By use of site mutation strategy and PCR technology, we obtained the gene P12X3C that includes full length P1, 2A, 3C and a part of 2B and 3B and the gene P12X3C3D that includes full length P1, 2A, 3C, 3D and a part of 2B and 3B. After being digested by restriction enzyme respectively, the gene P12X3C and the gene P12X3C3D were cloned into the pcDNA3. 1 and pTARGET expression vector that were digested by the same enzyme. Recombinant plasmids were checked by restriction enzyme analysis and nucleic acid sequencing. Further more, recombinant plasmids were transfected into BHK-21 cells by using lipoid. The proteins of foot-and-mouth disease virus , which were expressed in BHK-21 cells, were confirmed by sandwich-ELISA and fluoroscopy, and the capsid of FMDV was tested by electron microscope. In order to evaluate enhanced immune response of guinea pigs against FMDV, DNA vaccines which were designed to produce viral capsids lacking infectious viral nucleic acid and contained the gene P12X3C and the gene P12X3C3D were injected respectively with FMDV 3D protein which was expressed in Pichia Pastoris Secreted expression System and purified or with pcDNA3. 1/IFN which includes the gene IFN-α of cattle. Subsequently, Recombinant plasmids were injected to cattles with or without pcDNA3. 1/IFN. Anti-FMDV antibodies were detected by ELISA, and the T lymphocyte proliferation response was tested by MTT assay, neutralization antibodies titers were analyzed by micro-neutralization assay.

Because the light power in claddings is weaker than one in core, the overlap will weaken when modulation is realized only in cladding.

由于包层中光波强度比芯层中要弱，因此在包层中调制光波会引起场模交叠因子的弱化，但是优化计算发现，通过调节波导的尺寸尤其是芯层厚度可以控制交叠因子使其弱化程度降低到最小，在最优的情况下，场－模交叠因子可达0.89。

They've been mailing tea bags to Congress to I guess express their dissatisfaction with taxes and government spending because nothing shakes a politician up like a complimentary bag of tea.'Hey if you don't straighten up next year, crumpets, buddy.

他们举行了&茶党&抗议，一直在往国会寄茶包，我猜他们是想表达他们对税收和政府开支的不满，因为没有什么能比一个赠送的茶包更能动摇一个政客了：'嘿，伙计，要是你们明年再不改，我们就寄煎饼。

All the preparation I did minded me alot of my memory of heading for Singapore 7 years ago . Seven years! Time really can fly really fast when I realized it, Then I was also busy with packing, so many clothes I took with me and most of which are formal dress, ridiculous! Due to the fact I had worked in insurance company before I got the job in Star Crusies, almost all my clothes were suits for formal occasions.

想起7年前，也是夏天，我第一次走出国门，飞往我曾经梦想之地新加坡，也是准备大包小包的行李，那时好傻，带了好多衣服，因为之前在保险公司工作，衣柜里全是正装，就带去了大量的套装，到了那里几乎都没穿，最后扔了一部分，剩下的那部分一年后原封不动地背回来。
