Assume β=1, and confidence level is 0.95, the length of normal confidence interval is compared to the length of shortest confidence interval, the results show: both absolute difference d and relative difference e are decreased by the increasing sample number n, when n≤9, e≥10%.

在假设参数β=1，置信水平为0.95的条件下，比较了常用置信区间与最短置信区间的长度，结果表明：两者长度的绝对差d和相对差e均随样本容量n的增大而减小，当n≤9时，e≥10%。

And the development and formation of the sieve tube elements of the different cultivars were influenced by the different levels of B: the sieve tube elements of the two cultivars were not formed at the level of 0.001mg/L; At the level of 0.01mg/L, the sieve tube elements of the high efficiency (Qingyou 10) cultivar could be formed, but the structure of the sieve tube elements was not complete, and the abruption and differenciation of the sieve tube elements of the low efficiency cultivar were inhibited, they were not formed; At the level of 0.01mg/L, the sieve tube elements of the two cultivars were formed.

不同硼水平下，不同硼效率甘蓝型油菜品种根尖筛管分子的发育与形成受到影响：硼浓度为0.001mg／L时，两个油菜品种都不能形成筛管分子；硼浓度为0.01mg／L时，硼高效品种青油10号筛管分子可以形成，但结构受到破坏，而硼低效品种Bakow筛管分子的分裂与分化受阻，几乎不可能形成成熟的筛管分子；硼浓度为0.5 mg／L时，两个油菜品种都能正常生长发育。

To stop serious bleeding,first lay the affected person down,with the head sightly lower than the body.if possible,lift the wounded part above the level of the heart.

如严重出血，首先让伤者躺下，头部稍低於身躯。如果可能的话，把受伤的部位托高至高於心脏的水平。

By statistical significance test, the results of determination were compared with those of standard methods with no significant difference at 0.05 level.

通过对模型进行t-检验，在显著性水平大於0.05的条件下，其测定结果与标凖方法的测定结果对比，两者无显著性差异。

We also got STM images of denatured fibroin under stress or by methanolin molecular level. We found the conformation of silk fibroin is changed from α-helixand random coil structures to β-strand and loosed α-helix formation. We employed the STM to explore the structure and morphology of silk fibroinin the middle silk gland of mature silkworm.

我们在分子水平上对在冰冻和甲醇处理下的丝心蛋白的变性情况进行了STM研究，我们发现丝心蛋白的构象由α-螺旋结构和无规线团的结构向β-伸展链和松散折叠α-螺旋结构转变我们还用STM对熟蚕的中部丝腺体中的丝心蛋白的结构形态进行了研究。

Based on the similarity principle ,the mechanical characteristics of piles are obtained.
