In order to investigate the effect of hydrogen on the welding cold cracking in the lowalloy high strength steel, exact measurement of the diffusible hydrogen content in the weld metal has a important meaning,It is well know that the method of measurement is usualy the glycerein method and mercury method. The first method can not exactly measure the diffusible hydrogen content in the weld metal, because the some micro bubbles can not rise and escape from the glycerin medium, so that the quantity collected is reduced and the later not only will pollute envioment but also harm one's health. Therefore it is applied a little in our country. This paper introduces a new metqod. It is called the thermovacc--extraction method. Test procedure was as follows; first, asspecimen was cut in to some pieces as soon as finished the weld, some pieces of them were taken to measure the total hydrogen content in the weld metal by the thermovaccum-extraction method, and remained same nember of pieces were set in to the glycerin medium for 48 hrs(at 45℃), then they were taken out from glycerin medium and measured residual hydrogen content in the weld metal by the thermovacum-extraction method. The total hydrogen content minus the resdual hydrogen content has been defined the average diffusible hydrogen content in the weld metal. The testing result shown thown that the hydrogen content with thethermovaccumextraction method was approximately one time higher than the glycerin method. Therefore this method can collecte all of the diffusible hydrogen content in the weld metal, because it is free from the unfavourable effect of liquid mediumes.

本文推荐了一种新的焊缝扩散氢测定法-真空热抽取法。其过程是,把一条待测焊缝分割成若干块,取其中数块试样作测定总氢量,而把余下的相等数量的试样放入甘油中(45℃)经过48小时后,再取出测定其残余氢。总氢量与残氢量之差,即为焊缝的平均扩散氢含量。试验证实,用真空热抽取法测得的扩散氢量要比甘油法多一倍左右。这表明此方法可以避开液体介质的不良影响,从而有可能把试样中扩散出的氢全部抽集。

Rochrune reacts rapidly with hydrochloric acid in gastric juice and produces a great deal of carbon dioxide micro bubbles, which suspends in the gastric juice.Afterdrinking some watre, the homogeneous gastric juice becomes "foamy" .

Rochrune reacts rapidly with hydrochloric acid in gastric juice and produces a great deal of carbon dioxide micro bubbles, which suspends in the gastric juice.Afterdrinking some watre, the homogeneous gastric juice becomes "foamy" . When ultrasonic wave passes through this area,an intensive reflex will be produced. A complete different state will be seen as compared wiht the normal drinking in non-reflected area.By using this method,the thickness of stomach wall, its shape, the dynamic changes and the diseased area can be well-demonstrated. Therefore it has practical value in diagnostic use.

我们采用中药“海螵蛸”进行胃声学造影通过643例临床观察获得成功。海螵蛸与胃酸中和之后,迅速发生化学反应,产生大量二氧化碳微气泡,悬浮在胃内液体中,使饮水后胃内质地均匀液体变成“泡沫状”液体,超声通过此区时即可产生密集反射,与正常饮水后胃内液体无回声区截然不同,借此,可以确定胃壁厚度、形态、动力改变及疾患所在,它对胃疾病的诊断具有一定实用价值。

The present paper resports a basic re-examination of the thermodynamic principle of collision of free micro-bubbles with flocs and attachment at hydrophobic sites. And according to Levich flocculation theory under turbulent flow condition, a mathematical pattern of flocculation induced by micro-bubbles, suitable for dissolved air flotation system, was developed with taking flocs break-up under a certain intensity of shear rate into account and verified by the experiment. The pattern gave analogul results which almost coincided with the experimental results. Also, it was fountd that if a stream of micro-bubbles introduced into raw water by injecting super-saturated water through a air injection nozzle at, or near, thepoint of addition of coagnlations, it might be possible to obtain a good treatment quality in a flotation tank without any independent floc-bubbles mixing cell within a shorter flocculation period. In this paper the design targets of dissolved air flocculation are provided.

本文论述了微气泡向固体颗粒粘附的热力学原理,并根据Levich紊流絮凝理论,考虑絮体在水流剪切作用下的破碎,提出了一种适用于气浮系统的有微气泡参与的絮凝动力学数学模式。试验证明这个模式与实测值有较好的吻合性。试验结果证明,在絮凝过程的一开始就加入微气泡可大大缩短反应时间,并省去气浮池中所设置的气泡捕捉区,同时取得良好的处理效果。本文提出了加气絮凝池的设计控制指标。
