Here Marx explicitly links the development of science to the development of material production.

这里，马克思明确地将科学的发展和物质生产的发展联系了起来。

In order to solve the problem,We proposed a simple formula for computing paraxial travel time of single-way wave operator. The formula is based on the forward and inverse transform between time-space domain to frequency-wavenumber domain and from vector field to exponential manifold. The travel time are expressed as polynomials of the horizontal offset between the two points, and the single-square-root operator in frequency-wavenumber domain are expressed as polynomials of wavenumber. Coefficients of travel time polynomials and that of single-square-root operator are related each other and calculated by Lie algebraic integrand, exponential map and the saddle-point method.

针对此，基于时间空间域到频率波数域和向量场到指数流形上的正反变换，提出了计算单程波算子旁轴走时的简便公式，将走时表示成空间变量(地面点到地下相点的水平距离)的多项式，将频率波数域单平方根算子表示成波数的多项式，运用Lie代数积分、指数映射和鞍点法将走时多项式的系数与单平方根算子的系数联系起来，运用单平方根算子的系数计算走时多项式的系数。

In other words, they need you and if they can't get in touch with you, their helplessness increases exponentially.

换句话说，他们需要你，如果当他们联系不上你的时候，他们的无助就会成倍地上升。

The extra-atmospheric object has not isolated the existence nearly, always with the periphery object relates inalienablly in together, and makes the mass motion together.

宇宙物体几乎没有孤立存在，总是跟周围物体不可分割地联系在一起，并一起作整体运动。

You may read the person's name repeatedly to help you associate his or her face with the visiting card .

你可以反复地看一看这人的名字，这有助于你把这人的面孔和名片联系起来。

Meanwhile as a kind of embedded real-time system, the system centers on DSP which is in charge of getting the position of the facula quickly and making the system work in line.

为了将图像传感器与DSP有机地联系起来，该系统采用CPLD作为两者的接口电路。

Based on toxicity mechanism, a QSAR model was established and used to explain the toxicity of organic chemicals to fathead minnow and Photobacterium phosphoreum, which showed good relationships with wide range of organic compounds.

根据毒性机理，从理论上推导出有机物的定量结构—活性方程，并用来解释有机物对呆鲦鱼和发光菌的毒性，成功地阐述了有机物对水生生物的毒性机制，区分了有机物对不同生物的毒性的联系和区别，为有机物生物活性预测提供了新的思路。

Such faultfinding could lead quite naturally to the belief associated with cynics of today that selfishness determines human behavior.

这种指摘很自然地得出与现在的犬儒主义相联系的信仰，认为自私自利决定人类行为
