查询词典 present simple

In this article,students actually present at exams are regarded as simple random sampling of all the students,and the sampling and assessing ways are applied.

将实考考生看作为考生总体的一个简单随机样本，应用抽样估值的方法，在若干合适的概率分布模型下，收集和推演了考生总体合格率的一些估计公式，以估计有考生缺考时，考生总体的合格率。

The permanent magnets are now mouthed at the exterior of the high-pressure vessel and are no longer in contact with the fluid sample. So this construction of equipment decreases the contamination of each other. Concerning the temperature-control system, the present instrument employs one non-vibrating new technology. In the high pressure systems, a simple and fast high-pressure pump was used to generate hydraulic pressure. This equipment is more easy to control than the literature\'s methods. A digital lock-in amplifier has been used as sinusoidal current function generator and the induced signal detector.

本文对振动丝粘度密度仪在设计方案上进行了大量改进，把磁体从高压容器的内部移植到容器的外部，提高了容器的化学适应性，采用了无振动的恒温新技术，利用了方便快捷的加压方式，极大的方便了实验的进行，减少了实验的工作量，用数字Lock-in锁相放大器作为驱动信号发生器和诱导信号检测器，设备既简单又极大地提高了信号的检测灵敏度。

Leaves simple, alternate, opposite, or whorled, petiolate or sessile, papery or leathery, with pinnate veins, margin entire, leaves rarely reduced and scalelike; stipules absent, sometimes spiniform or scalelike appendages present.

单叶，互生，对生，或轮生，具叶柄的或无梗，纸质或革质，托叶无，有时有刺状或者鳞片状附属物。

The general timing counter applied in computer includes configuration register TCCFG control word register TCCON, state register TCSTA, initial value register TCPAL and internal counter TCCOUNTER. Both the said internal counter TCCOUNTER and the internal bus are in 32 bit width and the 32 bit read-out bus and 32 bit write-in bus are connected directly to the 32 bit internal bus. Therefore, the present invention has the advantages of long counting time, high precision and simple chip design and programming.

本发明公开了一种应用于计算机领域中的通用计时计数器，包括配置寄存器TCCFG、控制字寄存器TCCON、状态寄存器TCSTA、初值寄存器TCPVAL和内部计数器TCCOUNTER；所述的内部计数器TCCOUNTER和内部总线都是32位宽度，其32位的写入总线和读出总线都直接连到32位的内部总线上；从而克服了现有技术中计数时间短、编程和芯片设计复杂、计数精度低的缺点，使得计数时间长、精度高、芯片设计和编程简单。
