1·The impact of raindrops on the loose soil tends to transfer fine clay particles into the tiniest soil spaces, sealing them and producing a surface that allows very little water penetration.
降水往往会把细小的粘土颗粒转移到土壤的最微小的空隙中,使这些空隙变得封闭,从而形成了一种几乎不允许任何水分渗透下来的表层土壤。
2·Some security crackers end up using their powers for good, providing penetration testing services or otherwise making efforts on the side of the angels.
一些安全破解者最终会将其能力用到好的方面,比如提供渗透测试服务,或者是其他一些站在天使这边的所为。
3·One of the best security tests to perform before an SOA is moved to production is a penetration test.
要在将SOA转移到生产环境之前执行的最合适安全测试之一是渗透测试。
4·Now, the penetration and impact of social media is such that failing to understand what consumers are saying about a company online has become a business risk.
由于社交媒体拥有庞大影响力和渗透作用,如果不能了解消费者对公司的线上评论,将成为一种商业风险。
5·Password cracking is a term used to describe the penetration of a network, system, or resource with or without the use of tools to unlock a resource that has been secured with a password.
密码破解是用以描述在使用或不使用工具的情况下渗透网络、系统或资源以解锁用密码保护的资源的一个术语。
1·The differences in the penetration mechanism between cuspidal and blunt projectiles are studied.
研究了尖头、钝头弹在侵彻机理上的差异。
2·The model is implemented through a user defined material model in LS-DYNA. The model parameters are calibrated and validated by the data from related concrete penetration tests.
利用LS - DYNA程序的用户自定义材料模型开发并实现了模型算法,并用有关混凝土侵彻试验结果对模型参数进行了标定。
3·To enhance the damage capability of the concrete-piercing shell, the penetration depth must be raised.
为了提高混凝土破障弹的威力,必须提高其侵彻深度。
4·With hemispherical EFP simulation model, the penetration process of EFP that satisfies the simulation ratio are calculated using explicit finite element program LS-DYNA in this paper.
在此基础上以球缺型爆炸成型弹丸为计算模型,应用显式有限元程序LS-DYNA对满足模拟比的爆炸成型弹丸侵彻钢靶的过程进行了数值模拟。
5·The numerical results indicate that, the shaping of the prototype and the simulation EFP accord with the analogue rule, and the depth of penetration on steel target also satisfy simulation ratio.
数值模拟结果表明,模拟弹与原型弹的成型符合相似律,其对钢靶的侵彻深度也满足模拟比。
