- 脈沖數(shù) 分辨率 線數(shù) 都是同一個意思，只是叫法不同。 意思是編碼器旋轉(zhuǎn)一圈所產(chǎn)生的脈沖個數(shù)。

- 增量式拉繩（線）編碼器（位移傳感器）的幾個問題
- 1，信號是在拉伸或縮短的時候發(fā)送脈沖呢？還是累計下來的脈沖數(shù)周期性發(fā)送，能不能控制什么時候發(fā)，什么時候不發(fā)？ 2，沒有上電前，我先拉伸傳感器，然后固定，上電后有脈沖發(fā)送嗎？ 3，先縮短已經(jīng)拉伸的傳感器，再拉伸到原來位置，輸出的脈沖為0，還是代表... 1，信號是在拉伸或縮短的時候發(fā)送脈沖呢？還是累計下來的脈沖數(shù)周期性發(fā)送，能不能控制什么時候發(fā)，什么時候不發(fā)？ 2，沒有上電前，我先拉伸傳感器，然后固定，上電后有脈沖發(fā)送嗎？ 3，先縮短已經(jīng)拉伸的傳感器，再拉伸到原來位置，輸出的脈沖為0，還是代表移動了兩段距離的脈沖？ 展開

A new kind of TiO2 nanotube array/Ni(OH)2 (TiO2/Ni(OH)2) composite electrode with the storage ability of light energy was prepared by the deposition of Ni(OH)2 on the TiO2 nanotube array， which was synthesized by anodizing Ti foils in an HF aqueous solution. SEM and XRD results showed that Ni(OH)2 particles were well distributed on high density， well-ordered and uniform TiO2 nanotube arrays. The photoelectrochemical properties of the TiO2/Ni(OH)2 electrode were investigated in NaHCO3/NaOH buffer solution (pH 10) by means of UV–vis absorption spectra， cyclic voltammogram (CV) and photocurrent measurements. It was found that the TiO2/Ni(OH)2 electrode was highly sensitive to light and exhibited excellent photoelectrochromic properties. Upon UV irradiation， the photogenerated holes by TiO2 nanotube arrays can oxidize Ni(OH)2 to NiOOH， and thus the TiO2/Ni(OH)2 electrode can be photo-charged by light。1. Introduction Among many visible light photocatalysts， TiO2nanostructures have attracted much attention due to high photocatalytic activ-ity， nontoxicity， chemical stability and huge potential applications [1–6]. The TiO2 nanotube array is one of most attention-getting TiO2nanostructures because of large surface area and outstanding charge transport properties. TiO2nanotube arrays can be utilized in dye-sensitized solar cells[7–9]， photocatalysis and hydrogen gas sensing [10]. So far， a variety of methods have been attempted to prepare TiO2 nanotube arrays， such as hydrothermal synthe-sis[11]， Langmuir–Blodgett technique [12]， solution casting [13] and anodization technique[10，14]， etc. Among these methods， the anodization technique has many advantages of low cost， low tem-perature and easy to be scaled up to large-area preparation. Recently， anewkindof photo-functional systemwith theenergy storage ability has been developed by coupling TiO2 photosen-sitive electrode with energy storage materials. In Takahashi and Tatsuma’swork[15]，aTiO2/Ni(OH)2bilayer thinfilmwas suggested for the oxidative energy storage. In this case， a redox-activep-type semiconductor Ni(OH)2is coupled withn-type TiO2photocatalyst to formap–njunction，WhenTiO2is illuminatedby light， holesgen-erated at the junction are separated from excited electrons， trans-ported into the bulk of Ni(OH)2and oxidized Ni(OH)2to NiOOH. Therefore， the oxidative energy storage system was constructed 展開
