We investigated the transformation of the flow field with the increase of centrifugal force . when the acceleration became bigger , the flow field has a main circumfluence of anti - clockwise and a circumfluence of clockwise on the downriver 研究了流场随着加速度增加的变化情况,随着加速度的增大,当离心力与流速方向相同时,流场有一逆时针方向的主回流区,在流场下游有一顺时针方向的回流区。
A rig was designed on the basis of thermodynamic analysis . some factors , including mixture composition , cycle compression ratio and suction ratio of circumfluence fluid of the rectifying column , are analyzed of their impacts on coefficient of performance 在对新循环进行了热力学分析的基础上,设计了自动复叠制冷循环实验台,分析了循环工质配比、循环压比及精馏柱回流液的抽取率对循环系统cop的影响。
It is applicable to the network in which the circumfluence exists . pricing of active and reactive power is integrated efficiently . the problem that how to recover the cost of the generators which operate in the under excitation condition is resolved successfully 该方法适用于存在环流的网络,有效地解决了发电机进相运行时生产的成本回收问题,并将负荷有功、无功电价计算有效地统一起来;它计算简单,实用性强。
In the 1960 ' s , the circumfluence theory has been used to design the shroud - propeller , and it can be divided to two methods , one is that the profile of die shroud is provided , the other is that the pressure distribution of the shroud is provided . 到六十年代,函道螺旋桨的环流理论就可用来计算这种推进器的设计问题。本文中使用的方法是:函道用圆环涡系和圆环源、汇系模拟,用线性理论计算;螺旋桨用一个变负载的鼓动盘模拟。
At present when migration of surplus rural labor is slow and even of circumfluence , the two - dwelling on flow but not migrated transfer undoubtedly result from which many factors are working together , but education level of rural labor is an important piece of constraint 目前,农村剩余劳动力转移缓慢甚至出现回流,其两栖式的流动而非移民型的转移无疑是多因素共同作用合力的结果,但农村劳动力的教育水平是一个重要的制约因素。
( 3 ) the polar eddy , the west circumfluence on 500hpa medium latitudinal region ands subtropic circumfluence are the key systems of tpnes floods precipitation and , the wet years have abundant vapor , moreover , the omga is positive in all atmosphere ( 3 )极涡、中高纬西风环流系统和副热带系统是影响青藏高原东北侧区汛期降水的大尺度环流背景关键系统。同时,多雨年的主要流场特点是有利于水汽输送,且整层大气始终表现为上升运动。
It is the important mechanism that middle - level dry and cold air current sunk , low - level warm and wet air current ascended . level direction energy sharp section is important to blaze middle scale hypo - circumfluence . severe convection weather was brought by layer - knot latent instability 上层干冷、下层暖湿的位势不稳定层结可以使对流层中低层出现明显的逆温层,有利于不稳定能量积累,此次天气过程产生的对流不稳定能量大,形成的上升气流深厚。
Sichuan is one of the agricultural province , locates in the area between the continental climate and oceanic climate , the distribution of precipitation is always disproportional due to the influence of atmosphere circumfluence , the existence of drought and floodwater plus water pollution have produced huge menace to agriculture , water resources utilization , soil erosion and even the life and properties of human being 解决水资源的诸多问题,是摆在全党、全社会和全国人民面前一项刻不容缓的重大战略任务。四川作为贫水国的一个农业大省,由于地处海洋性气候与大陆性气候交接地带,受大气环流影响,降水时空分布不均,水旱灾害极为频繁,尤其是干旱对农业生产的威胁最大。
The device is to service at such industries as china traditional drug , food stuff and chemistry for the technologies such as normal pressure 、 mini pressure , water decocting , warm immersion , thermal circumfluence , compelled recycle and leakage , extraction of aroma oil and reclamation of organic solvent with the features of high efficiency and convenient operation , the cipcleaning system inside the tank meets with the gmp standard 本设备适用于中药、食品、化工行业的常压、微压、水煎、温浸、热回流、强制循环渗漏作用,芳香油提取及有机溶煤回收等多种工艺操作,具有效率高、操作方便等优点,罐内配备cip清洗系统,符合gmp医药标准。
