Ultrasound and scintigraphy are non-invasive methods used to detect urinary extravasation. Reconstructed CT ureteropyelography has also been employed for the detection of urinary extravasation after renal transplantation. MRI imaging can show the renal function of the transplanted kidney and the extravasation. MRI is an effective non-invasive alternative for the diagnosis of urinary extravasation after renal transplantation especially when ultrasound and scintigraphy are inconclusive.

超音波及核子医学检查是诊断肾脏移植后尿液外漏的非侵袭性的方法，MRI 可以明确的侦测尿液外漏，而且可以知道移植的肾脏是否有功能，这能决定是否需要及是否值得再一次手术，所以MRI 是另一个可以有效且非侵袭性检查，在超音波及核子医学检查没有明确诊断时，可以帮助诊断。

The navies of many countries include nuclear-powered warships; almost half of U.S.

许多国家的海军有核子动力舰艇，美国几乎有一半的战舰使用核子动力。

Three types of interactions in nuclear collisions—preliminary nucleon-nucleon pro cesses, intranuclear cascade and interactions between secondaries— are investigeted in a union hydrodynamic framework.

将核—核碰撞中的三种相互作用：初级核子—核子过程、核内级联效应以及次级粒子之间的相互作用统一用流体力学处理。

In the last half century, many theoretical and experimental envidences confirmed the existence of quarks without doubt, however, these experiments showed that quarks only exist inside hadrons and we will never find free quark.

近半个世纪的理论和实验研究无可争辩地证实了核子等强子内存在夸克，不过这些夸克只存在于核子等强子内而不能作为自由夸克存在。

On the other hand, the imaginary part of our potential between kaon and nucleus is similar to that between nucleon and nucleus, but the real part of the potential between kaon and nucleus is much deeper and narrower in radial distribution.

另外，与核子-核势相比较，对于虚部势，K核的WoodsSaxon势与核子-核的很相似，但是对于实部，K核势要更深更窄一些。

Article 11 The proprietor of a nuclear installation must acquire the legal right to exclusive use of the zone except for highways, railways and seaways.

第11条核子设施经营人，对禁建区内土地，除公路、铁路、水路外，应在核子设施预定使用期间内，依法取得使用权。

During a nuclear accident, all the highways railways and seaways that cross through the exclusion zone must be blockaded immediately in order to control the nuclear accident and dispersal.

核子事故发生时，对於通过禁建区之公路、铁路或水路得随时封锁，以便专供处理核子事故及疏散之用外，并应立即通知当地治安机关。

By consideringthe formation time of secondary particles we have developed theparticipant nucleon model incorperating the secondary collisionsnaturally and calculated the increase of the 〓 ratio caused by thesecondary collisions of pions with target nucleons.

本论文另一研究工作就是通过考虑次级粒子的形成时间，自然地将参加者核子模型发展成为包括次级碰撞过程的模型，并根据此物理图象，计算了高能原子核一原子核碰撞过程中由于π介子与核子的次级碰撞过程而导致的次级粒子中的K+/π+比例的增加。

By examining the type and momentum of the displaced nucleons, the authors determined that most of the pairs were mixed neutron-proton pairs.

通过检测分离出的核子的类型和动量，笔者得出结论：绝大部分的核子对是由中子和质子混合组成。

The excluded volume effect of nucleons is studied by calculating the first order self-energy of the nucleon in nuclear matter with perturbation theory as the volume of nucleons is considered, then its influence on the equation of state of nuclear matter is discussed.

在相对论平均场框架内计算了核子体积对核物质中核子自能的一级微扰修正，并进一步讨论了这种修正对核物质状态方程的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
