METHODS To determine the limit content of CMX bacterial endotoxin and To measure the maximal undisturbed concentration disturbed test. 方法确定CMX的细菌内毒素限值,并进行干扰试验测定。
An Experimental investigation of the characteristics of viscosity for oil-water mixtures disturbed by gas injecting with different input ratios flowing in horizontal pipes was conducted using local sampling method. No. 46 mechanical oil, tap water and air were used as the test fluids. 采用局部即时取样方法对水平管内油气水三相流动情况下各种混合比例的复杂混合物的流动粘度进行了实验研究,实验工质采用46号机械油、自来水和空气。
Result: The test had no disturbed by sample solution of 1: 2 which was the same as rabbit test. 结果:1:2样品溶液无干扰作用,与家兔法结果一致。
The article establishes a fuzzy decision pattern of multilayer and multi-objective system, and chooses the optimal observation well in the pumping test of disturbed wells and the optimal pumping well in the pumping test of single wells by this system quantitatively. 该文通过建立多层次多目标系统模糊决策模型,分别定量的优选了干扰井群抽水试验的最佳观测孔和单井抽水试验的最佳抽水试验单井;
It is required in the design that aquifer medium and flow field were essentially not disturbed when frame was inserted into test zone. 设计要求该框架在其插入实验区时基本不扰动含水介质,也不扰动地下水流场。
Methods: Taking moisture absorption rate as measure index, various facters effected the moisture absorption rate, and the optimal coating process can be selected with well disturbed uniform design and computer analog test. 方法:用吸湿率为考察指标,研究了包衣过程中,影响包衣颗粒吸湿率的各因素,用均匀设计和计算机模拟实验选择了最优包衣工艺。
Aimed at rheologic problems under unloading of soft soils, a three-dimensional rheology constitutive model considering unloading and disturbance were established based on disturbed state concept theory and results of laboratory test. 本文针对软土卸荷流变问题,采用扰动状态理论,从室内卸荷试验入手,建立了从一维到三维的卸荷流变本构模型。
