Particular landform of Tacheng Region allows water vapor from the west, so as to form many medium-and small-sized rivers. The seasonal snow covers the hills. During the snow-melting season in spring, the rivers have the character of spring flood, which makes uneven distribution of annual runoff and results in a disadvantaged allocation of water resources.

塔城地区独特的地形为西来水汽的输送提供了条件，从而形成了众多中小河流，而中低山带季节性积雪的消融又使河流呈现出春汛的特点，使得径流年内分配不均，对塔城地区水资源配置极为不利，开展径流量的预测研究，将为水资源的优化配置提供科学的理论基础。

When muddy water is still, sediment will easily be deposited on the sand column to be a new layer for infiltration which is disadvantage to sediment entrance.

静止浑水入渗时沉积比较快，沉积层覆盖在砂柱上方，成为新的入渗层，对分析入渗滞留的状况造成不利的条件。

The only detrimental factor in the well-being of the goji berry plant is wet and soggy soil conditions.

How to increase comfortable time of indoor environment and reduce the occurrence of bad environment based on the local climate is an important task in the architectural field. The paper firstly obtains neutral temperature of Zhejiang area based on a great deal of inquisitions.

基于建筑所在地区的气候环境，在不借助机械设备条件下通过采用建筑气候设计措施，延长建筑室内环境的舒适时间、减少不利环境的出现几率，是当前建筑研究领域中一个重要课题。

Since there are some disadvantages, such as magnitudes, reference systems and difficulties in observing an asteroid during its motion in its whole orbit, etc., when the asteroid is observed simply by means of the meridian or photograph methods, a new method for observing asteroids with a lower latitude meridian circle and a CCD measuring device is proposed according to the conditions of the geographic latitude of the Yunnan Observatory which can be used to observe the whole orbit of an asteroid.

考虑到单纯用子午方法或照相方法对小行星进行观测存在着因星等、定标星系统，以及难于在小行星运行全轨道上进行观测等方面的不利因素，在本文中，根据云南天文台能观测小行星全轨道的地理纬度条件，提出利用低纬子午环与CCD测量装置相配合，并利用低纬子午环直接提供的定标星，在一个统一的基本仪器系统中，通过对小行星在全轨道上均匀分布的观测，获得高精度的小行星观测资料，以便得到更准确的星表零点改正。
