Q-Box便携土壤呼吸测量系统
（Q-Box SR1LP Soil Respiration PacKage ）
The Q-Box SR1LP Soil Respiration Package provides the user with all of the materials required to measure soil respiration using an open-flow gas exchange system when the rate of respiration is high, or as a closed-flow recirculation system when the rate of respiration is low. The Battery Pack ａnd Charger allow the use of the package in the field conditions. Air is pumped at a known flow rate through the soil chamber ａnd sensors. The concentration of CO2 in the air is determined using the Q-S151 CO2 Analyzer. In the open-flow system the difference in CO2 concentration entering the flow through the cuvette holding the soil sample ａnd exiting it is used to calculate the rate of respiration. In a closed-flow system the initial rate of CO2 accumulation in the soil chamber （placed on top of the soil surface） is used to determine the rate of respiration.
（Q-box 便携土壤呼吸系统可以作为一个开放的测量方式，也可以选择闭合式的土壤再循环测量系统，便携箱含电池，抽气泵可以测量流量，通过q-s151二氧化碳分析仪测量二氧化碳浓度，在开放式系统中通过土壤测量不同的二氧化碳浓度，用于计算呼吸速度。）

In addition to soil respiration Q-Box SR1LP package allows measurements of soil temperature with the S132 temperature probe ａnd water loss from the soil with the S161 Temperature/Relative Humidity sensor. The flow through the system is monitored by the Q-G266 Flow Monitor. The Analog signals from all of the sensors ａnd analyzers are converted to digital signals via two integrated LabQuest mini interfaces （6 channels）. Data is displayed, recorded ａnd manipulated on a PC or Macintosh computer using Logger Pro software.（土壤呼吸sr1lp系统，可以测量土壤的温度湿度和二氧化碳交换计算呼吸速率。通过q-g266系统监测流量。通过综合labquest迷你接口，传感器可输出模拟信号和数字信号。带现场显示，记录数据，电脑通信软件）

Sample soil respiration data from a closed-flow system:（闭合式土壤测量系统数据）
Q-Box SR1LP software provides calculation templated for determination of soil respiration rates.（SR1LP软件可计算土壤呼吸的速率与状态）
There are many other potential applications for Q-Box SR1LP package both in open flow ａnd closed gas exchange systems. For example, it can be used to measure CO2 exchange from any organism or sample maintained in a flow-through chamber. In addition, it can be used to examine respiration or fermentation in aqueous suspensions when air or N2 is bubbled through the suspension ａnd the outflow gas is analyzed using the CO2 Analyzer. Provided that CO2 production rates are in the correct range, the package can be used to measure CO2 production of virtually any biological system.
