查询词典 density

If the cell density of Microcystis aeruginosa and Anabaena flos-aquae was 6×10~7~7xl0~9L~-1 and 4 × l0~7~5×l0~8 L~-1, the FDA staining rate would be more than 94% and 91%.

The analytic expression of optical rectification coefficient of this system is derived by means of density matrix approach and the iterative method.

用量子力学中密度矩阵算符理论导出了加偏置电场的双曲线量子阱中光整流系数的解析表达式。

Based on this spectrum function, the analytic reconstruction of the density image is studied.

在这一能谱函数的基础上，我们研究了康普顿散射图像的解析重建问题。

Results show that:(1) For each particle size of andalusite, variation tendency of the properties of the material is generally the same: the maximum of bulk density, compressive strength and rupture strength appears in the range of 5%-10% content of fiber, these properties of the material remarkably decrease as the fiber content exceed 10%; while at the same fiber content, the properties of the material increase with the increase of firing temperature.

结果表明：(1)对于不同粒度的原料，性能变化规律大致相同：在同一烧成温度下，体积密度、常温耐压强度、常温抗折强度在5％～10％之间出现峰值，加入量超过10％之后材料的性能明显下降；在相同的纤维含量下，随着烧成温度的提高，试样的各项性能均有所上升。

For adjusting and optimizing spark advance angle of SI engine and improving power density and fuel economy and reducing exhaust emission, an electronic control ignition system applied to GDI engine was developed in this paper.

为了对火花点火发动机的点火提前角进行调整优化，本文开发了一种适用于直喷汽油机的电控点火系统。

The ignition delay period is controlled by the fuel injection advance angle which is an important parameter. If the advance angle of injection is adjusted earlier, the density of the combustion chamber is small and its temperature is low, when the fuel is injected into the combustion chamber. So it needs long time to atomization.

喷油提前角是影响燃烧滞燃期的重要参数，喷油提前角的大的工况，燃油喷入燃烧室时缸内空气的密度小，温度低，燃油雾化所需时间长，sauter平均直径大，油滴汽化的表面积越小，所以油束雾化效果不好。
