To go beyond the normal or desired limit .All things considered, we shall add at least 300,000 cadres every year, or three million in ten years.

这几个方面加起来，每年最低限度要增加三十万左右的干部，十年就要增加三百万左右，实际上不止这个数。

We know from the statistics of past years, the total world demand for apple is a relatively slow process of changes and the inter-annual changes are less, generally about 6 million t. If Chinese export volume maintains at around 900, 000 t in recent years, it only takes up 3.8% of domestic gross yield 24 million (2005). The number accounts for 15% of world total export volume. If 10% of domestic gross yield is exported, it will account for 40% of world total export. If it increases to 20%, it will account for 80% of world total export.

我们从历年的统计可以知道，世界对苹果需求总量是一个较缓慢变化的过程，年际间变化较小，大体维持在600万 t 左右，如果近几年中国出口量维持在90万 t 左右，也只占国内总产量2400万 t （2005年）的3.8%，这个数量已占世界总出口量15%，如果以国内总产量10%用于出口，则占世界总出口的40%，如果提高至20%，则占世界总出口量的80%。

For example, although the fundamental of a trumpet is centred around 1200Hz, it generates strong harmonic components beyond 8kHz for the upper notes, with the implication that the harmonic series continues well into the ultrasonic region.

举个例子：虽然小号的中心频率在1200Hz左右，但它可以演奏在8KHz左右的高音，并可衍生出超声波范围的泛音。

Permanent magnet can provide for a maximum intensity of the magnetic field around Tesla, Helmholtz coils and solenoids can provide alternating magnetic field or relatively uniform magnetic field, and solenoids can also be used to provide strength for the solenoid around 10 Tesla.

其中永磁铁能够提供强度最大为1特斯拉左右的静磁场，亥姆霍兹线圈和螺线管可提供交变磁场或相对均匀的磁场，也可用螺线管提供强度为10特斯拉左右的超强静磁场，电磁铁则可产生强度为几百毫特斯拉或特斯拉级的静磁场。

Most headlights on low beam are useful to around 70 - 90 metres and high beam is good for 150 - 200 metres.

大部分近光灯的有效照明范围是在70～90米左右，而远光灯的有效照明范围是在150～200米左右。

Alcalase was the most effective enzyme to hydrolyze fibroin and the optimum conditions for the enzyme were around pH 9 and temperature of 60℃.

比较了多种酶对丝素的作用，其中Alcalase对丝素的水解能力最强，其作用最适pH为9左右，最适温度为60℃左右。
