无法研究的

In addition we also make research on the residual curve velocity analysis and find that its application is not good and the efficiency is iow. The reasons is that the hypothesis is rigid and it is a local optimizing method.

本文还对目前实用性较强的剩余曲率速度分析方法进行了研究，指出该类方法的应用效果不佳和效率较低的原因在于，理论假设过多，与叠前深度偏移的初衷相违，同时该类方法是单点速度分析，是一局部优化方法，而无法解决具有强烈横向速度变化以及地下构造倾角较大的地震速度建模问题。

Japanese contemporary art has gradually taken on an academic identity since Murakami Takashi's concept of "Superflat" and renowned curator Matsui Midori's "Micropop" were raised. Although these two discourses are insufficient to cover all contemporary art in Japan today, they provide a research direction for over 60 percent of the market for those interested in observing and collecting Japanese contemporary art.

日本的当代艺术在村上隆提出Super Flat 及著名策展人Matsui Midori提出Micropop等概念之后，渐渐的形成了一个可被辨识的学术面貌，虽然这二种论述并无法涵盖今日日本当代艺术的全景，但是却也提供了有兴趣观察及收藏日本当代艺术市场的人们一个可覆盖6成以上的研究方向。

Genetic dissection of QTLs for yield traits were further conducted for the genomic regions harboring Pi25. It was found that two or more linked QTLs for yield traits were located in this region, and they had effects on each of the 6 yield traits studied. It remains unclear that the genetic drag between Pi25 and yield QTLs was solely resulted from unfavorable linkages, or partially ascribed to pleiotropism of Pi25.

应用2期2重复的小区产量性状鉴定试验，进一步剖析产量性状QTL，发现Pi25两侧区间影响所有6个产量性状，且该区间存在2个以上控制产量性状的不同基因座，但尚无法判定研究群体存在的遗传累赘是全部源于抗病基因与产量性状QTL的不利连锁，还是部分源于Pi25的一因多效。

I believe that each of these great inventions—language, the family,the use of tools, government, science, art, and philosophy—has thequality of so combining the potentialities of every human temperament,that each can be learned and perpetuated by any group of human beings,regardless of race, and regardless of the type of civilization withinwhich their progenitors lived; so that a newborn infant from the mostprimitive tribe in New Guinea is as intrinsically capable of graduationfrom Harvard, or writing a sonnet, or inventing a new form of radar asan infant born on Beacon Hill.

过去，孩子们通常会玩这样的游戏——突然指着一个人说："你是干什么的？"有些人会回答："我是一个人。"或回答是哪国人，或是哪个宗教的信徒。当新一代的孩子这样问我时，我答道："我是一个人类学家。"人类学是对人类所有生活方式的研究，需要一个人将全部的精力与时间都投入其中。所以，在谈论信仰时，我无法将自己作为一个人的信仰与作为一个人类学家的信仰区分开来。

With the rapid development of Internet, the Web has become a shared resource of abundant biological information.

随着互联网的飞速发展，Web已经发展成为一个巨大的、分布和共享的信息资源，但目前Web文档多数以半结构化的HTML形式发布数据，这样使得研究人员无法直接利用Web上的海量信息。

In accordance with chaotic essence of speech signals , syllable segmentation in continuous speech is researched by fractal theory . an approach of syllable segmentation using variance fractal dimension is proposed , its performance is analyzed in detail . the method can discriminate between voiced and unvoiced , between surd and sonant , but it can hardly discriminate between sonant

本文根据语音信号的混沌本质，利用分形理论研究了汉语连续语音中的音节分割问题，提出了基于方差分形维数的音节分割方法，并详细分析了该方法的性能，它能很好地解决了无声与有声、浊音与清音间的分割问题，但很难解决浊音间的分割问题，当浊音相连且过渡段较短时，该方法无法实现它们之间的分割。

We found that Efron and Thisted's estimates tend to be less stable and slow in convergence. On the other hand, the estimates of Jackknife, Bootstrap, and Chao are likely to be over-biased.

研究发现Efron and Thisted的模型的估计量容易呈现不稳定的震荡，可能会有无法收歛的问题；而Bootstrap、Jackknife与Chao(1992)则会有高估母体种类数的现象。

The frame adopted for this survey was the telephone listings for the Taiwan Area. In order to avoid being unable to select those residences with unlisted telephone numbers, we first took a systematic random sample of telephone numbers, and then replaced the last digit with a random number. Respondents were chosen from within the selected household according to a set intra-household sampling procedure. The target for this survey was 1200 successful interviews.

本研究以台湾地区住宅电话簿作为抽样的母体清册，为避免未在电话号码簿上登记的用户无法被抽中进行访问的情形，抽样时首先依系统抽样的原则抽出某一电话号码，再以随机乱数取代此号码的尾数，作为访问的样本户，访问时再由访员依户中抽样的原则，抽出应受访的对象进行访问。

Such research is usually impossible because scientists don't have the data necessary to compare present understory plants with those of the past.

进行这样的研究通常是不可能的，因为科学家们不具备必要的资料，无法将目前的林下植物跟以往的林下植物进行对比。

Aimed at the problem that the traditional support vector machine cannot adapt itself to text database updating continuously from time to time, a text categorization algorithm with increment al SVM was presented after analyzing the KKT qualification of newly added text sets and thoroughly investigating the variation of support vector set due to text addition.

针对传统SVM无法适应文本数据库随着时间不断更新的问题，通过对新增文本集的KKT条件的分析，研究了加入新增文本集后支持向量集的变化，提出了使用增量SVM进行文本分类的算法，并通过实验验证了通过该算法得到的分类器和传统分类器有着相似的分类能力和泛化能力

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
