无结果地

It was full of sap, full of leaves, and full of boughs; but now in vain does the busy art of man pretend to vie with nature, by tying that withered bundle of twigs to its sapless trunk; it is now at best but the reverse of what it was, a tree turned upside-down, the branches on the earth, and the root in the air; it is now handled by every dirty wench, condemned to do her drudgery, and, by a capricious kind of fate, destined to make other things clean, and be nasty itself; at length, worn to the stumps in the service of the maids, it is either thrown out of doors or condemned to the last use - of kindling a fire.

如今变了样，却还有人自作聪明，想靠手艺同大自然竞争，拿来一束枯枝捆在它那已无树液的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢向天，成为一株头冲下的树，归在任何干苦活的婆子的手里使用，从此受命运摆布，把别人打扫干净，自己却落得个又脏又臭，而在女仆们手里折腾多次之后，最后只剩下一支根株了，于是被扔出门外，或者作为引火的柴禾烧掉了。

The stealth warplane for the microwave radar usually have complicated structures with the coating of wave absorption. On the base of calculation and modeling of the geometrical structure of the warplane in real size, the HF RCS of the air crafts under two different polarizations in different direction have been calculated with the FDTD. The result shows that the above mentioned stealth warplane have the obvious characterstics of frequency resonance, polarization and the relatively large RCS in HF Band 10-30dBm2, which can be used as the theoretical reference for selection of working frequency for sky wave OTH Radar and it also means that the sky wave OTH radar has good capability of anti-stealth targets quantitatively.

Both IS and NA increased heart rate, while propranolol (Pro, 25#mu#g per min) produced a decrease. Phentolamine (Phen, 25#mu#gper min) had no effect. All these effects were similar in vagotomized as well as in unoperated rats. It was shown that the reversal of the effect of sympathetic nervous system on gastric acid secretion is not due to changes in circulation.

IS和NA增加大鼠心率，心得安(25μg/min)显著地减少它，而酚妥拉明(25ug/min)没有明显的作用；IS， NA、心得安或酚妥拉明对迷走神经完整、VT即刻和三月后的大鼠心率的影响均无差异，表明VT后交感神经系统调节胃酸分泌的作用吃变化并非循环改变的结果。

The background characteristics of the CCD system and the influence of the size of integral box upon measurement results are investigated. The following conclusions can be derived form experimental results:(1) Background is strongly depend upon exposure time and pixel binning,while temperature has an ignorable effect upon it,whether with or without ambient light.(2) A 5%-cut is the minimum value in order to get a reasonable result.
