夏季

But there is also happiness on Memorial Day, because it is considered the beginning of summer.

但在这个纪念日也有欢乐，因为那天被看成是夏季的开始。

By means of high resolution field emission scanning electron microcopy and image analysis technology,the individual particle morphology and their size distribution of particle number and volume of Summer PM10 in Zhengzhou were investigated.

分析了2005年郑州市大气可吸入颗粒物(PM10)的污染特征，应用高分辨率场发射扫描电镜和图像分析技术，研究了郑州市2005年夏季大气单颗粒物的形貌特征以及PM10的数量-粒度和体积-粒度分布。

The atmospheric transmittance database for l064nm laser is created basing on the FASCODE. The model atmosphere is midlatitude summer. The slant path length covers (0~10) km with the alternation of 0.1km. The elevation covers 0°~91° with the alternation of 5° The surface range covers (5~20) km with the alternation of 1km.

利用FASCODE计算出1064nm激光的大气透过率，建成透过率数据库，该数据库对应的大气模型为中纬度夏季，斜程范围为(0~10)km（间隔0.1km），仰角范围为0°~90°（间隔5°），地面能见度范围为(5~20)km（间隔1km），数据库可以根据需要进行扩展。

By adopting atmospheric condition of the midlatitude summer model in the daytime, no clouds urban aerosols, spring-summer aerosol profiles and background stratospheric profiles extinct model, the typical spectrum characters of target background radiance, contrast and transmittance are computed by the radiative transfer computation software MODTRAN, and then the spectrum characters in the wavelength bands are analyzed.

选择中纬度夏季白天、无云城市气溶胶模式、春夏季气溶胶廓线以及背景平流层廓线和消光的大气条件，利用辐射传输计算软件MODTRAN计算了目标背景亮度、对比度以及透过率的典型光谱特征，并进行光谱特征分析，然后在其他大气模式下对所选波段进行了验证，从而选择出目标探测的最优波段。

The Mavericks have nothing to show for their active summer and blockbuster midseason trade.

小牛队夏季的活跃和赛季中旬的重磅交易没有任何效果。

Conveniently, the miniature golf course was very close to the beach.

饭后，我们去打小型高尔夫球——这是她最喜欢的夏季运动。

Today the summer has come at my window with its sighs and murmurs;and the bees are plying their minstrelsy at the court of theflowering grove.

今天，夏季轻嘘微语着来我窗前；群蜂在花树的庭院中尽情吟唱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
