Because the vibration of pipeline has a great threat against production and safety,the analysis of this phenomenon is favourable for the rational design and management of pipeline system and for taking reliable vibration-proof measures.

管道振动对生产和安全造成很大的威胁。因此，对这种现象进行分析，有利于管道系统的合理设计和管理，有利于提出可靠的防振措施。

The titer test showed that the polyclonal antibodies immunonized by two immunogens all had high titer and the longer interval made for obtaining higher titer. The speciality test showed that the polyclonal antibodies immunonized by conjugations MQCA-RSA had the better speciality than the other one. Usage of RSA as the carrier protein could avoid producing antibody for carrier protein.

以两种偶联物为不同免疫原、采用不同的免疫时间间隔免疫新西兰大白兔，获得多克隆抗体，抗体效价测定和特异性鉴定的实验结果表明：两种免疫原均能产生高效价的抗体，免疫间隔延长有利于效价提高，且以RSA为载体有利于避免针对蛋白载体的抗体产生。

The manufacturing cycle within the GQ10025 heavy load "of ball screw" to replace the fuel tank driver, a driving force for savings | 3-1 | 4 and is conducive to energy conservation and is conducive to environmental protection, can be widely used in metallurgical machinery, mining machinery, Construction machinery, plastics machinery and construction machinery and other equipment.

The results indicated that the techniques of afforestation in plots,container seedlings afforestating and staining roots with phosphate fertilizer haveimproved afforestation survival ratio,height growth and diameter growth of young Pinus elliottii,and Choerospondias axillaris have also been improved by the techniques of staining roots with ABT and cutting stem.

结果表明，有利于提高湿地松造林成活率和促进幼树树高、胸径生长的技术措施分别是集团造林、选用容器苗及磷肥蘸根；而有利于提高南酸枣造林成活率和促进其幼树树高、胸径生长的技术措施为截干和 ABT生根粉沾根处理。

The history classroom activities enormously arouse the students' interests in learning history as well as change the students' learning manners and the traditional "spoon-feed" way of teaching. The variety of classroom activities helps a combined action of the students' four sensory organs, which is also advantageous for the students to improve their ability. They not only help improve the students study, but also help in future development. The interactive process between teachers and students is a foundation of harmonious and democratic relationship between them which helps achieve the goal of progress both teachers and students.

通过开展历史课堂活动极大地调动了学生学习历史的积极性；改变了学生的学习方式，也改变了以往历史教学中&满堂灌&的教学方式；在形式多样的课堂活动中，学生的眼、口、耳、手共同作用，有利于学生各种能力的锻炼和提高，不仅有利于学生学业成绩的提高，还为其将来发展奠定了基础；在师生的互动过程中，构建了和谐民主的师生关系，实现了教学相长的目标。

The optimized sieve parameters reduce the vertical amplitude of the sieve backend, making the grains go easily through the sieve pores to be separated, and consequently help to reduce the grain loss rate and impurity rate.

优化后得到了较优的振动筛参数，有利于减小振动筛后端的垂直振幅，使得谷粒更容易穿过筛孔完成分离，有利于减小损失率和含杂率。

Although centrally is released,add a document that receive about the farmer, emphasize further and give kind of grain farmer clearly to fill continuously, grain market is unlocked in the round etc a lot of be helpful for raising kind of grain farmer to produce the enthusiasm, policy sex that is helpful for commissariat commercializing below element stimulation, 2004, productivity of our country grain can get the gender grows resumptive stage by stage, the farmer is planted the enthusiasm of paddy can get rising for certain, but, from statistic of door of Ministry of Agriculture data of intent of paddy seed-corn establish showed 2004, 2004 of paddy cultivate an area to may increase only 1.3%, visible, in short-term inside the yield that should raise our country paddy considerably still has certain difficulty.

虽然在中心发布关于农民增收的一号文件，进一步强调和明确给种粮农民直补、粮食市场全面放开等诸多有利于提高种粮农民生产积极性、有利于粮食市场化的政策性因素刺激下，2004年，我国粮食生产能力会逐步得到恢复性增长，农民种稻的积极性肯定能够得到提高，但是，从农业部门统计的2004年稻谷种植意向数据显示，2004年稻谷的种植面积可能仅增加1.3%，可见，在短期内要大幅提高我国稻谷的产量仍有一定难度。

The results indicated Paecilomyces farinosus was aerobic fungus and rotate speed of rocking bed exceeded 150r/min would benefit the mycelium growth.Initial inoculum could affect the time of reaching maximal mycelial bioass and could not affect the maximal mycelial bioass.inoculum exceeding 5% would benefit t...

结果表明粉拟青霉是一种好气性真菌，摇床转速大于150r/min有利于该菌生长；接种量对菌丝最大产量影响不大，但是能够影响菌丝量达到最大值的时间；接种量大于5%，有利于菌丝产量迅速达到最大值；粉拟青霉菌在pH值为3～10的培养基中都能够生长，生长过程中能够分泌代谢产物主动调节pH值，该菌在pH为5～7的微酸环境中生长最快；液体发酵过程中粉拟青霉生长量与发酵时间的关系符合逻辑斯蒂生长模型。
