The inclined wire former is the forming device and key part of inclined wire machine and is also the different part from other paper machines. Study on the inclined wire former is very important in the research on the inclined wire machine.

因为国内还没有较系统的理论，所以本文对斜网成形器的机理和设计研究，是通过大量的造纸原理、造纸机设计理论、机械学原理、流体力学等，并结合作者多年来对纸机设计的经验，来进行斜网机理的探索和斜网成形器的设计要求分析的。

Zhang Min:"TrumpJet" technology sets the dosing point of wet end chemical additives at the outlet pipe of machine screen of the head-box, and uses Booster pump to extract stock as dilution media, and uses "TrumpJet" mixing to inject chemical additives into Headbox loop, which dexterously uses energy of stock in Headbox pipelines, making a very low power consumption in Booster pump (only requires the energy of speeding up for chemical additives flow), eliminating large volume of chemical additives for fresh water dilution, and chemical additives and stock can be fully mixed within 2 seconds, and delivered to model for shaping at the maximum of chemical additives efficiency.

在数千年的造纸发展史上，传统的湿部化学品的加入和混合一直是利用加后稀释水的方法通过静态在线混合器来完成的，由于湿部化学品的加入量很小，，其流量仅为 0.1~1升/秒甚至更小，而要将如此之小的流量加入到纸机流浆箱300 ~2000 升/秒的工艺系统浆料流体中，同时达到化学品与造纸纤维均匀接触，即使是消耗大量的清水和使用在线混合器也很难达到&完全&且&有效&地混合，于是就又产生了将化学品的加入点，提前到远离流浆箱的工艺位置，这样可以延长混合时间，但人们忽略了在过早加入化学品的同时也带来了化学品的流失、化学品在短循环系统循环产生有害副产物生成浆管悬挂、化学品水解失效等一系列弊病。

These results provide the scientific basis for determining suitable irrigation frequency and the irrigation volume of papermaking wastewater in saline reed field of Yellow River Delta, which is of great significance to the exploitation and utilization of papermaking wastewater resources.

该研究为黄河三角洲内陆盐碱地区芦苇群落在造纸废水灌溉下的适宜灌溉次数和灌溉水量的确定提供了科学依据，有利于造纸废水资源的合理化开发利用。

To study the effect of papermaking wastewater irrigation on soil hydrological properties in saline reed field, different wastewater irrigation frequencies were employed in the saline reed field of Yellow River Delta. Soil infiltration course and hydrological properties were determined in field and laboratory. After wastewater irrigation, the change of the soil pH value, soil salt content and soil hydrologic-physical properties were observed. The results were showed that: 1 After wastewater irrigation, the mean reduction of soil pH value was 6.0%.

为研究造纸废水灌溉对黄河三角洲内陆盐碱芦苇地土壤水文特征的影响，通过设置芦苇地不同废水灌溉次数下的随机区组试验，采用田间测量土壤入渗过程和实验室内测定水文物理参数相结合的方法，分析造纸废水灌溉前后土壤pH值、含盐率及土壤水文物理参数的变化。
