Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

SARS-CoV属于巢状病毒目、冠状病毒科，为单正链RNA病毒，基因组全长约29.7kb，已知编码11种蛋白，其中包括4种结构蛋白，分别是刺突蛋白、包膜蛋白、小包膜蛋白和核蛋白或核壳体蛋白。S蛋白三聚体形成突起，伸出包膜表面。S蛋白是病毒的主要表面抗原成分，具有受体结合和膜融合活性，在组织嗜性、细胞融合和毒力等方面起重要作用。N蛋白与基因组RNA结合形成核衣壳。M蛋白和E蛋白是包膜形成所必需的成分。

Any of several plants of the genus Freesia valued for their one-sided clusters of usually fragrant yellow or white or pink tubular flowers.

A topdown design of an 8bit RISC MCU is presented, in order to overcome the limitation of MCS51 microcontroller The core is based on Harvard architecture with 16bit instruction length and 8bit data length The performance of the MCU has been greatly improved by introducing singleclockcycle instructions, setting multiple highspeed working registers, replacing microprogram with direct logic block, etc FPGA verification and computer simulation show that its maximum clock frequency and instruction e...

在对传统的MCS51系列单片微控制器的局限性进行分析的基础上，设计了一种基于增强8位RISC构架的微控制器内核。该MCU核采用哈佛结构、16位指令字长和8位数据字长，通过设计单周期指令、在内部设置多个快速寄存器及采用硬布线逻辑代替微程序控制的方法，加快了微处理器的速度，提高了指令的执行效率。计算机仿真验证和FPGA仿真验证的结果表明，该MCU的最高时钟频率和指令执行效率等指标均优于MCS51的5倍以上。

In a whole, the genetic diversity of clonal plants is much higher than that had been expected before. Although the genetic diversity is lower than their sexual congener, widely genetic monomorphism has been rarely found.

总体而言，克隆植物拥有比早期推测大得多的遗传变异，虽然克隆种与其近缘有性繁殖种相比，遗传多样性较低，但广泛的遗传单态性却很罕见。
