The optical recording behavior of 1-Azo nickel chelate was performed by adynamic optical recording tester utilizing signals of central frequency 500kHz and 1 ×recording speed under irradiation of 780 nm semiconductor laser. When the writingpower is 7-8 mW, the CNR reaches 45 dB.

采用光盘动态测试仪测定了具有支持盘片、以偶氮染料1-Azo镍螯合物为记录层、反射层的三层结构盘片的光记录性能，用780 nm半导体激光，中心频率500 kHz，1倍速转速，写入频率为7-8 mW时，载噪比为45 dB。

The reunion dinner must be a spread and we must observe important customs such as visiting my parents on the second day of Chinese New Year as well as visiting relatives and friends...the list goes on. This is why I say just two days of public holidays are not enough. Sigh!

守岁'。''时要输光压岁钱或再赢回一倍，要穿新衣新鞋四处拜年，要看超过三部贺岁片或一整套日剧，初二回娘家的习俗当然也不能漏掉……话讲回来，这样一路&过&下来，短短的两天年假，还真是不够用！

After 3800 Death of the World's top math problems -- Ruler as "arbitrary angle trisection, turning round to square, fold the cube, as is 7-gon, as is 9-gon, as are 10 side of the form, as are 13-gon," The world, where people called mathematicians have challenged the "seven problems" Archimedes Newton Gauss, etc., Are hard to understand in the end.

历经3800年世界顶级数学死题——尺规作&任意角三等分、化圆为方、倍立方体、作正七边形、作正九边形、作正十一边形、作正十三边形&，全球，凡称得上数学家的人都曾挑战过这&七大难题&，阿基米德、牛顿、高斯等等，均以不得其解而告终。

Terpenoids are mainly occurred on marine algae, coral, sponge and some fungi by monoterpene, sesquiterpene, diterpene and triterpene. and glycosides with structures of lipid, steroid and terpenoid are distributed to marine algae, sponge, sea cucumber and starfish.

这些新发现的萜类化合物广泛分布于海藻、珊瑚、海绵以及一些海洋真菌等海洋生物中，主要以单萜、倍半萜、二萜、三萜结构型式存在；而糖苷类化合物在海藻、海绵、海参、海星等海洋生物中发现大部分以糖苷脂、甾体糖苷、萜类糖苷型式存在。

Four further single mutants ofN546(N546G,N546D,N546K,N546Δ), three double mutants and a triple mutant were constructed,and toxins were purified by isoelectric precipitation and an AKTA purifier 100 system.When bioassayed against H.armigera using purified toxins,N546ALC_(501.67μg/mLshowed 1.78 times increased toxicity than wide-type Cry1AcLC_(50 2.98μg/mL,and mutant N546D,N546K and N546Δshowed a great loss in toxicity.

对N546进一步突变，获得了突变子N546G、N546D、N546K和删除突变N546Δ及3个双突变和1个三突变，利用等电点沉淀法和AKTApurifier 100系统纯化了毒素蛋白，生测发现N546ALC_(50为1.67μg/mL对棉铃虫毒力比野生型Cry1AcLC_(50为2.98μg/mL提高了1.78倍，而N546D、N546K和N546Δ的毒力则降低了80～90%。

Actually the green light flashes for 20 times and there a triple beep, then, it went off.

其实开了绿灯闪烁的20倍，并有三蜂鸣，然后，它去了。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
