时样

So, we discuss the asymptotically best linear unbiased estimator for the logistic population based on the selected order statistics, give the pr.

为缓解这一困难，本文讨论利用样本分位数的Logistic总体的近似最佳线性无偏估计，给出估计量的大样本性质，以及样本分位数不超过10情形下，估计量有渐近最大相对估计效率时样本分位数的选取方案等。

The composition and development of plant community in the process of natural vegetation restoration on the rehabilitated land in early years were studied by means of fixed and temporary sample plots in Yanlan experimental area.

：用固定标准地结合临时样地的方法对延安研究区退耕初期不同退耕年份植被恢复过程中群落形成、组成及其变化进行了研究。

So,whether or not adopt this method inpractical production should be determined according the area of compartment or sub-compartment,meanwhile thinking of whether the amount of work increased from addingtemporary sample plots is larger than the work load of traditional inventory.

因此，在实际生产中是否采用该方法，应根据林班或小班面积大小，考虑增设临时样地所带来的地面调查工作量与传统调查相比是否占优势来确定。

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％。
