Does anyone know what mathematical law or problem stops you from getting a indefinite integral for x^x or e^.

有没有人知道从x^x或者e^中得出不定积分的数学法则或解题步骤是什么？

Effects: Inserts the contents of x before position, in the same order as they were in x .

效果：在 position 之上插入 x 的内容，顺序与 x 中的一样。

The integral steering vector of coherently distributed source is deduced to be a Schur-Hadamard product comprising the steering vector of the point source and a real vector. And then a second statistics is proposed for the data collected at subarray X, the rotational invariance matrices can be estimated based on propagator method.

该算法通过将积分形式的相干分布式信源方向向量化简为点信源方向向量与实向量的Schur-Hadamard积，对子阵X接收的数据构造二阶统计量；利用传播因子最小二乘估计子阵X与Z，X与W之间的旋转不变矩阵。

According to the X-ray dose intensity, the parameters of the current detect circuit can be flexibly changed, so it can detect different energy levels X-ray.

这种采集方法可根据X射线的剂量强度，灵活的改变电流检测电路的参数，因此适用于不同能量级的X射线的采集。

When converting a CAM motion (X,Y,Z tool tip part position and I,J,K tool axis vector) to the NC tape (e.g.: X,Y,Z machine linear axes position and A,B rotary heads) the application of inverse kinematics makes the output curve completely different from one generated by the CAM system.

当将一个凸轮运动（X、 Y，Z 工具顶端部份位置和我、 J，K 工具轴矢量）转换成收据控制以带子绑起（举例来说： X 、 Y ， Z 机器线性轴位置和 A，B 旋转的头）倒转运动学的申请的时候让输出曲线完全不同一被凸轮系统产生。

Comparing with water, the optimal heat transfer enhancement is achieved near the critical micelle concentrations of surfactants. The degree of heat transfer enhancement is different with different surfactants and is influenced by solubility characteristic, ionic nature and chemical structure of surfactants. Boiling in surfactant solutions, when compared with that in water, is observed to be more vigorous with smaller-sized, more regularly shaped and faster departure frequency bubbles, but the surfactant solutions of Triton X-100 and Triton X-114 become cloudy for the cloud point of surfactants.

和水相比，表面活性剂强化池内核态沸腾换热的最佳浓度为临界胶束浓度；不同种类表面活性剂强化换热程度不同，它们与表面活性剂的溶解特性、离子类型和化学结构有关；溶液沸腾时，沸腾汽泡的脱离直径变小，脱离频率变快和更不易聚集，但非离子表面活性Triton X-100和Triton X-114由于存在浊点其沸腾溶液变浑浊。

Three counter-examples of topological space are proposed in this study: There are two metric spaces, X and Y, in which and are isometric, whileand are not isometric; Non-metric tight regular space is a counter-example of the separation of topological space; No non-zero continuous linear functionals of the linear topological space is a counter-example of linear topological space.

这里给出三个反例，存在两个度量空间X与Y，使X^2与Y^2等距而X与Y并不等距是拓扑空间中的反例；存在不可度量化的紧的完全正规空间是拓扑空间分离性的反例；不存在非零连续线性泛函的线性拓扑空间是线性拓扑空间的反例。

So your math will be: kilowatts x kilowatt-hour price x hours = cost per week.

这样的花，你计算的公式就是瓦特数X瓦特数－小时单价X小时数＝每个星期的花费。

All production prototype X-60s got a good thrashing over the past weekend, with Brian Kinwald seen at Competition Hobbies, Paul Sinclair at Whitehouse Raceway near Nashville, Tenn, and Alex Krieg at S.R.S. in Scottsdale, Ariz. All four U.K. drivers were trucking at various venues over the weekend, and Alexander Valente ran his X-60 for almost an hour at his home track in France.

所有生产原型的X六十年代取得了不错的痛击，在过去的周末，与布赖恩Kinwald出现在竞争爱好，保罗辛克莱在白宫附近的沟道纳什维尔，田纳西州，和Alex在卫星遥感战争在亚利桑那州所有四个英国卡车司机在各种场地上周末，和亚历山大瓦伦特跑的X - 60的将近一个小时跟踪他的家在法国。

Crystal structure was determined by powder X-ray Diffraction and lattice parameters as a function of Sr-concentration x were obtained by using Rietveld method.

在80K-300K温度范围的直流电阻率测量表明，材料的电性质在x=0.2和0.3之间展示了从半导体到金属的相变。x=0.2样品已接近绝缘体-金属相变的边缘。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
