结合强度

In this paper , a series of surveys on road condition , pavement-performance and destroy reason are analyzed , soil property , hydrologic regime are combined , modulus of resilience are confirmed on heavy compaction test , foundation classification in area of Qinhuangdao is divided into 3 grades and highway is divided into 3 districts according to the principle that different soil grades produce the same effect on thickness of base course or bottom course , Classification of traffic is divided into 4 grades after observation materials of traffic volumes are collected extensively , traffic characters and parameters are analyzed .

本课题在对现有路面结构状况和使用状况进行调查，并对路面使用性能和破坏原因进行分析的基础上，结合秦皇岛地区的土质、水文条件，确定重型击实标准条件下土基回弹模量值，依据不同等级土基对路面基层或底基层的厚度产生大致相同效应的原则，将秦皇岛地区地基强度等级划分为三级并将本地区公路分成三个区。

To avoid the shortcoming of magnification change with wavelength, which will cause the spectral image pixel registration error and provide inaccurate relative spectral signal strength in the classical diffractive optic imaging spectrometer, a novel hybrid refraction/diffraction telecentric optical system combining a diffractive lens with an achromatic lens system is presented, and the working principle is then established.

为了克服在传统衍射光学成像光谱仪中，衍射透镜的焦距随波长变化引起系统放大率随波长变化，从而导致光谱图像的像元配准误差，得到并不精确的相对光谱信号强度，提出了将衍射透镜与消色差透镜系统相结合的新型折/衍混合、二组元复合远心成像光学系统的技术方案，具体分析推导了该系统的成像理论。
