S And if we go ahead and superimpose the3 s on top of the3 p, you can see that the3 s actually has some bit of probability density that gets even closer to the nucleus than the3 p did. 如果我们继续将,重叠到3p上面,你们会看到3s事实上,有一点概率密度,距离原子核更近,比3p轨道。
Such as easy cutting paste, a bit not careful density board they smoke. 譬如容易切割糊,稍不留神密度板就冒烟了。
With the development of the electron industry, the area of single recorded bit becomes smaller and smaller, and the areal recording density in magnetic recording is required to become higher and higher. 随着电子产业的不断发展,单个记录位的面积越来越小,对磁记录材料面密度的要求也越来越高,所以提高磁记录材料的记录性能已经成为研究焦点之一。
For IR-UWB system with BPSK modulation, the bit error rate is calculated for UWB receiver at different directions under situations of fixed signal-to-noise ratio or fixed noise power spectrum density in the channel. 对于采用BPSK调制的IR-UWB通信系统,文中计算了在固定信噪比和固定噪声功率谱的两种不同情况下,接收机与发射机间具有不同相对位置情况下的误码率。
Bit Density Dependence of Thermal Relaxation of Recorded Signal on Hard Disk 磁盘记录信号的热磁衰减现象的记录密度依赖性
According to the theories of breaking rock and wearing of the PDC drilling bit, it researches the arranging of cutting gear and arranging density which influence to the drilling bit property. 根据PDC钻头的破岩原理和磨损机理,研究了切削齿的布置方式和布齿密度对钻头性能的影响;
Bit allocation algorithm for OFDM-UWB with constraints of uniform power spectrum density 均匀功率谱密度约束下的OFDM-UWB比特分配算法
Compared with magnetic bubble storage memory, the bit density of BLM increases drastically. 与磁泡存储器相比,BLM的存储密度大大提高。
Secondly, different hardness of bit base, diamond particle size and density are chosen for different strata or rocks; 二是根据不同地层及岩性选用不同胎体硬度金刚石钻头、不同的金刚石粒度与浓度;
The results show that the effectiveness of removing impurity under continuous process is a bit lower than that under motionlessness, and the density difference has a little influence on the effectiveness of removing. 结果表明,熔体连续处理条件下的夹杂物去除效率比熔体静止时的略低,而夹杂物与熔体之间的密度差对电磁分离时的去除效率影响不大。
The result of analysis indicated that match between formation and bit is the key fac-tor affected PDC bit's drilling and drilling fluid density is the key measures for the drilling result of PDC bit, which is just on contrary with roller bit. 分析表明:影响PDC钻头钻进过程的关键因素是钻头与地层的匹配,钻井液密度已成为影响PDC钻头钻进效果的关键措施,这一点与牙轮钻头相反。
Also, for the hole collapse and drill bit accident, The reason why is mostly because the soil is not compact, not of high density and low anti-interference capability. 同时,对于工程中的塌孔埋钻事故,其原因大多是因为孔壁土壤不够紧凑,密实度不高,抗干扰能力差。
They need to not only keep the inherent advantages of high bit density and low power consumption, but also compare favourably with SRAM in terms of speed and logic process com-patibility. 不仅需要其仍然保留在记忆密度和电路功耗上的固有优势,又希望在速度和逻辑工艺兼容性上可以媲美SRAM。
