While Maimonides and his followers regarded philosophical speculation as the highest duty of man, and even made the immortality of the soul dependent on it; or, speaking more correctly, while immortality meant for them only the highest development of "active intellect" in man, to which only a few attained, the Cabalists taught not only that every man may expect a great deal in the future world, according to his good and pious actions, but even that he is the most important factor in nature in this world.

虽然迈蒙尼德和他的追随者视为投机哲学的最高责任人，甚至作出不朽的灵魂依赖於它，或者更准确地讲，而永生意味著不仅为他们的最高发展"积极的智慧"在人，其中只有少数几个实现， Cabalists教的不仅是每个人可以指望得到了大量的未来世界，根据他的良好的和虔诚的行动，但即使他是最重要的因素的性质在这个世界上。

The spectrum analysis of the air-ultrasonic waveform indicates that when the matcher thickness is calculated at the highest spectrum and the subsequent higher spectrum of the pulse waveform, it can obtain a better result. But all the highest spectrum of the air-ultrasonic waveform moves to the high frequency zone in the experiment, which is a possible important reason that the testing extent of the air-ultrasonic transducer is limited.

It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.
