查询词典 insufficient

With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples. The direct determination of extremely low concentration of trace element with modern atomic spectroscopic method, such as atomic absorption spectrometry is so difficult. On one hand, the limitations are associated not only with the insufficient sensitivity of these techniques but also with matrix interference.

随着科学技术技术的发展，在进行地质、环境、生物等样品中痕量金属元素的测定时，常常要求达到ppb级的水平，虽然火焰原子吸收分光光度法具有很高的灵敏度，但是要直接测定这些样品中的痕量组分却很难，这是因为，一方面，样品本身的物理化学状态有的不适合直接测定，或组分的含量低于分析方法的灵敏度；另一方面是存在基体干扰。

However, has these is only insufficient to go attractively.

然而，单有这些是不足以诱人前往的。

On the mobile communication systems,a forward error correction or automatic repeat request scheme may be insufficient to achieve the desired performance due to the time-varying nature of the channel.

由于移动信道的时变和多径传输特性，常导致系统有较高的误码率，而单纯的FEC或ARQ机制往往无法提供所希望的系统性能。

Of course, the second autopsy has insufficient.

当然，第二次尸检也有不足。

This is because we have insufficient data to tell the average before that time.

这是因为在此时间之前的数据不够计算出平均值。

Because we have insufficient data to tell the average before that time.

However, with the memory of suppression under previous regimes fading--Mr Museveni has ruled for 23 years--and with the allocation of senior government positions (at some stage the prime minister, vice-president and finance minister have all been Baganda) insufficient to appease hard-line Buganda nationalists pressing for more autonomy, a showdown is looming.

但是，由于随着新政权统治时间的增长，（到现在穆塞韦尼总统已经统治了23年）在前政权下曾经遭受统治者镇压的历史渐渐被淡忘，（有些时期，总理副总统以及财政部长全都是巴干达人）已经不足以满足他们，这些有着强硬态度的布干达国家主义者一直迫切要求得到更多的自治权，摊牌的时刻迫在眉睫。
