  buccal funnel
aerogenes in high concentration (100 μg ml-1) induces Brachionus to orient their pseudotrochal cirri to form screens over the buccal funnel; this behavior is at least four times less frequently observed at low (10 μg ml-1) food density.
      
The circular and longitudinal muscles of the buccal funnel allow peristaltic movements and probably the rejection of food items not accepted by the mastax receptors.
      
  stomodaeum
Larvae used elaborate feeding behaviors as they pulled solid food particles to their oral opening, broke small particles from larger ones, and took the particles into the stomodaeum, which is a powerful pump.
      
In the stomodaeum, peristaltic movement further macerated the particles, which eventually passed through the cardiac valve into the midgut.
      
Prey are ingested by the negative pressure produced by the rapid expansion of the mouth, and with the macrocilia that line the oral portion of the stomodaeum.
      
The area anterior to the mandibular anlage and posterior to the stomodaeum is occupied by the small anlagen of the intercalary and antennal segments ventrally and dorsally, respectively.
      
The other micromeres contribute only a minor portion of the ventral ectoderm and are involved in the formation of the stomodaeum.

This paper deals with a study on the white speckle disease of garrupa, Epinephe-lus akaara (Temminek et Schlegal). Results are as follows: 1. Pathogen: Petalosoma epinephelis Huang et al. sp. nov. The white speckle disease of the garrupa is caused by a parasitic ciliate. It is foundto be a new species belonging to a new genus of Chlamydodontidae. The ciliates attackthe gills and the skin of the garrupa. The new genus (Petalosoma Huang gen. nov.)possesses both the petaloid body andthe cytostome simultaneously, and so it is quite different from the other five genera ofChlamydodontidae. The type species of this genus is Petalosoma epinephllis Huang et al.sp. nov.. The new species has the body length from 45μ to 80μ (average 67μ) and widthfrom 29μ to 53μ (average 39μ). Its ventral side bears 32-36 rows of cilia. The oralbasketris formed by 12 trichites. There is a petaloid body in the rear of the cell. 2. Symptom: The parasites irritate the skin and gills of the fish, thereby, large quantity ofslime was secreted. The skin appeared white speckles. The infected fish always swimsslow and breathe with difficulty. It would cause high mortality. (a) Bathe the diseased fish in freashwater for 4 minutes.(b) Bathe the diseased fish in 2 ppm. copper sulfate solution for two hours andrepeat text day.

本文报道了对海水经济鱼红点石斑鱼的白斑病的研究结果。 石斑鱼白斑病的病原,是齿管科,瓣体虫属(新属)的石斑瓣体虫(新种)。在齿管科已有纪载的五个层中,瓣体虫属(新属)同斜管虫属和奇异球虫属在形态上较为近似,但是,由于石斑瓣体虫同时具有口管和瓣状体,而明显区别以上两属,故确定为齿管科的一新属和一新种,定名为瓣体虫属(新属)Petalosoma Huang gen.nov.石斑瓣体虫(新种)Petalosoma epine-phelis Huang et al.sp.nov。 病鱼的症状是游泳缓慢,呼吸困难,常浮于水面,头部、皮肤、鳃及鳍上的粘液分泌增多。体表有形状不规则的白斑。这种病的病程短,死亡率高,往往使全池鱼在几天内全部死亡。试验表明,用淡水或硫酸铜海水浸洗病鱼,可以收到令人满意的疗效。

In this paper,a method-ARC method is introduced,by which the development chart can be drawn,of multiple-piece,equal-diameter and right-angled elbows with the radius as the arc of R. And with it, you can draw development chart of the radius of any kind of elbows,the diameter of any kind of pipe openings, and slant opening pipes with any number of pieces and shear position. Moreover, an emphasis is put on the mathematical analysis and comparison between ARC method and calculation method for exact drawing.It has...

In this paper,a method-ARC method is introduced,by which the development chart can be drawn,of multiple-piece,equal-diameter and right-angled elbows with the radius as the arc of R. And with it, you can draw development chart of the radius of any kind of elbows,the diameter of any kind of pipe openings, and slant opening pipes with any number of pieces and shear position. Moreover, an emphasis is put on the mathematical analysis and comparison between ARC method and calculation method for exact drawing.It has proved that drawing the development chart in ARC method is of certain accuracy because of its less absolute and relative errors.And with increasing in pieces as well as in radius of the elbow,its accuracy is higher.Therefore,drawing by this method is simple, flexible and may be of a certain practical value.

本文介绍了一种用半径为R的圆弧绘制多节等径直角弯头展开曲线的方法——圆弧法。该方法能绘制任意弯头半径、管口直径、节数、剪开方位的斜口管展开图。并着重对圆弧法和精确作图的计算方法,进行了数学分析比较,其绝对误差和相对误差都较小,证明了用圆弧法绘展开图有一定的准确性,且随着节数增多、弯头半径增大,其准确度越高,因此,本方法绘图简便、灵活,有一定的实用价值。

This paper makes a systematic study of flooding in vertical tubes with liquid flowing downward and gas flowing upward and defines clearly two types of flooding mechanism of climbing film flooding and liquid bridging flooding. If the velocity of gas is not high enough to cause reverse movement of liquid film, liquid is entrained by gas and forms a liquid slug, i. e., liquid bridge. As the gas stream carries the slug upward, flooding appears. We studied flooding in sharp edged tubes and put forward a semi-theoretical...

This paper makes a systematic study of flooding in vertical tubes with liquid flowing downward and gas flowing upward and defines clearly two types of flooding mechanism of climbing film flooding and liquid bridging flooding. If the velocity of gas is not high enough to cause reverse movement of liquid film, liquid is entrained by gas and forms a liquid slug, i. e., liquid bridge. As the gas stream carries the slug upward, flooding appears. We studied flooding in sharp edged tubes and put forward a semi-theoretical relation. Observation and measurement were done in reflux condensers. The experimental investigation agreed well with the mechanisms mentioned above. An experimental correlation for flooding in tapered tubes was proposed and the flooding mechanism was analyzed briefly. The experiments proved that the flooding velocity could be raised by eliminating entrance disturbance. A new type of tubes with some holes on its ends was developed,

本文较系统地研究了垂直管中的液泛现象,从液泛机理出发,明确定义两种不同的液泛——爬膜液泛和架桥液泛。并侧重研究了管子直径、管口几何形状对液泛的影响。提出平切口管,斜切口管的液泛关联式。指出提高液泛速度的途径。通过实验对所提论点及关联式进行了验证。
