1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.

1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

In this thesis, the performances of liquid crystal display with different backlight light sources were analyzed by the optical spectrometer. The backlight sources included three different kinds of white light-emitting diodes and a traditional cold cathode fluorescent lamp.

The results of three cladistic methods showed: the consanguinities of different genera in a same tribe were closer, such as Chalcis and Conura, Trigonurella, Megalocolus and Trigonura; the consanguinities of genera between different tribes were farther, such as Chalcis and Brachymeria, Dirhinus and Hallichella; Chalcis, Conura, Brachymeria and Epitranus were the most primitive relatively, Tainaniella and Oxycoryphe were the most evolutional, the consanguinities were the farthest between the former and the latter; the genera with the closest consanguinities were: Tainaniella and Oxycoryphe, Proconura and Nipponochalcidia, Chalcis and Conura, Megalocolus and Trigonura, they were regarded as 4 pairs of sister groups.

三种支序分析方法一致支持的结果为：同一族内成员之间亲缘关系较近，如小蜂属和卡诺小蜂属，微三角小蜂属、细尾小蜂属和三角小蜂属之间；不同族内成员相互之间的亲缘关系则较远，如小蜂属和大腿小蜂属之间，角头小蜂属和截胫小蜂属之间；小蜂属、卡诺小蜂属、大腿小蜂属和脊柄小蜂属相对最为原始，而泰内小蜂属和背突小蜂属最为进化，前者和后者之间的亲缘关系最远；亲缘关系最近的有：泰内小蜂属和背突小蜂属，泊卡小蜂属和日本小蜂属，小蜂属和卡诺小蜂属以及细尾小蜂属和三角小蜂属，它们各自之间都构成姊妹群关系。

Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

If the above-mentioned display numeric correctly, that is, there is a problem in this area of the motor to the power of checking supplied motor insurance for damage, in General, or this insurance go bad, or connect the line break, the motor go through, this problem can be solved.

如果上背提到的表现数值变态，那么不离是电机这方背有题目了，可以查抄供答电机电源的保障是否败坏，凡是环境下，给么是此保障坏失，给么是不断递电机的线折断，澈底查抄后，此题目可以处置。

It is shown in an external quantum efficiency diagram that the planar back surface has the best response to a wavelength between 440 and 1000 nm and the sawed-off back surface has a better long wavelength response.

外量子效率的测量显示，平背表面对440~1000nm的光响应都是最优，截断金字塔背表面有较好的长波响应。

In a study of New Zealand's "living dinosaur" the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000 years old.

在研究新西兰"活恐龙"刺背鳄蜥的过程中，同为进化生物学家和古遗传专家的大卫·兰伯特教授以及他来自艾伦·威尔逊分子生态与进化中心的团队鉴定出，从古代刺背鳄蜥骨骼中提取分析所得的DNA序列竟有8000年之久。

The TCM symptoms of hypokinesia, muscle rigidity, bradykinesia, nape rigor, diziness, insomnia and dreamful sleep, sore waist, skelalgia and constipation in treating group has improved than that in controlled group. Compared with placebo group, the"off"time of patients in NKN group reduced 27% averagely; the"on" time prolonged 19% averagely.

脑康宁组证候总有效率76.67％，对照组为50.0％，两组比较有显著差异（P＜0.05）；脑康宁组肢体拘挛、运动迟缓、颈背僵直、头晕、失眠多梦、盗汗、腰酸腿痛、便秘等症状均有明显改善（P＜0.05）；脑康宁组用药后&关期&平均减少27％，&开期&平均延长19％；用药后生活质量评分的各方面均有明显改善，且与对照组比较有明显差异。

By 2012, say analysts in Shanghai, as much as $2 trillion (￡1.69 trillion) worth of trade flows may be settled using the "redback" as China stretches its commercial tentacles throughout the commodity-producing world and the emerging economies of Asia, Latin America and the Middle East.

上海的一些分析家认为，到2012年，随着中国的商业触角延伸到全部的日用产品世界和亚洲，拉美及中东的新兴经济体，差不多有2万亿美元（1.69万亿英镑）的贸易流动额将使用&红背&结算（注：人民币，美元GREENBACK，绿背
