Field application result shows that for eccentric screw stabilizer , there exist errors of calculated outside diameters and measured diameters , the upper stabilizer has severe influence on side force of drilling bits , and it can be optimally designed , while the bending angle of screw also has severe influence on bit side force , and it should be rationally used 现场使用结果表明，螺杆本体稳定器采用偏心式时计算外径与丈量直径存在偏差；上稳定器对钻头侧向力具有较大的影响，可以优化设计；螺杆弯角对钻头侧向力影响较大，需合理使用。
Risheng always focus on the flexibilities of pattern - making when analyses the new needs . and we are exploring a more effective and enforceable way to have some breakthrough on side of high - flexibility and high - relevancy of the previous system and remove all of limitations of the previous software . the frame of the new system nacpro is finally born after repeatedly argumentation and experimentation , which aim at the characteristic of apparel cad , and exploitation of combination of all kinds of statistics structure 在分析新需求方面，日升软件始终比较重视打板的灵活性，但如何对原有系统在打板的高灵活性和高关联性方面有所突破并能消除以往软件的所有制限，一直在寻找更为有效和可实施的方法，经过反复论证和实验，针对服装cad的特点和对各种数据结构相结合的探究，终于通过新产品nacpro的新框架结构得以实现，这的确花费了许多周折，然而研发的道路本身就不可能是一帆风顺的，尤其是有了已经很成熟并被市场所认可的nac2000 。
The root system of malus toringoides is so developed that it can grow on prior soil and in cracks of rock . like malus transitoria , malus toringoides tolerant to draught and can grow on sunny dry slope , rocks of steep cliffs , barren stone area , roadsides and field sides . malus toringoides was also adapted to habitat shade and can grow normally gorges of hill , and even on sides of brook and river , where water often attack on 变叶海棠根系发达，能穿透坚硬的土层和岩石裂缝，它具有喜光耐旱的特点，在阳坡、凸坡、悬崖峭壁、瘠薄坚硬的石谷子地、道路两旁和农耕地边都能正常生长，与花叶海棠近似；变叶海棠也具有喜湿耐阴的特点，在深山峡谷、甚至在根系长期经受洪水侵袭的溪边、河岸也能正常生长，与陇东海棠近似。
Then we set up the model of rectangle - shape pipeline . we compare it to circuit - shape pipeline on sides of the value of induced electromotive force , pressure loss when liquid flow trough the pipeline and resistance ' s value of the sensor . we get the result that we can finish the measurement of low - velocity flow by using the rectangle - shape pipeline 接着对矩形测量导管进行建模，并在流体流经矩形测量导管时产生感应电动势的大小、流体在测量导管中的压力损失和传感器内阻的大小对输出信号的影响等几个方面与圆形测量导管进行比较后得出采用矩形测量导管完全能够有效地完成微流量的测量。
This paper describes the structure , technical features and technical requirements of manufacture of a gasification stove with four contraposition burners on side walls , expatiates on its manufacturing process , key techniques and quality guarantee measures such as barrel formation , machining , assembly welding , heat treatment , subassembly secondary machining and precision detection 摘要气化炉是煤化工的核心设备，大庆油田金属结构厂与哈尔滨锅炉厂合作，为某大型石化企业制造了一台侧壁4个烧嘴对置式新型气化炉，该气化炉是目前国内同类产品中最大的气化炉。
