In this paper, Gilsonite modified asphalt mixtures are manufactured by various dosage of Gilsonite being added during the dry cycle of the mixing procedure onto the hot aggregate rocks before bitumen being added,and then the Gilsonite modified asphalt mixtures are researched on their road performance.

采用不同用量的北美岩沥青在高温条件下对石料进行预拌裹覆，然后再添加沥青和改性沥青拌制成沥青混合料，并对其各项路用性能进行了对比试验研究。

Squeezing and preparing a plate underframe and a upper holdfast with support legs respectively, pre-sintering and final finishing the underframe and upper holdfast respectively, then welding the underframe and the upper holdfast of upper holdfast into one unit, finally heat treating the welded one unit product under the temperature of 150-650DEG C.

分别挤压制成一个平板形底架和一个带有支撑腿的上支架，将底架和上支架分别预烧结、精整，然后，再将底架和上支架的支撑腿烧结焊成一体，最后在150～650℃的温度下将焊接为一体的产品进行热处理。

In this paper, the flax yarn will be used as the continuous reinforcement and the Polypropylene multifilament will be used as thermoplastic resin matrix. The two things will be made into a pp/flax covered yarn, which are ready to be woven into a plain fabric. The flax/pp composite board is accomplished by hot-pressing molding. Some other composite boards are also made, whose flax yarn haven been pretreated.

本课题将以亚麻纱线作为连续状增强体，聚丙烯复丝作为基体；采用包覆纱的浸渍工艺，制作了pp/亚麻包覆纱后浸料；再将包覆纱制成机织平纹布作为预成型件；通过热压成型工艺制作成复合材料板材；同时还制作了对亚麻纱线进行碱处理和偶联剂处理的复合材料板材。

Reparation of PBO was begun with the polymerization process in which composite salts that contained 4,6-diaminoresorcinol and terephthalic acid were dissolved in polyphosphoric acid and phosphorus pentoxide.

BO纤维制备：以4，6-二氨基间苯二酚的盐酸盐为单体原料，与对苯二甲酸混合，经过中和反应、脱色处理、干燥后制成复合盐；再以多聚磷酸为溶剂，添加五氧化二磷和抗氧化剂，经过预聚合反应制备出PBO聚合物；聚合物通过双螺杆挤出机进一步进行聚合，然后通过喷丝板挤出，在磷酸水溶液中凝固成型，经过洗涤、干燥等过程，最终卷绕成型。

A stable, water-insoluable film was prepared by oxidative electropolymerization of pyrogallol in pH7.0 phosphate buffer solution, anti modified on a glassy carbon electrode surface by electrochemical method. The modified electrode was exploited for the selective preconcentration of Cu at a certain potential. The preconcentrated Cu was firstly reduced at a certain potential and then was determined by differential pulse stripping voltammetry.

采用电化学方法在pH7.0磷酸缓冲溶液中，将邻苯三酚氧化电聚合制成稳定的水不溶性膜修饰在玻碳电极表面，将制得的膜修饰电极在一定电位下选择性预富集铜，并用差分脉冲溶出伏安法测定。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
