Packaged within geminate particles, the genomes of geminiviruses are single-stranded circular DNAs that are replicated mainly by a rolling circle mechanism, characteristic to prokaryotes. Previous researches have indicated that geminiviruses can generate various DNA replication forms in bacteria, suggesting that geminiviruses possess the potential to regulate the expression of certain viral genes in prokaryotic systems.

双生病毒在植物细胞中是主要以原核生物形式的rolling circle replication方式做复制，而先前研究指出双生病毒可以在原核系统里进行复制，因此，双生病毒基因体中应具有在原核系统中亦能表现的调控机制，除了已知的基因外，是否有其他未知的基因参与这项机制仍不清楚。

Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature. Finally, we will employ the Minkowskis support function to construct a new kind of non-circular smooth constant breadth curves in order to attack some open problems on the constant width curves for example, whether there is a non-circular polynomial curve of constant width, etc.

I had a short jacket of goat-skin, the skirts coming down to about the middle of my thighs; and a pair of open-kneeed breeches of the same, the breeches were made of the skin of an old he-goat, whose hair hung down such a length on either side, that like pantaloons it reached to the middle of my legs; stockings and shoes I had none, but had made me a pair of some things, I scarce know what to call them, like buskins to flap over my legs, and lace on either side like spatter-dashes; but of a most barbarous shape, as indeed were all the rest of my clothes.

我上身穿着一件山羊皮短外衣，但衣襟遮住了一半大腿；下身穿着一条短裤，连双膝都没有盖上。短裤也是用同一张老公羊的皮做的，毛很长，几乎垂到小腿上，看上去像一条长裤。我没有鞋子和袜子，但做了一双像靴子之类东西，自己也不知道该叫什么，穿在脚上，小腿的两边再用绳子系起来，像打上了绑腿。这双靴子与我身上的其他装束一样，野蛮粗俗，实在难看。

The impedance ratio and the meander could control the frequency of the second harmonic and the baseband ratio. According to that,we analyze several kinds of stepped impeedance resonator and use them to design the dual-band bandpass filters.In the thsis , The proposed bandpass filters and dual-band bandpass filters are designed for IEEE 802.11a/b wireless communicatuon system.

Although the conservative termed secondary homothallism inherit mode and absence of wild resources, the commercial strains encompass extremely limited genetic variation, in this paper we revealed some variations of phenotypic and genorypic characteristics among the tested strains in mycelium growth rate, field performance, esterase isozyme, soluble protein and AFLP fmgerprint.

双孢蘑菇由于自身保守的次级同宗配合遗传方式以及长期野生种质资源的匮乏，造成现有栽培菌株之间相似性程度较高，尽管这样，本试验采用不同方法，从菌丝生长速度、农艺性状、蛋白质以及基因组各方面系统地反映了双孢蘑菇主要商业栽培菌株间的表型及遗传差异性，为双孢蘑菇种内杂交育种提供了科学依据。
