In this study, an experiment is executed to clarify the basic behavior of the Outer-Shell-Driven Shield. The results show that the cutter torque of the outer-shell driven shield is smaller than that of a circular face shield and that the outer-shell-driven shield has good characteristics in...
In the experiment, six single fractured sandstone samples, divided into three groups by different grain sizes, were adopted for high-precision fluid flow tests under a variety of confining stresses. Firstly, to obtain the three-dimensional distribution of fracture morphology for each sample, we ...
The middle of the lever is a movable rigid support that can be moved left and right, and the magnification is different for different locations. The magnification chosen for this experiment was calculated to be approximately 34.02 times. (2) Data monitoring system The data monitoring system uses...
The over-all plan of the experiment is to start with a heterogeneous group of reward rats and to give several behavioral tests which will differentiate ... GH Bower,NE Miller - 《Journal of Comparative & Physiological Psychology》 被引量: 201发表: 1959年 Differentiating early-onset persistent ...
Through the combination of numerical simulation and experiment, it was found that the polymer jets of different materials all showed a certain degree of expansion, but due to the difference of material properties, the expansion diameter and head densification degree of the jet were different. The ...
relates to the inner guardian the Stoics referred to as adaimon. With those concepts in mind, we are ready to continue with Marcus’ list of characteristics of a good person. When Marcus reminds himself not to defile hisdaimon, he notes the good person will exhibit the characteristic of: ...
of cumulative lixiviating rate and cumulative lixiviating intensity are Cr,Mn,Co,Ni and Zn,and that with the lowest ones is Fe.The good effect is obtained using nonlinear function to fit the leaching concentration of heavy metals.The correlative coefficients of the fitting function are better ...
Written informed consent was obtained from all participants, which was approved by an Institutional Review Board of each participating facility. The Access AMH performances were evaluated using routine serum or lithium heparin plasma samples. The method comparison experiment was carried out using unused ...
The paper reviews the properties of cement composites reinforced with short fibres. The effect of natural fibres was investigated: cotton, sisal, jute, ramie, bamboo, and synthetic fibres: polymer and polypropylene. It was noticed that the fibres change
Notably, this structure provides a short transport channel for the electron and ion transport, thereby imparting a good electrical conductivity and low electrical resistance to the entire electrode34. Additionally, the three-dimensional grid structure has good number of voids, which can effectively ...
