结果表明：①在干燥过程中，HXD喂料点前工艺气流与烟丝间的换热量可用干燥前后工艺气流温差的倒数来衡量；②在其它控制参数不变，只改变排潮模式的情况下，设置为手动控制排潮时，干燥过程的换热量总是较低；③当设置为自动排潮且HXD蒸气注入量超过1800kg/h时，工艺气流的干燥能力随着注入量的增大而降低。

Considering the spatial correlations of interconnect process variations, we modelprocess variations as continual stochastic processes with correlation. For decoupleing thespatial correlation, we express them as an expanded form of independent random variablesby Karhunen-Loeve expansion. Then we use stochastic Galerkin method to solve thedecoupled telegraph equation in the presence of process variations.

The investigation on the concentration of four haloacetic acid s during conventional water treatment process in waterworks and in drinking waters in North China showed that there were only dichloroacetic acids and trichloroacetic acids in waters,and the proportion of TCAA was from 52% to 90%.

对北方某自来水厂常规水处理过程及饮用水体中的4种卤乙酸质量浓度进行了调查，结果表明水体中只存在二氯乙酸和三氯乙酸，其中三氯乙酸所占比例较大，为52%~90%；常规水处理工艺对二氯乙酸有较为明显的去除效果，去除率在15%以上，而对三氯乙酸没有明显的去除效果，但总体而言其对卤乙酸有10%左右的去除率；预氯化对卤乙酸的产生起主导性作用，该处产生的卤乙酸占整个氯化过程产生的卤乙酸总量的60%以上，因此常规工艺有必要从预氯化工艺着手加以改进，来更好的控制卤乙酸的产生量。

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。
