第3周 动能和动能定理；势能定理。

In such system, although the kinetic energy and the potential energy are transforming mutually, but the total mechanical energy is constant.

在这样的系统中，尽管动能和势能在互相转化，但总的机械能恒定。

Mechanical energy (such as kinetic energy, potential energy) exists in the mechanical movement of an object.

机械能存在于物体的机械运动中。

The kinetic energy and the potential energy of the system are converted into each other, but the total energy is a constant.

系统的动能与势能不断地相互转换，但总能量却保持恒定。

But in the case of the "G-line," the energy gets stored in the EM fields connected to the electrons, rather than being stored in the kinetic energy and potential energy of the string.

但在线路案件的"G -"，得到的能量储存在电磁场中的电子连接字符串，而不是被储存在动能的能量和潜力。

In the modified Newtonian mechanics, the law of conservation of momentum and the law of conservation of energy become invalid; instead, the inherent momentum and inherent kinetic energy can be defined to make the law of conservation of inherent momentum and the law of particle inherent kinetic energy valid.

在修改后的牛顿力学中，动量守恒定律和能量守恒定律不再成立，但可以定义固有动量和固有动能，使得质点系固有动量守恒定律和质点固有动能守恒定律成立。

People through nuclear reactions, have been synthesized 17 kinds of atomic number greater than 92 of the transuranic elements, and thousands of The new kinds of radioactive nuclides, and by high-energy and ultra-high energy-ray beam and the interaction of atomic nuclei and found hundreds of kinds of short-lived particles, namely, baryon, meson, lepton, and particle resonance states of these particles has led to a new field of study - the birth of particle physics since the age of .70, nuclear physics has entered a deep development and wide application of new, more mature stage, on the one hand the development of particle acceleration and detection techniques, expanding people's research in nuclear means, the other hand, nuclear technology to serve the national economy, for example, for the development and utilization of nuclear energy to provide more accurate nuclear data; the use of isotope tracer technique diagnosis and treatment of disease; the use of radiation and irradiation preservation of food, irradiation breeding .

人们通过核反应，已经人工合成了17种原子序数大于92的超铀元素和上千种新的放射性核素，并且通过高能和超高能射线束和原子核的相互作用，发现了上百种短寿命粒子、即重子、介子、轻子和共振态粒子，对这些粒子的研究导致了一门新学科——粒子物理学的诞生。70年代以来，核物理进入了纵深发展和广泛应用的新的更成熟的阶段，一方面发展粒子的加速技术和探测技术，扩充人们研究原子核的手段，另一方面将核技术服务于国民经济中，例如，为核能的开发利用提供更为准确的核数据；利用同位素示踪技术诊断和治疗疾病；利用射线及辐照技术保存食品、辐照育种等。

PartⅢThe study of macrography, histology, pathology and apoptosis After the impactive injury of acetabular cartilageObjective To discuss the change of short and long peoriod for the impactive injury of acetabular cartilage by using different energy,the pathological mechanism of chondral injury and the relation between chondrocyte apoptosis and cartilage degeneration. Methods fifty-four New Zealand white rabbits were divided into high energy and low energy groups randomly, of which the two groups which were made through the homemade impactive equipment by impacting the right acetabular cartilage of rabbit at 35cm and 15cm with 0.400kg weight vertically and simulating the mechanism of impactive injury of human acetabular cartilage.
