This paper introduces the design of temperature acquisition system which is based on the PXI-6251 DAQ device
thermocouple acquisition module SCXI-1102 and the LabVIEW program language of NI. The design of temperature collection software and the configuration of hardware are described in details. The software developed in LabVIEW program language can acquire temperature data rapidly
what's more
the acquired data can be displayed real timely and saved to the disk. It is proved that the system is easy to practical use and can extraction mean square value and mean value after gathering the stable high-speed temperature. The function can be extended according to the demands of users. 2012 IEEE.

Since CVD diamond film possesses desirable properties
it has been widely investigated
and much research has been made in this field. In this experiment
we mainly studied the characteristics of field emission from the CVD diamond films. The motivation for the experiment is to gain some insight into a possible emission mechanism. The diamond films are grown using a hot filament chemical vapor deposition
basing on the diamond micro-grits on silicon substrates. And the diamond micro-grits are deposited on silicon substrates using electrophoresis coat method
through a solution of diamond micro-grits in ethyl alcohol. This study has revealed that emission can be obtained at fields as low as 1.8V/m. And the field emission measurements were carried out at a pressure of 10-4Pa.

Carbon nanotubes have been attracting attention because of their unique physical properties and their application potential for field emission cathode. Carbon nanotubes possess the following properties favorable for field emission material
such as a high aspect ratio and sharp tip
high chemical stability
high mechanical strength
stable at high temperature. Some research works on carbon nanotubes field emitter and field emission display have been reported. Here
a kind of carbon microtubes and its field emission properties are introduced. They have some different properties with carbon nanotubes
and the density is lower than carbon nanotubes bundles. These carbon microtubes are directly synthesized by liquidoid epitaxy method on silicon substrates at low temperature. The field emission properties of carbon microtubes are reported too. Carbon microtubes film is synthesized in liquid by electrolysis. The graphite plate is as anode
and n-silicon substrate with resistivity of 4-8 cm is as cathode. The electrolysis current is about 5-8mA/cm2
and applied voltage is 800-1500V. Temperatures of the methanol base solution is maintained at 60C in process of deposition of carbon microtubes. Carbon microtubes film is observed by scanning electron microscopy(SEM)
as shown in fig.1(a
b). The wall's thickness of carbon microtube is about 60nm. The diameter of carbon microtube is about 0.8 m. Raman spectrum of carbon microtubes film shows the two peaks at 1342and 1560cm-1. The field emission properties of carbon microtubes are measured in high vacuum chamber(10-5Pa). The emission area of carbon microtubes is 0.5cm 0.5cm. The threshold of field emission of the carbon microtubes film is about 3.6V/ m. Field emission property of carbon microtubes film is shown in fig.2. Another
when the electric field between anode and cathode is 10V/ m
the electric field distribution on single carbon microtube is also given after calculation according to electric field theory. Fig 3 shows that electric field distribution vertical section on the of single carbon microtube top with 2 m of highness. These results may help us to understand field emission properties of carbon microtubes. According to research results
it is found that liquidoid synthesis is simple method to produce carbon microtubes cold cathode material
and the carbon microtubes have better field emission properties. 2005 IEEE.
