ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.
其创新点为:具有能自动关闭并可靠密封的阀门结构:采用有先导阀复式结构阀瓣设计,解决反向密封结构阀门开启沉重费力的难题;设计自控排水装置,能自动排除栓体内余水;在栓体和阀体之间设计撞裂板,它既起到连接栓体和阀体的中介作用,又可在地上消火栓被撞击时率先破裂毁坏,并使露出地面的栓体不见整体脱落,有效保护各主体部件的完好无损,而此时阀门的自闭式结构可靠密封阀门阻止水源外泄,修复时只需更换损坏的撞裂板即可立即复位投入使用,使被撞后的修复工作变得十分轻松简便。

AVI may be protein matrix and it possesses neither a membrane boundary nor an internal structure,its formation is the result of the anthocyanins transported into the vacuole bind with a protein matrix. In vacuole, AVI is irregular and jelly-like in shape. In AVIs, the attachment of anthocyanins to the matrix protein is likely to be via H-bonds to a sterically restricted site. AVI is suggested to act as vacuolar anthocyanin "trap", preferentially for anthocyanidin 3, 5-diglycosides or acylted anthocyanins. The emergence of AVI can enhance color intensity and results in the "blueness" of color in the vacuole.

The tryptophan residues play important roles in DNA photoreactivation catalyzed by CPD photolyases. We have investigated the action mechanism concerning Trp in DNA photoreactivation, and obtained the results as follows: 1 We proposed a mechanism of photosensitized splitting of CPDs by Trp and Trp-containing peptides. 2 Quantum yields of splitting of the model compounds that a Trp linked covalently a CPD were obtained under 290 nm light in various solvents, these values changing with solvent, range from 0.01 to 0.5. 3 Utilizing pulse radiolysis technique, splitting processes were observed in aqueous solution of the CPDs with hydrated electron and some oxidative species (such as hydroxyl radical, bromic radical and azide radical), and obtained their rate constants. In the case of interaction between CPD and hydrated electron, splitting of the CPD anion, and pyrimidine anion transfer an electron to FAD or Rf, were observed. The process rate was slower one order more than that in photolyase. Minor, but highly mutagenic UV-light-induced lesions are (6-4) photoproducts, which are repaired by (6-4) photolyases. These enzymes, discovered in 1993, are not well characterized and their mechanism is still under investigation.
