查询词典 turning point or barrier

From the potential energy profile, it can be predicted that, the dominant channel of this reaction consists of three steps: the two reactants first form a three-membered ring intermediate (INT1) through a barrier-free exothermic reaction of 19.2 kJ/mol; three-membered ring intermediate (INT1) isomerizes to a four-membered ring silylene(P2) via the transition state (TS2) with an energy barrier of 22.8 kJ/mol; four-membered ring silylene(P2) further reacts with ethene(R2) to form a silicic bis-heterocyclic compound (P3), which is also a barrier-free exothermic reaction of 132.2 kJ/mol.

用CCSD//MP2/6-31G*方法研究了单重态二甲基亚烷基硅烯与乙烯生成硅杂双环化合物环加成反应的机理，根据该反应的势能面可以预言，该反应的主反应通道有三步组成：第一步是两反应物（R1， R2）首先生成了一三元环中间体（INT1），它是一无势垒的放热反应，放出的能量为19.2 kJ/mol；第二步是三元环中间体(INT1)经过渡态TS2异构化为了四元环硅烯（P2），其势垒为22.8 kJ/mol；第三步是四元环硅烯（P2）进一步与乙烯(R2)反应生成了硅杂双环化合物（P3），该反应也是一无势垒的放热反应，放出的能量为132.2 kJ/mol。

She is not in the washroom and then stopping, because it is finally his own point of view that he cares about and not hers, and with this firmly in mind, and a light, confident step, such as you might find in the works of Bulwer-Lytton, he enters the space she occupies so prettily and, taking her by the hand, proceeds to tear off the stiff white hospital gown (but no, we cannot have that kind of pornographic merde in this majestic and high-minded sentence, which will probably end up in the Library of Congress)(that was just something that took place inside his consciousness, as he looked at her, and since we know that consciousness is always consciousness of something, she is not entirely without responsibility in the matter) so, then, taking her by the hand, he falls into the stupendous white puree of her abyss, no, I mean rather that he asks her how long it has been since her last visit, and she says a fortnight, and he shudders, and tells her that with a condition like hers (she is an immensely popular soldier, and her troops win all their battles by pretending to be forests, the enemy discovering, at the last moment, that those trees they have eaten their lunch under have eyes and swords)(which reminds me of the performance, in 1845, of Robert-Houdin, called The Fantastic Orange Tree, wherein Robert-Houdin borrowed a lady's handkerchief, rubbed it between his hands and passed it into the center of an egg, after which he passed the egg into the center of a lemon, after which he passed the lemon into the center of an orange, then pressed the orange between his hands, making it smaller and smaller, until only a powder remained, whereupon he asked for a small potted orange tree and sprinkled the powder thereupon, upon which the tree burst into blossom, the blossoms turning into oranges, the oranges turning into butterflies, and the butterflies turning into beautiful young ladies, who then married members of the audience), a condition so damaging to real-time social intercourse of any kind, the best thing she can do is give up, and lay down her arms, and he will lie down in them, and together they will permit themselves a bit of the old slap and tickle, she wearing only her Mr.

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。

Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

This study experimentally examined the heat transfer characteristics of 180-deg turning duct under forced convection cooling, as the internal cooling structure of 180-deg turning duct is widely applied to industrial cooling. While several perforated holes were separately arranged within the 180-deg turning duct, the cold flow of better cooling capability was guided in the first duct into the second duct in advance, so as to reduce the overheating of the second duct and realize uniform cooling of the machine members. In addition, the centrally separated holes could yield extra turbulence against the air current, and the interaction between bypass air current and mainstream may possibly improve the overall heat transfer capability.
