真空冷凝器

In addition, as the secondary steam get in direct contact with the ejection flow to carry out heat exchange, most steam is condensed into water, while the uncondensed small minority steam and the uncondensed gas will also get into friction, with the high speed water ejection, mixed and extruded, then discharged through diffusing pipe, thus to form up higher vacuum inside.

另外由于二次蒸汽与喷射水流直接接触，进行热交换，绝大部分的蒸汽凝结成水，小量未被冷凝的蒸汽与不凝结的气体亦由于与高速喷射水流互相摩擦，混合挤压，通过扩压管被排除，使器室内形成更高的真空。

It is prepared by the steps: using vacuum machine set to vacuumize the reaction chamber, then charging protective gas to generate electric arc between moving electrode and metal Pb, and quickly condenses Pb steam to deposit Pb powder in powder collector.

本发明所述的铅粉按以下步骤制得，用真空机组对反应室抽真空，再充入保护气体，在运动电极与金属铅之间产生电弧，对铅蒸气快速冷凝，沉降至收粉器中。

Tsurumi / Su Village Water Ring Vacuum Pump Tsurumi introduce characteristics was founded in 1924, professional manufacturer of water ring vacuum pump and compressor, condenser vacuum in the power plant have a wide range of applications, especially in Japan, the local electric plants, most of them are used in vacuum pumps Tsurumi.

鹤见创建于1924年，专业制造水环式真空泵和压缩机，在电厂冷凝器抽真空上有着广泛的应用，尤其是在日本本土的电厂，绝大多数都采用的鹤见真空泵。

The system is maked up of steam pot , condenser and producing by vacuum material pump , vacuum pump ,etc..

该系统主要由真空闪蒸罐、冷凝器及相应的出料泵、真空泵等组成。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
