摘要

Abstract > Within a full‐factorial laboratory experiment, three different designs and two modifications of typical manual closed chamber setups were tested for sealing integrity. Tests were performed using a simple method, based on injections of single CO <sub>2</sub> pulses. Chamber designs differed in V:A‐ratio and chamber‐collar sealing (water, rubber‐foam, rubber‐tube). All chambers were tested with and without pressure vent and fan. Our results indicate significant differences in sealing integrity due to chamber‐collar sealing strategy. Especially rubber sealing turned out to be characterized by a certain non‐reliability. The effect of vent and fan, however, was of minor importance. The proposed setup is an effective way to assess the airtightness of manual chambers for subsequent field studies. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”> abstract </ title> > 全源实验室实验，三种不同的设计和两种典型手动闭合室设置的修改，用于密封完整性。基于单一CO <sub> 2 </ sub>脉冲的注射，使用简单方法进行测试。腔室设计不同于V：A比和室轴环密封（水，橡胶 - 泡沫，橡胶管）。所有腔室都有和无压力通风口和风扇测试。我们的结果表明由于腔室密封策略引起的密封完整性的显着差异。特别是橡胶密封，以某种不可靠性为特征。然而，通风口和风扇的影响很小。建议的设置是评估手动房间用于后续实地研究的有效方法。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35667/'>《Journal of plant nutrition and soil science》</a> <b style="margin: 0 2px;">|</b><span>2018年第1期</span><b style="margin: 0 2px;">|</b><span>共5页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hoffmann Mathias&option=202" target="_blank" rel="nofollow">Hoffmann Mathias;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Pehle Natalia&option=202" target="_blank" rel="nofollow">Pehle Natalia;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Huth Vytas&option=202" target="_blank" rel="nofollow">Huth Vytas;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Jurisch Nicole&option=202" target="_blank" rel="nofollow">Jurisch Nicole;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sommer Michael&option=202" target="_blank" rel="nofollow">Sommer Michael;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Augustin Jürgen&option=202" target="_blank" rel="nofollow">Augustin Jürgen;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Institute of Soil Landscape ResearchLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> <p>Institute of Landscape BiogeochemistryLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> <p>Institute of Landscape BiogeochemistryLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> <p>Institute of Landscape BiogeochemistryLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> <p>Institute of Soil Landscape ResearchLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> <p>Institute of Landscape BiogeochemistryLeibniz Centre for Agricultural Landscape Research (ZALF)Eberswalder Str. 84 15374 Müncheberg Germany;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/212.html" title="农业基础科学">农业基础科学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=chamber‐collar sealing&option=203" rel="nofollow">chamber‐collar sealing;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=chamber leakage&option=203" rel="nofollow">chamber leakage;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=non‐steady‐state chambers&option=203" rel="nofollow">non‐steady‐state chambers;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=wind shelter&option=203" rel="nofollow">wind shelter;</a> </p> <div class="translation"> 机译：室内衣领密封;腔室泄漏;非稳态腔室;风庇护所;
