In order to acquire the accurate signal from the noisy surrounding and get the relevant information about the gasohol from a lot of complex spectrogram which are made up of signals with a series of wavelengths, a compact, energysaving portable near infrared analyzer was designed to determine the content of water and ethanol in gasohol.

为了保证在恶劣环境下提取出高质量的电信号以及从众多波段的电信号组成的光谱图中准确地提取出乙醇汽油的相关信息，确保工作人员能利用仪器方便地确认乙醇汽油中乙醇和水的含量，提出了体积小、功耗低的便携式近红外乙醇汽油分析仪的设计方案。

When there are two connections to earth, such as when the source and measuring instruments are both connected to a common ground bus, a loop is formed as shown in Figure 3-11a.

当存在两个与地的连接点，例如源和测量仪器都连到一个公共的地总线时，就形成了如图3-11a的回路。

The BMD of right hind leg is obviously different from that of left hind leg in cancellous bone (P.01). Conclusions The pQCT can sensibly discern various regions of skeletal changes 6 weeks after unilateral sciatic neurectomy.

大鼠切断右侧坐骨神经后，通过pQCT仪器测定，能灵敏、精确地获得骨密度的变化，并有效地区分各个不同结构的特征。

Using the world's most exacting equipment, Nilsson reveals the interior form of the entire human body and its intricate workings as never seen before, in a book that is as stunning to behold as its contents.

使用世界的最苛求的仪器， Nilsson 显示那内部形式的同样地从不以前见到的整个人类的身体和它的复杂工作，在一本同样地是足以使人晕倒看到如它的内容书中。

It can be used to demonstrate such as optical axis of the uniaxial crystal,principal plane,the ordinary wave front and the extraordinary wave front ,etc.

该仪器用于普通物理光学教学，能形象生动地演示单轴晶体中的光轴、主平面、o光和e光的波面、o光和e光各自的电矢量的振动方向、速率大小关系，并能灵活地结合课堂教学各种实例，说明在不同条件下，双折射的产生及其原因

It contained system principle block diagram, exposition to the main part, circuit and software flow chart. The test of volt-ampere characteristic to sample tester were provided. It is easy to find that this tester has very good performance according to the test result and it is a more practical.

详细地给出了该测试仪的系统实现原理框图，并对其中的主要部分进行了详细地阐述，给出了相应部分的电路原理图，以及软件实现流程图，并通过对所设计的样机进行了伏安特性的测试，根据测试结果可以看出，该测试仪具有很好的性能，是一个比较实用的测试仪器。

The specimen horizontally into two of the instrument, sample between the edge of the circular underpan between the minimum distance of not less than 50-mm, measurement should be gently 2 ~ 3 mm/min will activities on blank sample in order to avoid any impact, and make sure the piece and thickness measurement plane parallel.

将试样水平地放入仪器的两个平面之间，试样的边缘与圆形底盘边缘之间的最小距离不小于50mm，测量时应轻轻地以2～3mm/min的速度将活动平面压在试样上，以避免产生任何冲击作用，并保证试片与厚度仪测量平面的平行。

Was floated on still water in a bowl, the head of the fish pointed to the south and the tail to the north. Over years, this fish-shaped device gradually evolved into the more simple and convenient form of an iron needle.

在使用指南针的过程中，人们不断地改进，不断地摸索，使指向仪器在外形上终于成为最简便的针形。

Whether students or teachers, are free and without hesitation to operate at any time to enter the virtual laboratory apparatus, to carry out various experiments.

无论是学生还是教师，都可以自由地、无顾虑地随时进入虚拟实验室操作仪器，进行各种实验。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。

If you can benefit from this book, it is our honour.
