The control chart based on the geometric distribution(g-type chart )has been shown to be competitive with p or np chart for monitoring the proportion,especially for applications in high quality manufacturing environments.

在质量控制过程中，对于检测不合格率p的变化，特别是p较小时，基于几何分布的控制图( g-type chart)比基于二项分布的控制图(p-chart或np-chart)能更有效地检测并报警。

The control chart based on the geometric distribution(g-type chart) has shown to be competitive with p or np chart for monitoring the proportion especially for application in high quality manufacturing environments. However when the cases with LCL=0 occur, plotting values beneath the LCL is impossible given the non-negative nature of units, such type of lower control limits no ability to detect rate increase.

但是由于几何控制图的自然下限的问题，在其使用过程中若控制下限LCL＜0，则取其自然下限为0，这使得几何控制图在此情况下对于检测不合格品率p的增加是几乎不起任何作用，而此问题也是实际中我们最需要检测并作判断的问题。

In order to cover the shortage of the current antenna for high power microwave weapon, the idea of a magnetized plasma channel used as antenna for radiating electromagnetic pulse is proposed. The normal modes of Magnetized Plasma Channel Antenna in lossy gas are analyzed. The concrete realization method of MPCA is simply described. The geometric-model of MPCA is created based on the operating principle of the antenna.

Seen from the outside, the design is simple and neat. There are no decorative lines or complicated geometric patterns. The first thing I did after I got in was to sit down. The French window gave me a very good view of the scene outside. It was then that I realized that Ando's design wasn't as simple as I had expected. The shallow pond is more than a decoration. The surface of the water rippled with the breeze. I was so touched at that moment. Heart-moving architecture has to combine the buildings themselves and the exterior environment.

文学馆从外头看，简单俐落，没有花俏的线条和热闹的几何图形，等我走进馆内，第一件事就是坐下来休息，我从休憩区巨大的落地窗望外看，发现安藤并没有我刚才想的那麼单纯，原来外头浅浅的水池不只是装饰，随著微风，水面形成美丽自然的波动，当下的我非常感动，建筑物本身要和外在结合才厉害啊！

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
