关于b题的疑问?

<p>回28楼:</p><p>"你说第一问建航天器模型有啥意义，真搞不懂出题的怎么想的",建航天器模型是说明求高精度参数的重要性,因此才需要不断改进模型的参数估计,否则可能会有人认为捕食问题参数有必要估计那么准吗?</p>

<p>回29楼:</p><p>3问是用DATA2求解后做仿真，然后和DATA2做比较.</p><p>用DATA3求解后做仿真，然后和DATA3做比较.比较后,找差距,设法改进.</p>

<p>请问专家怎么感觉起始条件都是在其他参数确定后再确定的？？</p><p>还有<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: &quot;Times New Roman&quot;; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">2) </span><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-hansi-font-family: &quot;Times New Roman&quot;;">在观测数据无误差的情况下，</span><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-hansi-font-family: &quot;Times New Roman&quot;;">问至少需要多少组观测数据，发现不需要6组数据</span></p><p><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-hansi-font-family: &quot;Times New Roman&quot;;">望解答</span></p><p><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-hansi-font-family: &quot;Times New Roman&quot;;">谢谢</span></p>

<p>朱老师:</p><p>&nbsp;&nbsp;&nbsp; 您好!第3问中，我们找了一个模型,仿真结果比较已经精确了,还要改进模型?</p>

<p><font size="5">数据含有随机误差，用来处理数据的模型应该是非常有讲究的，改进模型问题应该就此而论。</font></p>

<p>请问专家 数据没有误差 在该题中是否可以认为数据符合所给模型呢</p><p></p>

请问专家：2题的2问，得到比例关系后，只能得到的是数值解，是不是？得不到精确解？<br/>
