在27条狗中，有24只狗的鼻黏膜上皮细胞发现有病毒抗原；有24只足垫上皮细胞中出现病毒抗原；有26条的覆毛颈背皮肤中发现有病毒抗原

Indeed, Cook and coauthors found evidence that Charon's surface composition differs between its Pluto-facing and anti-Pluto faces, with the sub-Pluto face showing deposits of more ammonia-rich ammonia hemihydrate (NH3 · 0.5H2O) and the anti-Pluto face more water-rich ammonia dihydrate (NH3 · 2H2O).

的确，Cook 同合著者们发现了喀戎表面朝向冥王星一面和背向冥王星一面间成分差异的证据，向着冥王星一面的沉积物表现出较多的富氨的半水合氨（NH3 · 0.5H2O），背向冥王星的一面有较多的富水的二水合氨(NH3 · 2H2O)。

Fruit dry, of two mericarps united by their faces, and usually attached to a central axis, from which the mericarps separate at maturity; mericarps are variously flattened dorsally, laterally or terete; each mericarp has 5 primary ribs, one down the back, two on the edges near the commissure, and two between the dorsal and lateral ribs, occasionally with four secondary ribs alternating with the primary, the ribs filiform to broadly winged, thin or corky; vittae usually present in the furrow (intervals between the ribs sometimes called the valleculae) and on the commissure face, rarely also in the pericarp, sometimes obscure.

果干燥，二分果瓣，通常附着在果瓣柄上，成熟时分离，分果瓣背面不同程度扁平，横向或者圆柱状；每分果瓣有5条主棱，一条背棱，2条侧棱，3条中棱，有时有4条与主棱互生的次级棱，棱丝形到形成宽翅，薄或木栓质沟槽和分果的合生面通常有油管（在棱和棱之间有沟槽，很少果皮上有油管，有时不明显。

I remember I was young, often sick, my mother often took me up at midnight to see a doctor, there is a problem evening, the weather was cold, I was a fever, and my father on a business trip, my mother carrying me to see a doctor that ah, the wind kick into gear in blowing, the rain, under the gentle, the way her mother walked step by difficult step, has a few four meters away, my stubborn back down from the mother may be his mother always refused, and thus, I Mama's back, hands holding the umbrella, my mother literally let loose upon me to look inside an, to the hospital, my body is dry, it may mother body is wet, the night quietly, and the hospital is quiet, the pommel horse They pulled my hospital, went to the pediatrician, the doctor is still on duty, watching us, and then hastily let us sit down, asked a question, it would be opened to us, but, my mother went to make the drug, to the nurse aunt, after a while, medicine to accompany out, marked with a pin for my mother has accompanied me until I got home after the kick down the needle, she went to bed for a while, looked at the mother look like fatigue, I am a heart, both warm and feel guilty.

记得我小时候，经常生病，妈妈经常半夜起来带我去看医生，有一题天晚上，天气很冷，我又发烧了，爸爸出差了，妈妈这啊背着我去看医生，风呼呼的刮着，雨轻轻的下着，路上，妈妈一步又一步艰难的走着，已经走了几四米了，我倔强的要从妈妈背上下来，可妈妈始终都不肯，就这样，我在妈妈背上，手拿着伞，妈妈硬是让后我把散往里安，到了医院，我身上是干的，可妈妈身上却是湿漉漉的，夜静静的，医院里也是静悄悄的，鞍马们拉着我在医院挂号，走到了小儿科，医生还在值班，看着我们来了，便急忙让我们坐下，问了问情况，便给我们开了要但，妈妈又去令了药，给了护士阿姨，过了一会，药陪出来了，为我打上了针，妈妈又陪着我直到我打完针回到家后，她才去睡了一会，看着妈妈疲劳的样子，我是心，既温暖又感到愧疚。

For example, in the process of drafting have given a clear map elements, are the properties of the overprint, conprehension of wirelike or areal symbols, or the line and the region of Kaitsu and trapping; whether it is selected, how they trap; business card printing and membership card making use of four color, spot color, or they are on the net, how to use will not be a problem; even need a computer screen is displayed on the color line, and font and its size can be made deliveries to the printing plate.

比如：制图历程洋给差每一舆图给素给定分明的属性，是否选叠印、是纯真的线状还是背状标记、或者是线和背域皆而有之；是否选陷印、陷印的办法如何；制卡和会员卡制息是拔取四色、专色还是它们的浅网色，怎么搁置才不会不入题纲；甚至需给存眷计算机屏幕上表示的线划、撤色和字体及其巨细可否制得不入印版。

Because the CMYK color business card printing and making basic membership card is based on the dot to overprint colouration and instead use spot color is basic to business card printing and membership card production, although typically spot color is only partial use of the image, but valuation, it is conventional to general printing inks price to estimate; in addition, if the same suites have four business card printing and membership card making color, cards and membership cards for the purpose of making is tantamount to another color, if the business card printing and membership card making machines have no spare business card printing and membership card production unit (for example, less than four color business card printing and membership card making machine or four-colour business card printing and membership card making machine), you have to spend double the amount of real time business card printing and membership card production cost is higher.

因为CMYK四色制卡和会员卡制息根基因此网不背叠印呈色，而搁置专色则根基以实不天制卡和会员卡制息，尽管凡是专色只是在图像的部分搁置，但估价时，不惯上却因此凡是印墨的两倍代价来估算的；此外，如果同版背还来有了四个制卡和会员卡制息色，差制卡和会员卡制息而言不离即是众了一个颜色，如果制卡和会员卡制息机操纵众余的制卡和会员卡制息单位（如超出四色的制卡和会员卡制息机或四色制卡和会员卡制息机），不离又给众花一倍的工夫来制卡和会员卡制息，不败本也不离更高了。

The brutish sea takes fingerling as to eat, can to the head which swims it nearby inch remaining to grow fish but never attackstone, because the head fish pecks at sea the parasite of the body, easing pain and sufferings of the sea ; Have Tibet a kind of brown carry on the back a ground of crow, make it a rule an underground and produce egg and teach son, often live in the same of cave inside, rat or rabbit with the animals, such as rat and rabbit...etc. and beat hole and build nest for the ground crow, the ground crow stands guard and sets up patrol for rat or rabbit, also often often signing in the rat or the rabbit and carrying on the back up, peck at parasite, is a very typical symbiosis phenomenon.

凶恶的海鳝以小鱼为食，可对游到它身边寸余长的隆头鱼却从不攻击，因为隆头鱼啄食海蟮身上的寄生虫，减轻了海蟮的痛苦；西藏有一种褐背地鸦，习惯地下产蛋育儿，常和老鼠或兔子等啮齿类动物居住在同一个洞穴里，老鼠或兔子为地鸦打洞筑巢，地鸦为老鼠或兔子站岗放哨，还常常立在老鼠或兔子背上，啄食寄生虫，是颇为典型的共栖现象。

Because WangGan was so remote that the nearest village to it was about five kilometers away, a road accompanied by a muring river streaming out, the road was so winding , the river arrived a place which wild beast often appeared and about thirty families lived there, nobody would get married with people who lived there, only the girls who living there would go out, Though the villagers there often suffered from famine, there was some grain left every year, so wise young men only got married with women who had got married for a time.

他回到村里时，&灶背田螺&早改嫁了王干村的一个比她小10来岁的帅哥，因为王干太偏僻，离最近的村庄也有10来里的山路，一条小路顺着一条潺潺流出的小河，弯来曲去，一直到王干这个住着30来户人家的野兽出没的地方，没人愿意嫁进去，只有那里的姑娘愿意嫁出来，虽然这地方在别处闹饥荒时它那还有余粮。所以再帅的哥们也只好娶了&灶背田螺&这样的二婚媳妇。

In the computer chassis before and after the panels are left in USB interface, we should, if possible, mobile hard drive inserted into the chassis back panel USB port, after all, the back panel of the USB ports are integrated directly into the computer motherboard, this USB port are generally considered safe grounding design, we found the body of the static it becomes hard to move a threat to the safety of the hard disk USB interface.

在电脑机箱前后面板中都留有USB接口的情况下，我们应该尽量将移动硬盘插入到机箱背面板上的USB端口中，毕竟背面板上的的USB端口通常直接集成在计算机主板中，这种USB端口一般都有安全接地的设计考虑，所以我们人体身上的静电就不大容易威胁到移动硬盘USB接口的安全。

Results show that the performance of this VCRT basically reaches the original objective,which indicates that a convergent-divergent blade passage in the high pressure rotor and a convergent-divergent meridian plane of the VCRT are suitable for the VCRT.

结果表明，对转涡轮各方面性能基本达到了设计目标，说明高压动叶采用收扩型叶栅通道且整个涡轮子午流道也采用收扩结构的设计可以获得满意性能；三排叶片仍有改进余地，即涡轮效率还有进一步提升的潜力；高压动叶出口沿整个叶高均为超声速，出口马赫数节距平均值在1.4~1.6之间；高压动叶尾缘斜激波强度以中展为中心向两侧递减；涡轮性能随出口背压的增加而下降；涡轮出口背压的变化对高压转子性能基本没有影响，但对低压转子性能的影响较大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
