数一数

Firstly, we prove that if we select nodes properly, and let the distance between these nodes sufficiently small, cubic polynomial spline can approximate a continuously differentiable function, which with continuous derivatives of second order and discontinuity of the first kind in the derivatives of fourth order, to any desirable accuracy. This result lays a theoretical foundation for representing trajectories by splines and double orthogonal basis.

一是证明了适当选取节点并使节点距充分小时，三次多项式样条可以逼近具有二次连续导数的分段四次连续可微函数到足够的精度，这一结论为用样条和双正交基表示弹道打下了理论基础。

Flowers solitary or in a corymb, rarely in a compound corymb or a panicle; bracts solitary, several, or absent.

很少，花单生或在一伞房花序复合的在一或者圆锥花序；苞片单生，数个，或无。

I mean, count it down like so, starting with your thumb first.

我是说这样，从拇指开始一根一根往下数

We will call the construction a crossed product. The results about the sufficient and necessary conditions for A#H, the smash product, to have finite global homological dimension have been discussed in ~WYZ. which will be extended to crossed prodcut A#a.

关于smash积有有限整体同调维数的充分必要条件这一结果在中已有了一定的讨论，本文主要是将关于smash积的这一结果推广到crossed积。

Two approaches,one called CG method in this paper which based spatial cubic partitioning where the axis-aligned bounding box of the data points is partitioned by a cubical grid,and another based on tree structure such as kd tree are known for the problem.

目前主要有2种方法，一种是基于立方体分割形成的三维立方体体素索引数组的体素栅格（CG方法，另一种方法是基于树索引结构的方法如kd-Tree等。

It would be an easy map if that were all, but there is also first day at school, religion, fathers, the round pond, needle-work, murders, hangings, verbs that take the dative, chocolate pudding day, getting into braces, say ninety-nine, three-pence for pulling out your tooth yourself, and so on, and either these are part of the island or they are another map showing through, and it is all rather confusing, especially as nothing will stand still.

若是只有这些，这张地图倒也不难画。但是还有呢，第一天上学校，宗教，父亲，圆水池，针线活，谋杀案，绞刑，与格动词，吃巧克力布丁的日子，穿背带裤，数到九十九，自己拔牙奖给三便士，等等。这些若不是岛上的一部分，那就是画在另一张画上的了；总之，全都是杂乱无章的。尤其是因为，没有一件东西是静止不动的。

The decay of ~(99m)Tc source was used to verify experimentally that in the measurement of the number of atoms of a radioactive isotope in a sample at time t_0, the error introduced through the inaccuracy of its decay constant can be reduced to a much smaller value by the careful selection of the time of measurement or measurements of its radioactivity at around one life time (1/λ) after t_0 and doing the calculation.

本文用~(99m)Tc源的衰变实验证明了：在测量一个样品中在t_0时的一种放射性同位素的原子数时只需精心选择一次或多次测量其放射性的时刻在t_0后约该同位素的一个寿期(1/λ)，并进行计算，则由它的衰变常数或其半衰期(T1/2)的不准确性而引进的误差可以被降低到较小值。

This one brand-new the strategy makes the network made tool of a kind of politics revolutionarily, help Aobama obtain " small dedicator " people the contribution on the net, the contribution that is less than 200 dollars each is tired add up amount exceeds 2 million dollar, be in at the same time of the the Democratic Party return in primary election within the party aroused quickly 10 thousand tens of proponents.

这一全新战略使网络革命性地成为了一种政治工具，帮助奥巴马获得"小捐赠者"们的网上捐款，每人不到200美元的捐款累加起来总额超过200万美元，同时在民主党的党内初选中还迅速动员了数十万名支持者。

ADAMS. According to a function with STEP5 has features of continuous first and second derivative,the higher degree of approximation,etc.,we test and verify feasibility of fore-and-aft movement and turning gait of the robot. Thus a solution of the Snake-like robot motion under the ADAM...

ADAMS软件对蛇形机器人进行了从样机模型建立到运动学仿真与分析等一系列研究；并根据STEP5函数具有一阶与二阶导数连续、较高的逼近程度等特性验证了蛇形机器人前后移动和左右转弯步态可行性；找到了一种在ADAMS环境下求解机器人运动的方法，简化了理论计算，提高了设计效率。

Farther down, before one of the cottages, a lady in black was walking demurely up and down, telling her beads.

更远处，一座房子的前面，一位黑衣女士一边数着捻珠一边若有所思地来回走动。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
