Personal insurance premiums grew by 22 per cent in 2007, on a year-on-year basis, and total penetration is low. 2007年个人保费收入较上年同期增长22%,而总体普及率较低。
In this paper, some parameters of the optical properties of biological tissues are discussed in detail, including absorption and scattering coefficients, anisotropy factor, as well as total attenuation coefficient and effective penetration depth introduced by them. 本文比较全面而详尽的讨论了生物组织的光学特性参数,其中包括吸收系数、散射系数、各向异性因子,以及由它们导出的总衰减系数、有效透射深度等。
However, the skin factor determined by pressure buildup curve of gas well is a total skin factor which includes penetration degree skin factor, perforation density skin factor, high velocity turbulence skin factor and mud damaged skin factor. 然而,利用压力恢复曲线确定的表皮系数,是一个总表皮系数。它应包括:打开程度表皮系数、射孔密度表皮系数、高速湍流表皮系数和泥浆污染表皮系数。
But the total regularity is that the penetration is decreased, ductility is increased with modifier dose accession, and hot and low performances of modified asphalt have been improved to varying degree. 但总体规律是随着剂量的增加针入度减少,延度增大,改性沥青的高低温性能得到不同程度的改善。
The single factor prediction model only utilizes one parameter of the rock material properties, such as rock uniaxial compressive strength, Brazilian tensile strength or the total hardness, to predict the TBM penetration rate. 单因素预测模型中包括的主要岩石材料参数有岩石单轴抗压强度、抗拉强度及岩石的总硬度;
