If there is a value of chromatic aberration in each group, and a certain relationship between the positive or negative sign of chromatic aberration and the selection of glasses, the secondary spectrum of the whole lens system can be reduced to any small value.

从理论上讲，如果使每一组元产生一定量的色差，并使色差的正或负与玻璃的选择满足一定的关系，则整个透镜系统的二级光谱可减小到任意值。

Necessary and sufficient conditions of the robust positively invariant sets are established for the linear discrete-time system family specified by matrix convex polyhedron and additive interval disturbances.

对由矩阵凸多面体和加性区间扰动描述的线性时变离散系统族，得到了鲁棒正不变集的充分必要条件；对非线性系统族则得到有关充分条件。

The hybrid grid system of natural water bodies are in orthogonal body-fitted curvilinear coordinates in horizontal directions, and in Cartesians coordinate in the vertical direction.

天然水域的混合网格系统，在水平方向上是正交贴体坐标系；在垂直方向上则是笛卡尔坐标系。

Inthe horizontal plane, the orthogonal they-fitted coordinate system exactly fits the shore lines, and in the vertical direction, the blocka...

在该坐标系统中，水平面上的正交贴体坐标系与岸线精确地吻合；铅垂方向则采用笛卡尔坐标系中的堵塞技术使之与底部边界吻合。

The changes are part of a larger overall strategy that will gradually de-emphasize conventional phones in Nokia's business. It expects phones using the smartphone-grade Symbian OS to ship on just over half of its phones by 2011 with the old, limited S40 relegated to a third of its handsets. Maemo will have the smallest share but will be reserved for Nokia's most advanced devices.

这些变化显示诺基亚正计划逐步将开发重点由普通手机转移到智能手机产品方面，预计到2011年，诺基亚销售的所有手机中，使用塞班操作系统的智能手机将超过半数，而使用S40系统的手机比例将减少至1/3，而高端产品用Maemo所占的比例则仍为最少。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
