This eliminates the problem of S/N ratio degrading as the modulating frequency rises, but now results in a rolling off of the audio response if a "flat" FM signal is received.

这消除了随解制频率增大而下降的S/N比，但是造成音频频率响应的下降，当收到一个"平"的FM信号时。

The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

在一些自杀未遂立即急剧下降，也许这将更加有下降的桥梁，如果做了粉红或粉蓝。

Today, van den Bergh, the shares of the three quarterly disclosure revealed that the company achieve the July-September attributable to shareholders of listed companies net profit of 13.57 million yuan, representing a 96.1 percent decline in the same period last year, in addition to the impact caused by the earthquake in the asset retirement net profit, the company main products zinc ingots, as well as selling prices caused by a drop in gross profit margins in the third quarter decrease was mainly due to performance.

今天，布宏达，三季度披露的股份显示，该公司实现7-9月归属于上市公司股东的1357.00万元净利润，较同期下降百分之96.1去年，除了在资产报废净利润地震造成的影响，公司主要产品锌锭，以及出售了的毛利润率在第三季度下降造成价格下跌，主要是由于性能。

Analysis of the morphological feature, diversity and abundance of graptolite, brachiopod and radiolariaindicated that the sea-level in the Yangtze basin underwent the change from rising to falling, then to risingagain during the latest Ordovician to the earliest Silurian interval, and the maxium rising episode appeared inthe lower Tangyagraptus typicus Subzone and the maxium falling at the top of the Guanyinqiao bed.

笔石、腕足类、放射虫的形态、分异度和丰度的研究表明：扬子海盆晚奥陶世晚期至志留纪初期，总体上，海平面经历了上升→下降→上升的变化，海平面上升的最大阶段发生在Tangyagraptus typicus亚带下部，到观音桥层顶部，海平面下降到最低点。

However, says Mr Copland, the combined effect of the recession lowering GDP and the rash of new lawsuits, ranging from those against investment banks involved in the financial meltdown to the oil-spill cases, means that when the data are collated for this year and 2009 "the downward trend will almost certainly have been reversed."

然而，科普兰说，经济萧条，GDP下降，从金融危机中对投资银行的起诉到漏油案件的发生，新的集体诉讼案件不断涌现，各种因素互相影响，只要我们整理对照今年和2009年的数据就会发现"这种下降的趋势，几乎可以肯定地说，已经被逆转了。"

The results indicate that these two cysteine residues are directly responsible for DNA binding capacity.

在这次研究中，我们发现突变后的蛋白除了C43S外，其余的DNA结合利皆下降，尤其以C46S以及C64S下降最多，证实了这两个位置的胱氨酸与DNA结合有关。

Three preliminary conclusions could be approached as follows:(1) SST changes were distinctively characteristic of stepwise fluctuations. A warming trend during the last deglaciation was punctuated by a slightly cooling event which corresponded to the Younger Dryas. The Holocene episode could be divided into three phases of warming, continuously high temperature and cooling.(2) Two remarkable cooling records were documented around 4 kaBP and 1.5 kaBP after the megathermal of the Holocene.(3) Comparison between time series of MD05-2904 diatom R SST index and stalagmite δ^18O results from Dongge Cave, Guizhou Province suggested that changes in the East Asian Monsoon climate is synchronous with variations in the SST in the northern SCS since the last deglaciation and they might have a close correlation with each other

结果表明：(1)南海北部15 kaBP以来表层海水温度呈现明显的阶段性波动特点，即末次冰消期气候转暖过程中，12.9~11.5 kaBP前后温度略有下降，与新仙女木事件对应，全新世南海北部气候依次经历了升温期、高温期和降温期3个变化阶段；(2)全新世大暖期鼎盛期结束后，南海北部海水温度阶段下降，两次明显降温分别发生于4 kaBP前后和1.5 kaBP前后；(3) MD05-2904孔硅藻R值时间序列曲线与董哥洞D4石笋δ^18O曲线对比表明，南海北部表层海水温度变化与末次冰消期以来东亚季风强度变化关系较为密切。

The introduction of line searches requires the solution of sub-problems must be a dropped direction, that is g T k δ k 0, In this paper, we study the existed methods of solving sub-problems, prove Zhang and Xun 1999's dogleg method and Steihaug 1983's conjugate gradient method to meet the condition of adequate decrease, then the solution can be used in line search.

引入线搜索要求子问题的解必须是下降方向，即g T k δ k 0，本文研究了现存的子问题的求解方法，证明了Zhang和Xun1999折线法、Steihaug1983共轭梯度法满足"充分下降条件"，得到的解可以安全实施线搜索。

Based on the analysis of the fluid flow in the downcomer of an airlift internal loop bioreactor , a turbulent two-fluid model for airlift internal loop was proposed.

在对气升式内环流生物反应器内部流动分析基础上，全面考虑反应器下降管中气泡的并聚破碎、气液两相间相互作用和滑移等，建立了能描述反应器下降管中复杂流动的CFD数学模型。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
