BRENDA EKWURZEL: When we look worldwide, the percentage of Category 4 and 5 hurricanes or typhoons or cyclones, depending on the ocean basin they're in, has almost doubled in the past 30 years -- where we see a precipitous rise in ocean temperatures, which is directly related to the heat trapping gases that we've accumulated in the atmosphere at unprecedented levels.

布伦达。伊库泽：我们所看到的是：放眼全球，依靠海洋盆地而形成的4、5级飓风、台风和气旋的百分比在过去的30年里翻了一番。海洋温度陡然上升，这与吸收热量的气体有关。这些气体以前所未有的水平在大气中累积。

The results indicate that with the increase of target current,the metal volume fraction and the radius of the metal particles of Cr-Cr2O3 cermet films increases,and the metal particles become oblate spheroids.

结果表明：随着靶电流的增加，膜层中金属微粒体积百分比增加，金属微粒的平均半径随之增加，且金属微粒逐渐趋于扁圆形，理论计算结果与实验结果吻合较好。

To identify the strain, the 16S rDNA sequence was compared with type strains of the same genus. The result can be abtained according to the homology.9 strains of Lactic acid cocci were isolated from milk and silages.

将含有阳性重组子的菌体进行测序，所得结果分别与Genbank上发表的同属的代表菌株的16S rDNA序列比较，得到相似性百分比，则可判定菌株的归属。

According to the UPV of the SSD condition concrete cylinders, the UPV reduction can reach 7.5% under oven-dry condition, and reach 4.5% under room-dry condition. It is also found that the UPV reduction decreases with decreasing the water-cement ratio of concrete.

圆柱试体(Φ10×20 cm)含水量试验结果显示含水量的改变确实对UPV有所影响，相对於试体面乾内饱和状态，在烘乾状态下之UPV折减达7.5%，而於自然曝晒状态可达4.5%，且随著水灰比的降低此折减百分比亦随之降低。

11 guinea pigs which were successfully induced myopias were extracted eyeballs, and the scleras near posterior poles were observed by immunohistochemistry methods. The positive rates of TGF-β〓 and bFGF in scleral fibroblast cytoplasma and the area percentageratio of positive cells were calculated and contrasted to controlled eyes.

将透镜诱导近视成功的11只豚鼠处死，摘除眼球，取后极部巩膜分别进行TGF-β〓和bFGF的免疫组织化学染色，观察它们在巩膜组织成纤维细胞胞浆中中表达的阳性率和阳性细胞所占面积的百分比，并与对照眼进行比较。

11 guinea pigs which were successfully induced myopias were extracted eyeballs, and the scleras near posterior poles were observed by immunohistochemistry methods. The positive rates of MMP-2 and TIMP-2 in scleral fibroblast cytoplasma and the area percentageratio of positive cells were calculated and contrasted to controlled eyes.

In the SMC of the normal rabbits, myofilaments and macula densa were abundant, few mitochondrla and endoplasmic reticulums were found around the nuclear, and the SMC was in the contractive stage. In the SMC of the model rabbits, few myofilaments and macula densa were found, rough surfaced endoplasmic reticulums and mitochondria were abundant, some phagocytosed much lipid and became foam cells, the SMC was in the synthetic stage.

实验12周，高脂组家兔主动脉斑块面积百分比为47.69±12.84％，内膜斑块厚度为0.68±0.08mm，内膜斑块横断面积与中膜面积比值为1.28±0.35；内膜脂质斑块弥漫且较厚，有大量的泡沫细胞堆积，可达8～10层，管腔直径变小，内膜不光滑；泡沫细胞内富含脂滴，呈椭圆形气球样，有的斑块中可见显著的平滑肌细胞增生及大量的弹力纤维形成。
