极少的

The biostratigraphy of this paper is mainly achieved at these two kinds of fossils. The abundance and the diversity of plant fossils are very different across the TPTB stratigraphic set in western Guizhou and eastern Yunnan.

植物化石方面，在研究区两剖面上的界线层组上、下，植物化石的丰度和分异度均存在极大的差异，晚二叠世植物大化石的属种多，化石含量也十分丰富，早三叠世属种单调（或无完整的植物大化石出现），化石含量也极少。

Because hypocretin-1 levels were not significantly influenced by the use of psychotropic medications or by the presence of other sleep disorders, this testing "may therefore be most useful in cataplectic patients in whom treatment has been initiated, and/or when other sleep disorders may confound the MSLT," the authors write."The MSLT remains the test of choice in patients without cataplexy since very few subjects in this category had low CSF hypocretin-1 levels."

因为hypocretin-1浓度不会明显地受到精神药物或其它睡眠障碍的影响，因此这项检查「可能对那些已经开始治疗的猝倒症患者，或当其它睡眠障碍混淆了多重入睡时间检查的测量时非常有用」，「多重入睡时间检查目前仍然是无猝倒症的最佳检查方式，因为这类患者的脑脊液中，hypocretin-1极少会有低浓度的现象」。

The reason i didn't realised there's chinese translation 'cause i usually burn a copy of all my wakin's cds as i have my discman and wakin's cds in my backpack and listen to them everyday, i don't want to spoilt the original one...so i seldom bring out the original cds..there are my collection. as for the burn cds...of course, those are for my personal usage.

我之所以没有发觉到CD里有中文翻译是因为我每一次买华健的CD，我都会自己烧一张拷贝，因为我包包永远放这我的随身听和华健的CD，每天都听，不想把买来的CD弄坏，所以极少那出来，它们都是我的珍藏，当然，那些拷贝的CD只共个人使用，决无它意。

There are many reports about analysis of isozymes between male sterile lines and their maintainers, but different crops or varieties in same crop expressed dissimilarly. There were few reports about comparison study of isozymes between male sterile line in cabbage and its maintainer at present. Most reports about analysis of isozymes between male sterile lines and their mainainter were limited 1-2 isozymes.

有关细胞质雄性不育系及其保持系花药同工酶分析的报道已有相当多，但不同作物表现不一样，同一作物不同品种表现也有差异，而且目前有关甘蓝雄性不育系和保持系同工酶比较研究的报道极少，有关细胞质雄性不育系与保持系的同工酶分析的报道多限于1—2种酶。

Sincerity is an openness of heart;we find it very few people;what we usually see is only an artful dissimulation to win the confidence of other.

真诚是一种心灵的开放，这种真诚只能在极少人身上找到。而我们通常所看到的真诚，不过是为了赢取他人的信任的巧妙掩饰罢了。

Time series prediction is a very important problem in many applications and the current prediction techniques are nearly all based on the Takens' embedding theorem. Many realistic systems are parameter-varying systems, and the embedding theorems are invalid, predicting the behavior of parameter-varying systems is more difficult.

时间序列预测是一类非常重要的问题，但基本上局限于参数不可变问题的研究，而对实际问题中经常出现的更重要的参数可变系统的预测，由于构成几乎所有已有预测技术基础的Taken嵌入定理不再成立，所以这方面的研究成果极少。

This rarely happens, but there are other more practical limits to endurance, including the need to reset instruments and to remove the inevitable weed, barnacles and other marine life that would encrust a glider during very long voyages.

这极少发生，但是仍有更多其他的现实因素限制它的持久力，包括重新安排设备以及铲除不可避免的海草，在长期的航行中，藤壶和其他海洋生物可能依附其上，给它包上一层硬壳。

First-generation search engine (1994 ~ 1995) in the amount of indexed pages are generally several orders of magnitude of about one million, using full-text search technology, and distributed parallel computing technology, but little re-collection of the page and go to refresh the index, the index is generally less at 1,000,000 pages, and its retrieval slower and generally have to wait for 10 seconds or longer, while absorbing the search request has also been very limited business model at the exploratory phase and not yet been born.

第一代搜索引擎(1994年～1995年)的索引网页量一般都在数百万量级左右，采用全文检索技术和分布式并行运算技术，但极少重新搜集网页并去刷新索引，一般都索引少于1，000，000个网页，而且其检索速度较慢，一般都要等待10秒甚至更长的时间，同时承受的检索请求也受到很大限制，商业模式处于探索期并且尚未成型。

The orbits of her mind rarely touched present interrogators for more than a moment.

她的思维轨迹很少触及到眼前的问话人，即使触及，也是极短暂的一瞬。

Rocks from the Earth"s mantle seldom see the sunlight. It"s only in places where tectonic plates have collided, like California, that mantle rock―loaded with magnesium, iron, nickel, chromium, cobalt, but low in calcium―has been squeezed to the surface.

来自地幔的岩石难见天日，只有在那些构造板块相互冲撞挤压的地方，就如加利福尼亚，地幔的岩石――富含镁、铁、镍、铬、钴，却含钙极少――被挤压到地面上来。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
