There are no conductions about the obvious form and the error equation of Romberg's quadrature formula in present literatures.

然而现有的文献并没有给出其显示Romberg公式，给实际应用带来了诸多不便，也没有介绍Romberg公式具体的误差等式，只给出了阶数[1][2][3]，下面给出显示Romberg公式和误差等式。1显示Romberg公式的具体形式在现有的文献中，Romberg公式是借助于误差的事后估计法或Richardson外推加速法得到的，而且有结果6364211R=C？

In the equation of state the induced dipole and quadrupole interactions between the particles are neglected.

摘 要 基于微扰理论并借助于统计缔合流体理论的基本思路，建立了氨基酸和糖水溶液密度的状态方程。

With the help of special radio telescope, the intensity of radiation can be measured in different parts of the sky.

借助于专门的射电望远镜，就可以测量天空中任何地方辐射的强度。

Benefited from the influential power of radiocast, disc won the attention of society and authority, which bought it both opportunity and disaster.

借助于广播的力量，唱片获得了前所未有的社会影响力，逐渐受到社会的瞩目，官方的关注。这既为唱片带来了机遇，也招致了厄运。

Experiments show that the fuzzy C-means clustering algorithm can distinguish gas samples of different classes, and can be used in real time detection of gas.

利用遗传算法，并借助于反向传播神经网络，对气体定性识别系统中的气体传感器进行筛选，通过评价传感器组合对反向传播网络识别单一气体结果的影响，建立了一种优化传感器阵列的方法； 6。

Based on the vector law of refection in optics, the scanning error′s academic formula is educed.

分析表明，用激光及其扫描装置建立光学基准面时，扫描误差是不可避免的，这种误差不加补偿，则最终将引入基准光学平面影响基准精度，进而降低参数的评定精度；借助于所推导的误差补偿公式，是可以补偿这种误差的，这对于建立高精度的扫描基准平面具有理论指导意义。

What is manifested in the re-shaping of village and reinstitution of village regime is state's re-admitting and respecting village's local knowledge. State, with the help of traditional resources, modern governing idea and market economy, is changing its way of being in the village arena. Having lost the strong pushing force of pan-politicization, modern knowledge and technology, as the important components of modernity, have turned to seek a non-political access to rural community; while the re-expanded village local knowledge has become an important resource to re-structure the authority and order of the new Shuang Village.

村庄的再造和村政的重建所凸现出的是在新的历史条件下国家对村庄地方性知识的重新承认与尊重，国家借助于传统资源、现代治理理念和市场经济改变着自己在村庄场域中的存在方式；作为现代性重要构成的现代知识与技术在失去了泛政治化的强力推动后，也转而寻求对于乡村社会的一种非行政化的切入路径；而重新扩张的村庄地方性知识则成为重新构造新时期双村权威与秩序的重要资源。

Through the new research methods, this thesis has made the following contributions in this field: 1. For the first time the curvature radii and relative angles of a planar continuous curve at discrete points are chosen as local parameters to represent the curve, which reflect clearly the local geometrical characteristics of the curve and are easy to be dealt with.

借助于新的研究方法，本文在这一领域作出如下贡献：（1）首次提出用曲线上离散点处曲率半径和相对转角作为局部参数表示平面连续曲线，直观地反映曲线各个局部的几何特征，且便于曲线的修改和变换，并通过机构运动分析，快速求出机构轨迹的这两个局部参数。
