When the adjacent exons 50 and 51 are joined, the extra one and two nucleotides form an additional full codon.

当相邻的外显子50和51个属于加入，额外的1和2个核苷酸组成一个额外的充分密码子。

This kind of configuration suits the multi-nucleotide chain's purine pyrimidine alternate area. in 1989, the American scientists with scanning tunnel electron microscope law visual observation double helix DNA double helix DNA ︰ in 1952, Austrian lineage US biology chemist Zha Qiefu (E.chargaff,1905-) have determined in DNA 4 kind of basic group content, the discovery gland fat ling and thymine quantity are equal, the bird fat ling and cytosine quantity is equal.

这种构型适合多核苷酸链的嘌呤嘧啶交替区。1989年，美国科学家用扫描隧道电镜法直接观察到双螺旋DNA 双螺旋DNA︰1952年，奥地利裔美国生物化学家查伽夫（E.chargaff，1905—）测定了DNA中4种碱基的含量，发现其中腺膘呤与胸腺嘧啶的数量相等，鸟膘呤与胞嘧啶的数量相等。

The flux and rejections increased with increase of velocity of feed. On the other hand, they decreased when the concentration of feed increased. The rejection for inorganic p decreased when increase of PH of feed.

膜对核苷酸和磷酸盐的截留率及膜的渗透通量随操作压力和进料流速的提高而上升，随进料浓度的上升而下降。

The nucleotides sequence and deduced amino acid sequence of these cDNA figments mentioned above were divided into two fractions. One is carbon part of L gene , the other is 5 terminal,and they were compared with other rabies-related virus strains published in NCBI previously.The result show that the homology of nucleotide sequence and amino acid sequence of carbon part in L gene among these two rabies virus strains is 91.3% and 95.8%, and these two strains belong to type of gene I.

本实验以吉林鹿源DRV8202株及河南鼠源野毒株MRV的L基因的C端为主要研究内容，用RT-PCR和3'-RACE方法对其进行了克隆和测序，将所测得的核苷酸序列和推导的氨基酸序列分成两个部分，一是L基因C端序列，另一个是L基因5'端的非编码区，并与NCBI上公开发表的狂犬病毒其它毒株的相应片段进行分析比较。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
