采用κ-ε湍流模型、标量联合的概率密度函数输运方程和层流火焰面模型相结合，模拟氢气自由扩散火焰中辐射源项湍流脉动特征。给出了主燃区内辐射源项湍流脉动的频率图。辐射源项的样本点分布集中，大约95%以上的样本落在其系综的±3倍方差以内，频谱图为单峰

Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

The parameters for blanching and green- protecting of Opuntia Milpa Alta juice were studiedusing single factor and orthogonal experiment. The results showed that 1.5 times boiling blanching for 1.5min, and the centretemperature reached 93 ℃,not only inactivated the peroxidase, but also increased thecontents of total polyphenolics and soluble solid in the Opuntia Milpa Alta juice, and a well green- pro-tecting effect could be obtained by adding 100 μg/g Zn2+, 40 μg/g Cu2+,0.075 %Vc,0.025 % citricacidin blanc...

通过单因素实验和正交实验，对米邦塔仙人掌制备绿色蔬菜汁饮料的热烫护绿工艺条件进行了研究，结果表明：采用1.5倍体积沸水热烫1.5min，中心温度达93℃，可使过氧化物酶的活力基本丧失，也可提高仙人掌汁中总酚和可溶性固形物的含量，同时在热烫护绿液中加100μg/g的Zn2+、40μg/g的Cu2+、0.075%Vc、0.025%柠檬酸，护色20min，护绿效果好。

Wheat straw powder amendment induced one times and more emissions of N 2O and CH 4 than no its application, and hence, even only from the standpoint of diminishing soil source greenhouse gases emission, applying unmatured composted organic materials with urea is an inappropriate fertilization system.

不论是N2O还是CH4的排放总量，施麦秸粉的都比未施的高出1倍和更多。因此，单从土壤源温室气体排放的角度看，将未腐熟的有机物料与尿素共施，并不是一种适宜的施肥制度。

By stretching the song to about 50 times slower than normal, one can enter a rich world of odd tones, microscopic vibrations and little glissandi not belonging to the actual melody, but being a natural part of the human voice and the Chinese tradition of singing.

随着歌曲旋律被放慢到比正常速度慢五十倍，这时就进入了一个丰富的单音世界，显微镜摆动着，小的滑音并不属于真实的旋律，却是人声和中国民族唱法组成的自然的声部。

Methods: A randomized, single blind controlled clinical design was used to accomplish the series clinical trials included 123 cases. The troop of gatifloxation injection with sodium chloride included 20 cases in gatifloxation group and 23 cases in ciprofloxation group; The troop of gatifloxation injection with glucose included 21 cases in gatifloxation group and 19 cases in levofloxacin group; The troop of gatifloxation pivoxil included 19 cases in gatifloxation group and 21 cases in ciprofloxation group. The antibacterial activity of clinical isolates were detected by scrips which contain gatifloxation(5ug/L), levofloxacin (5ug/L), ciprofloxation (5ug/L), spafloxation(5ug/L), cefotaxime(30ug/L), penicillin(10U/L) respectively. The MICs of sixkinds of antibiotics were detected by 2-fold agar dilution method. Result: The common data of patients in the two groups of 3 troops were similiar.

采用区组分层均衡随机单盲试验设计，分别完成甲磺酸加替沙星氯化钠注射液组试验药20例及对照药23例、甲磺酸加替沙星葡萄糖注射液组试验药21例及对照药19例、甲磺酸加替沙星片剂组试验药19例及对照药21例共123例感染患者的临床试验；用K-B法测定临床分离致病菌对加替沙星(5ug／L)、左氧氟沙星(5ug／L)、环丙沙星(5ug/L)、司帕沙星(5ug/L)、头孢噻肟(30ug／L)、青霉素(10U／L)纸片的敏感性，再用按美国国家实验室标准委员会(National Committee for Clinical Laboratory Standards，NCCLS)推荐的琼脂平皿对倍稀释法测定临床分离菌株对加替沙星、左氧氟沙星、环丙沙星、司帕沙星、头孢噻肟、青霉素的最低抑菌浓度(Minimum Inhibitory Concentration，MIC)以了解其体外抗菌活性。
