mso-font-kerning: 1.0000pt;">故障五:</span>P<span style="line-height: 150%; font-family: 宋体; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;;

mso-font-kerning: 1.0000pt;">稳定性不好,检查真空泵是否被误关掉,真空光路镜片是否需要清洗,一个维护不好的光路会导致错误的重现性和分析结果。</span></span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">处理办法:检查真空泵及清洗镜片。</span></p><p style="margin: 0pt; text-align: center; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;;

line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">处理办法:看真空值曲线是否平缓,否则,有漏气的地方,检查真空室真空盖密封性,更换密封圈或对角紧固螺丝。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">&nbsp;</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;"><span style="color: rgb(0, 0, 0);

line-height: 150%; font-family: 宋体; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">透镜脏;</span>②<span style="color: rgb(0, 0, 0); line-height: 150%; font-family: 宋体; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">入射狭缝污染;</span>③<span style="color: rgb(0, 0, 0); line-height: 150%; font-family: 宋体; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">光纤老化</span>&nbsp;</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">处理办法:擦拭透镜,清理狭缝,更换光纤。经验总结:光谱仪用久了,激发台会因点打的太多了,出现放电漏气现象,导致光强上不去,需要经常清理激发台板及火花室。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">&nbsp;</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">故障八:数据不稳定。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">处理方法:清洗镜片后重新做标准化,仪器镜片的污染会导致数据测试的结果不稳定,长时间没有做仪器的曲线校准也会导致数据测试稳定性不好。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">&nbsp;</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;;
