由于盆地演化具周期性，在一个完整的水进-水退旋回中，中间细两侧粗的分界线是两条折线，两条折线结合在一起构成菱形，即所谓"菱形中心"。

During the accident, the main steam pressure drops rapidly, the current and outlet temperature of pulverizer become abnormal.

明确了主蒸汽压力快速下降和磨煤机电流、出口温度异常变化是该类型事故的主要现象，指出石子煤冲洗系统冲洗水采用母管制和系统相关阀门工作环境恶劣造成阀门易磨损卡涩是导致磨煤机进水事故发生的根本原因。

And the explanation of water resistance mainly lie in the cooling water tube blockage, the opening degree deficiency of circulation pump outlet or condenser water inlet valve and the devastation of circulation pump siphonage, etc.

而水阻增加的原因主要是由于冷却水管堵塞，循环水泵出口或凝汽器进水阀门开度不足，以及循环水泵虹吸遭到破坏等原因造成的。

The result of anaerobic baffled reactor treating low strength wastewater on mesophilic condition indicates that on the condition of influent CODCr concentration of about 500 mg/L,HRT 3～12 h,the reactor was efficient in the removal of CODCr,viz above 84%,effluent CODCr concentration of 75 mg/L.

对厌氧折流板反应器在中温条件下处理低浓度废水的试验结果表明：在进水CODCr浓度为500mg/L、水力停留时间为3～12h时，CODCr的平均去除率可达84%，出水CODCr浓度可降至75mg/L。

The results indicates, with the same level of other parameters, the TN removal can reach 80.0% and 70.9% with the control of dissolved oxygen under the levels of 0.3-0.6mg/l and 0.6-0.9mg/l, respectively; the TN removal upgrades from 80%, 83% to 84.1% with the decrease of sludge load in the system from 0.1, 0.07, to 0.05gCOD/gMLSS·d; the nitrogen removal only reaches 58% when C/N is 4, but can reach more than 80% when C/N is at or over 7, which indicates that the TN removal increases when higher C/N ratio; when HRT increases from 12h, 18h to 24h, the TN removal also increases from 78.6%, 82.0% to 83.0%; the TN removal average in the system increases from 75.6%, 78.5% to 83.0% with the increase of sludge age from 18d, 20d to 24d; the low oxygen conditions in the modified Orbal oxidation ditch model do not decrease the effect of COD removal, and the dissolved oxygen gradient with the distribution of 0-2-1mg/l in the system ensures the COD removal reaching the range of 80%-86%; and the phosphate removal, however, is not good enough, which varies from 40% to 50%, even lower than 35% in occasional situations, and the phosphate concentration in the outflow varies in the range of 1.28-2.38mg/l, which dissatisfies the discharge standard with the level of 1.0mg/l.

试验结果表明，在其它参数相同的情况下，将外沟道的溶解氧分别控制在0.3～0.6mg/l 和0.6～0.9mg/l 两个水平，外沟道中TN 去除率分别为80.0%和70.9%；系统中污泥负荷分别为0.1gCOD/gMLSS·d、0.07 gCOD/gMLSS·d、0.05 gCOD/gMLSS·d时，随着污泥负荷的降低，TN 的去除率却是上升的，分别为80%、83%、84.1%；本试验中，当C/N 为4时，仅能获得58%的脱氮率，当C/N 为7 或更高时脱氮率能达到80%以上，进水C/N 比值越高，总氮的去除率越高；在本试验中采取的水力停留分别为12h、18h、24h 时，外沟道中的总氮去除率随水力停留时间的增加而增加，分别为78.6%、82.0%和83.0%；当系统泥龄分别为18d、20d、24d 时，系统平均TN 去除率分别为75.6%、78.5%、83.0%，随着泥龄的增大TN 的去除率增加；改良型奥贝尔模型的低氧条件并没有降低COD 的去除效果，系统0-2-1mg/l的溶解氧梯度分布使得COD 去除率一般都在80%～86%之间；本试验中磷的去除效果不好，去除率基本在40%～50%之间，有的甚至低于35%，出水磷的浓度在1.28～2.38mg/l 之间，低于1.0mg/l 的出水排放标准。

If I jump into the water, it comes up to my armpits and holds up my cheeks.

如果我跳进水里，水到达我的腋下托起我的脸颊。

According to the long-term detection on the influent of the plant, the concentration of organic substance is insufficient (BODs is about 60 mg/1.). The wastewater is improper for the conventional active sludge system. But, the contamination removal of existed normal primary treatment is inadequate.

根据厂方对进水水质进行的长期监测，进水有机物浓度偏低(BOD_5一般在60mg／L左右)，采用现有的活性污泥法处理工艺，污泥负荷偏低，不利于活性污泥法系统正常运行，而常规一级处理污染物去除效率又较低。

The results of the test show that. HYDRAcap60 UF can effetely remove the suspended solid and reduce the content of colloid in the circulating cooling water. The quality and the quantity can meet the requirement of reverse osmosis system.

结果表明，HYDRAcap60 超滤可有效去除循环冷却排污水中的悬浮物、降低胶体含量，产水的水质、水量完全满足反渗透膜进水要求。

A low cost process for municipal wastewater treatment using a new porous concrete eco-film membrane biological bed was studied. The system operated with inflowing continuously and recycling partly. The results showed that the removal efficiency of CODcr, BOD5, NH3-N and TP was 82％, 84％, 83% and 33%, respectively.

采用新型低成本渠式透水混凝土生态膜反应床处理城市污水，以连续进水，部分回流的方式运行，对CODcr、BOD5、氨氮和TP的去除率分别为82％、84％、83％和33％。

The trace amount of impurities,namely C5,tert-butyl alcohol,di-secondary butyl ether,methyl ethyl ketone and secondary butyl alcohol,in C4 hydrocarbon from butylene hydration tail gas were analysed by means of gas chromatograph with a column packed with sebaconitrile and polyethylene glycol-20M,and liquid-phase admission valve.

2m×4mm为填充柱，采用液相进样阀液态直接进样的填充柱气相色谱法分析了丁烯水合尾气C4烃中的C5、叔丁醇、二仲丁醚、甲乙酮及仲丁醇等微量杂质的含量。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
