In ground tests of hypersonic scramjet, the highenthalpy airstream produced by burning hydrocarbon fuels often contains contaminants of water vapor and carbon dioxide. The contaminants may change the ignition characteristics of fuels between ground tests and real flights. In order to properly assess the influence of the contaminants on ignition characteristics of hydrocarbon fuels, the effect of water vapor and carbon dioxide on the ignition delay times of China RP-3 kerosene was studied behind reflected shock waves in a preheated shock tube. Experiments were conducted over a wider temperature range of 800-1 500 K, at a pressure of 0.3 MPa, equivalence ratios of 0.5 and 1, and oxygen concentration of 20%. Ignition delay times were determined from the onset of the excited radical OH emission together with the pressure profile. Ignition delay times were measured for four cases：（1） clean gas, （2） gas vitiated with 10% and 20% water vapor in mole, （3） gas vitiated with 10% carbon dioxide in mole, and （4） gas vitiated with 10% water vapor and 10% carbon dioxide, 20% water vapor and 10% carbon dioxide in mole. The results show that carbon dioxide produces an inhibiting effect at temperatures below 1 300 K when Ф = 0.5, whereas water vapor appears to accelerate the ignition process below a critical temperature of about 1 000 K when Ф = 0.5. When both water vapor and carbon dioxide exist together, a minor inhibiting effect is observed at Ф = 0.5, while no effect is found at Ф = 1.0. The results are also discussed preliminary by considering both the combustion reaction mechanism and the thermophysics properties of the fuel mixtures. The current measurements demonstrate vitiation effects of water vapor and carbon dioxide on the autoignition characteristics of China RP-3 kerosene at air-like O2 concentration. It is important to account for such effects when data are extrapolated from ground testing to real flight conditions.

在对江苏省四大主产棉区８２个样点７２７块田地共５７．５ｈｍ２棉田杂草群落及草害进行７级目测法调查采集数据后，对其进行主成分分析（ＰＣＡ），并赋以生态学意义的解释。研究表明，江苏省棉田杂草的发生和分布与轮作种植制度和地理区域性密切相关，其中轮作制度导致的田间水分的巨大差异是决定杂草群落结构特征的最深刻的原因，导致全省水旱轮作棉田的杂草群落有趋同性。而地理区域性构成的土壤、气候等生态因子的差异的显著影响表现在对旱地棉田的杂草群落上。数量分析的结果，可将全部样点分成４个组，即１个水旱轮作组和３个旱地组（淮北棉区、沿海棉区和沿江棉区旱地组），每组都对应着相应的优势杂草种。其中稗、马唐、鳢肠和千金子是水旱轮作组的优势杂草；淮北棉区旱地组的优势种为牛筋草，马唐和马齿苋，马唐、铁苋菜和刺儿菜为沿海棉区旱地组的优势杂草，沿江棉区旱地组的是马唐、狗尾草和铁苋菜。根据杂草群落发生的特点，提出了相应的杂草防除策略。

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.
