The perpendicular line from neurocanal most lateral to the sa line and sb line were defined as h1 and h2 respectively,the length of Ph1 and Ph2 were measured,the diameter of screw smaller than 2 times of Ph2 lengths was regarded as safe.The line from the first posterior foramen lower end to the second posterior foramen upper end was obtained.

第一骶后孔下缘最低点与第二骶后孔上缘最高点连线为WY，平分椎弓根的平面与WY线的交点为O，测量WO的距离，O点在W的下方时为正值，O点在W的上方时为负值。

On the contrary, at the moment γ changes suddenly the pulselike SP change ΔV will always arise no matter the increment Δγ is positive or negative. The positive or negative sign of Δγ gives opposite effect on ΔV.

反之，无论γ的增量Δγ为正值或负值，当γ突变，即对样品进行突然加卸载的时刻则出现了脉冲状自电位信号ΔV，Δγ的正或负对ΔV的影响是相反的。

The metal elements of the volcanic-hosted massive sulfide deposit have two sources, the copper and zinc are derived from rhyolitic magmas whereas the lead are probably related to old sediments overlying the rhyolites.(4) It is suggested here that the volcanic rocks hosting massive sulfide deposit in the north Qilian orogen, which are previously considered as a bimodal suite of Neo-proterozoic to middle Cambrian age in a continental rift, are virtually related to subduction magmatism in Ordovician age, and there might have no continental rift magmatism of Neo-proterozoic to middle Cambrian in the north Qilian.

Th/Ta比高(5.0～11.7)，εNd为较大的负值(-2.6～-8.4)，流纹岩的形成可能是两个端元组分混合的过程、或是上地壳混染的结果，形成在活动陆缘环境；(3)北祁连块状硫化物矿床成矿金属物质具有两种来源，Cu、Zn等来源于流纹岩，而Pb的来源可能与古老沉积物有关；(4)本文认为，前人厘定的北祁连新元古代-中寒武纪赋存块状硫化物矿床的大陆裂谷双峰式火山岩应是与俯冲作用有关的奥陶纪火山岩，说明北祁连可能不存在新元古代-中寒武纪的大陆裂谷活动。

It has been pointed out that a regative error or even an apparent negative roading of tgδ may result if there is a T-network of disturbance present in the measuling circuit or within the test sample itself, but these phenomena have not yet been fully investigated.

如果在测试电路或试样本身内存在T形干扰网络，则tgδ测量值就可能出现负误差或甚至出现负值。

According to Di Rucker result that equation provide, except that energy fetches the state that is on the occasion of electron, energy state of can fetch negative state, alling and shoulder can distribution of state zero point totally symmetrical to energy.

按照狄拉克方程给出的结果，电子除了有能量取正值的状态外，还有能量取负值的状态，并且所有正能状态和负能状态的分布对能量为零的点是完全对称的。

Most conventional methods for the extraction of substrate network were based on the use of frequency behavior of Y22 + Y21. However, we found that the feedback signal through the internal circuit elements makes the conductance of the substrate network underestimated while makes the susceptance of the substrate network overestimated. If conventional methods are directly performed on large area SiGe HBTs, a negative effective substrate resistance will be extracted. In the first part of the thesis, a new extraction method for the substrate network parameters of SiGe HBTs is proposed. When extracting the substrate network parameters, the feedback signal through internal circuit elements is considered. All the circuit elements of substrate network are extracted from Ysub instead of Y22 + Y21. The extracted substrate network parameters show a different bias dependence as compared to the conventional methods. By using a simple n+-p junction, we successfully explained the extracted bias dependent substrate network parameters. We developed a series linear regression equation to extracted the intrinsic circuit elements from the ABCD parameters. Compared with the conventional methods which extracted the circuit elements from Y-parameters or Z-parameters, the proposed method is much simple and easy to implement in the computer programs.

传统方法在萃取基板网路参数时，常常由所量得的Y22 + Y21来著手，但我们的研究发现，利用Y22 + Y21的频率关系来萃取基板参数时，基板网路的电导会被低估而基板网路的电纳则会被高估，另外传统基板网路参数萃取方法在萃取大尺寸元件基板网路参数时会得到负值基板等效电阻，以上的非理想效应皆因忽略部份信号会经由本质参数对基板网路做回授的影响，因此本论文中提出一个新的基板网路参数萃取方法，在萃取基板网路参数时考虑了由本质参数所回授的信号，并且由Ysub而非Y22 + Y21萃取基板等效电阻、基板等效电容及基板与集极空乏电容，成功的解决上述的一些非理想效应，所得到的基板网路参数与集极偏压的关系与传统方法所得的趋势相异，经由一个简单的模型成功的解释了所萃取得到的基板网路参数与偏压的关系，在萃取本质参数时，我们舍弃传统萃取方法中常用的Y参数或Z参数萃取方程式，而改用ABCD参数，并提出一系列的线性回归方程式，萃取所有的本质参数，与传统方法比较起来，比较简单而且容易建立在使用者的参数萃取软体中。

Synthetic ettringite precipitated from solution shows a highly positive zeta potential, hence it adsorbs great amount of negatively charged superplasticizer. Monosulfate has only a slightly positive zeta potential and adsorbs smaller amounts of superplasticizer. For syngenite, portlandite and gypsum, the zeta potential is around zero or negative.

以溶液沉淀析出法人工合成的AF具有较高的正zeta电位，能吸附大量带负电荷的超塑化剂，AF仅带少量正电荷，其吸附超塑化剂相对较少，钾长石、氮氧钙石和石青的zeta电位几乎为零或负值，因而基本不吸附超塑化剂。

The results of DLVO theoretical calculations indicate that the total acting energy between the titanaugite and ilmenite particles at pH 5.9 is negative, showing as attraction, which causes the superfine titanaugite particles attach on the surface of ilmenite. At pH 8.5, because of large electrostatic repulsion energy, the total acting energy shows as strong repulsion, thus the superfine titanaugite particles can not attach on the surface of ilmenite.

DLVO理论计算结果表明：当pH=5.9时，两种矿物颗粒间的总相互作用能为负值，表现为相互吸引，微细粒级的钛辉石会在钛铁矿表面上粘附，使钛铁矿的回收率显著降低；当pH=8.5时，由于静电排斥能大，总相互作用能仍表现为较强的排斥力，微细粒钛辉石不能粘附在钛铁矿表面。
