查询词典 sampling distribution

A549 cells are more sensitive to CDDP-induced apoptosis(P.01) and less sensitive to THP andβ-Ele-induced apoptosis than A375p(P.01, P.05 respectively). Condensation and crack of nucleus and apoptotic bodies appeared in apoptotic cells of A549 and A375p cell lines in all treated groups and necrocytosis were to be seen in some groups. Fluorescence imaging experiments demonstrated that accumulation of iASPP in cytoplasm but little distribution in nucleus in all groups. untreated groups in two cell lines presented a bright-green colour,followed by CDDP-treated groups,and THP-treated groups is the darkest one in all groups.

免疫荧光显示，未加药物处理的A549和A375p细胞胞质染色均匀呈亮绿色，核区较暗；CDDP及β-Ele处理组细胞为暗绿色，其中可见皱缩的凋亡细胞；THP处理的细胞胞质荧光弱呈灰绿色，由于THP嵌入DNA自发红色荧光与二抗的绿色荧光中和，胞核被染成桔红色，结果提示药物处理后A549和A375p细胞中iASPP的表达有不同程度的下降。

Knitting oil stable at high and low temperature was prepared by emulsification between 20# white oil as base oil and O-3 and O-6 of narrow molecular weight distribution, Span-80, Tween-80, PK, and barium petroleum sulfonate as emulsifier. Condensation point, residue analysis, emulsifying properties, permeability, antistatic performance and application effect were used to characterize knitting oil.

On the basis of the data obtained from the field observations and wind-tunnel modelling, the calculations and comparisons on probability distribution and density, linear correlation analysis of time series, conditional probability density and so on of wind speeds and directions between various sites are made with the aid of statistical analysis of time series, and changes of these variables with height and representativeness of observation period of meteorological data are also discussed.

本文以现场气象观测和风洞模拟实验数据为基础，通过对时间序列进行的统计分析，计算和比较了各个厂址风速、风向的概率分布、概率密度、时间序列线性相关分析、条件概率密度等，还对它们随高度的变化情况、观测时段代表性等问题进行了讨论。

This paper uses mixture density networks to forecast the time-varying conditional density values of financial time series, and puts forth a new numerical algorithm to calculate Expected Shortfall. The application in Hong Kong Hangseng index approves that Value-at-Risk at high probability levels is accurate, and that it also has good forecasting ability in fluctuation. MDNs can effectively describe the empirical distribution of returns and the volatility mechanism, and is a new model for measuring financial market risk.
