    • A fuel control method for a gas turbine with a combustor being formed of at least two groups of a pluralities of main nozzles for supplying fuel, and that supplies fuel from the main nozzles of all groups upon ignition of the combustor (S1), and supplies fuel from three main nozzles of a group A during subsequent acceleration of the gas turbine (S3). Because fuel is injected from a small number of the main nozzles during acceleration, the fuel flow rate per one main nozzle is increased, thereby increasing the fuel-air ratio (fuel flow rate/air flow rate) in a combustion region and improving the combustion characteristics. Accordingly, the generation of carbon monoxide and unburned hydrocarbon is reduced, whereby no bypass valve is required and manufacturing costs are reduced. Because fuel is supplied from the main nozzles of all groups and burned in the entire area of the combustor upon ignition, it is possible to easily propagate a flame to all the other adjacent main nozzle groups, thereby improving the ignition characteristics of the whole gas turbine.
    • 一种用于具有燃烧器的燃气轮机的燃料控制方法,所述燃气轮机由至少两组用于供应燃料的主喷嘴组成,并且在燃烧器(S1)点火时从所有组的主喷嘴供应燃料,并且供应 在燃气轮机的后续加速期间来自组A的三个主喷嘴的燃料(S3)。 由于在加速期间从少量主喷嘴喷射燃料,所以每个主喷嘴的燃料流量增加,从而提高燃烧区域的燃料空气比(燃料流量/空气流量),提高燃烧 特点 因此,一氧化碳和未燃碳氢化合物的产生减少,由此不需要旁通阀并且降低制造成本。 因为燃料从所有组的主喷嘴供应并且在点火时在燃烧器的整个区域燃烧,所以可以容易地将火焰传播到所有其他相邻的主喷嘴组,从而提高整个燃气轮机的点火特性 。

    • A multi-processor system includes a main storage and buffer storages of multi-layered hierarchy, which share the main storage. A plurality of storage controllers, each of which contains a first buffer storage, are connected with the main storage and at least one processor containing a second buffer storage is connected with each of said storage controllers. The directory of the first buffer storage contains an exclusive bit indicating whether the data existing in the first buffer storage are only one copy from the main storage or not and thus reduces the repetition of requests for the data coincidence control between different storage controllers. Each of said storage controllers contains a directory having the same content as that of the directory of the second buffer storage of the associated processor and effects the data coincidence control between different processors for store request produced in the processors.
    • 多处理器系统包括共享主存储器的多层次的主存储和缓冲存储器。 每个包含第一缓冲存储器的多个存储控制器与主存储器连接,并且包含第二缓冲存储器的至少一个处理器与每个所述存储控制器连接。 第一缓冲存储器的目录包含指示存在于第一缓冲存储器中的数据是否只有来自主存储器的一个副本的排他位,从而减少了对不同存储控制器之间的数据一致性控制的请求的重复。 每个所述存储控制器包含具有与相关处理器的第二缓冲存储器的目录相同内容的目录,并且对处理器中产生的存储请求执行不同处理器之间的数据一致性控制。
