The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

Using the primers from SRY gene-HMG Box for PCR amplification in genomic DNA of Muntiacus reevesi cell strains, a 220bp fragment was obtained in the male but not in the female.

应用人的性别决定基因SRY (Sex-determining Region Y gene， SPY)中HMG框内的一对引物，对小麂细胞株的基因组DNA进行PCR扩增，得到雄性小麂细胞的220bp扩增产物，而在雌性小麂细胞中未发现扩增产物。

When the dominant feature of cyber-based transaction is "namelessness", it cant be accomplished without the participation of a third party who is recognized by the contracting parties.

另外，数据电文能否作为证据在诉讼法中予以主张，我国的《民事诉讼法》也未作规定，由于网络交易的最大特点是&匿名性&，这一特征决定了交易的达成必须要有双方共同承认的第三方参与才能完成。

If the Merchant fails to take delivery of the Goods during a reasonable time or whenever in the opinion of the Carrier the Goods are likely to deteriorate, decay, become worthless or incur charges whether for storage or otherwise in excess of their value, the Carrier may, at its discretion, without prejudice to any rights which he may have against the Merchant, without notice and without any responsibility whatsoever attaching to him, unstuff, sell, destroy or dispose of the Goods at the sole risk and expense of the Merchant, and apply any proceeds of sale in reduction of the sums due to the Carrier from the Merchant.

如果货方未在合理的时间内提取货物，或者只要承运人认为该货可能腐坏、变质、无价值可言，或在将其存储或做其他处置时其所需费用将超出该货价值，承运人便可自行决定，在不影响承运人对货方的权利，不予通知而且在不对承运人加诸任何责任的情况下，将箱中货物取出、出售、销毁或加以处置，而由货方承担全部风险及费用，并将货物价款用于扣减货方结欠承运人的款项。

The mechanical properties and the electrical properties of the cantilever, such as spring constant, resonant frequency, mechanical quality factor, piezoelectric output and the noise level, determine the resolution of a AFM when piezoelectric cantilever is used as the force sensor.

在作为原子力显微镜的力传感器使用时，压电探针的机械特性，如弹性常数、谐振频率、谐振质量因子，以及电子特性如压电输出、噪声水平等决定了原子力显微镜的分辨率，而对于带有针尖和三角形前端的PZT压电探针，这些特性迄今未得到系统研究。

In 1769 he published An Essay towards a History of Comets. Amidst his various professional avocations, Burney never lost sight of his main project—his History of Music—and decided to travel abroad and collect materials that could not be found in Britain.
