但总产量仍不断增加，据此回答1—2题。 1．传统稻米产区农业生产最关键是要改变 [ ] A．精耕细作的传统经验 B．人均耕地少，水热资源未充分合理利用 C．现代化生产技术水平较低，劳动生产率不高 D．农业资源的人均占有量在世界上属于低水平 2．在季风区内，每年对水稻生产威胁最大的因素是 [ ] A...
Li-ion batteries are used to store energy harvested from photovoltaics. However, battery use is sporadic and standard diagnostic methods cannot be applied. Here, the authors propose a methodology for diagnosing photovoltaics-connected Li-ion batteries that use trained machine learning algorithms. ...
These systems struggle to compete with animals that excel through their agile and effortless motion in natural environments. We propose a bio-inspired musculoskeletal leg architecture driven by antagonistic pairs of electrohydraulic artificial muscles. Our leg is mounted on a boom arm and can ...
As velocity of flow increases, a condition is eventually reached at which rectilinear laminar flow is no longer stable, and a transition occurs to an alternate mode of motion that always involves complex particle paths. This motion may be of a multidimensional secondary laminar form, or it may ...
It is important to know the costs associated with the operation of a production machine so that these can be taken into account in the machine design. For example, the SinaSave software application can help you to calculate how soon you will recoup your investment if you purchase an energy-...
Zhu et al. (2010) studied the heat transfer performance of a wall with high thermal mass in zero-energy buildings. Their results indicate that it is most suitable to be applied in areas with large temperature differences between the day and night as well as between indoors and outdoors. In...
The word “chakra” is Sanskrit for “wheel.”And that’s exactly what it is: wheels of energy in the body, with the seven main ones stacked like a ladder from the base of your spine to the crown of your head. When they spin in harmony, your whole system is harmonious. ...
Kinetic or potential energy associated with the motion or position of an object gravity A force of attraction between objects that is due to their masses. gravitational energy Potential energy that depends on the height of an object electric energy the energy that an electric current carries scienti...
From there it either oscillates back and forth between the two (a) or the excitation amplitude is so large that we find that the motion is no longer oscillatory, with the excitation instead travelling only in one direction (b). Similar to Fig. 2, n(x) is the normalized line density ...
