稀少

Odonates include insects we commonly called dragonflies and damselflies. Species from a scarce odonate group, known as "diverse damselfly", are considered living fossils.

蜻蛉」二字所指的就是我们所称的蜻蜓、豆娘，此外尚包含一类种类数稀少的蟌蜓，是一群具有相当古老历史的昆虫

In fact, in reallife, the prey species will be usually a?ected by the patchy environment, oncethe food in their patch is exhausted or there are abundant natural enemies intheir patch, they will leave in search for new habitats or refuges, at the sametime, the predator species also will be confined in a isolated patch, when thereis little food to feed on or the last prey is eaten the predators will depart andbecome predator dispersers.

事实上，在现实环境中食饵种群通常会受到斑块环境的影响，一旦在一个斑块上的食物吃完了或者存在太多天敌，它们会离开这个斑块寻找新的栖息地或避难所，同时捕食者种群同样会受到隔离斑块的影响，当在某个斑块上食饵种群稀少或吃完了最后一个猎物，捕食者种群将会离开变成迁徙者到其他栖息斑块上寻找猎物。

The results achieved by the unsteady simulation on the basis of Reynolds averaged Navier-Stokes are fitted to the experiential wind profile well. The results indicate that the numerical simulation based on CFD provides a new solution to study the downburst wind characteristics under the current conditions without detailed full scale data.

数值结果表明，基于雷诺平均的Navier-Stokes方程进行的非定常数值模拟结果同根据实测数据提出的三种经验风剖面吻合良好，在目前实测资料稀少的情况下，有助于更好地研究下击暴流风的基本特征。

But it's a little-acknowledged fact of life in suburbs, exurbs and cities with scant public transportation: A great many drivers on the road have had at least a drink or two, or three, or more.

不过在公共交通稀少的市区、远郊区和城市，有一个很少有人承认的事实：很多开车的司机都至少喝了一两杯，甚至更多。

The sparsely settled, far-northern state of Alaska is the largest of America's 50 states (in many countries they would be called provinces).

人口稀少的阿拉斯加州位于美国的最北部，在全国50个州中，它的面积最，比中国四川省的两倍半还。

All weekend at the impressive Hermann Tilke-penned circuit, observers have marvelled at the scarcity of spectators, as did the Australian driver as he and his fellow drivers waved at near-empty grandstands while on the back of a slowly circulating flat-bed truck prior to Sunday's race.

整个周末都在令人印象深刻的赫尔曼蒂尔克写电路，观察员惊奇稀少的观众一样，澳大利亚的司机，他和他的同伴挥手时，司机几乎空看台，而在后一个缓慢循环平板卡车之前，周日的比赛。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
