there was a big rate of increase amplitude of the mesomeric rate, and through x2 assay(P﹤0.01)the statistically significant are azithromycin ? ofloxacin ? roxithromycin , they increased from 18.0% to 37.2% ?

At same time, in above mentioned cells their expression of CD15 had all risen also the expressions had all increased after stimulation of LIF, but among them the cell transfected by Shp-2 had the highest increase amplitude.

Based on the observation data collected by 77 hydrologic and meteorological stations in Xinjiang, the analyzed results show that the air temperature in Xinjiang has increased in recent 50 years, and the average increase amplitude is 0.27 ℃. 10·a -1 . The average annual temperature has obviously increased since 1987 than that before 1986, especially the increase amplitudes are as high as 0.6～1.6 ℃ in the western and northern parts of north Xinjiang and in east Xinjiang.

NO provider\|sodium nitroprusside released NO linearly within 30 hours by measuring the concentration of NO in the culture medium. The average increase amplitude was 4\^25 μmol/L. The optimum concertration to depress hyperplasia of fibroblast was 4～5 μmol/L.

Meanwhile, after treatment with DMA during 100 μmol/L to 150 μmol/L, the increase amplitude of G_0/G_1 phase cells and the decrease amplitude of S+G_2/M cells in HL-60/ADM cells were higher than those in HL-60 cells.

The flexural strength of the composite increases in the heat treatment. When the additives mole ratio Y_2O_3/SiO_2=1/2.5, the increase amplitude is the highest.

The maximum amplitude of increase appeared in Dongfang which was 1.4℃ and the minimum 0.5℃ in Shanhudao, but the increase amplitude in the other stations was varied from 0.7 to 1.3℃.

They were both increased sign ificantly in the two discectomy groups as compared with the control group after operation(P< 0.001),and the increase amplitude and speed was bigger and faster i n the complete anterior extraperitoneal discectomy group than in the partial pos terior discectomy group,but with insignificant difference at postoperative 1,3,5 and 7 days(P >0.05).

A warming jump of mean annual temperature of the region occurred in the 1980s, which had an increase amplitude of 0.9°C.

An abrupt warming of the annual mean temperature occurred in the mid-1980s, which had an increase amplitude of 0.9 °C.

The loess units deposited in different geological periods display a very similar pattern of Rb and Sr distribution while paleosol units exhibit a dramatic increase in the Rb/Sr ratio, ranging from 20% to 120% in increase amplitude.

This paper contains two parts: an exact solution of vibration modes and transverse cigenfrequencies of conical shells is studied first, and then is presented a simplified method or computation for practical uses.Donnell type differential equations with variable coefficients are used. Under the assumption of neglecting the tangential components (tangential to median surface) of inertia force, and taking the solution as the following type:an uncoupled equation for solving functions of transverse vibration modes is deduced after using some differentia! operators, as the following:Other two equations, showing the relations between U(x) and W(x), and V(x) and W (x) respectively areliquation (2; gives power-series solutions for W(x), liaving a unperiodic osoillating character and rapidly increasing amplitude, so are the solutions of U(x) and V(x). Unfortunately, the convergence of this series solution is poor, so that limits its practical applications.In order to reduce the computing works, a simplified method is recommended. The physical conception of this method is illustrated as following: Cutting one element from the shell arbitrarily, we shall use a physical model to represent this element (see fig- 2) When vibrating, the elastic restoring effects due to membrane extensional forces and bending (and twisting) moments are looked as two springs in parallel as fig. 2, while the element is the mass m. Then this element of shell is equivalent to the parallel springs system with single degree of freedom, and the whole shell can be represented by the sum of infinite systems of this single type, where the stiffness of springs are functions of the co-ordinates. It is known, that the eigenfrequency of the parallel springs system isThis relation shows us to calculate the eigenfrequencies of conical and cylindrical shells(and other shells) by superposing the results which are obtained from membrane theoryand pure bending theory respectively, i.e., the result w1 is solved by using the following equation :together with cqu. (3) and (4), while the result w2 is obtained by solving the equation:Ihe answer can then be calculated, according the relation w2 = w12 + w22.The analytical method presented in this paper can be used for shells with arbitrary conical angle a and various boundary conditions (the conditions at the vertex point of complete conical shell is discussed).

The electroencephalographic changes during audiogenic seizures have been studied with chronically implanted electrodes in seizure-inclined albino rats under unrestrained and restrained conditions, It has been noted that the patterns of electroencephalogram during seizures varied with the number of seizure trials. There was no apparent epileptic discharge during the first 2—3 seizure trials. Sharp negative spikes with increasing amplitude could be recorded after a few seizure trials from the temporal region on one side at first and on both sides later on. The frequency of the spikes was usually 10—12/sec for a brief period immediately after the onset of the epileptic discharges, and then dropped suddenly to 2—3/sec, continuing at that frequency until the discharges stopped all together. As the number of the seizure trials increased, the epileptic discharges began to spread to the fronto-parietal regions of both sides. At the advanced stage of development, the epileptiform discharges tended to assume the spike-and-wave pattern. The electroencephalographic abnormalities bore no necessary relations to the muscular activities, since they could also be observed in animals paralyzed with succinylcholine or d-tubocurarine.

The conditions under which hard bubbles form in the process of gererating bubbles by a low frequency pulse field were experimentally studied. It was found that the percentage P of hard bubbles decreases quickly with increasing amplitude Hp of the bias pulse field. There was evidence for the existence of a critical value Hpo, such that when Hp ≥ Hpo, all bubbles generated were soft ones.
