Combined with CAD software development of grids,the design method of bolt-sphere joint is put forward based on geometry restriction and intensity restriction. The geomitry dimension of each component is determined firstly based on bolt diameter and contexture, then, maximal pull and stress of diversitied bolt are given after intensity restriction of all components is taken into acount.

在网架结构中,节点起着连接汇交杆件、传递屋面荷载和吊车荷载的作用,而网架结构属空间杆系,汇交于一个节点上的杆件至少有 6根,多的可达 1 3根,各杆件间的夹角大小不同,且节点各构件间的几何关系或强度关系相互制约,使得节点设计十分繁杂。

Plumber-Neck The plumber-neck is characterized by a horizontal bend just below where the end of the shaft and the hosel meet. This design, which generally provides a medium amount of offset, does a great job of keeping the hands ahead of the clubhead through impact. This tends to make the putter more forgiving and easier to use, which is the reason it's so popular.

Plumber-Neck:该特点在於在杆身末端与杆颈连接的地方有个水平转折处,这样的设计提供了中度的OFFSET,这样的设计能让手在击球时永远在杆头前面,这会让推杆有更大的容许误差量并更容易去使用她,这也就是为何这种杆颈造型成为受欢迎的原因。

Chicken IL-15(ChIL-15), Which was discovered in 2001, plays a main role in activating NK cells and CD8+ memory T cells, and may therefore have potential as a vaccine adjuvant.According to published ChIL-15 gene sequence, a pair of primers were designed and synthesized to clone ChIL-15 cDNA from ConA-activated chicken splenocytes by RT-PCR. Recombinant plasmid pUC19ChIL-15 carrying the ChIL-15 gene was constructed. The gene encoding mature ChIL-15 (mChIL-15) was amplified from pUC19ChIL-15 by PCR and cloned into pMD 18-T vector. After digested with Kpn I /Pst I , the mChIL-15 gene was subcloned into prokaryotic expression vector pPRoEX橦Ta and transformed into E.coli DH5a .The transformant was induced by IPTG, and the recombinant ChIL-15(rChIL-15) was expressed as a fusion protein with a histidine hexamer tag at the N-terminal end of the protein. Following expression, the protein was purified by ProBond?Nickel-Chelating Resin. The uninduced and induced protein lysates and the purified protein were separated by SDS-PAGE and transferred onto nitrocellulose membrane to identify rChIL-15 by Western blot. The rChIL-15 was used to immune the guinea pig to obtain rChIL-15 polyclonal antibody.
