有缺点的

From what has been discussed above, we may safely draw the conclusion that, although extra studies inde ed enjoy many obvious advantages, its disadvantages shouldn't be ignored and far outweigh its advantages.

通过以上讨论，我们可以得出结论：尽管额外学习的确有很多优点，但它的缺点不可忽视，且远大于它的优点。

However, It has long been known that ROIs, particularly on functional images, is time-consuming, subjective, irreproducible and prone to operator bias.

这对肿瘤，神经精神疾病以及认知的研究领域都有应用，可是由于受到图像分辨率和主观因素的影响，ROI存在着解剖区域勾画不准、主观性强和重复性差等缺点。

Thanks to my weakness—never consider the consequence.What I know ismy oral English is plain, but what I don't know is what if I make itterrible .

不过我们还是行动了，我觉得我有一个缺点，就是很少去想做事的后果会怎么样，但用在这里，就成了长处了，我只知道自己的口语一般，但没有去想，如果说砸了该怎么办。

So I think our students should be allowed to use moble phones in school, anyhow, its advantages have an advantage over its disadvantages.

If something doesn't work quite right the carpetis worn ,the toilet or bathroom basin leaks or you have a bad neigher ,you get used to them and like your own shortcomings,you find ways to ignore them.

If东西不能正常工作非常正确的carpetis破旧，厕所或浴室盆地泄漏或你有一个坏neigher ，您可以用他们喜欢你自己的缺点，你找到办法，忽视他们。

From what has been discussed above,we may safely draw the conclusion that,although extra studies indeed enjoy many obvious advantages,its disadvantages shouldn't be ignored and far outweight its advantages.

通过以上讨论，我们可以得出结论：尽管额外学习的确有很多优点，但它的缺点不可忽视，且远大于它的优点。

The conventional liquid based RP system used a special designed recoat to scrape resin from one side of the tank to the other to ensure the surface flatness. The scraping procedure will take off extra resin but with a drawback of shear force to the working part. In order to overcome the drawback of the shear force, a supporting structure is necessary to build under the working part.

目前商业化之液态快速原型系统中，大部分使用刮板铺层进行层厚控制的部份，铺层系统铺过工件表面时，微小结构容易受到刮板所产生的剪切力破坏，为了克服剪切力这个缺点，使能制作出具有外悬机构原型时，必须建立支撑结构。

But the synthetic and transcripted siRNA in vitro have some disadvantage such as poor stability and manipulability、 transitory restrainability、can not be inherited and can be easily decompounded by abroad existing RNA enzyme.

However, various intrinsic problems exist in a conventional DLL such as narrow operation frequency range, harmonic locking, lack of frequency synthesis function, mismatch among delay stages, and unsuppressed VCDL noise.

但是，传统延迟锁相回路却有著较小操作频率范围、缺乏频率合成弁遄B压控延迟线中相位间不匹配、及压控延迟线的杂讯不能被压制等缺点。使得延迟锁相回路的应用范围受到限制。

The split between the two groups can hardly be papered over.
