Via comprehensive computations, the possibilities of vinylidene and allene intermediates were excluded, and the reaction mechanism was found to contain the following three steps:(1) gold-catalyzed cyclization to give the cyclic intermediate,(2) the cyclic intermediate undergoing a 1,3-H migration to give a more stable intermediate, with the assistance of water-cluster,(3) finially, the 1,2-H or 1,2-silyl migration occuring for generation of the observed product.

通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。

Anthocyanidin extract in methanol showed 3 absorption peaks, at 270, 340 and 520 nm, in the UV-vis spectrum, with bathochromic and hypsochromic shift with methanol+AlCl3 and methanol+AlCl3+HCl, respectively; the ratio of the absorbance at 440 nm to that at 520 nm was 0.29. No fluorescence occurred under UV irradiance, and 5 absorption peaks occurred at 270 nm after HPLC. Five molecular ion peaks occurred on MS: 595, 381, 611, 587 and 571, respectively, and monosaccharides in the extract were identified as rhamuose and glucose on HPLC.

一品红花色素的甲醇溶液分别在270、340 和520 nm 处有 3 个吸收峰；在 440 nm 吸光度与可见光最大吸收波长 520 nm 吸光度的比值为0.29；花色素的甲醇溶液中加入AlCl3后发生红移，再加入HCl后发生蓝移；色素溶液在紫外光下无荧光；色素样品经液相色谱分离后在 270 nm检测有 5 个比较明显的吸收峰；质谱中得到 595、611、381、571 和 589 等对应的分子离子峰；花色素酸解液高效液相色谱图谱和鼠李糖、葡萄糖的出峰时间一致。

"A reduction in the heart rate ariability has been reported in seeral cardiological and non-cardiological diseases," said Banks."If our finding is sustained by a larger group and further analysis, it may suggest why short sleep duration is associated with a heightened risk of cardioascular disease and mortality."

邦斯说：心率变异性降低曾经被报告发生在数例心脏病和非心脏病患者身上，假如我们的发现再持续一个更大的组进行而来进一步的分析，有可能提示短期睡眠是发生心血管疾病和死亡的高风险的原因。

In fact Biodynamic Craniosacral Therapy is so gentle that some people think nothing is happening. But that "nothing" is the key. When we stop trying to do something, stop trying to control ourselves, perfect ourselves, fix ourselves, when we stop, we can enter the primordial stillness and silence of the body′s deep wisdom. In that dynamic stillness, the fixed patterns of sickness, trauma, distress, alienation and suffering can be released and the body/heart/mind can reorient itself toward the powerful health and natural bliss of our deepest self.

事实上头荐骨疗法是如此地温和，以至于一些人认为什么事都没发生，但&什么事都没发生&是个关键，当我们停止去做什么的企图，停止努力去控制我们自己，使自己完美和修理自己，当我们停下来时，我们就能够进入身体深层智慧的根本静止和宁静之中，在这种有活力的静止中，固着的疾病模式，创伤，不幸，疏离和受苦会被释放，身心灵会再调整自身朝向强大的健康和我们最深自我的自然狂喜。

Once you know the true meaning of achievement and elimination, even the most misfortunate thing happens to you, you would throw off the original benefit and function immediately, and view it at other angle, think it in a new way and realize it is a new environment, and then, you would find the new and different value.

有了这样的体认之后，就是再倒楣的事情发生在你的身上你也无所谓了。因为，如果你能换个角度去看待它，将原有的好处与功能皆抛弃掉，再以新的思维、新的角度来观察、来肯定新的环境及机遇；那麼，你必能发现到老子所说的，新的、不同的价值了。

Objective To use an ischemical reperfusion injury rat model by pulsinelli-4-VO andobserve the changes of the expression of Glu, N-methy-D-asparagic acidreceptor subunits NR_1 and NR_(2B) and ability of learning and memory after procerebrum ischemic reperfusion injury, and approach the pathogenesy of learning andmemory disorder induced by ischemic reperfusion injury, and the intervention ofginsenoside Rg_2 on the learning and memory disorder after procerebrumischemic reperfusion injury.

目的利用pulsinelli四血管法体建立脑缺血／再灌注损伤模型，观察前脑缺血损伤后谷氨酸、N-甲基-D-天门冬氨酸受体亚单位NR_1、NR_(2B)表达的变化及学习记忆的改变，从兴奋性氨基酸的兴奋毒作用尤其是其受体的表达方面探讨脑缺血／再灌注损伤引起的学习记忆功能障碍的发生机制，并观察人参皂苷Rg_2对脑缺血缺氧损伤引起的学习记忆障碍的干预机制。

We should point out again that in any given year a company writing long-tail insurance (coverages giving rise to claims that are often settled many years after the loss-causing event takes place) can report almost any earnings that the CEO desires. Too often the industry has reported wildly inaccurate figures by misstating liabilities. Most of the mistakes have been innocent. Sometimes, however, they have been intentional, their object being to fool investors and regulators. Auditors and actuaries have usually failed to prevent both varieties of misstatement.

我们必须再一次指出，一个签发长尾型保险的公司(保单理赔范围通常在损失事件发生好几年后才会理赔的保单)，其经理几乎可以随心所欲的操控其短期的盈余数字，这行业因为负债错估而导致报表数字不真实可说是司空见惯的事，大部分的错误或许都是出于无心，但有时也有可能是故意的，其目的无非是想要误导投资人以及主管机关，而会计师以及精算师往往无法预防此类的事件发生。

To illustrate, the XYZ insurance company might have last year bought a policy obligating us to pay the first $1 billion of losses and loss adjustment expenses from events that happened in, say, 1995 and earlier years.

另外还有一个影响更大的因素，也是你在别的地方找不到的，那就是有些公司想要把过去发生但却不确定的损失解决掉，简单的说，有家 XYZ 保险公司在去年向我们买了一张保单，约定我们必须支付头 10 亿美元的损失再加上以前年度，比如说 1995 年后续的损失调整费用，这些合约的金额有可能相当大，当然不论如何，我们还是会定一个上限，我们在 2000 年签了几件这类的合约，到了 2001 年也会再签下几件。

December 10th, I began now to think my Cave or Vault finished, when on a Sudden,(it seems I had made it too large) a great Quantity of Earth fell down from the Top and one Side, so much, that in short it frighted me, and not without Reason too; for if I had been under it I had never wanted a Grave-Digger: Upon this Disaster I had a great deal of Work to do over again; for I had the loose Earth to carry out; and which was of more Importance, I had the Seiling to prop up, so that I might be sure no more would come down.

十二月十日我本以为挖洞的工程已大功告成，可突然发生了塌方。也许我把洞挖得太大了，大量的泥土从顶上和一旁的岩壁上塌下来，落下的泥土之多，简直把我吓坏了。我这般惊恐，当然不是没有理由的。要是塌方时我正在洞内，那我肯定用不着掘墓人了。这次灾祸一发生，我又有许多工作要做了。我不但要把落下来的松土运出去，还安装了天花板，下面用柱子支撑起来，免得再出现塌方的灾难。

Recently, President of KNT party Mr. Ma Yingjiu made a visit to the United Kingdom. And it is reported that his visit had been obstructed by the diplomatic personnel from the mainland. And there are contrimiations of such an incident globally. A lot of people with visions say that the mainland and Taiwan should put an end to their practice of diplomatic war. On the contrary, they should have a diplomatic truce. What's your view on this?

最近台湾的中国国民党主席马英九先生在英国访问的时候，在这个过程中与中共当地的人员有一些冲突，遭到一些阻挠，类似的事情在不断地发生，两岸有识之士在不断地呼吁两岸之间不要再僵处，不要再在国际上做这样的事情，最好能够&外交&休兵，对这样的事情您是怎么看的？
