Firstly, we discuss the characterization of eigenprojections at zero of thegeneralized Drazin invertible operator on Banach space. By using the techniqueof block operator matrices, we extend the results that the characterization of eigen-projections at zero of matrices to operators in B.

中文摘要我们首先讨论了广义Drazin可逆算子在0点的特征投影的刻画，利用算子矩阵分快的技巧将关于矩阵在0点特征投影的刻画的一些结果推广到了Banach空间上。

Bifurcations of Zero Crossings: The isotopy theorem [50], [1] shows that transversal intersections are structur-ally stable, i.e., that "transversal zero-crossings" are structurally stable: their topological properties do not change if the size of the filter is slightly changed.

零相交的叉路：同位定理[50]， [1]表示，横截交叉点结构地是槽枥，即，"横截零相交"结构地是槽枥：他们的拓扑学物产不改变，如果轻微地改变大小过滤器。

X cannot be zero if y is less than or equal to zero.

如果 y 是小于或等于0， x 不能为0。

Flying isn't human dream, material and material are absolutely contact, and stone, contain CaCO3,... By analogy, you say that all matter, they contain more than the matter, small quarks also can find this matter, if the antimatter, like lodestone, then the humanity will use it to fly in the sky, there is the hydrogen plate, sheet metal plates of hydrogen is close to zero and even, quality, less than zero, the density of titanium and not hypothesis, maybe one day will be achieved.

人类飞天并不是梦想，物质与物质间都存在着绝对的联络，人和石头有联系，都含有CaCO3，……以此类推，你可以说到的全部物质都有联系，它们都含有比夸克还小的物质，如果能找出这种物质的反物质，就像吸铁石一样，那么人类一定会利用它飞上天空，还有就是氢板，氢板是类金属板，质量接近于0甚至小于0，密度大于钛，这并不是假说，可能以后的某一天会实现的。

If a gyro is used to measure the rate of rotation around the aircraft roll axis, it will measure a non-zero value as long as the aircraft is rolling, but measure zero if the roll stops.

使用陀螺仪测量飞机机体轴向的旋转角速率时，如果飞机在旋转，测得的值为非零值，飞机不旋转时，测量的值为零。

How to measure the program zero point location on the machine Figures 11-3 and 11-4 show a setup for a vertical machining center and stress how the program zero piont measurements can be made.

如何到尺寸那计画零点位置在机器上图 11-3 和 11-4 表演一种装备为一垂直的机制中心和压迫力如何那计画零 piont 测量罐子是制造。

Takayuki Tamura and his colleagues work at the Product Development Research Laboratory of Mercian Corporation in Kanagawa, Japan. They started their exploration of what was behind the strange aftertaste by asking seven experienced wine tasters to sample red wines and white wines while eating scallops. The panellists were instructed to rate the presence of any fishy aftertaste on a scale of zero to four, with zero indicating no such aftertaste and four indicating an extremely strong one. Over the course of four sessions, they were presented with a grand total of 38 red wines, 26 white ones, 2 sherries, a dessert wine, a port and a Madeira. The drinks were offered in random order, in coded glasses.

Takayuki Tamura和他的同事在位于日本Kanagawa的Mercian公司的产品研发实验室工作，通过询问7位边吃扇贝边品尝红酒和白酒的经验丰富的品酒师，他们开始探索隐藏在奇怪的回味背后的东西，他们被要求将任何鱼腥味的回味分成0到4几个等级，0表示没有这样的回味，4表示回味相当浓，经过四个连续的时间段的试验，他们品尝了38种红酒、26种白酒、2种雪利酒、1种甜酒、1种葡萄酒和1种Madeira白葡萄酒，酒装在带有编码的杯子里，按照随机顺序提供。

Concerning value distribution theory, Q.C.Zhang got the following result:Let f be a non-constant meromorphic function in C, b is a finite non-zero complex number, if f and f" CM share 0 and IM share b, then: f ≡ f", or f =(2b)/(1-ce-2z) here c is any non-zero constant.

在值分布理论中，张庆彩得到了这样的结果：设f是复平面上的非常数亚纯函数，b是非零的有限复数，若f和f′CM分担o且IM分担b，则： f≡f′，或者 f=2b/1-ce-2z ，其中c是任意非零常数。

Its output current can be continuously adjusted from zero to two hundred milliamperes and its stability reaches 1.5×10-5. The variation of the output current is less than 1μA when its operation time is longer than 12h. The modulation of frequency and intensity of optical wave in the laser interferometry can be achieved by the modulated current (100kHz～300kHz) input, whose modulation depth is continuously adjustable from zero to one hundred milliampere.

该电路的直流稳定度高达1.5×10-5，输出电流在0～200mA内连续可调，长时间工作（12h以上）电流变化小于1μA；在直流基础上注入100kHz～300kHz的调制电流，其调制深度为0～100mA连续可调，可实现在激光干涉测量中对光波频率和光波强度的调制。
