This problem arises from the decline in bond prices and the insurance accounting convention that allows companies to carry bonds at amortized cost, regardless of market value.

事情的起因在于债券价格下跌，而会计原则又允许保险业以摊销成本而非市价列示其帐面价值，结果导致许多业者以摊销成本记录的长期债券投资金额达到其净值的二、三倍之多，换言之，只要债券价格下跌超过三分之一，便很有可能把公司的净值全部吃光，这其中甚至包括好几家知名的大公司在内，当然债券价格也有可能会回升，使得其部份，甚至全部的净值得以回复，但也没有人敢保证债券价

Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

According to people who had moustaches, inhaling the air component quantitative analysis and found that the air sucked into the presence of dozens of hazardous substances, including phenol, toluene, acetone, isoamyl asked diene, and other carcinogens,, Who had moustaches, who inhaled the air pollution index, is 4.2 times that of ordinary air.

The results showed that 1 transport of Gly-Pro was slightly quicker when Na+ replaced by K+ during the first period of 20 min;2 Na+ concentration gradient stimulated 4.6-fold of L-alanine transport, but had no effect on transport of Gly-Pro. Harmaline reduced transoport of L-alanine significantly but had no effect on Gly-Pro transport.

结果表明：(1)用K+替代Na+，并没有降低Gly-Pro在BBMV中的转运量，在孵育前20 min时间内，Gly-Pro的转运量稍稍提高；(2)Na+可使BBMV对L-丙氨酸的转运量提高到4.6倍，但不影响Gly-Pro的转运；二氢骆驼蓬碱显著地降低L-丙氨酸的转运，但对Gly-Pro的转运无影响。

交替运用计算几何中的最远点Voronoi图的性质和统计分析方法中的最小二乘法原理，可使最后参与求解最小外接圆的样本点数减至少量几个，相应算法的运算时间比以往的最优化算法快10倍以上。

Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

A group of scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, studied insects like water striders and then built a small robot using ultra-lightweight carbon fiber that is also able to walk on water. But they still have some improvements to make — they said the water strider is able to move about 20 times as fast.

宾州匹兹堡的卡内基美隆大学有一群科学家在研究水黾等昆虫的构造后，利用超轻的碳纤维制作了一个也能在水上行走的小型机器人，但他们仍有一些尚待改进的部分──他们表示，水黾在水面上移动的速度比这机器人快上约二十倍。
