Secondly, European option pricing problem is discussed when price of stocks follows geometric Brown motion and return of stocks follows Ornstein-Uhlenbeck process. Using Arbitrage-free principle, we give a partial differential equation with which option price is satisfied and using Fourier inverse transformation, the closed-form solution to European Call option pricing formula is given.

Latest researches in the catalysts for synthesis of carbamate by ammonolysis of dimethyl carbonate;2. Progress in the catalysts for synthesis of carbamates by ammonolysis of dimethyl carbonate;3.4,4′-Methylene diphenyl carbamatewas synthesized by ammonolysis of dimethyl carbonate, a substitute of phosgene, and 4,4′-diaminodiphenyl methane with anhydrous zinc acetate as catalyst.

用碳酸二甲酯代替光气，以4，4′-二氨基二苯基甲烷为原料，在无水醋酸锌催化剂的作用下，经胺解反应合成了4，4′-二苯甲烷二氨基甲酸甲酯；测定了MDC的熔点；采用傅里叶变换红外光谱和氢核磁共振对产品结构进行了表征；考察了反应温度、DMC用量、反应压力、反应时间、催化剂用量对MDC收率的影响。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of popular, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water ,but on rainy days or after rain they seem to swim or be driven away ,and nothing remains to break the surface except the last of the olive –yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

这些数叶大多是杨树叶，如一列列黄色小艇般不停地从那些无风也簌簌的高大树木上落下来，落雨般淅淅沥沥。但是在雨天或雨后，它们却飘得无影无踪，或像被什么赶走了，此时湖上只剩下橄榄黄色的睡莲碎片，在盛夏时，碧绿的莲叶曾像盏盏翡翠玉盘一样把整个湖面盖得密不透风。

Having captured these two kinds of bat with special designed equipment, the Shei-Pa technical specialist Chia-hung Chen said, the Formosan tailless leaf-nosed bat has leaf-shaped nose and paper-cone-liked ears and inhabits usually in caves. Only at a few spots in Yilan, Nantou and Hualian, is it observed. Syuejian, elevation 1879 meters, is its highest inhabitance ever found.

用特殊网具捕获这两种蝙蝠的雪管处技士陈家鸿说，无尾叶鼻蝠鼻部为叶片状，耳朵像纸卷成圆桶状，主要栖息在洞穴，台湾已知分布地点只有宜兰、南投与花莲等少数栖地，海拔1870公尺的雪见是目前分布海拔的最高纪录。

Japonica and 1.3 cm of U.pinnatifida which showed heterosis in growth during the temporarily sea cultivaton. The phenotypic character of F_1 juvenile sporophyte of L.japonica♀×U.pinnatifida♂was similar to that of the female parent, namely, L.japonica which generated no rudiments of the pinnate lobations.

海带♀×裙带菜♂杂交组合的受精率为20-33%，在暂养期间F_1幼孢子体达到2.2 cm，大于海带、裙带菜幼孢子体的1.8 cm和1.1 cm，表现出生长优势；F_1幼孢子体表现出母本海带的性状，无裂叶缺刻雏形的形成。

A root system with all of the branches of approximately equal thickness, as the grasses and other monocots.

须根 Fibrous roots 由粗细相近无主次之分的根组成的根系，如禾草和其它单子叶植物的根。

The two species are similar in stomatal character and in the absence of accessory transfusion tissue, but they are very different in stomatal distribution, pinna venation pattern and pinna marginal shape, presence or absence of mucilage canal, differentiation of palisade and spongy parenchyma, characteristics of girder parenchyma and epidermal anticlinal wall.

两个属在气孔器特征与不具副传输组织方面极为相似，而在气孔的分布、羽片脉序式样与叶缘形态、粘液道的有无、海绵组织与栅栏组织的分化、工字厚壁组织与表皮细胞垂周壁特征方面则有较大的差异。

When the continental crust subducted to a certain depth(~90-110 km), almost no hydrous minerals existed in the plate, and nominally anhydrous minerals(NAMs, such as garnet, pyroxene, quartz) in UHP rocks became the main carriers transporting water into the mantle Garnet and omphacite in UHP eclogites at Shuanghe, Dabieshan have been investigated by Micro-FT-IR The results demonstrate that all garnet and omphacite grairks contain structural water occurring as hydroxyl with the content from 30×10^(-6) to 1860×10^(-6)H2O wt.

大陆深俯冲板块到一定深度后（约90~110km），几乎没有含水矿物存在，超高压岩石中名义上无水矿物成为俯冲板块中水的主要载体，是示踪超高压变质流体的重要途径。对大别山双河地区超高压榴辉岩中的石榴石和绿辉石进行了详细的微区傅立叶变换红外光谱分析。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
