the sample temperature is controlled with a fluid circulator 样品温度是由一个流动的循环器来控制的。
the ctd600 distinguishes itself by a very large temperature range and a virtually gradient-free sample temperature ctd600最大的特点是温度范围非常宽且样品不会出现温度梯度。
the sample temperature was controlled by a chromel _ alumel thermocouple with a precision on the order of 0.1 此次田间试验的目的,是研究这一方法能在多大程度上防止由于精细的作物轮作所产生的土壤退化。
the influence of various factors, including lowest pressure of the vacuum chamber, water content and size of the sample in three states of solid, lidquid or syrup, on cooling rate and on final sample temperature in self-freezing by vacuum pumping, was studied 摘要以液态、浆态和固态三种不同类型的物料为对象,通过大量实验研究了真空室压力、物料含水量和尺寸对抽真空自冻结的降温速率和对冻结最终温度的影响规律。
the influence of the array chamber, carrier gas flux and sample temperature on the performance of the system was discussed in the identification of different brands of cigarettes . while in the detection of alcohol with gasoline interference, the methods of signal preprocessing showed great effects . and at the end, suggestions were made on the optimization of the system construction and measurement strategies, which advanced towards portable en systems 在卷烟鉴别问题中详细研究了测试气室、载气流量、样本温度等实验条件对系统的识别性能的影响;在有汽油干扰的酒精检测问题中,考察了数据预处理方法对于识别结果的影响,并提出了系统改进的建议。
