Fixed bed ion exchange has been widely used for many years for particularly favorable processes.Unfortunately improving the conventional fixed bed process leads at best to a poor suboptimum.The selection of huge unconfined beds, coarse resin,long cycles,high loading,backwash,and cocurrent operation result from constraints which themselves result in a cyelic manner from these very conditions.The pratice of Reciproeating Flow lon exchange(RFIE),involves none of these and the result is a dramatic improvement in efficiency,bed size,and range of application.In particular conventional fixed bed process has been limited to processes where a large shift in the equilibrium makes both take up and regeneration quite favorable. A quantitative simplified model for ion exchange followed by a qualitative discussion of added complexities forms the basis for understanding the relationship between cocurrent and countercurrent operation for various loadings,regenerant ratios and number of stages;and comparing various fixed and moving bed ion exchange systemes.The simplifications which clarify the results with this model include restriction to but two cycles,take-up and regeneration,one nutuber of stages and one constant equilibrium(relatively unfavorable)for hoth of these cycles.This both reduces the number of parameters and emphasizes the differences.A number of figures illustrate the relationships and clearly show not only the small improvement of countercurrent operatipm pver cocurrent operation found at high loading,but also the much greater improvement as the loading for countercurrent operation is decreased to 10% or 20%.Low loading coupled with fine resin(100—200 mesh), short beds,short cycle times,etc.,make it possible to eliminate backwash,to coilfine the bed and to operate countercurrently. The pattern of performance displayed by the simple model matches that observed experimentally for the recovery of uranium.The model provides a good basis for understanding and extending these experimental results and to understand other advantages of RFIE such as greatly reduced attrition of the resin,and ability to operate with both the pregnant and regenerant solutions as concentrated solutions.

多年来,固定床离子交换法已经在若干特别适应此法的流程中广泛应用。遗憾的是对传统的固定床流程所作的改进至多只能达到相对落后的次最佳化水平。由于制约条件的限制,固定床占地庞大,循环周期长,负荷高,所用树脂的颗粒粗大,需要返洗,使用并流操作,而这些情形本身又成了限制条件。采用往复离子流交换法(RFIE)则完全不受上述条件的限制,同时还在改进效率、缩小床层尺寸以及扩大应用范围等方面取得出色的效果。严格说来,传统的固定的流程只限于在平衡移动程度很大,从而对交换及再生十分有利的流程中才可以应用。探讨各种不同负荷、不同再生剂比及不同级数下的并流和逆流操作之间的关系的依据,是本研究中所运用的一项简化的定量离子交换理论模型结合了加拿大系统的复杂性后的定性讨论;此外还对各种固定床式及流动床式的离子交换系统进行了对比。使用上述理论解释本文结果时所作的简化包括限于两个循环的交换和再生过程,每一循环只研究一种交换级数、一种恒常平衡。这种简化的做法既减少了参数,也突出了两类流程的差别。本文所附诸图显示两种流程之间的各种关系,而且不仅清晰表明在高负荷时逆流操作与并流操作相比较略有改进,还表明当逆流操作的负荷降到10%或20%时,这种改进就...

Three hundred eighty breast-feeding mothers nursing thier infants under one year old were investigated by case method in the East District of Guangzhou city. About 53.3% of the mothers breast fed thier babies and 35.4% using mixed feeding and the remainder 10.8% artificial feeding.Mothers chose multifarious foods for their daily diets, including meat, eSS> poultry and fish; milk and milk products; soybean and its products; different kinds of vegetables and fruits; wines; sugar; cereals (rice and wheat) and the traditional dish made with the ingredients of ginger, Chinese vinegar and pork.It seemed that there was some correlations between the milk secretion of the mothers and the money expended for their diets among the breastfeeding women (P<0.05), but for the meat, egg, poultry and fish consumptions as a whole item, no significant difference can be found between a con-sumptionat level of 8 kilograms and a level of 14 kilograms or more per month with the other foods available. It means that 8 kilograms of different animal food for one month is a good basis. Mothers accustomed to put the stress of eating more food especially meats and poultry in the first month after delivery, about 40 to 50 grams of protein from animal origin was provided generally in this time but took little care on the diets for the second month and later, only one half of the animal protein was obtained as compared to the first month by the end of the sixth month of breast-feeding. The problem was discussed.

本文调查了广州市一个街区380名乳母的饮食习惯。在380名乳母中,愿意用母乳喂养孩子的母亲占89.2%,但在四个月内能单独以母乳喂养孩子的仅占53.8%。乳母饮食习惯与其乳汁分泌状况有一定的关系。大部母亲都注意并取得较好的营养照顾。产后在饮食上合理补充与未注意必要的补充者差别明显(P<0.01),但摄入肉、蛋、鱼类食物每月共计在16市斤以上时,再增加此类食物的食入量未见有明显的影响(P>0.1)。单独注意肉食并以大量这类食物集中于产后第一个月,对第二个月以后的营养不予重视的饮食习惯是不合适的,哺乳母亲对豆类、蔬菜、奶类的合理食用是一个值得注意的问题,本文作了讨论并认为对哺乳母亲饮食的指导是重要的。
