driving force

As the existing models are insufficient to accurately describe the mechanism, a comprehensive model is advanced in this paper to evaluate the relative static pressure and driving force of the solar chimney power plant systems, in which the effects of various parameters on the relative static pressure and driving force have been further investigated.

由于现有模型不足以准确描述太阳能热气流发电系统的物理机制,本文提出一个更完善的数学模型去分析太阳能热气流电站系统的相对压力分布和系统抽力。

The results show that the appropriate off-gas pressures in the periods of emerged arc and submerged arc are -200-250 Pa and -120 Pa, respectively.

结果表明:露弧加热期和埋弧加热期炉盖的合理抽气压力分别为-200~-250Pa和-120Pa;底吹氩气量过小不能在液面上部弥散,而增大到20~50m3。

In the heating period of emerged arc, appropriate off-gas pressure is more than 250 Pa and high temperature zones in the middle of lid is big.

结果表明,进入炉盖内的气体在主体部分流动规律是一致,露弧加热时达到硝烟除尘要求的合理抽气压力为250 Pa 以上,炉盖中部局部高温区域大温度高,埋弧加热期合理抽气压力为200 Pa 左右,炉盖壁面温度低得多,中部温度高温区仅为330 K(57℃)左右。

The results showed that the t_(10)and t_(90)of rubber compound extended a little by using superfine active kaolin partly instead of carbon black in inner ply and outer ply compounds,and the physical properties of vulcanizate and H pull-out after aging changed little;the endu-rance of finished tire improved and the cost of rubber compound reduced.

结果表明,在内层和外层帘布胶中以超细活性高岭土部分替代炭黑后,胶料的t10和t90稍有延长,硫化胶的物理性能及老化后H抽出力基本相当;成品轮胎耐久性能提高,胶料成本降低。

The results showed that the scorch time extended,the curing speed reduced,the anti-reversion improved,and the better tensile,elongation and tear properties were obtained using TBSI instead of TBBS by equal weight in the upper bead filler compound;and the scorch time extended,t_(90) reduced,the permanent tensile set decreased and the H pull-out changed little using 1 phr of TBSI instead of 1.

在胎体胶配方中以 1份促进剂TBSI替代 1 2 5份促进剂DZ ,胶料的焦烧时间延长 ,t90 缩短 ,硫化胶的拉断永久变形减小 ,H抽出力相当。

The results showed that when compared to the dry cobalt decanoate,the wet cobalt decanoate gave NR vulcanizate higher H pull-out force,lower H pull-out force loss after hot air aging and brine aging and similar physical properties.

结果表明,与干法工艺生产的癸酸钴相比,采用湿法工艺生产的癸酸钴可提高NR硫化胶的H抽出力,经热空气老化和盐水老化后硫化胶的H抽出力下降率较小,其它物理性能基本相当。

It also states modifying formula of the taking out force and compares calculation examples.

本文提出了在塑料注射模中斜导柱侧向分型与抽芯机构抽拔力的计算时,应按侧型芯滑块在侧向分型方向的垂直面的投影面积计算,并给出了抽拔力计算的修正公式并通过计算实例比较证明该公式的合理性。
