Owing to the drawbacks of analytical shimming, this paper puts forward the concept of passive numerical shimming for searching a method of compensating Bz'easily to a high level and with a low cost. Based on the magnetic field caused by a magnetic moment, the distribution of moments in a superconducting NMR imaging megnet can be determined through some pseudoinversion algorithm directly from Bz'. The moments are used to compensate Bz'.

无源数值匀场的出发点直接是不均匀磁场的磁场偏差B〓本身；无源数值匀场的基础为磁性材料的磁矩所产生的磁场；由已知B〓，通过某种逆运算，确定磁性材料的磁矩在主磁体中的分布，实施此分布，以磁性材料的磁矩所产生的磁场直接对B〓进行补偿——这便是本文提出的无源数值匀场的概念。

未来全球性气候变暖对我国的种植制度将产生明显的影响，预计我国各地的热量资源将有不同程度的增加，使一年二熟、一年三熟的种植北界有所北移，主要农作物的种植范围、产量、质量都会有所变化。但由于水分变化可能产生的不利影响，使种植制度的变化具有较大的不确定性。

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

结果表明，当激光脉冲宽度远小于被测样品的特征时间时，对于线性吸收来说，其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式，即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下，可用通常的Z-scan法进行非线性折射率及热光系数的测量，所得结论符合以前的实验结果。

The main causes of the vibration in pipeline system are in two respects : The first is the vibrant force of the medium acted on pipeline system,i.e.exciting signal,such as the vibrant force caused by the gas flow at the compressor ′ s inlet and outlet and at the ramified and nodel points as well as the action of pig passing through pipeline bridge,etc.;The second is the response to the exciting signal,which is relating to the characteristics of the pipeline system,i.e.the rigidity,support,quality and equipments of the system besides the waveform of the exciting signal.

管道系统振动的原因主要有两方面，一是介质对管道系统产生的振动力，即激发信号，如气流在压缩机进、出口，分支节点部位产生的振动力，清管器通过管桥时对它的作用等；另一方面是对激发信号的响应，其响应除了和激发信号的波形有关外，还和管道系统本身的特征，即系统的刚度及支撑，质量及其配置等情况有关。

Second, the distributions of the two series are both non-normal, and one series from auction mechanism has peaker mountaintop and fatter tail than the other series from continuous order-driven mechanism.

第二，通过两种交易制度得到的两个股票收益序列的分布都是偏正态的，并且从集合竞价得到的序列比从连续竞价得到的序列尖峰厚尾；第三，集合竞价产生的股票收益比连续竞价产生的股票收益有更大的噪音，对市场有效假说的随机游走形式更大的偏离。

Mechanical environment, as a native survival one, is very complicated and constituted of many different kinds of forces, such as the forces in vitro or between tissues and cells, and the interactive intracellular stress during the process of formation and remodification of cytoskeletons. All these forces regulate bodies' developments and cellular differentiations, which is particularly obvious in bone tissues.

力学环境是自然赋予生命体的一种生存环境，在这个复杂的环境中，生物体外的力、生命运动过程中产生的体内各组织、细胞间的相互作用力及细胞骨架形成和变化时产生的细胞内张力交互作用，构成了一个力学系统，调节着生物体的生长发育和细胞分化，这一点表现在力对骨骼系统的作用上尤为明显。
