Yet many of us fight like giants to guard ourselves from intimacy, boxing up our hearts in steel-hard false beliefs.

可是，我们当中有许多人就正在像巨人那样&捍卫着&自己不受&亲密&伤害，把心灵装入一层层无比坚硬的&虚假信念&的匣子里。

How unlikely, that a short-lived biped on a two-bit planet should be able to gauge the speed of light, lay bare the structure of an atom, or calculate the gravitational tug of a black hole.

想想这一切是多么地不可思议：在一个不起眼的星球上，生存着一种拥有短暂生命的两足生物，然而，正是这些微不足道的小生物，不但测量出了光速，而且把原子层层剥开，还计算出了黑洞的引力。

The results showed: when TLC solvent system was: chloroform - methanol - diethyl amine = 90:9:1, alkaloids from lotus leaves were well isolated, and five components were isolated and identified by spraying Dragendorff reagent. The optimal conditions of HPLC solvent system were: methanol- water - diethyl amine = 75:25:0.0125. Under the conditions, components of alkaloids from lotus leaves were separated very well, and ideal RP-HPLC peaks were obtained.5、Methods of High Speed Counter Current Chromatography and preparative High Performance Liquid Chromatography applied to identify and purify alkaloids from lotus leaves were set up. When solvent system of HSCCC was: chloroform - methanol - water (pH=4.00)= 4:3:2, speed of chromatogram was 700rpm, flow speed of the mobile phase was 2mL/min, four pure components relatively were attained by isolation and purification.

结果表明：薄层层析溶剂系统为氯仿：甲醇：二乙胺=90：9：1，使荷叶中的生物碱达到了较好的分离效果，并用改良的碘化铋钾试剂喷雾显色，共分离鉴别出了5种荷叶生物碱；分析型HPLC分析检测的较优溶剂系统为甲醇：水：二乙胺=75：25：0.0125，使荷叶生物碱的各个组分达到了基线分离，并获得了较好的峰形。5、建立了高速逆流色谱和制备型HPLC技术分离纯化荷叶生物碱的具体方法。H(来源：ABC46论文网www.abclunwen.com)SCCC法在溶剂系统为氯仿：甲醇：pH4.00的水=4：3：2，色谱仪转速为700rpm，流动相流速为2mL／min的条件下，分离纯化得到了4个纯度较高的化合物。

Objectives:To introduce the author's experiences in bioassay of platelet activating factor with thin layer chromatographic separation and platelet aggregation method,and to discuss probable problems in the process.

目的：介绍作者应用薄层层析分离和生物测定法测定血小板激活因子的体会，重点讨论分离和测定过程中可能出现的问题及注意事项。

Thin layer chromatography separation and platelet aggregation assay were suitable for the determination of platelet activating factor,the results were satisfactory in case of standardized operation.

薄层层析分离和生物测定的方法适用于血小板激活因子的检测，只要在检测过程中注意操作的合理性与规范性，检测结果就可满意。

""Using technology that allows self-diagnosis followed by self-treatment or home care"是方式状语,其中,"that allows self-diagnosis followed by self-treatment or home care"是定语从句,而"followed by self-treatment or home care"又是修饰"self-diagnosis

的定语。一层层分析后，我们可以理解得很清楚：负起更大的责任是通过利用技术的方式，而这一技术是允许自我诊断的，自我诊断之后跟着的是自我治疗和家庭护理。

This is a not a big music room, a zither lay in the middle of the classroom, the piano and has reddish brown in the sunlight, the right high left low, right headstock proudly a white plum blossom is the sea turtle mosaic formed, the layer layer surrounded by a delicate flower petals, not only Bai gloss, and it seems more texture, next to the line of small characters: Mountain and Flowing Water Seeking aficionados, and written chic Toshihaya, black font with a brown body has become more elegant and classical piano.

这是一间不算大的音乐教室，一架古筝横在教室中间，琴身泛着棕色的光泽，右高左低，右边琴头一朵白梅花傲然绽放，是玳瑁镶嵌而成，层层花瓣簇拥着细嫩的花蕊，不仅白润光泽，而且看起来更有质感，旁边一行小楷：高山流水觅知音，写得潇洒俊逸，黑色的字体配着棕色的琴身更显得优雅古典。

As the years pass and layer on layer of rock fragments pile up, they are squeezed or compacted by the weight of the materials on top of them. Then sediments may be cemented together, forming the sedimentary rocks.

随着时间的流逝，岩石和矿物碎屑一层层地堆积起来，上覆岩屑物质的重量对下伏岩屑产生压实作用，然后沉积物被胶结在一起，最终形成沉积岩。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
