At first, the broth was acidified, then centrifuged to get mycelia, which was heated and powdered; finally we use acetic ether to soak the powder. After that, the phase of acetic ether was washed using the solution of ammonium sulfate and the solution of ethanedioic acid, then concentrated to gain pulps. It was crystallized at 4℃.The coarse crystals was decolorized by activated carbons, the pure needle crystal of lovastatin was obtained.

发酵液经酸化处理后，离心得到菌体，烘干后过筛得到菌粉；用乙酸乙酯浸泡，乙酸乙酯相需用(NH_4)_2SO_4溶液和草酸溶液洗涤两次；乙酸乙酯相经薄膜浓缩得到浆状物，于4℃结晶，得到粗晶体；再经粉末活性炭脱色和重结晶后得白色针状结晶，为lovastatin的纯品。

One manner in which such extremes may be resolved is in the re-empowering of underpowered nations.

解决这些极端的一种方法是重赋力量于在权力下的民族。

In order to calculate the helicopter hover ceiling in OGE precisely, some aerodynamic parametem, such as tip loss effect, induced velocity distribution, the effect of rotor downwash on the fuselage and power transfer of engine into rotor, must be treated carefully.

准确计算直升机的悬停升限依赖于诸如桨尖损失系数，非均匀旋翼诱导速度分布，旋翼下洗引起的直升机增重效应及发动机与旋翼之间的功率传递系数等气动参数的准确度。

In young pigs weighing approximately 10kg given three or five times the therapeutic dose transient signs attributed to injection site discomfort were observed and included escessive vocalisation and restlessness.

在幼猪重约10公斤给予3或5倍治疗剂量短暂的不良反应可归因于注射部位不适，另包括escessive vocalisation和不安。

Methods Twenty SD rats were randomly divided into two groups. The left phrenic nerve or accessory nerve was transferred to femoral nerve by the vascularized ulnar nerve bridging in Group A and Group B, whereas the right femoral nerve remained the disjunction. The electromyogram and wet weight, throughput and section area of myelinated nerve fibers, and section area of muscle fibers in quadriceps femoris muscle were determined after 24 weeks.

大鼠20只，随机分为A、B两组，每组10只。A组：左侧行膈神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合，作空白处理。B组：左侧行副神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合。A、B两组于24周后观察股四头肌电生理、有髓神经纤维通过率及截面积、股四头肌湿重比、肌纤维截面积比等指标。

Guericke's demonstration was presented on 8 May 1654 to the Reichstag and the Emperor Ferdinand III in 1654 in Regensburg, where 30 horses, in two teams of 15, could not separate the hemispheres until the vacuum was released. In 1656 he repeated the demonstration with 16 horses (2 teams of 8) in his hometown of Magdeburg, where he was mayor.
