Therefore, the interaction structures with distributed wall losses and attenuating severs were more stability for absolute instability and gyrotron backward oscillations.

藉由引用非线性程式进行磁旋行波放大器稳定分析，结果显示散布式损耗(distributed-losses)的设计对绝对不稳定有明显的抑制作用，而隔离管结构亦具有减短磁旋返波振荡作用长度的效用，因此我们采用兼具隔离管及散布式损耗结构的磁旋行波放大器，同时提升绝对不稳定和磁旋返波振荡的稳定性。

Results of buffeting response rules and the influence of wind-structure interaction on buffeting were found using the method.

Result The results showed that 34 compounds of the volatile oil were identified, which accounted for 90.10% of all. The main chemical compounds were camphene (10.030%), beta-pinene (8.826%), limonene (7.935%), caryophyllene (12.457%). The antibacterial experiments of the volatile oil showed that the volatile oil had antibacterial activities to Staphylococcus aureus, but had no inhibition against Escherichia coil and Rhodotorula glutinis.

The inhibition of coleoptile elongation is alleviated when exogenous auxin was added to the medium under the low concentrations of Cu2+ stress. However, under high concentrations of Cu2+ stress, as the toxicity is so much, exogenous auxin is not available any further.

小麦胚芽鞘的生长只表现为细胞的伸长，原理为生长素作用的结果，外加生长素，发现生长素缓解了重金属铜对胚芽鞘伸长作用的抑制，而在高浓度时，由于毒害太大，所以无效。

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

结果表明：不同黄瓜品种直接不定芽数量诱导存在显著差异，但长度诱导无显著差异；6-苄氨基嘌呤对直接不定芽数量和长度的诱导作用显著，其中4.0mg/L为数量诱导适宜浓度，其出芽率和每外植体出芽数达到最高，分别为100.0%和11.1，0.5mg/L为长度诱导适宜浓度，其平均芽长12.0mm；外植体的大小对直接不定芽数量和长度均具显著影响，随着子叶的增大诱导直接不定芽的数量和长度增加，其中单片完整子叶为最适宜大小，其出芽率、每外植体出芽数和平均芽长分别达到100%、6.7和17.1mm；硝酸银也对直接不定芽数量诱导影响显著，其中2.0mg/L为适宜浓度，出芽率和每外植体出芽数分别达到97.2%和4.2，但对芽长有抑制作用。

The numerical results were proved to be reliable by comparing with some published experimental data. The results show that, when only Coriolis force is in effect by omitting the centrifugal buoyancy force, the flow in the cavity is axi-symmetrically stable, the Coriolis force is a kind of resilience, and does not cause flow unstably.

研究结果表明：在哥氏力的单独作用下轴向通流旋转盘腔内的流动基本上是稳定的三维轴对称结构，即使有轻微的径向或周向振动发生，由于哥氏力是恢复力，对其有抑制作用，因此振动会随着流场的发展逐渐消失。

These results suggested that corm formation could be improved by MJ but suppressed by SHAM through regulating the LOX activity, resulting in carbohydrate accumulation and increase of antioxidant enzymes activities in Gladiolus hybridus .

以上试验结果说明SHAM对唐菖蒲试管结球起抑制作用，而MJ有明显的促进作用，可能通过外施MJ提高了LOX活性及内源MJ含量，调动碳水化合物的积累，增加抗氧化酶的活性，从而对球茎的发生和生长进行调控。

Methodssmear 0.25% croton oil＼acetone ag on the back of kunming mice,and observe the growth condition of papilloma,then record the quantity of tumor-bearing mice and the quantity of tumor in each mice.results20-ginsenoside rh2 prolonged the incubation of tumor, reduced the quantity of tumor-bearing mice and decreased the amount of tumor in each mice.conclusion20ginsenoside rh2 has obvious anti-papilloma effect on the mice skin.
