多变化的

Gasoline retailers and refiners like high-test because it's more profitable than regular-grade gas is. The retailer paid about 8 cents more for the premium you pay 20 cents more for — though that margin can swing wildly. Refiners make a few cents a gallon more on premium than on regular when they sell to wholesale distributors.

汽油销售商和炼油厂喜欢高标号因为比普通的利润高，销售商多花8分钱买高级油你多花2毛，不过这个差别变化很大，把油卖给批发商时炼油厂每加仑高级油比普通的多挣几分钱。

The analysis on the test result shows that the temperature distribution in CFST members caused by solar radiation is nonlinear,and the nonlinear character is most evident when center point of concrete gets its lowest temperature. The temperature of the center point is affected by various directions, especially the strong potential. In the side exposed to the sun in the afternoon, apart from the center point, temperature varies laggardly when the point of concrete in the same series is more close to the center. But in the side not exposed to the sun in the afternoon, temperature varies laggardly when the point of concrete in the same series is more close to the center.

结果表明，日照作用下截面的温度场为非均匀场，混凝土中心的温度达到最小值时，截面温度场的非线性特性最明显，圆心点的温度受各个方向温度的共同作用，更多地受到强势方向的影响；下午时处在向阳面的各系列，同一系列上混凝土各点温度变化随直径缩小趋缓，越靠近圆心，温度变化越缓和，对外部环境的影响呈滞后现象越明显；而在下午时处在背阴面的各系列除圆心点外，同一系列上越靠近圆心的混凝土测点，温度变化越缓和。

Hardware support for Multithreading is more visible to software, thus requiring more changes to both application programs and operating systems than Multiprocessing.

硬件支持多线程是可见的软件，因此需要更多的变化都应用程序和操作系统比多处理。

Liver function and pathological changes of hepatic tissue were examined.

采用ANIT灌胃制备大鼠急性肝内胆汁淤积病理模型，共32只大鼠，设正常组、正常＋大黄素组、模型组和模型＋大黄素组，观察各组实验动物肝功能各项生化指标和肝组织病理学改变，并采用实时荧光定量RT-PCR检测肝细胞膜转运蛋白基因多药耐药蛋白1a（mdr1a）、多药耐药蛋白1b（mdr1b）和多药耐药蛋白2（mdr2）mRNA水平的表达，Western blot方法检测肝脏P-糖蛋白的变化。

However, the cell wall cultured at high concentration of Cu2+(10～200 mg/L) was clearly thickened and became multiple layers, and the pigment decreased and the pyrenoid became one or disappeared. Low concentration of Cu2+(0.01 mg/L, 0.1 mg/L) did not affect the growth of Chlorococcum sp., but the growth became slow and even negative beyond the concentration of 0.1 mg/L.

与对照BG11培养的绿球藻比较，0.01～1 mg/L Cu2+浓度下培养的绿球藻，细胞壁无明显增厚，色素没有多大变化，但蛋白核由一个变为多个；而在高浓度(10～200 mg/L Cu2+)下，细胞壁明显增厚为多层，色素减少，蛋白核减少并回复到1个或消失。

Data analysis shows that the total amount of PAHs in the sediments of north Taihu Lake is obviously higher than that at the central and south Taihu Lake, and that there is a little difference between the contents of PAHs of high molecular weight and low molecular weight, while the ratio of PAHs varies in different sections of the lake. Through the statistical analysis of the ratio of fluoranthene to pyrene, it is concluded that PAHs mainly come from oil burning with part of them from coal and wood burning.

分析结果表明，太湖北部的多环芳烃总量明显高于中部和南部，低分子量多环芳烃与高分子量多环芳烃的含量差别不大，但在地域上比例有所变化；根据荧蒽/芘的比值统计，多环芳烃主要来源于石油燃烧，部分为煤和木材的燃烧形成。

比较多种核型多角体病毒的多角体膜蛋白和多角体蛋白的氨基酸序列发现，这两种多角体结构蛋白的同源性具有相似的变化趋势。

Results High purine diet is the main diet habit of the gout people, young and middle aged male prefer to alcohol. The cause of gout in young and middle aged male is drinking mass of alcohol and strenuous exercise,while old aged male is catching cold,changing weather and the use of diuretic. Young and middle aged male will first outbreak at the first metatarsophalangeal joint,involve in single joint,while old aged male at the knee and ankle,involve in two to three joints. Old aged male always go with hypertension, coronary heart disease and diabetes,the rate is significantly higher than that in young and middle aged male(P＜0.05), while the rale of hyperlipemia is similar in two groups.

结果 两组患者均嗜好高嘌呤饮食，中青年男性饮酒明显多于老年男性患者；发病诱因方面中青年男性主要有剧烈运动、大量饮酒，而老年男性主要是感冒、天气变化及使用利尿剂；中青年男性痛风首发第一跖趾关节为多，多数累及单关节，而老年男性则以膝、踝等大关节为多，累及2～3个关节；老年男性合并高血压、冠心病、糖尿病的概率比中青年男性多，两者差异有统计学意义(P＜0.05)，但两者合并高脂血症的概率则无明显差异。

In 1956 Gilbert Plass was heir to a century of work that identified variations in the trace amounts of carbon dioxide in the atmosphere as a possible cause of ice ages and interglacial periods.

1956年的吉尔伯特·普拉斯深受一个世纪以来科学工作的影响，当时认为大气中微量二氧化碳的变化是引起冰川期和间冰期的因素之一。1861年约翰·丁达尔写道，大气中任何有放射活性的物质（水蒸气、二氧化碳、臭氧或烃类）数量发生微小的变化，都可能引起&地质研究所发现的各种气候变化……它们是真正的原因，只是有多大范围的影响还存在疑问。&

As a new technology, high-speed machining has been constantly explored and has brought revolutionary change to traditional metal-cutting theory.

本文通过进行多因素正交实验，得到了曲面高速铣削表面粗糙度在多个因素共同作用下的变化规律，并建立了多因素共同作用下曲面高速铣削表面粗糙度的预测模型。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
