压缩的

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.

目前，在电场计算领域所开展的工作相对较少，而且仅限于传统边界元方法的应用；在计算流体力学领域，近年来虽然一些学者应用边界元法，在解决定常、不可压缩等问题进行了相当深入的研究，获得了若干研究成果，但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解，而未见研究工作的报道。

It is found that the third order method is the best when abridging reflectance from 5 nm to 10 nm, 20 nm or 30 nm intervals, while the direct selection method is the best when abridging reflectance from 10 nm to 20 nm or 30 nm.

从仿真的结果可以看出：若将测量间隔为5 nm的数据压缩成间隔为10 nm、20 nm或30 nm的数据，则采用三阶删节方法误差最小；若将测量间隔为10 nm的数据压缩成间隔为20 nm或30 nm的数据，则直接选取法似乎结果更好一些。

The images you are looking at in the video are "space weather beacon mode" images that are telemetered down nearly continuously: in near-realtime, and are both binned (undersampled spatially, down to 512 x 512 pixels) and heavily, lossily compressed digitally onboard (analogous to the various JPEG compression settings on a digital camera, but much more severe).

你们在视频里面看见的是&太空气候信标式&的影像，它们被连续地用遥测发射器传送着：几乎是以实时的方式进行的，并都被频密地放入了储存器中。（空间上取样不足，缩减为512 x 512像素），数字压缩时造成了损耗，（与在数字相机上进行的各种JPEG格式的压缩情况类似，但更加严重）。

The constitutive relation put forward in this chapter and the experimental result of uniaxial tension of elas-plastic foams coincide well. 6. The experimental result of ceramic foams shows that the mainly way of the deformation of framework was its bending for ceramic foam made by natural indurating.

从泡沫陶瓷压缩实验结果知：用自然硬化工艺生产的泡沫陶瓷的骨架变形以弯曲为主，体现了海绵典型的受力特征，实际上是一种海绵和浆料的混合物；用烧结法生产的泡沫陶瓷的骨架变形主要是脆性断裂；前者压缩性能优于后者：两者方向性不明显。

The companion galaxy's pull would be inducing extra starbirth by compressing gas, jump-starting the process by which stars form.

伴星系的拉力会以压缩气体的方式引发额外的产星活动，气体的压缩正是恒星形成过程的开端。

We also evaluate the performance of JPEG2000 and hardware-software systems by building a simulation environment that off-loads the task of wavelet transform to a co-processor.

另外我们建立了一个测试模拟的环境。经由将JPEG2000影像压缩中的离散小波转换的运算分离出来让辅助处理器来处理，藉此来体验JPEG2000的压缩效能与软硬体共用设计的好处。

The basic theory of remote watching system for an unmanned substation is introduced. The necessity of image compaction in dada transmission, the theory of 2?dimension wavelet transform, and Mallat algorithm are also explained. Based on that, the method for reconstituting the site image with the original picture and the effective area,which is compacted by the wavelet transform and transmitted to dispatch center, is analyzed.

By means of the 3Ds Max and Flash software ,this system reappeared the structure of various automobile parts and their working principle and moving mode,which made the teaching more vividly and lively; Using Goldwave and LAME MP3 Encoder audio-frequency software effectively compressed the system audio media document, so it could reduce the overall system possessive amount; Many kinds of alternately responsible types such as the button,hot spot,text entry and so on,and the function of jumps transfers and link including the hypertext link,goto sentence, navigation icon had been used ingeniously and comprehensivly,which was more helpful to complete successfuly in the interactive design .In order to realize the network publishing of the course soft,source program was optimized on the base of facing to the CD-ROM package.
