NULL and Default Value Compression ( V8 GA): Compression for null, zero length data in variable length columns and system default value.

NULL值和默认值压缩（V8GA）：对可变长列中的零长度空数据和系统默认值进行压缩。

The roughness length of vegetation cover surface depends on the type, height, coverage of the vegetation, zero-plane displacement height, free velocity, friction velocity and the atmospheric stratification stability.

植被覆盖面空气动力学粗糙度长度取决于植被类型、植被高度、覆盖度、零平面位移高度、自由风速、摩擦速度以及大气层结稳定度。

The extrapolation length δ is greater than zero and is proportional to the correlation length. The value relates to the harmonic oscillator stiffness and independent of the temperature.

外推长度δ大于零、正比于膜中电偶极子间的关联长度η，δ/η与偶极子倔强系数的大小有关、与温度无关。

At the same time, same security level as RSA has can be achieved by ellipse curve-based zero knowledge proof with the key much shorter in length than that of RSA.

同时基于椭圆曲线上的零知识证明可以用比RSA短得多的密钥，达到与RSA同等级别的安全性。

The results for reconstruction of discrete finite length signal from FT spectral magnitude or phase are further extended for that of continuous signal, and both are expressed in a unified form by the zero set of the extended FT.

将幅谱、相谱重建离散有限长信号的结果推广于连续场合，并用延拓FT的零点集统一表述。

Enabling value compression allows for no disk storage to be consumed by NULL values, zero length data in variable length columns and system default values.

数值压缩不为空值、可变长度列中的零长度数据和系统默认值提供磁盘空间。

To determine whether any sockets are ready, the caller must test the length of all three lists; no socket is ready only if all three lists have zero length.

为了判断是否有可用的socket，调用者必须要对方法参数中的三个列表各自的长度进行测试；如果三个列表长度都是零，那么就是没有可用的socket。
