Six internal and external factors, initial pH, culture temperature, fermentationtime, volume of medium, inoculum amount and rotation speed, which affected cultivation conditions for extracellular polysaccharide fermented by Ustilago maydis AS 5.128 were studied using Plackett-Burman Design.

采用Plackett-Burman设计(Plackett-Burman Design， P-B)对影响玉米黑粉菌AS 5.128发酵胞外多糖的内在和外在因素进行了筛选，所选取的6个相关因素为：初始pH、培养温度、发酵时间、装液量、接种量、摇床转速。

Speaking of embarks CVT not to have the section speed change system's vehicles, smooth accelerates the performance from is the born that way special skill, but as a result of product localization difference, very abundant under compares with the Lancer 2.0 liters vehicle types, the dynamic output is livelier, especially around 2,000 rpm slow-speed of revolution territories, the vaccinoid response to be quite agile, therefore drives in the urban district road section is quite relaxed.

对于搭载CVT无段变速系统的车辆而言，顺畅的加速表现自是与生俱来的特长，不过由于产品定位的差异，酷博在与Lancer 2.0升车型相较下，动力输出更为活泼，尤其在2，000 rpm前后的中低转速域，加速反应相当敏捷，因此在市区路段驶来颇为轻松。

However there is no satisfactory method a vailable to test torque speed curve of large power permanent magnetic motor.

电机的多项重要指标是否达到设计要求需要通过测试电机的转矩-转速曲线的结果来验证。

This engine benefits from variable valve A high-performance chassis for saloon-style driving sensations timing and camshaft variator which permits two types of use: one calibration for idling or when running partially loaded at mid and high revs for maximum power, and a second calibration which permits a bigger overlap between the intake and exhaust strokes for a torque gain of between 5 and 10Nm.

从可变气门的高底盘的轿车性能风格的驾驶感觉，时间和凸轮轴变速器的许可证或空转运行时有部分中的最大功率和高转速装两种用途：1校准这台发动机的好处，和第二个校准它允许更大之间的进排气重叠杆为5至10纳米扭矩增益。

By switching with these two brakes and the clutch, the vehicle may be switched in different driving modes; and controlling the rotation speed of the inner rotor can control the switching of the electrical stepless speed variator in different mixed driving modes.

切换两个制动器(9、5)，开闭离合器，车辆可在两种混联混合动力模式和纯电动模式之间自由切换。控制内转子(2)的转速可控制电力无级变速器在混联混合动力模式和并联混合动力模式间切换。

Pneumatic hammer drilling technology with low wob,low rate of revolution and high capacity to break rock is one of the best effective methods to solve the problems of hard rock drilling.It includes air drilling and rotary drilling technology,so its penetration rate is usually two or three times higher than rotary drilling.

空气锤钻井是一种低钻压、低转速、高冲击破岩回转钻进技术，它兼容了气体钻井和冲击回转钻井的优势，其机械钻速一般比回转钻井高，是当今解决硬岩钻井难题的一种有效方法。

Diamond bits require lower WOB,high rotary speed and small flow rate,useful for hole straightening and inclining prevention,and it can be used high-density drilling fluids.But diamond bits can′t effectively drill heterogeneous hard formations which contain chert,pyrite and silicastone.

金刚石钻头的钻压小、转速高、排量小，有利于纠斜防斜，可在高密度钻井液条件下使用，但它不能有效地钻进含燧石、黄铁矿和硅质的不均质坚硬地层。

Only noncrystal shapeless SiO〓 was separated by chemical processing, so noncrystal shapeless SiO〓 content obtained by roast products should be plentiful to the greatest extent in order to get desilication rate as high as possible.

正交试验和回归分析的结果表明，采用液固比为3，溶出温度413K，溶出时间15min，搅拌转速60rpm，颗粒粒径分布中。5μm的部分占60%左右，Na〓O〓浓度为100g/L的脱硅溶出制度是比较合适的。

The range of RPM for our couplings is from 600 to 1450 with power in range of 5 to 3500KW.

转速范围内为我们的联轴器是从600至1450年的权力范围的5至3500KW 。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
