It is suggested that quite a lot of the Be, Co, Cu and Pb could be originated from the syngenetic stage during which the coal-forming plants grew. The strongly seawater-effected peat bog with the reductive and alkaline water could be in favor of the relative enrichment of the Be, Co and Cu, and the faintly seawater-effected bog with the slightly reductive and alkaline water could be in much favor of the enrichment of the Mn, Mo, Ni, P, Pb, Th, Tl and U.

认为凯里煤中相当一部分Be、Co、Cu和Pb起源于成煤植物生长期间的同生阶段;受海水影响强烈的还原偏碱性沼泽环境有利于Be、Co和Cu的相对富集,受海水影响微弱的弱还原性和弱碱性环境条件更有利于Mn、Mo、Ni、P、Pb、Th、Tl和U的富集。

Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.

Media Help Everyday we are exposed to the steam often divided into two, one, the boiler steam - saturated steam 2, thermal power plants out of steam - superheated steam 1, a relatively stable temperature and pressure saturated steam, temperature lower than 250 ℃, working pressure lower than 1.6Mpa 2, superheated steam temperature and pressure changes of a high base temperature up to 400 ℃, working pressure is lower than 4.0Mpa For the first steam, we usually use soft sealing steam solenoid valve as follows: Structural characteristics This valve is a valve and Balance valves main valve by the two vice components with the second open valve Pilot solenoid valve Heat: electromagnetic part, some with special high temperature seals and sealing materials, electrical materials, and apply a variety of insulation measures Wear: selection and reasonable Globe Valves guidance suite valve cup and clever use of fluid lubrication, reduce wear, increase life expectancy Resistance to condensation: condensation of steam pipeline valve on the steam water is an important factor in action, the valve will not affect the condensation water Other uses - soft sealing steam solenoid valve This series solenoid valve can Safety valves be widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research sectors and bathroom, dining room, air conditioning automatic control system.

介质说明日常生活中我们接触到的蒸汽常分为两种,1、锅炉蒸汽-饱和蒸汽 2、热电厂出来的蒸汽-过热蒸汽 1、饱和蒸汽温度压力相对稳定,电动阀门执行器温度低于250℃,工作压力低于1.6Mpa 2、过热蒸汽温度压力变化基数较大温度最高可达400℃以上,工作压力则低于4.0Mpa 对于第一种蒸汽,我们通常会选用氧气专用阀、铜阀门软密封的蒸汽电磁阀如下:结构特点本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀耐热:电磁部分、密封件部分用特种耐高温电工材料和密封材料,并应用了各种隔热措施耐磨:选材合理,电站阀门阀杯和导向套间巧妙地利用流体的润滑作用,减少磨损,提高寿命耐冷凝:蒸汽管道的冷凝水是影响蒸汽电磁阀动作的重要因素,本阀则不受冷凝水影响其他用途-软密封蒸汽电磁阀本系列电磁阀还可广泛地应用平衡阀纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理和科研部门以及浴室、食堂、空调等自控系统。

This paper presents a new chlorine decay model adaptable to the real multi-source network, using Epanet-msx simulation module, comparing the differences in the concentration of chlorine caused by using the same or different chlorine decay rate coefficient of the treated water from different water plants, and then taking the discrepancy of the chlorine decay rate coefficient into consideration will be able to reflect residual chlorine concentration and changes in the network more realistically.

Every year, waters on earth receive large quantities of wastewater from industry, agriculture, fish and poultry raising, and municipal sewage treatment plants. Consequently, the aquatic environment on the earth is under a serious challenge from a very large quantity of pollutants such as antibiotics, insecticides, herbicides, hydrocarbons, etc., contained in the domestic wastewater, industrial and agricultural waste water and illegal effluents. In particular, with the development of intensive aquiculture and poultry, the effluent pollution has recently become more and more serious with more attentions. Furthermore more and more chemical pollutants discharged into aquatic environment have been detected with the advancement of analytical techniques. These chemicals can cause toxic effects on water habitats after discharged into aquatic environment.

每年有大量来自工业、农业、养殖业和城市污水处理厂的废水被排入到水环境中,因此,地球上的水环境面临大量来自生活废水、工农业废水、非法排放的废水及其它废水的污染物质(如抗生素、杀虫剂、除草剂、烃等)的严重挑战,特别是近年来随着集约化养殖的发展,废水污染问题日益突出,并且随着分析手段的进步,能够检测到被排入水环境中的化学污染物质也越来越多,这些化学污染物对水环境中的生物产生有害影响。

The lower limit of water availability is thus determined by the physiology of the plant species and is known as the permanent wilting point – the soil water content at which plants wilt and are unable to recover.

因此可利用水的下限是由植物物种的生理特性所决定的,被称为永久萎蔫点——土壤水含量在这个点上,植物枯死,不能恢复。

Permanent wilting point The point at which soil has dried to the extent that plants can no longer remove the remaining water held on the soil particles,and begin to wilt and will not recover,even if moved to a cool,dark place,unless more water is added to the soil.

永久萎蔫点:指土壤干旱的程度足以引起植物不再能从土壤中吸收水分,开始凋萎,即使是将其移到阴凉、黑暗的地方,也不能再次恢复,除非给土壤中添加更多的水。

Then by Albert Hubei side, in the vicinity of Nimule into Sudan, Malakal, before he is called by the White Nile, through its vast wetlands, impurities contained in the majority of precipitation, water color purity, the water smuggle a large number of aquatic plants The pan-cream, Arabic called Shirakawa.
