【正文】 單壁碳納米管有效的物理性能如下，這是由原子間力的利米提出碳晶格常數(shù)場的作者在 2021 年計算的 L = ， dNT0 = ， rinit = 6nm，高 = Eeffective = （圖 8和 9）。最近的系統(tǒng)，也可以在任何愿望的壓力開關，它是通過決議索取檢測范圍內是（它的壓力感應范圍從零和使用單壁碳納米管的壓力是第一次轉換）。 結果，建議的壓力開關的結構由一個兩端固定的單壁碳納米管組成，一個導電地平面和可調諧電壓源包含單壁碳納米管和地平面的電壓（圖 7）。因此，它沒有解析解。從圖 3可以看出θ er 是單壁碳納米管直徑的函數(shù)。 王和 Varadan在 2021年證明，這種不穩(wěn)定性是因為單壁碳納米管彎曲扭結條件下，當在壓力側內壁應變能量達到臨界值時，已經被高分辨透射電子器觀察到。結論，對 Pt1尺寸是： 吸合現(xiàn)象 Dequensnes 在 2021年已經證明當單壁碳納米管和導電地平面之間有電壓時，單壁碳納米管偏轉。因此，單壁碳納米管在面對的壓力高于它的過渡壓力時經歷了一次較大的變形。在第一階段，單壁碳納米管在壓力下其橫截面部分統(tǒng)一地均勻地減少，這是碳碳鍵統(tǒng)一長度減少所致。此開關的傳感壓力范圍的上限是第一個單壁碳納米管的限制壓力。結論，壓力傳感器只能夠感應一定數(shù)值的壓力（單壁碳納米管的過 渡壓力）（圖 1和 2）。它的壓力傳感系統(tǒng)有能力感知單壁碳納米管開關從導電材料的變化到半導電物質。在靜水壓力作用下，單壁碳納米管的截面按比例均勻減少所施加的壓力，直到它達到單壁碳納米管的第一個短暫的壓力。 I 在這種情況下，由于單壁碳納米管在水平面的塌陷，在它們 之間的就會有連接使電路斷開。此外，單壁碳納米管的扭曲，由于彎曲的通道在水平面上變得不穩(wěn)定和塌陷。s initial diameter (at zero pressure) and E is its effective young Modulus () To calculate the Pullin voltage, elastic and electrostatic domains should be considered. Van der Waals forces are quite small in parison to electrostatic force。s. However, the number of used SWNT39。s first transition addition, SWNT kinks,bees unstable and collapses on a ground plane due to bending phenomenon is a function of SWNT diameter. Bending loads can be generated by inducing a voltage between SWNT and a conductive ground plane. Therefore ,by inducing a certain Pullin voltage relative to a certain diameter(pressure), SWNT does not collapse until the applied pressure reaches to a certain amount which causes a certain SWNT diameter this case, because of SWNT collapse on the ground plane, there will be a connection between them closing an electric this study, these characteristics are employed to introduce a tuneable pressure switch. This type of pressure switch,in parison to previous presented one, uses only one SWNT for switching, is able to sense pressure with higher resolution and has a much simpler system. Key words:Single wall carbon nanotube, pullin voltages, electrostatic bending forces, kink, phase transition, transient pressure INTRODUCTION Single Wall Carbon Nanotubes(SWNTs) has novel mechanical properties and behaviors which have attracted many considerations and studies recently. Under hydrostatic Pressure, SWNT39。s cross section is reduced uniformly and proportionally to applied pressure, u
