问题描述

好的，所以基本上我在javascript中有这个代码它的数学但是我似乎无法在vb.net中获得相同的结果iv'e尝试了很多方法但是无法让它工作我希望得到一些帮助这里是代码：

Ok, so basically I have this code in javascript it's math but I can not seem to get the same result in vb.net iv'e tried lots of ways but can't get it to work I was hoping to get some help here's the code:

function doTheMaths() {
                var o = data[$("#origin").find(":selected").text()];
                var d = data[$("#destination").find(":selected").text()];
                var p = data[o.parent];
               
                // phase angle:
                var t_h = Math.PI * Math.sqrt(Math.pow(o.alt+d.alt, 3)/(8*p.mu));
                var phase = (180 - Math.sqrt(p.mu/d.alt) * (t_h/d.alt) * (180/Math.PI)) % 360;
                $("#phase").val("" + Math.round(phase*100)/100 + "°");
               
                // velocity:
                var exitAlt = o.alt + o.soi; // approximation for exiting on the "outside"
                var v2 = Math.sqrt(p.mu/exitAlt) * (Math.sqrt((2*d.alt)/(exitAlt+d.alt)) - 1);
                var r = o.radius + parseInt($("#orbit").val());
                var v = Math.sqrt( (r* (o.soi*v2*v2 - 2*o.mu) + 2*o.soi*o.mu) / (r*o.soi) );
                $("#velocity").val("" + Math.round(v*100000)/100 + " m/s");
				
				// delta-v:
				var v_o = Math.sqrt(o.mu/r);
				var delta_v = v - v_o;
				$("#deltav").val("" + Math.round(delta_v*100000)/100 + " m/s");
               
                // ejection angle:
                var eta = v*v/2 - o.mu/r;
                var h = r * v;
                var e = Math.sqrt(1+((2*eta*h*h)/(o.mu*o.mu)));
                var eject = (180 - (Math.acos(1/e) * (180/Math.PI))) % 360;
               
                if (e < 1) {
                        // maltesh's solution for elliptical transfers
                        var a = -o.mu/(2*eta);
                        var l = a*(1-e*e);
                        var nu = Math.acos((l-o.soi)/(e*o.soi));
                        var phi = Math.atan2((e*Math.sin(nu)), (1+e*Math.cos(nu)));
                        //eject = (270 - (phi*180/Math.PI)) % 360;
                       
                        // Kosmo-nots fix to maltesh's solution
                        eject = (90 - (phi*180/Math.PI) + (nu*180/Math.PI)) % 360;
                }
               
                $("#ejection").val("" + Math.round(eject*100)/100 + "°");             
               
                // warning for different inclination
                if (o.inclination != d.inclination)
                        $("#inclination-warning").show();      
                       
                if (o.speculated || d.speculated)
                        $("#speculation-warning").show();      
 
                draw(o,d,p,Math.round(phase*100)/100,Math.round(eject*100)/100);
        }





我不确定您是否需要其他任何东西，但感谢您的时间。

编辑

好​​的，我试过的相角：



I'm not sure if you need anything else but thanks for your time.
EDIT
Ok, for the phase angle I tried:

Dim t_h = Math.PI * Math.Sqrt(Math.Pow(originAlt + destAlt, 3) / (8 * parentMu))
Dim phase = (180 - Math.Sqrt(parentMu / destAlt) * (t_h / destAlt) * (180 / Math.PI))
phaseAngle.Text = ("" & Math.Round(phase * 100) / 100 & "°")



这是javascript的一部分：


Which is this part of the javascript:

var t_h = Math.PI * Math.sqrt(Math.pow(o.alt+d.alt, 3)/(8*p.mu));
var phase = (180 - Math.sqrt(p.mu/d.alt) * (t_h/d.alt) * (180/Math.PI)) % 360;
$("#phase").val("" + Math.round(phase*100)/100 + "°");



我应该得到44.36 °但我得到了-478.82°。

Btw phaseAngle是显示结果角度的tex框



我从xml获取数据file：


I should get 44.36° but I get -478.82° instead.
Btw phaseAngle is the tex box showing the result angle

I get my data from an xml file:

(\"#origin\").find(\":selected\").text()];
var d = data
("#origin").find(":selected").text()]; var d = data


(\"#destination\").find(\":selected\").text()];
var p = data[o.parent];
