算。

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％。
