31 At the same time, the historical term "technology" in the prehistorical civilization period, ancient civilization period, the axial period and the era of technology and science is carefully explored.

32 It is difficult to pull out the bolt with ordinary socket wrench that can not provide axial tension because of the bolt drilling hole deformation and the collapse of holes.

33 An axial vector may itself enter into a vector product.

34 The program will design or check concrete columns for axial tension, compression and biaxial moments.

35 Constant radial load (constant axial load center), in the load, the bearing can withstand 1 million transfer theory, the basic rating life.

36 There are so many kinds of fans, such as axial flow fan, centrifugal fan and high pressure fan.

37 Measurements included cycloplegic refraction , biometric axial length and optic disc stereo - photographs.

38 The axial skeleton of mutant embryos shows abnormal vertebral fusions in cervical, lumbar and caudal regions.

39 A method of rotation-photograph was suggested by which the Kinoform with axial rotating symmetry was made up, and experimental results of the spherical Kinoform was presented.

40 With increasing riser height, the average solid holdup at various axial locations of the riser decreases and becomes more uniformly distributed along the riser height.

41 Intercrossed dynamic characteristics related to the axis are not equal to zero, which illustrates that the axial of radial-thrust hybrid bearing has a relationship with the radial of it.

42 In 60 intracranial hypertension patients, 21 cases(35%) displayed superior ophthalmic vein in double axial layers continuously and 8 cases(13.3%) showed tortuosity of superior ophthalmic vein.

43 The equations for magnetic-force pump magnet steel axial direction length, circumferential length, and radial thickness were developed after the analyses of the experiment results.

44 The influence of structure axial vibration on the internal ballistics of solid rocket motor was investigated.

45 Higher lateral deformation and Poisson's ratio as well as negative volumetric strain can be reached for higher pore pressure even though axial strain of specimen is lower.

46 An axial symmetrical model is set up for the sealing structure of the platea columniform dewar.

47 The optimization model of fiber dimension of membrane bioreactor is presented by selecting the axial flux distribution coefficient and energy consumption product as objective functions.

48 The axial stress in them produces a clamping force equal to the product of the proof-load stress, reduced by a design factor, and the core area of the bolt or screw.

49 According to experiences in final assembly, factory test and performance test, some adjustment methods are summarized for the axial clearance of single-row tapered roller bearing.

50 When the radial component of the vapour velocity and the axial variation of the vapour temperature were neglected, the error of the sonic limit is within 10 per cent.

51 The model about performance analysis of seal which is 3D is put forward on the basis of lucubration, and hydrokinetics model of static axial symmetry is established.

52 The maximum force increases with the coil axial length increase, given the fixed coil diameters. The acceleration of armature reaches its maximum when the axial length of coils is short is short.

53 A Z - axial moving cylinder is vertically arranged in front of the clamp.

54 February 12, New York - Washington co - axial cable circuits opened for television transmission on an experimental basis.

55 Axial flow type . A standard agitator in low viscosity . The cycling speed is high.
