Contrast is not opposition but the departure point for a fruitful union of chiaroscuro which gives birth to shades of transparent grey, generated by fate, coincidence, random but controlled water cascades.

作为现象世界的一种表现，禅境美所表达的"空"和"无"是对人生绝对意义和绝对真理实在性的一种否认。

Methods: Consult VP diagnosis standard of American psychiatry institute what WHO promulgated, we chose 80 VD sufferer. We adopt study method of random and comfort drug comparison, both blind method to dose and front and bank of oneself chiasma test. We chose MMSE and ADL to evaluate curative effect through comparing Statistic mark before cure and after cure. Results: We had treated 72 VD sufferer on Jiannaoyizhi capsule. In these patients, there are 15 obvious efficiency, 38 efficiency and 19 inefficiency. The total efficiency is 73.61%. It has obvious reform action on cognizing obstacle and behavior.

参照WHO公布的美国精神病学会VD诊断标准入选VD患者80例，采用随机安慰剂对照，双盲给药，自身前后交叉试验的研究法，选择简易智能量表、日常生活自理能力量表于疗程前后统计分值变化进行疗效评估石结果：健脑益智胶囊治疗VD患者72例，显效15例，有效38例，无效19例，总体有效率73.61%，对VD患者的认知障碍和行为均有明显改善作用，其效应明显优于安慰剂(P.05)。

A small gesture of remembrance, a greeting card in Christmas, a random invitation card for a ceremony , calling him on his birthday, letting him know of your promotion, of your childbirth etc will go a long way in nurturing your friendship.

一件小小的纪念品，一张圣诞节问候卡，一张随意的典礼邀请函，他过生日时给他打个电话，告诉他你晋升了，你的生日等等，所有这些举动都会让你们的友谊一直延续下去。

In chapter two, this paper has made and explained operation course, the definition of the security investment fund and net value computing technology of the security investment fund at first; this paper uses time the analytical method of the array to analyse the array of net value of the fund, divide which into secular trend array , season index array , circulation fluctuate index array and random fluctuate index array and analyse them respectively.

在第二章，本文首先对证券投资基金的运作过程、证券投资基金的定义及净值的计算方法作了阐述，随后本文运用时间序列分析方法对基金净值序列进行分析，将其分解为长期趋势序列、季节指数序列、循环波动指数序列和随机波动指数序列并分别对其进行分析。

Tom: You are right, he worked hard all the time.

你是对的。他一直都是努力工作。

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.

把缺点、失败及别人的耻笑等看成是一种常事，当成完善自己的动力，对别人的评价和议论自己心中有主见，做到&有则改之，无则加勉&，不为人言所左右或无所适从。
