The experimental results show that: the bigger the grain parameter is, the greater the expansion is and the longer the stabilization period is. The ideal grain parameter scope is 30-100μm and the grain with parameter less than 10μm should be no more than 20% when the grain parameter scope in 10-100μm.

It indicates that compared with the response spectrums of no velocity pulse records, the response spectrums of velocity pulse records have longer maximum number range, as well as bigger numbers at long periods.

The greater the amplitude change of head wave of transverse velocity is, the severer the damage is, the later the arriving time of the first wave hollow and the longer the damaged element will be.

A small cushion clearance with a adequate cushion length can apparently reduce the piston’s bumping speed, while it can’t more apparently reduce the piston’s bumping speed with longer cushion length but extend the shift time.

Now, because of scarcity of the total electric supply and the mismatch of peak and off-peak load, the electric power becomes new trend that the peak load time lasts longer and the off-peak load time get shorter, thus the original direct evaporate ice-on-coil device is not suit to the change of the electric power, so it is necessary to study the coil direct evaporate ice-on-coil device again.

Taking a bath 15 minutes every time per day, if you want a better result, longer time spend in maintaining the health recovery is necessary, half month to a month in general.

The dog-bone steel flange can protect the welds, meanwhile it will be able to result in a longer plastic zone formed in the flange, thus providing greater ductile deformation and more excellent energy dissipation capacity.

Sedimentation of soft soil groundwork in this area has the features of bigger transformation, serious uneven sedimentation and longer stable sedimentary period, and also more influences from geology and climate.

In general, such a tensor product is no longer irreducible.

Overall the pharmacokinetic properties of both isomers were similar in rats, monkeys and humans, with β-isomer exhibiting longer elimination half-life, MRT, volume of distribution and clearance, irrespective of the route of administration.

This means that the resistance calculation based on two-dimensional models can no longer provide sufficiently accurate results.

It is also discovered that the major approaches to artificial intelligence in history, the structuralism, functionalism and behaviorism, can harmoniously be unified within the framework of the mechanism approach and no longer be contradictory.

euphratica leaves exhibited a higher capacity to exclude salt in a longer period of increasing salinity, thus limited salt-induced lipid peroxide and MP, which contributed to membrane integrity maintenance and salt tolerance of P.

Two methods for analyzing caisson-beams are introduced in this paper.One is the well-known method of redundant forces. The author has simplified this methed by using couples of redundant forces to set up a typical equation and pointing out the rule that the matrix of the coefficients of simultaneous linear equations which are organized from the expansion of that typical equation. This method can be easily solvd when the number of unknown redundant forces, or that of equations, is less than 3 or 4; but it will...

Two methods for analyzing caisson-beams are introduced in this paper.One is the well-known method of redundant forces. The author has simplified this methed by using couples of redundant forces to set up a typical equation and pointing out the rule that the matrix of the coefficients of simultaneous linear equations which are organized from the expansion of that typical equation. This method can be easily solvd when the number of unknown redundant forces, or that of equations, is less than 3 or 4; but it will be difficult when the number is more than that. In order to solve this difficulty the author suggests another kind of method of which the essential principle is mentioned in the following.Supposing that the distance between the beams is sufficiently short in comparing with their spans, we can set up a partial differential equation for its deffiection W, as we often do in the theory of elasticity. In this way we can solve it with its boundary conditions of simple supporting by sine series. From this we can easily get the formulas of bending moments, shears and twist moments of each beam by partially differentiating the function of deffiection. The result of the calculation proves that it quite agrees with the method of redundant forces when the distance between beams is no longer than 1/5 of their spans.There are some tables given in this raper for practical use.

This paper describe the analysis of stresses in a building of three spins and thre storeys. For the want of a better hame, we shall call the product of the sum of the shears at the either ends of eads tier of columns and their length the shear moment for that tier or storey. Evidently the sum of moments at ends of all the columns belonging tothe same storey must equal to the shear moment of the same storey. To begin with we assume that the shear moment in each storey separately equals l. Let us take the nth....

This paper describe the analysis of stresses in a building of three spins and thre storeys. For the want of a better hame, we shall call the product of the sum of the shears at the either ends of eads tier of columns and their length the shear moment for that tier or storey. Evidently the sum of moments at ends of all the columns belonging tothe same storey must equal to the shear moment of the same storey. To begin with we assume that the shear moment in each storey separately equals l. Let us take the nth. storey first. A unit shear moment in this storey will induce certain fixed-end moments in the columas, which will be then distributed among the joints at end of the columns belonging to this storey_2 leaving the moments at any other joint alone. Since the block distribution coefficients and carrying over factors to the second joints used for this distribution are calculated for the whole truss, the moments in a number of joints are still unbalanced, at the same time new moments appear at ends of columns of the (n+1) th and(n—l) th. storeys, so that new shear moments are acquired also by these two storeys. On the other hand the shear moment in the nth. storey is no longer equals to 1, but some new value a. this will not matter, the important thing is that we have determined definitely the ratios between this uew shear moment value a and the moments at the ends of the columns belonging to these three storeys and the shear moments in storeys below and above, In order to bring the value of the shear moment in the nth. storey back to l, we divide all these end moments and shear moments by a, the result is a set of new values, which will be called, for convenience, the influence values due to shear moment in the nth. storev.Wben the building truss is being analysed, we multiply the influence values of different storeys by a set of suitable numbers, and put the results in successive rows in a table. The multiplying should be so chosen that the sums of shear moments for saeh storey should equal approximately their actual values. The end moments are then balanced by block distribution. After this distribution the shear moment for each storey will differ from their actual values appreciably7 the difference wiil be then made up by repetition of the above process as'often as required. For the truss under consideration7 the calculations are repeated only once, then the maximum error in values of shear moments is already so low (only 0.075%), a second repetition of the process is quite unnecessary.

Hydration of high alumina cements made by sintering process in rotary kiln is investiga-ted. Under 20℃ curing, the main hydration products of all of the three kinds of cements with successive higher CaO/Al_2O_3 ratios are CAH-(10) (not C_2AH_8) and alumina gel, i. e., they are essentially the same as the hydration products of the cement made by fusion process as generally reported. The hydration products of cement having a lower CaO/Al-2O_3 ratio or a higher CA_2 content are more stable.The formation of more...

Hydration of high alumina cements made by sintering process in rotary kiln is investiga-ted. Under 20℃ curing, the main hydration products of all of the three kinds of cements with successive higher CaO/Al_2O_3 ratios are CAH-(10) (not C_2AH_8) and alumina gel, i. e., they are essentially the same as the hydration products of the cement made by fusion process as generally reported. The hydration products of cement having a lower CaO/Al-2O_3 ratio or a higher CA_2 content are more stable.The formation of more basic hydrated aluminates (i. e., C_2AH_8 or C_3AH_6) and gibbsite of this kind of cement occurs at a higher curing tempera-ture.While the latter subjects to the same curing temperature as the cement of higher CaO/Al_2O_3,its initial products will be stable unless it subjects to a longer curing.Under various curing tempe-ratures, the variation of strength of the three cements can be explained by the difference in stability of the hydration products, cement of higher CaO/Al_2O_3 ratio providing the lowest thermal stability of the hydrated products and decreasing in strength of the paste under higher temperature.
