Porsche 911: A long running myth of power and design

保时捷911型跑车：一部经久不衰的动力神话

To fill the level adjustment system, use the Porsche system tester.

若要加注水平调节系统，请使用porsche系统检测仪。

Now we study a night light is aimed at this one defect was improved, can be in Windows startup tubes, reduce within masses manufacturers in darkroom need outfit photosensitive lamp of trouble.

现我们研究出黑夜之光，就是针对这一缺点进行改进，可以在暗盒内启动灯管，减少广大生产厂家在暗室中需要装感光灯的麻烦。

You can find the Porsche Cayenne everywhere!

你会发现保时捷无处不在。

Pregnant women are also advised not to eat soft blue-veined cheeses, such as Danish blue, gorgonzola and Roquefort.

孕妇也被建议不去吃柔软的有青筋的奶酪，例如丹麦蓝，干酪和羊乳干酪。

The Stuttgart, Germany-based automaker built this car to help its bottom line in the same way the Cayenne did 10 years ago& and from the looks of things last night, it fills that small-SUV gap nicely.

这家位于德国斯图加特的公司之所以打造这款车，是为了像10年前推出卡宴一样帮助增加利润，从当晚的发布情况来看看，该车完美地填补了小型SUV的空白。

Grafting Bentley flesh onto a skeleton borrowed from Cayenne is far less costly than developing from scratch.

在卡宴的骨架上植入宾利的血肉要比从头开发省钱多了。

Cayenne-Also known as capsicum, it plays a very large role in blood circulation.

卡宴-也称为辣椒，它发挥了非常大的作用，血液循环。

Indeed, it's very Porsche, sharing the side angles of a 911 and the height of a Cayenne-its front end is also very similar to its bigger brother-while repping even the Boxster a bit in the styling of its air intakes and side profile.

事实上，这款车非常“保时捷”，采用与保时捷911相同的侧角，与卡宴（Cayenne）相同的车高——车身前部也非常类似于这位老大哥，此外甚至进气格栅和侧边轮廓都略微模仿了Boxster的风格。

The causal pathogens of rice damping off were mainly Rhizoctonia solani, secondly were Fusarium spp.

试验表明水稻立枯病菌主要是由Rhizoctonia solani引起，其次是Fusarium SPP。
