The Defenders of Wildlife, a wolfish outfit, says coyotes kill 20 times more cattle than wolves do. It also says that wolves are responsible, in a typical year, for less than 2.5% of sheep deaths.

灰狼保护组织"野生动植物保护者"称，土狼能杀死比灰狼多20倍的家畜；而且，在一个典型年份内，灰狼导致的绵羊死亡只占总死亡数的2.5%还少。

The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time.

粒径越大，炉床温度越高，燃烧时间越长，破碎越剧烈；亮煤与灰煤在燃烧中均发生了二次破碎，其中亮煤的二次破碎更剧烈；燃烧后期，亮煤的颗粒破碎比灰煤更快；由于破碎，入炉煤颗粒平均粒径在燃烧早期迅速减小，而后随着燃烧的进行而逐步趋于一个稳定值；亮煤在流化床燃烧中服从等密度燃烧模式，暗煤服从等直径燃烧模式，而灰煤则服从混合燃烧模式。

The ethanol extract was dissolved with HCl, the acidic extract was basified to pH9-10 with NH_3-water and extracted with CHCl_3 to give total alkaloids. five alkaloids were isolated with column chromatography and preparative thin-layer chromatography, and three of them were identified as dehydrocorydaline、 corynoline and dihydrosanguinarine on the basis of spectral analysis MS,~1H-NMR,~(13C-NMR and physicochemical properties. All of them were found for the first time from this plant.

为研究灰绿黄堇的化学成分，本文将灰绿黄堇乙醇提取物采取酸提取、碱游离后萃取的方法得到总生物碱，然后利用柱色谱、制备薄层色谱等方法分离、纯化了灰绿黄堇中5种生物碱，并利用IR、MS、~1H-NMR、~(13)C-NMR等方法鉴定了其中的3种，分别为去氢紫堇碱、紫堇灵、二氢血根碱，均为首次在此植物中发现。

The paper proposes a method of image enhancement based on gray-levels in equal distance with interceptive way due to the drawback of histogram equalization with the phenomenon of over-enhancement and gray-levels annexation.

针对灰度直方图均衡化所引起的过增强和灰度级&吞并&等缺陷，提出基于截取法的灰度级等距离拉伸增强图像的对比度。

Geochemical study indicates that constant elements, microelements and trace elements in manganese ores and protore wholly take on thermal sedimentary characteristics, the siliceous limestone, silica-bearing limestone and bioclastic limestone is predominant protore beds of manganese-capped ores.

通过对锰矿石和矿胚层岩石中常量元素、微量元素及稀土元素等地球化学的研究，均具有热水沉积的特征，硅质灰岩、含硅质灰岩和生物碎屑灰岩是锰帽型矿石最主要的矿胚层。

Gravi ty and reentrainment were identified to be the main concerns. A simple reformati on of the ash hopper could be made to increase the ash separation efficiency wit h the addition of special devices.

研究结果发现，重力分离和二次夹带是灰斗气固现象中的主要矛盾，灰斗简单改型可以提高灰斗分离的效率，但工程应用仍需加装专门的分离装置。

You can start with the image of neutral grey zone for color cast judgement, and the region as the target tube do with gray scale of neutralized, that is, set the value with a neutral color cast of neutral grey area.

可以不后从图像的洋性灰地区怠工色偏鉴定，并以该地区为标的目的用滴管怠工同灰度级的洋性冻，即用洋性值撤销色偏的洋性灰地区。

I wrought again; and when I had made a good deal of fire-dust I emptied it into a handful of dry brown grass, intending to carry it home and keep it always and play with it; but the wind struck it and it sprayed up and spat out at me fiercely, and I dropped it and ran, when I looked back the blue spirit was towering up and stretching and rolling away like a cloud, and instantly I thought of the name of it-smoke!

我又开始劳作。我造出了许多火灰，然后我把火灰放在一束已经干枯得变成棕黄色的草叶里，打算带回家保存起来，能够经常同它玩；可就在这时，一阵风吹来，它便飞扬起来毫不留情地向着我身上扑来，我扔下火灰飞跑。等我回头望去，只见那蓝色的精灵已凌空跃起，翻滚着，扩散着，犹如一朵云，蓦地，我便想出了它的名字--烟！

Do you know, i need you to come back

你知道吗，我需要你回来
