Generally, hand crafted eyewear can be made from two type of materials, e.g. Acetate and Celluloid. Nowadays, almost all European and American manufacturer use acetate for eyewear production. It is because of the limitations of celluloid. Such as low plasticity, difficult in dyeing, long period for material maturation and highly flammable. Accordingly, only Japanese manufacturers insist to use celluloid as the building block for eyewear.

一般来说，手造眼镜可以用两种材料制成，第一种是醋酸纤维，第二种是赛璐珞，现时差不多全部欧美国家都采用，因为赛璐珞有著许多缺点，例如：可塑性低，不易染色，待料时间长，与及高易燃性，所以在60年代欧美眼镜制造商全面禁用此材料而改为使用之后，全世界就只剩日本是唯一还持续使用赛璐珞材料制造眼镜的国家。

When investors are in the treasury secondary market, they have to undertake two kinds of risks: the first one is yield risk, that is, return of investment is lower than inflation rate. This risk can be depicted as the deviation between the ROI and the inflation rate. Secondly, fluctuation risk in the treasury secondary market, that is, the uncertain fluctuation risk may be bullish or bearish in the treasury market.This risk can be depicted as the square deviation of the treasury price in the secondary market.

在国债现货二级市场上的投资者，要承担的风险主要有两种：第一种风险是收益率风险，也就是投资收益率可能低于通货膨胀率的风险，这种风险可以用与通货膨胀率相比较的差值的大小来描述；第二种风险是二级市场价格波动性风险，也就是市场价格上、下波动的不确定性风险，这种风险可以用二级市场价格的标准差来描述。

Results showed a high-purity and a good-integrity DNA can be obtained from the preserved fresh leaves of Camellia azalea, using the methods of modified CTAB and SDS subarea. The DNA extracting quality from the leaves preserved with silica gel by the methods of modified CTAB and SDS subarea is high, which is the same as from the leaves preserved at the -200C and liquid nitrogen, So these preserving methods are suitable for the fresh leaves of Camellia azalea, including for it from distant place.

结果表明，改进的CTAB和SDS区室法都适合杜鹃红山茶基因组DNA的提取，都能提取到完整性较好、纯度较高的基因组DNA，且在采用的-200C、液氮、硅胶脱水干燥3种方法保存样品中，硅胶脱水干燥法保存的样品与其它几种方法保存的样品一样，提取获得了高质量DNA，为远距离采样提取杜鹃红山茶DNA提供了一种较好的鲜叶保存方法。

One element may be substituted for another in a compound, the substituted element being set free.

在一种化合物里，一种元素可以取代另一种元素，而被取代的元素就被释出。

Beforetime the state of having nothing is the first style. When we have abundant things, it becomes the second one. Then there're more spare times, and maybe this is the third one.
