市前准备是宴会顺利完成的保证

宴会有各种类型,以规模分,有小型、中型、大型;以形式分,有中餐、西餐、冷餐会等等。但不管何种宴会,要顺利地完成接待任务,市前准备工作十分重要。仔细、充分、周到的市前准备是保证宴会顺利进行的基础。常言道:“不打无准备之仗”,我们做宴会工作。也和打仗一样,有一个先了解情况然后根据掌握的情况,再作周密步署的准备过程。情况了解得越全面,准备得越充分。

提高母牛受胎率的配后洗

我站每年都平均有250头奶牛参加配种,但由于胎衣停滞、难产等原因造成子宫炎的难妊牛数每年都在10—15%左右,这给配种带来极大的困难。

酸性气体脱除单元副产二氧化碳中夹带甲醇的去除方案研究

酸性气体脱除单元副产的二氧化碳可作为粉煤气化装置载气循环利用,但其夹带微量甲醇,需经过处理才能达标排放。以某二氧化碳需求量为20000 m^(3)/h的粉煤气化装置为例,分析对比了压缩机段间洗涤和压缩前洗涤两种水洗法脱除二氧化碳中微量甲醇的方案,结果发现水洗法脱除甲醇的方案可行,且压缩机段间洗涤方案较压缩前洗涤方案安全性更高,设备费用更低,能耗低15.5%,每小时可省操作费用105.1元。初步探讨了吸附法用于脱除二氧化碳中微量甲醇的可行性。

Research and Application of Even-Drive Washing Technology

In this paper, the development history and existing shortcomings of washing machines have been briefly described, the operating principle of the current washing machines has been analyzed, user requirements and the direction of industry development have been found out, and the even-drive washing technology has been studied out through adoption of hyperbolic impeller and suspended inner barrel structure, as well as high-efficiency drive and innovated control design. Thereby the problems with existing washing machines such as heavy twist and wear, uneven wash of clothes, long washing time, and high water and power consumption are solved.
